I've got a Galaxy Tab 2 7 inch that our dog decided looked like a treat. He started to chew the lower left corner until the screen broke. Unit will power on but all we get are some blue lines across the screen that will change when we tap the screen but still can't make anything out. I want to sell this thing to anyone who knows how to change the screen out and may then want to sell for a profit. I'm not capable of doing this myself and screen replacement is cost prohibitive for me to pay someone to do it (already bought another anyway). My question is: Can I erase any information of a personal nature that may be on this tablet? If so , how do I go about it? Thanks in advance.
