hello Lifegamer,
It looks like a broken screen but it doesn't have to be. Similar behavior will show a screen where someone was working on SIP and did the job wrong. If the phone is new, the manufacturer's warranty is still valid. Take advantage of it. If used one and you just bought it (you don't write anything about the origin of the phone, which is important from a diagnostic point of view) expect a screen problem. The last thing on my mind is a system crash. Model 13 is relatively young and most of the so-called permanent faults have not yet been discovered. If it's one of them, maybe a system restore will help.
