What to do if the phone has rebooted. Why is my lenovo phone rebooting. Mechanical damage or marriage

The Android system is vulnerable to various kinds of threats. Therefore, the situation when the Xiaomi phone constantly reboots and cannot start appears in every fifth user. Such problems for users can occur regularly, which makes it problematic to use Xiaomi. If the phone constantly reboots itself, then you should not put an end to it, as this problem can be solved.

The situation when Xiaomi reboots by itself is called “bootloop” by IT people. The term translates as cyclic reboot. At the very beginning, the brand logo appears, and after that nothing happens. The operating system does not start for some reason, and then it starts to reboot itself.

Also, this problem can manifest itself from the other side. For example, a Xiaomi phone unexpectedly restarts itself. There is no clear pattern for such events. This is possible several times a day or during the week.

However, the device may turn off at inappropriate times. Often the causes of such failures lie in the operating system. Common Mistakes:

• OS corruption on MI5 or MI6. Such an error can occur if a person has edited axis files. If the user has gained root rights and his Xiaomi phone reboots and does not turn on, then the problem lies precisely in the operating system itself;
• update errors. Users are faced with such a situation when they upgrade to the global version of MIUI. Also, the phone may start to reboot on its own due to the installed shell with errors. Such situations arise when a user downloads an update to Xiaomi from third-party resources;
• independent attempts of flashing. Redmi may take a long time to load or even freeze due to an incompatible OS with the unit. In addition, the user runs the risk of downloading a version of the operating system with errors. Therefore, flashing a phablet should be trusted by experts;
• power off during update. Xiaomi may stop working due to a sharp decrease in the charge level during flashing. The manufacturer claims that updates must be carried out by connecting the phablet to power. However, there are situations when the flashing ends abnormally. Because of what the gadget stops loading;
• infections. A virus that is inside the OS can harm it in cases where root rights are installed on the system. In addition, there are separate non-working applications leading to "bootloop".

The remaining causes of failure are mechanical damage or a consequence of environmental influences. The gadget could fall, due to which the part in the case was damaged. In addition, if water gets on the phone, it may start to turn on and off constantly.

Sometimes due to damage. Especially if the RAM, processor or communication module is out of order.

Reboot related issues

There are 2 common failures of Redmi devices. In the first case, when the gadget is turned on, the MI logo appears on the screen. After a few seconds of waiting, it turns off, and then lights up again.

The second problem is that the gadget works in the usual mode, but at the most inopportune moments it reboots itself. Such shutdowns are repeated 2-3 times a day. There are also situations where the problem appears every hour.

Why the phone does not boot

Most often, if the gadget freezes on the logo image, then this indicates serious errors in the OS. However, Redmi can issue such a problem for a number of other reasons. For some users, the device may boot after a while. Reasons for this problem:

1. Replacing the main firmware via a PC or standard TWRP.
2. 2% percent of the battery or its breakdown.
3. Mechanical damage or liquid ingress into the gadget.

The best solution to such a breakdown is to use the services of experts from the service center. If the phone is under warranty, then you can take it to the store where the device was purchased. However, in this case, the user will have to wait 2-3 weeks for repairs.

If the user does not want to spend money, and the warranty card has expired, then you can try to solve the problem yourself. It is best to use a system backup. On some devices, it is done automatically. If the user spent it manually, then the gadget can still be saved.

How to fix your phone if it won't turn on

When the user has a backup of the system, you can try to restore the phone. To do this, go to the recamera section, and then format all the memory. However, the file where the copy of the OS is located cannot be touched.

In addition, in such a situation, you need to ignore the various updates that the manufacturer offers.

If backups were not created, then you can use another recovery method. To do this, you need to get a flash card from the phablet. After changing the firmware of the device. Thanks to this solution, you can understand what problem arose in the phone.

Before changing the firmware, you need to charge the phone to 100%. Experts recommend carrying out all procedures by connecting the gadget to charging.

If these methods did not help fix the phone, then it should be taken to a service center. Since problems with the firmware, after these troubleshooting methods, can be ruled out.

Why does the phone restart during work

There are only three reasons why the gadget turns off and on on its own while using it. In the first case, most often, people install non-working updates.

In addition, the user, by his own negligence, can delete the axis file. The third reason is the installation of malware or a third-party application that causes the phone to reboot.

Samsung keeps rebooting

Despite the fact that the Samsung Galaxy is the top model of the global brand, it, like many smartphones, can fail and start constantly rebooting. Such a breakdown may be caused by a malfunction in the operation of any program or operating system on which this phone is running.

A hardware failure can also cause problems, as a result of which the smartphone will constantly or periodically reboot.

note

This behavior of Samsung Galaxy will cause a number of inconveniences to the user, and in the worst case, it will lead to a complete loss of data on the mobile device and the inability to use the gadget for its intended purpose.

What should I do if my Samsung phone keeps restarting? Let's consider several reasons for such a malfunction and try to find ways to eliminate it.

Causes of Reboot and How to Fix Them

Many users, as well as more experienced service center specialists, identify several main reasons why Samsung Galaxy constantly reboots:

• breakage of power contacts or lithium-ion batteries;
• mechanical damage to the phone;
• failure of the system board as a result of oxidation of contacts or conductive connections under the influence of moisture;
• failure of the RAM module or processor;
• incorrect operation of one or more applications;
• destruction of the core.

We will try to independently identify several reasons for the phone to malfunction and, if possible, fix the problem without resorting to the help of experts or a service center. First you need to determine the nature of the malfunction, that is, what caused it.

All types of breakdowns can be divided into 2 types:

• mechanical damage- occur if any of the parts of the phone fails;
• software problems- caused by incorrect or incorrect operation of any system application or third-party program on the phone.

note

In the event that the Samsung Galaxy constantly reboots, responding to user actions (for example, by pressing a finger on the screen sensor), it must be put into safe mode. With this launch, the device loads only basic system applications.

All extraneous programs set by the owner of the handset after activating the device, in this mode will be forcibly disabled.

Safe mode

Activating Safe Mode on all Samsung Galaxy phones is done in the same way. As an example, consider how this is done on the Galaxy S6 Edge model.

To enter safe mode on this device, you must:

• Hold down the power button and select the "Power Off" option. Wait until the screen of the smartphone completely goes out and does not show any action.
• If the model of the problematic gadget has a removable battery, then the easiest way to turn off the phone 100% is to remove the lithium battery and leave it in this position for a few seconds.
• Replace the battery and turn on the Samsung Galaxy phone.

It is important to know

At the time when the manufacturer's corporate logo appears on the screen, it is necessary to hold down the lower volume carriage key, that is, the "Volume -" button. If all the steps were performed correctly, a corresponding inscription will appear on the screen, which will inform the owner that the phone is loaded in safe mode.

After the final download, you need to perform any actions with standard applications, for example:

• open file manager;
• view the amount of memory;
• check settings;
• download system updates ();
• use a standard Internet browser;
• record a video, take some photos, etc.

If, when performing such actions, Samsung does not reboot, there is a very high probability that third-party applications that did not belong to the official software provoked incorrect work. This method of verification gives about 90% accurate identification of the cause of the breakdown. In other cases, the fault should be sought in the mechanical or hardware.

Machine breakdowns

If the device worked adequately in safe mode, and when switching to normal mode, the situation resumed, the question remains what to do: the Samsung phone constantly reboots as before. You should start looking for mechanical damage from the removable parts of the mobile device. This may be a battery that has been deformed due to the destruction of an electrical element. By visual inspection, it is necessary to determine whether the thickness of the battery plate has increased, whether extraneous swellings, dents or cracks have appeared.

If a standard household voltmeter is available, it will not be superfluous to check the internal capacity of the battery. This procedure should be performed after the battery is fully charged, as a result, there may be 2 results:

• the sensor will show 4.0-4.2 V - the battery is in good condition;
• the value will be equal to 3.7 V - the battery is discharged.

As a result, the reason for the reboot of the Samsung phone lies in low or insufficient power. In this case, the battery should be replaced with a new one.

Another reason for turning off or restarting the smartphone may be a small gap between the back cover and the battery.

note

If the phone turns off during a call, that is, when it is in a vertical position, this is most likely caused by loose contact between the battery and the electrical circuit.

You can check and fix this breakdown in an elementary way: lay a thin layer of paper between the battery and the back cover.

What to do if the Samsung phone is constantly rebooting, and the battery and its contacts are in good condition? The reason for the reboot may be mechanical damage to the internal parts of the mobile device due to a strong impact on a hard surface. As a result of falling the phone, detachment of connecting or contact wires, thermal soldering or any other component is possible. The motherboard, to which all the main elements of the gadget are soldered, may also crack.

Will be useful

It is not recommended to repair the phone on your own in this case. It must be taken to a service center for a complete diagnosis, as this procedure requires special equipment and extensive experience.

Software crashes Samsung Galaxy

If an experienced technician or service center may be required to correct mechanical problems, then
software problems can be easily solved at home. The main task is to pinpoint the cause, namely the application that is causing the system crash.

There are 3 main causes of software-related breakdowns:

• software conflict between the application and the official Android operating system;
• incomplete or incompletely installed program update;
• virus applications (spam bots) or malicious software (trojans);

Let's consider each of the situations in more detail.

Installed software conflict

If after bypassing the Play Market, the user found that phone started rebooting, then the problem of the malfunction lies precisely in this software.

Remove the conflicting program. You need to go to section "Applications", find the problematic utility, and after opening the dialog box, click the button "Delete". Having performed such a rather simple algorithm, take into account the fact that the remnants of the program may remain in the RAM of the device.

You can finally eliminate the application through the standard service section recovery mode:

• Turn off your smartphone.
• Press 3 keys at the same time: "Nutrition", "Home", "Volume +".
• In the Recovery menu that opens, by pressing the volume buttons, go down to the item wipe cache partition and start the cleaning procedure.
• When done, click "reboot system now", which will allow you to restart your phone normally.

Incorrect app updates

Frequent reboot of the smartphone can affect the quality of standard applications such as google music, maps, camera, standard browser, play market and so on. New software versions may not be compatible with the existing phone model.

Identifying such software will be quite simple: it will continuously require updates, over and over again. To resolve the issue, follow the steps below:

• Through the settings menu, go to the section "Applications".
• Turning over to "Systemic".
• We find the desired program.
• Open its properties and click the following buttons: "Clear cache", "Erase data" and "Uninstall Updates".

This article will tell you about the reasons why your Android phone or tablet reboots itself and what to do in this case.

This article is suitable for phones and tablets of all manufacturers of Android devices: Samsung, LG, Sony, Huawei, Xiaomi, HTC, ZTE, Fly, Alcatel and others. We are not responsible for your actions.

When, after the fall of the tablet or smartphone, it began to reboot on its own, the reason is that some element has failed or the power circuit has broken. You can drop any gadget, but the repair process can be more difficult.

Some companies may refuse to repair at all, while others will only make paid repairs. For example, if you have problems with a Samsung smartphone after a fall, then you first need to make a call to the hotline 88005555555 to clarify whether it is possible to repair the product. Often, service centers go to a meeting, but the user pays for the repair at his own expense.

A smartphone or tablet can be taken to an unauthorized service. Such centers should be chosen according to reviews, so as not to fall for the "hack". Often, as a result of a fall, the case still breaks, the screen breaks, so in this situation you simply cannot do without a service center. Experienced users can, if spare parts are available, repair the gadget on their own.

The reason for rebooting Android is the battery

This reason is the most common and manifests itself on new and used phones. It is necessary to consider not tight contact of the battery with the telephone contact group and a low-quality battery.

Increase

If the reason for the reboot is related to the battery, then at some point the modules are not supplied with energy or it is not distributed correctly, which can lead to an automatic reboot. As a result, the gadget can reboot itself.

The lack of energy is caused when the device heats up while working in applications or when playing games, when power is not supplied correctly during a call, contact is lost when shaking. The concept of a defective battery:

• Manifestation of signs of "bloating" and oxidation.
• Consequences of moisture getting under the body.
• Over time, the natural deterioration of the battery.
• The use of low-quality non-original batteries.
• Defective original battery (for example, the situation with Samsung Galaxy Note).
• The consequences of using a non-original charger, which may damage the power controller or charger. As a result, the gadget distributes energy incorrectly, in an emergency it reboots itself.

The battery, like any storage device, is calculated for a certain number of discharge and charge cycles. If the device is constantly charged, then it will simply lose its potential and the charge will not hold.

Such a drawback is available for Li-Pol models, which have a "memory effect". It is required to charge them up to 100%, and then discharge to zero, after which you can put them on charge again. Li-Ion drives do not have such a flaw.

The critical point is the need to use only the "native" charger. This is due to the current strength indicated on the charge. When the manufacturer specifies, for example, 1A, then this value cannot be exceeded.

You do not need to use more powerful analogues for 2A or 1.5A, since you can break the battery much faster, it will simply swell. With proper use, the average cycle is approximately 1.5 - 2 years, and then the battery begins to lose its properties.

You can also note the case that Samsung on Android rebooted when the user tried to type something on the on-screen keyboard. It turned out a simple tapping on the screen, due to which there was a loss of contact between the battery and the contact group of the gadget.

Reboots after falling water

For a gadget, water is a huge problem if the smartphone is not protected. In 90% of cases, moisture ingress guarantees that the device will fail. The contacts are oxidized, in a similar situation, in the place where moisture gets in, it can “short. After hitting water, the device is able not only to reboot, but also not to turn on at all.

In this situation, service diagnostics are necessary, and often the cost of repairs is the same as the price of a new gadget. Due to the ingress of water, it is necessary to replace the system board or a component that has been exposed to moisture.

The service center and the store will refuse to repair, as the operating conditions of the device have been violated. It is not a fact that after repair work the device will function normally. Therefore, it is best to purchase a new smartphone or tablet here.

Firmware issues

Firmware is the replacement of the native operating system of the device with a modified or more recent one. There are 3 firmware options:

• Test.
• Custom.
• Official.

When errors occur in the native firmware of the device, you can reset it to factory settings, which helps in 90% of cases. You can also check on the Internet which versions of Android are currently the most relevant. The update process is carried out without your intervention on its own, so no skills are required.

Increase

With custom firmware, the situation is more complicated. Cyanogen Mod can be considered the only stable firmware, but the development team broke up, and the rest of the team renamed itself Lineage OS. They make decent developments, but there is one drawback: the firmware is installed at your own risk. You need to be prepared for CPU overheating, reboots, unstable modem operation, GPS, battery and other key components that affect stability.

There are plenty of test firmware on XDA, w3bsit3-dns.com and others. If you know in advance about OS problems and want to be a "guinea pig", then you can install them on your gadget. Such firmware can damage the device, not to mention cyclic reboots.

Android restarts after installing SIM card

Increase

There are a lot of complaints on the Internet that Lenovo smartphones reboot themselves after installing a SIM card. A similar problem is possible on gadgets from other manufacturers. A possible solution is to replace the SIM card with a new one. If you have been using the SIM card for several years, you can upgrade to a new firmware or reset the settings.

If, when replacing the SIM card with a new one, the reboots did not stop, then the problem is related to the device. You can experiment and select only the 2G or 3G operating mode. To do this, go to the engineering menu by entering the combination *#*#4636#*#*.

In some gadgets, it is possible to set only 2G or 3G mode in the settings menu. In some modern devices, this function is blocked, but you can set the priority of work. If the problem disappeared, then the error most likely lay in the radio module.

Memory overloaded or problem with flash memory

After physical damage (power surge, moisture, shock), the flash memory module may fail. As a result, during the loading of the gadget, it will “fall”, which will lead to a system crash. Reboots are carried out and the smartphone works again until a certain point.

There may also be a reason for rebooting the RAM with installed programs. Many users of the application do not close, but simply minimize them using the Home button. As a result, these applications remain running in the background, consume energy and RAM.

Here, braking and loss of tablet / smartphone performance is still possible. To solve the problem, you should clean the RAM in the built-in way or with special applications.

Other Reasons to Reboot Android

It is necessary to check the memory card, if there is one in the device. Quite often, the problem can be related due to a faulty memory card. The first thing to do is to format it, it is advisable to use ExtFAT or FAT32 formats.

Do not use cleaners for Android. After running different cleaners, you can not only lose your own files, but also break the device. In this situation, resetting the settings or firmware will help. The best cleaner for a gadget is to backup information and reset to factory settings.

One of the obvious options for rebooting a product on Android is to infect it with malware. To check the gadget for viruses, you must use applications that analyze the entire system.

Do not use dubious software, especially launchers designed for the desktop. Such applications are capable of causing system crashes in Android devices.

If you made a change in the processor frequency, you must return everything as it was. This problem affects devices that have been rooted to optimize system performance.

The constant and unscheduled reboot of your Android smartphone is an annoying mistake. It gives rise to a bad mood and a desire to part with the gadget. A quick and effective solution in this case is a visit to a repair shop with free diagnostics. But there is not always time for this, so first we will try to fix the problems ourselves.

Quick Methods to Fix Failed Reboot

It often happens that the phone reboots during the charging process. In this case, we recommend using the "native" charger. Another type of failure is a reboot after installing / replacing a SIM or SD card. They need to be changed and / or flashed (updated) Android OS.

It happens that turning off / on occurs in the cold - this is a short-term phenomenon. After moving to a warm room, everything falls into place.

Another type of problem is disconnection and return to the previous state during a call or conversation. In this case, you can try turning off the 3G network, resetting the settings, or changing the SIM card, especially if it is in the Micro-SIM or Nano-SIM format.

Why does the phone restart itself?

There are many reasons for a sudden reboot:

• viruses,
• mechanical damage,
• software crash,
• iron problems,
• sticking of the power button due to improper operation of the device.

Before you take the big steps, do the easy ones, like checking for viruses or replacing the battery.

Note! If the power key is stuck (this is possible if you constantly pressed it with wet or sweaty hands), wipe it and the contacts on the charger with nail polish remover without acetone, or better, soak them for 20-30 minutes in a solution.

How to fix reboot issues

Let's look at ways to fix common problems that cause the phone to reboot. You can do them yourself.

Virus infection

A smartphone is no longer just a device for communication and entertainment, but also a real “bank in your pocket”. With it, you can pay for purchases, make transactions with cards and accounts, etc. It is not surprising that scammers regularly come up with new ways to steal information.

So, to check for viruses:

Kaspersky Internet Security has a good reputation, so let's consider a process based on this antivirus.

The battery is running low

The battery cannot last forever. Over time, or from improper operation, its resource is developed, after which it must be changed.

Battery replacement

The battery can be easily replaced if it is removable. Buy a new one and replace with the same places, and first check the fit (poor contact) and perform a visual inspection for deformations.

If the battery cannot be removed, send it to a repair shop for replacement or, if the warranty service has not yet ended, to a specialized center where the battery will be replaced free of charge.

Battery calibration

It is not always necessary to immediately change the battery if the phone reboots by itself. Sometimes it makes sense to calibrate it. For this:

1. Discharge the phone to zero, then turn it on again and wait for it to turn off;
2. Insert the charger into the socket and leave the smartphone until fully charged (do not turn it on);
3. Turn off the charger and turn on the phone. If the charge is not enough, connect it again and bring the level to 100%;
4. Unplug your charger and reboot your device. If the charge is not enough again, reconnect the phone to the network. Do this until the charge level reaches 100%;
5. Repeat steps 1 and 2.

Failed software update

The phone frequently reboots due to a software glitch. To fix the problem, you can return the smartphone to factory settings or update the firmware.

Installing the update

Reset

Reset settings are performed in this way:

Mechanical damage

The permanent reset could occur after being hit if you dropped your phone/hit your classmates with it/used it as a projectile to throw. The result may be damage to the printed circuit board. A complete replacement of the part or re-soldering of its elements will be required.

If the methods listed above did not correct the situation, there is a possibility that mechanical damage is the reason for the constant reboot. There is only one option - to take the mobile phone in for repair.

By the way, the reason why the phone constantly reboots may be a factory defect. You have the right to terminate the contract of sale and return the money or demand the replacement of the goods with a similar one. In any case, the decision will be made after the examination. In the meantime, it is being done - read the law "On the Protection of Consumer Rights", specifically - the section on the return of technically complex goods.

Constant reboot is a fairly common problem of modern smartphones, especially noticeable in the cold season. Devices are simply not designed for operation at sub-zero temperatures. Note that hypothermia is far from the only reason for endless or frequent “resets”. The source of the problem can be both the fall of the device and software malfunctions. The following describes what to do if the phone itself restarts without stopping.

There are several main reasons for frequent reboots.

• Mechanical impact on the body of the smartphone - a fall or a strong blow.
• Failures in the operating system. This includes both errors after installing incompatible firmware and updates, and the malfunction of certain programs.
• Failure or significant loss of battery capacity. The situation is relevant both for old devices and for new ones - but with low-quality batteries.
• Malfunction of the motherboard modules responsible for power supply.
• The ingress of liquid into the phone case, which resulted in the oxidation of elements and the appearance of rust.
• Hypothermia or overheating.

Problems can be caused by both software and hardware malfunctions. Mechanical damage disables device components, causing frequent resets.

An unusable battery is one of the main causes of such a defect. To check the battery, remove it from the smartphone and inspect it carefully. If bulges or visible damage are visible on the surface, the battery should be disposed of and replaced with a new one. Swollen batteries cannot be repaired, but in some cases their life can be extended:

• Using a flathead screwdriver, pry off the sticker from the front of the battery. Disconnect the chip and set it aside, but do not tear off the controller contacts.
• Using a thin needle, gently pierce the battery from the side where the controller board used to be.
• Press the battery with a heavy object larger than its body. Release the accumulated gas, but do not damage the battery.

Important! The above method will help extend the battery life by a few days, but the battery should be replaced as soon as possible.

If the problem was in a faulty battery, reboots will stop for a while. The only way to completely eliminate the defect is to replace the battery.

Phone reboots on Android startup

If your gadget restarts every time you turn it on, the following methods may help.

• Perform a hard reset via Recovery. On models from different manufacturers, the entrance to Recovery is slightly different. A universal method - when you turn on the phone, hold down the "Volume down" and lock buttons, when the Android icon appears, release the volume down. Navigate the menu using the volume switches and the power button. Select "Wipe data/Factory reset", then confirm the selected action. Reboot the device with the “Reboot system now” command - the problem will disappear if the endless reset is caused by incorrect firmware.
• Disconnect the battery and leave the device off for 20-30 minutes. Then put the battery back in - in some situations, the method can help.

Important! After a hard reset, all your data, accounts, photos and other personal information will be deleted. Carry out the procedure if the gadget reboots due to errors during firmware or updating.

When turning on the camera

The camera app causes reboots on older iPhones after updating IOS to the latest version, and in case of virus infection. Check the device with an antivirus or roll back to a previous version of the system to fix the problem.

After activating the GPS

Some Android smartphones may restart when turning on the GPS navigation system. The main problems and solutions to such a defect are described below.

• Old SIM - card: some smartphone models are incompatible with the SIM cards of some operators. Try replacing the SIM card with a new one or contact the service center of your mobile provider.
• Memory card: SD - card can also cause a reset when you turn on the GPS. Remove the storage media from the phone and check if the problem has disappeared.
• Wrong actions during firmware: perform a Hard Reset if the gadget reboots after installing a modified version of the OS. How to perform the procedure is described in the picture.

When Bluetooth is turned on

Instant reset after activating the file transfer function is a common problem with HTC models.

1. You can fix the problem by performing a Hard Reset, but in this case, your information and accounts will be deleted.
2. Bluetooth usually takes a few seconds to turn on - try turning it off the next time you reboot your device. Access to the option is possible through the "curtain" of notifications - as soon as Android and the main menu are loaded, turn off the transfer of multimedia data.

When talking

If the gadget performs a Reset during a conversation, check the battery contact with the main board. Perhaps, after a long operation, a gap appeared between the battery and the connector, which can be eliminated by attaching the battery to double-sided tape.

When launching applications

Some programs cause Android to restart due to poor optimization or runtime errors. The simplest and most effective solution is to remove the "problematic" application. Perhaps the problem is not in the program itself, but in certain drivers or the OS does not work properly. In this case, a full reset will help.

When connected to a PC

If the gadget restarts after connecting to the computer, check for the following problems:

• The USB cable is connected correctly and the cord is not physically damaged.
• Android phone or Windows PC is not infected with malware.
• Your computer has compatible drivers installed. If for some reason the utilities necessary for the operation of the device are not loaded, download them manually from the manufacturer's website.

Conclusion

Android and IOS smartphones can restart for various reasons. In some situations, the malfunction is caused by incorrect firmware or applications, in others, by physical damage to the device casing. Repair of the software part can be done at home, but in other cases it is advisable to contact the manufacturer's service center.
