We did the not charging issue article first as battery is very essential when troubleshooting. Needless to say we cannot troubleshoot a device that won’t turn on or doesn’t charge when it drains its battery. In the world of smartphones, power is king so a beautiful smartphone like the J7 will become just another expensive paperweight lying on your table if it doesn’t turn on or charge.

Now that we’ve established, the importance of the battery or power on your smartphone, it’s time we present the possibilities why your device won’t turn on and we will base our troubleshooting on those possibilities:

System crash caused the device to freeze leaving it with a black screen that’s unresponsive
The battery got totally drained that it can no longer power the device up even for a few seconds
Some caches or data files got corrupted for some reason and caused the phone not to respond
The device sustained some serious liquid and/or physical damages that’s preventing it from booting up

Now, based on these possibilities, here’s what you need to do:

Troubleshooting Galaxy J7 that doesn’t turn on

Step 1: Verify it’s not just a system crash issue

One of the good things with the J7 is that it has a removable battery. It’s something you should be thankful for because you can isolate what the problem really is. So, the first thing you need to do is to perform the battery pull procedure, which, by the way, is very effective in fixing minor firmware and hardware glitches. Here’s what you need to do:

Open the back cover.
Pull the battery out.
While the battery is out, press and hold the Power key for a minute.
Replace the battery and secure it with the back cover.
Attempt to turn the phone on.

If the phone turns on after this very simple procedure, then the problem was caused by a simple firmware issue.

Step 2: Try charging your Galaxy J7

If the problem persists after doing the first step, then try to charge your phone to rule out the possibility that the problem is caused by a drained battery. Aside from the obvious reason, you will also know if it responds when it detects that current is flowing through the circuits. If it doesn’t, then you should first address the non charging issue before you continue your troubleshooting. The phone should be able to charge first, read this post here: How to fix your Samsung Galaxy J7 that won’t charge, other charging issues [Step-by-step Troubleshooting Guide].
If you can bring the phone to charge, then leave it plugged in for at least 10 minutes before trying to turn it on. If it doesn’t turn on but charge, proceed to the next step but if it neither charges nor turns on, it’s time you send it in for checkup and/or repair.

Step 3: Try booting the phone to different modes

You do this if the phone charges but still refuses to turn on. You’re actually trying to find out if the phone would boot up when all third-party apps are disabled or if it powers on when the Android interface isn’t loaded. So, try to boot up your J7 in safe mode first, here’s how…

Press and hold the Power button (located on the right) until Phone options is displayed then release.
Select and hold Power off until the Reboot to Safe Mode prompt appears then release.
Tap RESTART. Note: This restart process may take up to one minute to complete.
Upon restart, Safe mode appears in the lower left of the unlock/home screen.

If the phone boots up in this mode, then the problem is solved partially, or at least, we know it still powers on and that’s something. But if it won’t power on in safe mode, then try booting it in recovery mode and if successful, continue wiping the cache partition:

Power off your Galaxy J7. Press and hold the Power key, tap Power off and then touch POWER OFF to confirm.
Press and hold the Volume Up button and then press and hold the Home key. While holding both, press and hold the Power key.
When the Android logo appears on the screen, release all three keys. It may take a minute before the Android recovery screen appears.
While on Android recovery screen, use the Volume Down key to highlight options, in this case, highlight the option ‘wipe data/factory reset.’
Press the Power key to choose the highlighted option.
Press the Volume Down key until ‘Yes — delete all user data’ option is highlighted.
Press the Power key to confirm the reset.
Once the reset is complete, press the Power key to choose ‘Reboot system now.’
The phone will restart a little longer than usual and the reset is finished.

Step 4: Seek assistance from a technician

If the device refuses to turn on after steps 1 to 3, then there’s nothing much you can do about it. It’s time you sought assistance from a technician or from your service provider. Bring the phone to a local shop or to the store where it will be checked and tested by a tech.
