Hi, I have two andriod phones that I need to be able to wipe clean, ie: personal data, account log in details, pictures of my daughter. I have a Samsung Galaxy S4 & S3, both have broken screens. The S3 I have no idea what is wrong with the screen, it just went black and has stayed that way. I believe the screen is still responsive as I can hear the water sound when I swipe the screen. The S4 I believe the LCD has broken. Again, the screen is completely black. I dropped this phone as so it has a crack in the top right hand corner. Unable to hear any sounds when I swipe etc on the screen. I have tried connecting the phones to the computer via usb and use Samsung Kies, the S3 connects but it says there is no pictures etc on the phone when I know there is. The S4 just doesn't connect at all. Also tried programs like MyMobiler and MoboRobo with no luck. I believe the phones aren't debugged Also if I have signed into my Google Account on another Andriod device would I still be signed in on the S3 & S4? any help would be greatly appreciated.
