How to make sure that everything is deleted without physically seeing it on the phone

[bilatrick]

Hi, not sure if i am posting this in the right place

I want to get rid of my S3 since i upgraded to a S4

My S3's LCD is broken so the screen won't turn on and i want to sell it for parts

but how can i make sure that all the phone numbers are deleted on the phone even after a factory rest ?? Since i am not able to see what is in the phone because the screen cannot turn on lol

Thanks in advance !

If your S3 is still connected to the internet you can use the free app AndroidLost to wipe it wirelessly/remotely.
