Frozen and lock screen changed to squares?
So today I tried repairing the battery on my iphone 5c,which I successfully did and replaced battery.Problem is that my phone is now frozen and and my screen is not working when I try to open it or move anything with my finger .Also my lock screen changed to a bunch of tiny squares .I can still see my messages coming in on my lock screen but can't respond cause screen isn't working while I try to unlock or even try to turn off .Please help any advice will be appreciated .
