Hi guys,

I have a big issue with my Samsung Galaxy A21s. I set up a password for the lock screen a couple of days ago. Everything was working fine, but yesterday my phone randomly decided to lock itself for 1440 minutes (24 hours) after typing in my correct password once. I waited those 24 hours and tried again and it got locked for another day again. The password is 100% correct.

Or course I tried restarting the phone and booting it in safe mode, without success. I tried unlocking it on my computer via Google find my phone (I don't have a samsung account set up), but it appeared as offline, even though it is connected to wifi. I have to mention that it has airplane mode on which I can't turn off and NordVPN is installed. The phone has very few apps installed, such as Telegram, NordVPN and Instagram, no malicious third party applications...

I don't want to hardware reset the phone because it has very important things on it. Sending it to Samsung isn't possible as well, I don't have a bill for the product.

Please help
 
Regardless of what you do, you're going to need that correct password to fix things.
There are no work arounds.

once again... the password is 100% correct. It worked till yesterday and I got an immediate lock for 24 hours, not 30 seconds.
 
Was it new when you got it, or did it have a previous account.
With no data/wifi connection and no sim connection in Airplane mode, setting up a new password with Google (which also takes 24 hours plus to use) won't work either.

Only a factory reset in Recovery Mode will recover the device itself.
