Phone Keeps Pressing Things By Itself
So I am currently using an LG Optimus Zone 3. I'm stuck with this one until I have enough to buy a better phone. Anyway, my phone has been acting up for some reason. I don't know why, but my phone just keeps pressing things by itself and sometimes when I try to put my passcode in when I start my phone, it just turns off. It's been doing that a lot lately and been driving me insane. I have completely factory reset my phone numerous times and wiped out all my apps and everything.. but for some reason it still does it. I cracked it about 3 months ago, but it's been doing fine until now. So I really don't know. Can somebody help me?
