My phone started off with a little crack but recently I dropped it again causing a similiar crack on the side. The crack was not much larger than the first one and is on the side. When I tried to slide the screen it did not respond. I charged the phone, took out the battery and restarted it, pressed on the edges to make sure the digitiser was working and I ended up doing a factory reset and still nothing. I cannot slide the screen or even get into my phone. Someone help?
