Reasons why Samsung Galaxy S4 may not turn on
First, you need to make sure that the smartphone does not actually turn on, and is not just discharged. To do this, just put it on charge. If the Samsung Galaxy S4 does not turn on even when charging, then there are the following reasons for this:
- the power button is faulty. The charging indicator will be on, but the Samsung Galaxy S4 will not turn on;
- the power connector is out of order. In this case, the charging indicator light will not light up;
- the smartphone has been dropped or wet. If there was mechanical damage, then the smartphone will not respond to charging;
- replacement of software. In this case, it is possible that the Samsung Galaxy S4 will boot to the logo and freeze or reboot over and over again.

You may no longer remember about the fall or wetting of the phone, but the damage it received can lead to the fact that it will refuse to turn on after a certain period of time.
- Perhaps the most common problem that keeps the Samsung Galaxy S4 from turning on is software replacement itself. But not only it can cause this problem. This can also happen when installing updates, third-party applications or searching the Internet without antivirus. In this case, you need to reinstall the software on the Samsung Galaxy S4.
