Some owners of smartphones Samsung Galaxy S7 Edge complain about the problems when upgrading to the version of the operating system Android Nougat. After downloading and installing, a reboot is performed, but instead of the home screen, the screen remains black.
During the upgrade, the cache and data may be damaged, resulting in the smartphone not being loaded as expected. This is the reason for most of the problems that users face soon after the operating system upgrade, regardless of the scale of this update. Possible solutions are described below.
Step 1: Force reboot
This is about the same as the usual reboot, only here the battery is simulated. If you previously had smartphones with removable batteries, you could get the battery and install it again when you hung up. The Galaxy S7 Edge battery is not removable, so you have to use a bypass maneuver.
Press and hold the volume control down and simultaneously on the power button for 10-15 seconds. If the battery is not fully discharged and the problem lies in a recent update, the device will then reboot. Otherwise go to the next steps.
Step 2: Charge your smartphone
You need to make sure that the smartphone reacts when an electric current passes through its circuits. If not, the problem can be hardware, including a battery. Perform the following procedure:
- Connect the charger to the wall outlet.
- Using a cable, connect the smartphone to it.
- If it does not react, leave it charged for at least 10 minutes.
- If it is not charged, press and hold the volume control down and the power button for 10-15 seconds during recharging.

- When the Samsung Galaxy S7 Edge appears on the screen, release the power button and immediately press the volume control down.
- Hold it until the restart is complete.
- Release the button when Safe mode appears in the lower left corner.

- On the Home screen, click the Applications icon.
- Go to Settings> Backup and Reset.
- Click Reset Settings.
- If security is set on the lock screen, enter the password or pin code.
- Click Continue.
- Click Delete All.

- Turn off your smartphone.
- Press and hold the Home button and volume control up, then press and hold the power button.
