I was gifted a secondhand Samsung Galaxy Series A80 by an online vendor, but little did I know that the device is T-Mobile SIM locked and screen locked. I chose to factory reset the device to remove the screen lock but landed on the horrific ‘Google Account Verification' page. Now, I'm caught between returning the phone to the vendor or finding a potent Android application that can unlock the aforementioned three locks. Is there any Android unlock app that can unlock screen, SIM, and FRP locks from the Android device?
