So I had a Droid Pro, but I dropped it and the internal screen is now broken. So I can't see what's on the screen. But the touch screen works and I can unlock it and call people because it's not very hard to guess where the buttons are located on the screen. It's difficult nonetheless, but eh. Anyways. A friend of mine is offering to buy it from me, but the only problem is, I want to wipe the phone clean before I give it to him, because it has personal messages on it and I'd rather him not read those. But being as how I can't see the screen, I don't know how to return it to factory settings. And being as how I've never had to do this before, there's no way I can just guess where that option is located on the screen. Does anyone have a solution? It would be greatly appreciated!
