In an event that you lost your phone, anybody who could actually do the master reset to gain access to the device and use it. The reset will, of course, delete all your files and data but they’re not important to other people, aren’t they?

  1. I recently purchased galaxy s8 phone.
    My shopping app requires a scanner.
    The scanner only scans two to three items at a time before you have to back all the way out of the app and rescan. Which is frustrating when you have several items to scan.
    Do you have the solution

  2. My secure folder on galaxy s8 is locked and It is now saying” Unauthorised software is installed on your phone. Secure folder has been locked to prevent unauthorised access. How do I fix this so I can access my secure folder?

  3. Can the thief do this?

    1. Wait for the phone to run out of battery.
    2. Charge the phone, then boot it to download.
    3. Coonect to PC, run odin and install stock firmware.
    4. walla! “new” phone.

  4. I just had a weird problem with my S8. When I got it 2 weeks ago, I set it up so that it could be unlocked with both a pin and a fingerprint. I also set it to stay unlocked at home, plus in my car when connected to the car audio system via bluetooth. Then I set the smart lock so that the phone is locked instantly with the power key, or 2 minutes after the screen shuts off.

    This has worked fine for 2 weeks. Today I noticed that the phone quit prompting me for a pin or fingerprint after I had supposedly locked it with the power key. It didn’t lock automatically 2 minutes after the screen went dark either. I was miles from my house and not near my car, so it should have been locked. I double-checked the settings and nothing had been changed. I was able to fix the problem with a simple restart, but I don’t feel very confident about the locking feature if it can get disabled without warning.
