Solution: Second charger
To check if the charger is in working order, connect the mobile phone to another charger. If charging has started, you can safely throw out the first charger - it is definitely broken.
Battery malfunction
On average, the phone battery is designed for 2.5 years of use. If your phone was purchased more than 3 years ago, the battery may have run out.
Solution: Battery replacement
With a removable battery, everything is simple - go to the nearest mobile electronics showroom and buy a new battery. But with a non-removable battery, you will have to go to a service center.
Problems with charging contacts
Another common reason why the phone does not turn on is broken contacts, due to which even a working battery will not accumulate charge.
Solution: Diagnose and fix contacts
Check the contacts that connect to the battery - they may have come off a little. In this case, take a thin pair of tweezers and slightly bend the tendrils of the contacts. If you have a special screwdriver for electricians, its indicator will show if there is voltage in the charger connector. Although in an amicable way, it is better to contact a professional master with this problem.
Influence of outside temperature
Winter and summer are a real challenge for anyone touch phone... The fact is that mobile devices do not tolerate high and low temperatures.

We hope you don’t have to use these tips, and your gadgets will work without interruptions and any problems.Has your smartphone suddenly stopped turning on and shows a black screen? There are several ways to fix this problem at home. Bringing an Android smartphone back to life is a little easier than an iPhone. If you have an iPhone, then it is best to contact a specialist, for example, to repair an iPhone Xr in St. Petersburg. But owners of Android devices should read our tips!
Take out the battery
This step is only worth doing if you have a removable battery. Take the battery out of the smartphone for a few seconds, then put it back in and try turning it on again. This is the first thing to do, since further steps will be based on the understanding that you have already completed this item. Owners of devices with a built-in battery should skip this point.
Reboot your device
Seven troubles - one reset. But the smartphone does not turn on. Fortunately, there is a special mode that allows you to get your phone out of its stupor. To enter this mode, simultaneously hold down the volume rocker and the “Power” button for 10 - 15 seconds. If you get into the recovery menu, just reboot from there.
Recharge
Sometimes the smartphone does not turn on because it is discharged. Before installing the device on charging, clean the phone and charger connectors with a toothbrush, keep the smartphone warm if you came from a cold place and then connect the charger to the phone. If after 15 minutes of charging, the smartphone does not turn on, then try charging the smartphone with another charger.
Nothing helped?
Removable battery
If you have a removable battery and you have completed all the points, then you just need to contact the service. Since available ordinary user resuscitation methods have already ended.
Built-in battery
Owners of smartphones with built-in batteries can, at their own risk, try to disassemble the device, disconnect the battery cable and connect it back. After that, put the device on charge. If the charge is on, then everything is fine, wait a while and you can turn on the smartphone. If the charge goes and stops immediately, disconnect and reconnect the battery cable and set it to charge. Continue until the phone starts charging normally. It is more correct, of course, to "push" a battery that has gone into a deep discharge with a strong current from laboratory unit nutrition, but not everyone has it.
As a result of a hardware breakdown or an OS malfunction, any Android smartphone may stop responding to the power button. A common problem can be called when the phone does not turn on beyond the screen saver. In this case, the screen shows the logo of the manufacturer or the standard "green robot" of the Android system, but then nothing happens.
If the gadget hangs on the splash screen, there are 4 main reasons for the defect:
- Android operating system glitches.
- Critical hardware failure due to water ingress, board overheating, or severe shock. In this case, Android can start downloading and finally fail.
- Incorrect actions when installing custom firmware, resulting in the failure of the operating system.
- Memory card incompatible with the device.
- Short-circuited sim card.
- Insufficient free memory, slowing down the startup process. In this case, the phone is loaded, but very slowly: within 3-5 minutes.
The phone is frozen on the startup screen saver
What you should definitely not do is disassemble the case yourself in an attempt to determine the cause of the breakdown. Without the appropriate skills, you can not only lose the guarantee, but also finally "kill" the device. If you accidentally flooded or dropped the gadget, contact an official service or a reliable master for help.
We take out the sim card
It works almost 100% of the time, first we try to remove the SIM card and boot without it.
We take out the memory card
Be sure to remove the memory card from the device. Almost half of all power-up glitches are due to this small memory chip. How to do it correctly, see the instructions for the device, universal way there is no.
Software malfunctions
The most common reason for freezing is when Android does not load beyond the logo. To fix the problem, try entering Recovery Mode:
- For Samsung Galaxy with Bixby button - Hold down the Power, Volume Up and Bixby switch at the same time. When Samsung appears on the screen, release the power.
- For the rest of Samsung gadgets - press the volume up and down buttons, as well as lock, then wait for the download icon to appear.
- LG - hold down the volume down control and turn on, after turning on the screen, release it.
- HTC - the manual is identical to LG devices.
After getting into the Recovery menu, which is navigated using the hardware buttons, you can take the following actions:
- Clear the cache by selecting Wipe Cache Partition using the volume rocker and lock button.
- To produce full reset to factory settings by deleting all data. The Wipe Data / Factory reset option is responsible for this action. Please note that doing so will erase all your data and return the device to the factory state.
- After making the necessary settings, select Reboot System Now to attempt a reboot.
Reflash device
If the above steps did not help in any way, it remains only to flash the device manually using a computer and special programs... For example, for Samsung, this is the Odin utility. For each device, the instructions and the firmware themselves are different, necessary information exactly for your phone can be found on the forums.
How to determine if a battery is healthy
A common cause of problems is battery failure. It is quite easy to identify the defect: if, when connected to the power adapter, a charging icon appears on the screen, increasing the charge level over time, everything is fine. But if, when the charger is turned off, the gadget stops responding to button presses or refuses to charge at all, then the problem is probably in the battery or power connector. In this case, the only correct solution is to contact the manufacturer's service center. For example, for owners Samsung line Galaxy warranty service held in Samsung centers.
Infection with viruses
Quite a rare cause of serious damage. At the same time, there may be extraneous pictures on the smartphone screen, instead of the download icon.
Solution: check with a third-party antivirus by connecting your smartphone to a PC.
If you suspect that malware has entered the system, you can try to find information on how to remove specific types of viruses on the forums of well-known antivirus product developers: Dr. Web, Kaspersky and Nod32.
Conclusion
The smartphone freezing during the download process can occur for a variety of reasons. In some cases, it is possible to solve the problem on your own, in others, only contacting the service center will help. Repair cell phones is not an easy task, and it should only be trusted by trusted professionals. You should not look for help in the nearest market or try to disassemble the device with improvised means - this will only harm and void the warranty. To avoid similar breakdowns in the future, remember a few simple rules:
- Do not flash your smartphone with Chinese "left" firmware without sufficient experience.
- If you find a defect, do not panic and do not try to disassemble the device.
- Use antivirus software and regularly check your smartphone for malware.
