Hello, guys. I am selling my phone with Android and I am looking for a way how to ERASE everything without a chance for recovery (without hammering ). I came across several articles that states we should encrypt the phone and then wipe it. I already got my phone encrypted but I found out that avast! Anti-Theft has a feature that can overwrite the phone. Should I normally wipe my encrypted phone with Android built-in feature or should I use avast! feature instead of that built-it in Android? What procedure would you recommend?
