Hi all, I've purchased an Acer Iconia A3-A10-L614 tablet running Android 4.2.2 stock. I can't seem to make the "vibrate on touch" to stay off after reboot. If I turn it off by unchecking the box in Settings>Sound>Vibrate on touch it works until the next reboot. Looking in the same menu, it's selected again. As a side note, same thing happens with the screen lock sound (but since I choose to have no screen lock it doesn't affect me). I've done a full factory reset which didn't change anything since the tablet is brand new. A friend of mine bought the same tablet from a different store and he has the exact problem. Can anyone help? Thanks in advance!
