After a Nexus 7 upgrade was interrupted, I restarted the tablet and a message said an application has crashed and I reported it (several times). The data shown for the report indicated that it was the Easy Video Player app that crashed - so I "uninstalled" that app. The message no longer appears BUT the icon to reach "Settings" no longer appears on a downswipe, AND the tablet goes to sleep after 8 seconds of inactivity. HELP!!!
