I'm running 4.2. Today a large section my apps seemingly uninstalled themselves, the blank default icon remains on my home screen, but the actual apps are uninstalled. I tried reinstalling from the market, but the phone reboots when it begins to install. I tried restoring one app at a time, and multiple from TB, but phone still reboots as it starts. I even restored a nandroid backup, same apps were still uninstalled and unable to be restored. Is this the beginning of my sd card failing?
