@forsale since it does come up properly and seems to work alright for the first few seconds, I would look at the proximity sensor and see if that is not turning your screen off. See if you can enable it in your software settings. Also, if you have a screen protector on your phone, take it off and see if that makes a difference. Of course, you can never really rule out the screen being damaged or the video circuitry having issues, but stat with the simple things first.
