I bought the ASUS memopad HD7, ran through initial setup fine (4.2.2), modified the settings somewhat then started to disable some annoying Google automated app update systems (still bugs me that i cant tell the pad to ask me whether i want to update or not so have to modify the apps' settings individually). Through settings i enabled 'unknown sources' to download Flash for android, bypassing the Playstore (although now i'm just using the Youtube app which works fine HTML5). After the download and putting the tablet off i switched it back on, but the SETTINGS button crashes and i cannot get it back. I would think that Settings wouldnt be possible to block being in the..well..system. So security wise i'm wide open. Any idea to fix this?
