The screen on my iPhone 4s is jumpy/slightly flickering. It's very slight and I don't see any horizontal lines or anything, but it's quite annoying. This just started today: last night my phone powered down because the battery ran out, but everything was running fine. Today, when I plugged it back in to charge and it powered back up, BAM, the screen was all weird.
I've had the 4s for about a year now, and I've had iOS 6.1.2 installed since it became available a while back, but like I said, this is the first time the problem has come up.
Anyone have any idea what could have caused / is causing this to happen? Has anyone else been experiencing anything like this?
