I have a flawless iPhone 5 that works perfectly. However, on the App Store and the iTunes Store when it asks for my password, I will go to type it in and when I do I will see these lines going across my keyboard that move and act like static. I ordered it from apple so my question is, should I return it? Or is this a software issue? It doesn't do this anywhere else on the phone. It only happens when the keyboard turns black and asks for a password for one of the main stores. I was able to make this happen purposely several times on my phone, but when I grabbed my husband's iPhone 5 I could not mimic my problem. I am including a video I found on YouTube that mimics the same problem. http://m.youtube.com/#/watch?v=BJobxmLXiHo&desktop_uri=/watch?v=BJobxmLXiHo Can this issue be recreated on an iPhone 4S or anther 5? Not sure what to do.
