The Samsung Galaxy S7 is a powerful handset and Android Marshmallow is an accomplished operating system. Despite that, issues arise with some users that cause frustration and the so-called ‘black screen of death’ is one of them. If you have experienced this issue and want to fix the black screen after turning on your Samsung Galaxy S7, here’s how to do it.

It usually goes something like this, you reboot your phone, you see the Samsung logo appear on screen and then nothing. The screen goes black, the phone doesn’t respond and nothing works. This is a sign that the phone couldn’t load the operating system. It could be a hardware issue or an app or software but we won’t know that until we can get it working and troubleshoot.

Here are a couple of things to try.

Reboot into recovery mode
1. Power off the Galaxy S7.
2. Press and hold the volume down and power button until you see the Android System Recovery screen.
3. Navigate using volume keys and select options using the power key.
4. Select Wipe cache partition.
5. The phone should automatically reboot.

Many users have found that a simple cache wipe clears up their issue and at least lets them into the phone to troubleshoot further. Now would be a good time to check running apps and disable any new ones installed just before this started happening.

If the cache wipe didn’t work, try this:

Factory reset to fix black screen issues
A factory reset is the move of last resort. It wipes all your personal data from your S7, restoring it to factory defaults. Back up your information if you can get the phone to boot before performing these steps.

1. Power off the phone.
2. Press and hold the volume down and power button until you see the Android System Recovery screen.
3. Navigate using volume keys and select using the power key.
4. Select Wipe data/factory reset and confirm.
5. The device should automatically reboot.

If a factory reset doesn’t remedy the black screen issue, it is likely to be a hardware fault. It’s now time to dig out your warranty and follow up with your provider.
