You say “i recently bought an iphone 5s from apple not even 1 month ago”. If you did indeed buy it from Apple, then I would return it to them for a replacement.

The screen doing this is usually a strong sign of long screw damage, that us where internal screws have been put back in the wrong place causing damage to the logic board, there are some people out there than can repair this,
