    I factory reset my Galaxy S5 as I will sell it to someone else. I have a lot of personal staff on it so i want to make sure all of them being deleted completed. After reset, I tested it with a free data recovery software and found out contacts and photos were still there.

    My question is: how to completely destroy those files?

    Set it up again (before you sell it) with your Google account info, then encrypt the phone (in the Security settings), don't add anything else to it and as soon as the encryption process is done delete the Google account so it shows no account info whatsoever on the device, then do a factory reset which will end up decrypting the storage during the process and wiping it clean.

    At least that's how the theory works to do it: encrypting it secures it but the factory reset has to decrypt the storage volume so that means a secure wipe of everything leaving it truly factory fresh.

    How much time it takes to encrypt the device? two hours passed, it is still in progress.

    I don't think the factory reset will completely wipe your Android data, it still be recoverable! There are many editors or expert confirm this point in CNET, or Androidpit.
