My screen is unresponsive to touch
So I dropped my iPhone a while back and the entire right half of my screen won't respond to touch. So I've tried restarting, restoring and updating my phone, and nothing has worked. So I've resorted to trying to drop it and get the piece that was disconnected to reconnect and I think I've made the problem worse. Now not only does it have 5 pinkish/white lines on the right half of the screen, it it has horizontal lines throughout the entire screen ( like when you there's no channel on an old TV)
What do I do? Can I fix it myself or did I just destroy it? I've seen sort of similar circumstances and people have said to take into a store, but I probably can afford to get it fixed that way.. Any advice?
