Why does my iphone 5 keep spazzing out?

Okay well three days ago I dropped my phone and It fell. This cause the screen to have cracks but it was still working fine. I went to a place in the mall call cell plus for them to repair it. The guy did repair it and when I got it the phone was fine but when I soon arrived home it started glitching and spazzing out. I can't even type in my password without it pressing random and numbers and on my homescreen it touches random things. I don't know what to do so people help

Two resons it was not calibrated probably or you had the ios 7 installed if that is the case check below links for solution

  • Why does my Wi-Fi keep going out? I have a Netgear as my Wi-Fi and i have a window 7 toshiba computer i think the problem is coming from the laptop because my iphones and andriods and everything else tht uses Wi-Fi works. But my laptop works for a certain length of time and the Wi-Fi will just cut off in the middle of doing something, it first has a yellow trigangle and it said no network found. Is there any suggestions on fixing this or anyone know how to fix it. Oh and also when i press it sometimes says limited access.

If I try to take a picture it tells me I don't have enough storage to take a picture.
