Well about 4 days ago my Motor Droid took a dive.
Went to YouTube and watched a video backed out of YouTube and bam, Droid went crazy started flickering, would start typing text on it's own, switching screens, no tap response. Pulled bat, did hard reset would work for a few seconds then start again.
VZ store did order me a replacement, got the replacement and it has the loose lower left screen problem, so VZ ordered me another one.
Can't say what caused the first problem but phone was in bad shape.
