Hi @ilyasmiah, Often, removing the cache for some apps also helps in solving problems in my experience, and also removing and reinstalling updates like you're already doing. If that didn't work I'd restore the factory defaults and start over. Also make sure if you reset, that after that you set it up as a new device, without syncing apps and settings. I've had problems in the past where a launcher3 error kept popping up because somehow settings from a phone got synched with a tablet :S. I've never tried installing custom roms and such, so I cant tell you anything about that I'm afraid :).
