While uncommon, this problem is a complicated one considering you really couldn’t do a thing when your Samsung Galaxy S4 refuses to turn on. There are a lot of factors that may have contributed to the issue. You can address them one-by-one when your phone turns on. Therefore, the very first thing you should do is bring the phone back to life no matter what.
Bringing Galaxy S4 Back On
Step 1: Plug the charger in. It’s a power problem so you should check the power supply first. There is a possibility that the battery was totally drained. Leave the phone charged for a several minutes before attempting to turn it back on. If the phone’s not charging, take the battery out for a minute, put it back on and charge it for minutes again.
Step 2: Boot to recovery mode. Booting to recovery mode is necessary when this problem happens to you. In there, you can always do a factory reset to bring the phone back to its original settings or clear data that were corrupted. All you need to do is press and hold the Power, Home and Volume Up buttons. Of course, you would need to have battery to do this that’s why this procedure goes second.
Step 3: Factory Reset. Just in case the phone boots up to recovery mode, do a factory reset. For those who are running custom ROMs, flash the ROM again to eliminate the possibility of corrupt system installation.
Step 4: Have a tech look at it. Without power, you can only do so much with your phone. So, if all these procedures fail, it’s time you had a technician check on it. If you’re under contract with a carrier, a new replacement unit might be provided for as long as you are under warranty.
