I have done exactly as written with previous data backup, of course. Initially, the lock screen "Drag to Unlock" there are yellow screenshots plus Google Maps also has screenshots yellow now (it was the first app that was then open the reset). In Riptide GP2 my driver like a ghost because I only see the silhouette of the chest and helmet. Must be a software problem because Google Chrome v39 Maps on my G2 is very fluid and no winks as the default app. Thank you very much anyway. XD
