Hello all, Not here to complain, but to figure out something. This is not my first phone or my first Apple product, but I started seeing glitches that were previously not there. I was totally happy with the iPhone 5s and IOS 7 when it was at the end of its cycle. First of, yesterday my phone started vibrating as if somebody was calling me. Tgere was no call notification, but the vibration kept going. When it stopes, I got a notification of a missed call. Second, I just cannot answer a single Viber call. When my screen is locked and I see somebody calling me, I slide to the left and see this (picture). Other things like a funky looking front page.
