Locked Samsung tablet A My grandson has put a pattern lock on his tablet &amp; has forgotten it. When I try to turn it off or sign in I keep being asked for the pattern I’m just locked out
You might keep trying patterns if you think that after a number of wrong patterns you could get right one but android will setup a timer to wait if wrong pattern is drawn and each time timer to wait will increase.
The next option would be a hard reset your device.
Please keep in mind

• Resetting your device will completely erase all user data on the device.
• After reset you may be asked to sign in with the previous Google account (as a security feature named FRP) that the device had previously signed in before Resetting. So, make sure you have sign in detials of that account.
