A1000 opens menus/settings/apps random all by itself
So i have this Lenovo A1000 tablet for about 6 months. A few days ago started acting weird, opens launcher, menu, settings, options, apps randomly. I did a factory reset / format and still the same. It cant be stopped. Even after turn OFF and then ON acts the same. There is no virus, because i had a security solution for all this months, and now i tried some other apps to scan and still nothing.
I am the only one here with this crazy tablet ?
