Sometime in the last week, my rotation, proximity, light, and orientation sensors all stopped working. Everything worked fine before, but just stopped. I'm not sure exactly when. All the remotely similar problems here had solutions which didn't apply to me.
It's an LG K8 V purchased almost 2 years ago. VS500. Hardware version says 1.0. Android version is 7.0, software update says "20i".
When I rotate the phone, no apps rotate. I checked and changed the quick rotation setting, and all the rotation settings in settings.
My compass shows no needle and is stuck at 0 degrees.
When I hold the phone to my head, the screen does not turn off.
With "auto-brightness" turned on, the brightness doesn't automatically change.
I have a sensors monitor, and all the sensors say "Waiting for sensor to become ready." It worked before.
I've tried the online troubleshooter, but nothing applied or helped. I've restarted. I've powered off and left if off a few minutes. I tried starting in safemode, but it didn't work there either. I didn't see anything unusual when searching logcat for "sensor", but there's too much data and I don't know what else to search for.
