Chosen Solution
I have a Samsung Galaxy A7 (2016) which was facing a screen flickering problem. The next time it fell off, my screen became unresponsive and gradually blacked out. In order to be more specific, first the screen turned into a violet colour gradually (starting from the top) and then completely blacked out. Though the screen is unresponsive but the home key and the volume keys still work. Also I can hear the sound of messages and answer calls with the home key. So i guess my phone is still working. Will replacing the screen solve the problem? or are there cheaper solutions? please help asap!!
If this happens after drop then you have a bad screen.
