Thanks Upstate1618 I will try that next time it lets me enter another PIN which will be about 30 hours. I hope the problem is this UI bug you mentioned. That makes more sense than me forgetting my PIN.

The throttling times don't max out at 24 hours. I'm now up to over 133,000 seconds which is 36 hours between attempts.

de0u In theory the secure element (which is hardware) might have failed. This is genuinely quite unlikely, but in theory it can happen, just as any piece of hardware can fail.

If it's hardware failure and I bought a new phone, is it possible to somehow clone the image of the locked phone (in its encrypted state) onto the new one and try to unlock using the PIN? It's too hard to believe that I am forgetting the same PIN I've been entering for over a year. I wish grapheneos didn't have such a crazy upper limit on its attempt timer.

I read through the link but it doesn't mention if like stock android, the timer will go away after a certain period of idle time, or if there will be a timer on there between single unlock attempts forever now.

Another question I have is if I reboot the phone, it doesn't show the "wait 3 million seconds before trying again.." message until I try and enter a PIN. I am wondering is that first PIN entry attempt after restart a real attempt (it would unlock the phone if it were my real PIN) or if it's automatically rejected because of the timer which just doesn't show up until after I make one attempt?

Device: Pixel 7a
OS: Latest stable channel GrapheneOS
Steps to reprodue: In Settings > Display > Screen timeout, I tried changing the timeout from one value to another. This brings up a PIN entry. I typed in the wrong PIN too many times in a hurry and my phone locked me out.

Now I am unable to unlock my phone even though I am certain I am entering the correct PIN which I have no changed for over a year. The problem is that each time I try to unlock, the lockout timer increases and never resets, even when I don't make any attempts for 24 hours. The timer is now at 40,000 seconds! I don't believe stock Android's PIN entry delay goes that high. Is this limitless timer a GrapheneOS feature?

My questions are:

1) What could have happened? Why is the PIN I always use not working to unlock the phone after I wait for the phone to allow me to make another unlock attempt?

2) How long must I leave the phone untouched before the single attempt it gives me goes away and I am able to make several consecutive PIN attempts again?

3) Is there any upper limit on this timer? I thought 14000 seconds was excessive, now it's 40000 and keeps going up. I have data since my last backup that I really need on the phone. I can't factory reset it.

Thank you.
