I am unable to get into my tablet after leaving it on charge. The unlock requires a PIN and biometrics are unavailable until next time. I enter my PIN and it just takes me back to the lock screen. It looks like the PIN unlock is crashing.
Because the PIN unlock doesn't work I can't reboot or shut down either.
How can I get around this? The battery is at 100% so it'll be over week before it runs out.
Solved! Go to Solution.

If all else fails, you can use the recovery menu to wipe cache partition. Access method varies with model.

For people have trouble with the Power Button + Volume Down method, make sure you hold it down for about 10-15 seconds before trying again or finding other methods. I thought it didn't work for me until I found someone from another forum briefly mentioning it. Even if your tablet takes a screenshot or the screen auto shuts off due to inactivity, KEEP HOLDING IT. I really hope this helps. I understand how frustrating and scary this situation might be.

Thanks so much, same thing happened to my son's tablet, tried unlocking through the Samsung account, could not, then I read this post and used the power and volume down to force a restart. After that, I entered the PIN and it allowed me in the tablet. Thanks again. MY son was going nuts.

This keeps happing with one of our two Tab A's (both appear to be on the same software versions) and has been happening for about 2-3 months. Power + volume down works to clear the problem but give it a few weeks and you can bet it'll do it again.
Lots of people are reporting this issue, come on Samsung isn't it about time you responded?

Thank you very much. The same happened with my Samsung Galaxy Tab-A. Thank God, I found this.

But Pressing Power and Volume down it again asks for the PIN and even though again putting the correct pin and it asks the same to wait for 30 seconds again and again. Doesn't work for me!
