I've been searching around for a way to edit out the extra nav buttons on the polaroid A/S7 (terrible tablet, dont waste your money). It has a vol +/- and screenshot button that i dont like. I cant find any clear cut method on removal for them. I was able to find a rooted rom for it so i can tinker with the insides. Also if anyone knows a way to make this thing less crappy please let me know! its prone to freezing and lag more than anything ive ever owned.
