    This completely ruined my S7. Now I can't turn it off or factory reset. What do I do?

    You have to connect the device to a computer and use ADB Shell to change the resolution back to original. Messing with Android system files can and most likely will brick your device. Always think about that before changing anything.

    On Windows, you need to enter .\ before you run a program from command prompt or Powershell. In this case, you need to enter ".\adb shell" and it will start the connection with the device. You should have a new prompt where you can enter the rest of the command from above.

    If you booted it in safe mode, then you can't use the device normally. Long press the power off button and turn off the safe mode. Or take it to an expert and have it repaired if that doesn't fix it.

    What do I do if the screenshots don't take the complete screen on my Android device?

    Change it back. If you're using 1920x1080, then set your screen resolution to 384 DPI. Also the 1st method does not alter the resolution it only changes the DPI which is not the same thing. It's similar to changing the text size on Windows 10.
