A week ago Friday my phone started rebooting. I got the phone week after the Droid was released and it was fine until last weekend. If I was using any apps it was ok but if I hit the power/"screen lock" button it would reboot. If was on the desktop and it timed out it would reboot instead of locking the screen. 100% of the time if I tried to play a YouTube video the screen would come up the loading icon would do a 3/4 revolution and then the screen would lock. Trying to replay videos I took, using the camera, also rebooted the phone. After a few seconds of this it would reboot again. The only way to power down and stop the reboot cycle was to pull the battery but if I fired up the phone I was back to the reboot cycle again. 15 seconds of a phone call was the best I could do before it would reboot too. I uninstalled recent apps, called Verizon and did a factory reset. It took 3 attempts but we finally got to reprogram the phone by dialing *228 with the tech on the other end of the land line. This got me to the Android icon, to set up my phone, but every time I pushed it the phone rebooted. I brought it to a nearby store and upon seeing the same they promptly replaced my phone. My wallpaper and almost all the apps I had downloaded were still there so they must have been stored on the SD card. I had to resynch Gmail and redownload a couple of missing apps. Aside from the recreating my desktop layouts I was back up and running in minutes...pretty painless. Even my wireless passwords were saved....which freaked me at at firstI know my brother isn't BSing me about getting an OTA update, but as I said, his ESD is still 56. His phone came with 2.01 on it, so it couldn't have been that update.
Whatever he did get seems to have totally broken his YouTube app and any viewing of YouTube all-together.
Anyways...seeing your post on videos being unplayable prompted me to post this. Neither I nor Verizon knows what caused my phone to fail. I also never rooted but did manually apply the Dec update. All is well now that I have my "like-new certified" replacement phone.
