Okay, so I've had my iPhone for About 1 year now, and it was absolutely great and amazing until recently, I dropped my phone once for the first time about three weeks ago, it was still working fine but there were cracks everywhere, nothing internal thank god. And last weekend I got it fixed, but for about 3-4 days now when I open apps, or get on FaceTime or make a call, my iPhone has been messing up, when I open apps after about, 3 hours of using my phone, like constantly, out of no where you will begin to see apps that were recently opened in the back ground of an app that is already open even if I clear my recent apps my screen is faded but still works and I can see apps or anything opened in the back ground, and when I factory restart my phone by holding the power and home button it usually works, but last night while it was restarting you could see my recent apps behind the apple logo while it was restarting! It's like a vague image of messages or FaceTime or what ever I have opened last, and IIm scared this problem could be serious! My iPhone is still usable but IIm not sure what to do!
