Thanks for the suggestion. I recently uninstalled a lot of stuff I don't use, but there's still a fair amount of stuff on it. I have set a couple apps to not run in the background - is there a way to set something like the sensor program to not ever swap out? I did a test - the last two times it had the problem I put my finger on the sensor, waited a second, then removed it. I didn't touch anything else (buttons, screen, etc)... I just waited. Both times, after 5-10 seconds the screen unlocked. So it does feel a bit like a swap problem, except some process is successfully reading my finger - it's just not telling the phone to unlock. It feels very much like the volume control problem I mentioned too. These are vital system functions and should NEVER be swapped out, or put to sleep, or whatever is happening. The good thing is that the problem doesn't happen every time, and rebooting never seems to be necessary for me. because once it' sunlocked, I don't see the problem again for half a day usually. It's probably because I have it stay unlocked when my bluetooth is connected, so I only have to use the fingerprint maybe 1 in 10 times I unlock it.

I'm having a similar problem that I can't find a record of anyone else having quite the same as mine. Randomly I will wake the phone to unlock it and then put my finger on the scanner, but it won't detect anything, so it goes back to sleep. But if I try it enough times, or maybe just wait a minute, it will start working. I've had the phone for maybe 4 months and this problem literally just started a few weeks ago. I've rebooted a few times since it started but it hasn't gone away. I don't know if it's related, but I also have this problem where randomly the volume button will be unresponsive. I'll be listening to a podcast and the screen will go to sleep as usual. Then randomly I'll try to adjust the volume and nothing will happen. I'll move it up and down a couple times with no result. Then, 10 second later, the volume popup appears and the slider moves rapidly up and down as if it were finally executing all the adjustments I did. It seems like both of these things are the phone briefly locking up. But audio keeps playing, the power button wakes up the screen, etc. Anyone else seeing this?
