Galaxy Tab won't unlock

Anche io ho questo problema

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.

Model is SM-T830

 

No error messages initially. After trying numerous things off/on for nearly an hour last night (WiFi, Bluetooth, Daily Board etc.) I started to get "System UI has stopped" every time I entered my PIN. My guess is that it was the error all along but it just wasn't getting displayed as the screen usually went black right after entering my PIN.

 

In the end I found out I could reboot by holding down Power + Volume Down and thankfully it has started up fine this morning.

Can you try logging into your Samsung Account and use the options in that to unlock your device if that's possible.

 

Or visit a Samsung Experience Store or Samsung Service Centre.

 

 


Daily Driver > Samsung Galaxy s²⁵ Ultra 512Gb ~ Titanium Black.

The advice I offer is my own and does not represent Samsung’s position.
I'm here to help. " This is the way. "

@RobinElvin: Please can you confirm the model number of your tablet? Are you getting any error messages when you enter your PIN?

Thanks so much for this post. I left my Galaxy Tab S4 on charge while spending over a week in hospital. The exact same thing happened. Power + Volume down to reboot my tablet without losing any info on it.  So thanks again for this valuable info!

Tried this solution on my SM-T835 and it worked. Had taken tablet to Samsung shop and they said that it would need to go back to their workshop for a "Factory Reset"

Big  many Thanks

The Power + Volume Down solution worked for me, too, on my Samsung Galaxy Tab A. Seems to be a common problem, so I'm glad I found your solution.
