I recently had my phone stolen and would like to know if I should change all my debit cards and other sensitive info. I want to know if is it possible to actually bypass the default lock screen and password for Android on a Samsung Galaxy J7 Pro. I am running Android version 12 and do not have developer mode enabled.

Apps like iMyFone and LockWiper claim that they can do this. If so how? I thought, your data was encrypted if you use a password.

    The phone data is encrypted but the OS will automatically decrypt it once you have entered the lockscreen secret the first time after boot. And there was just recently a serious flaw found in the lockscreen which allows to bypass it: androidpolice.com/… (not sure if this also applies to our phone) BTW: Why do you store debit card info on your phone?

  • Without knowing how those apps work, we have a related tag locked-out for end-users who want to bypass/remove the lock screen. Combined with the 'lock-screens' tag, you might be interested in browsing them.

  • @Robert What if the lockscreen secret is not known to the attacker ? Is there any chance the attacker can access the data ?

  • @Robert How are you able to access the /data partition without decryption ? Look at this article. forum.xda-developers.com/t/…

  • As I wrote once you have entered the lock screen password the first time after boot all data can be decrypted until you reboot. So if there is a way to bypass lock screen without rebooting the data can be accessed decrypted. Such a way to bypass lock screen was described in the linked article of my first comment.
