Does ccleaner also wipes deleted files on my internal memory? Encrypting would be good but still i want it to be more secured before selling my phone
Wiping doesn't work on a flash based memory. When you encrypt it and then factory reflash, without your decrypt key or google user/password your device's former information doesn't exist. Flash memory stores data differently than hard drives (what we have in (older) PCs) and the data isn't as readily retrievable.
Ok thanks for clearing that out
