Fingerprint unlock and settings menu not working - HTC 10 Questions & Answers

Hello everyone,
for the last few days I have been unable to unlock my phone with the fingerprint scanner and had to use the code unlock. The hardware part apparently still works, since the "wake screen with fingerprint sensor tap" still works, but I can't even remove old fingerprints, or reset the scanner settings/data.
I'm using everything stock on 3.16.401.2 firmware.
It doesn't even work in safe mode (I've read that it may be caused by a third-party app).
Has anyone come across this issue, or a similar one?
I'm guessing factory reset could probably solve the issue if it is solely software related, but I'd like to solve it without that.

Do you use custom recovery (TWRP) or still Pure Stock? I have a solution but must be in custom recovery or rooted device.

Unfortunately it's all stock. After talking with HTC support and clearing Fingerprint scanner cache and data, the problem of not being able to remove scanned fingerprints still persisted, so it looks like I'll have to factory reset.

Gyroscope and other sensors not working after recent updates. HELP!

Thank you for clicking on the thread.
I've loved my Zenfone 2 for a while now. I have the 64gb 1080p model. It was a well priced powerful phone for what I wanted.
However, I recently received an asus software update that completely borked the Gyroscope and some other sensors. I have read about similar issues online and testing the sensors reveals that they're not working.
Does anyone know how I can fix this? I have been unsuccessful in trying to install CyanogenMod13 or even TWRP/CWM. I rooted my phone and the bootloader is unlocked (white backscreen upon loading).
It seems as though ASUS doesn't want to fix this, would upgrading to a custom ROM provide firmware that would properly recognize and use the gyroscope as input?
I've tried wiping the system cache in the stock recovery, resetting to factory new and everything to no avail.
I am willing to "tip" or "pay" for someone's time if they can help me as I cannot auto-rotate or use any applications requiring certain sensors.
Thanks for your time.
I've upgraded to CM13 successfully now and the gyroscope is still not even recognized in Sensor applications. Is it hardware?
solution?

Fingerprint scanner problem

Ever since the latest Android update (see picture for my phone stats) my fingerprint scanner has stopped working and every relevant menu has dissapeared. Does anyone know how to fix this?

After a factory reset it worked for a day after the phone couldn't find it again. What should I do D: ?

Fingerprint scanner stopped working

Just recently my fingerprint scanner will decide to stop working. I'll dirty flash my ROM (latest PureNexus) and it'll go back to normal for a little while. Is this a known issue with nougat I'm not aware of?

No, that is not a nougat issue or an issue with that particular rom. It's either firmware, which is in vendor our a failing fingerprint sensor. Try re flashing vendor and see if that helps
I was having that problem too. I tried several things with no luck. The menu option for the fingerprints (under personal/security) disappeared, and since I am clueless about the Nexus phone (iPhone convert), I was baffled. For a separate reason, I had used the ad blocker plus browser to clear the cache of suspicious garbage, then restarted my phone. The fingerprint menu item reappeared, and now the sensor works again....so try clearing your cache.
I got too i fixed by clean fingerprint connector in the phone.

Sensor issues after installing and wiping "o" beta.

So I installed the beta and decided to go back to 7.1.2.
I did a normal wipe in TWRP then reinstalled SAOSP.
The first problem I noticed was that the phone was slow to turn the screen on after pressing the power button or the fingerprint scanner.
The second problem was that the proximity sensor wasn't working in phone calls. I then checked a few others sensors and noticed that the rotation also want working.
I downloaded a sensor checking app and it showed that the proximity sensor had a value of 5 but it didn't change when covering the sensor.
First thought was a bad flash, so I re-wiped and installed a Nand backup that I knew was good. Same thing happened, so I tried PN. That didn't work.
Downloaded stock zip, backed up personal data, then did a complete wipe with the zip, internal data included. The problems stayed even on stock.
I have since read through whatever threads I could. This seems to be a random issue people have had in the past. Yet is particularly prevalent after the o beta.
Most people have suggested to just re-flash stock but that hasn't worked. The only suggestion I have read otherwise is to also lock and then unlock the bootloader in the process as well.
Who else has this problem and has anyone found a fix yet?
Ok, someone posted in another thread (PN) that the locking and unlocking the bootloader worked for them.
If you have the issue try it out.
Just remember to copy all your internal data to your PC or other storage to save it.

To fix this, I flashed O DP2 factory image again and then stock 7.1.2 factory image. Now everything's working and I'm rocking Dirty Unicorns 7.1.2

I tried it this way but after flashing back to 7.1.2 stock, I now get a crash of com.android.phone immediately after booting, followed by a reboot.
Tried clearing cache but didn't help. Anyone know what to try to fix the crash?
UPDATE: Wiped data and now it's fine.

Face unlock data disappearing

For some reason my face unlock data keeps disappearing. Anyone know what may be causing it? This is the second time I've had to add my face data again.
Edit: I've tried formatting, resetting, etc. Just wondering if anyone else is having this issue.
Reset the device
Go to the bootloader and factory reset.
Disclaimer: you will lose all your data.
I've tried that already. I'm currently using the stock rom with simplegx and magisk.
It happened to me this morning. As soon as I turned on my device, face unlock was not working anymore and I found it had deleted my face data. Having my 5T for the last 2 days. Hope it won't happen again.
How frequent did it happen to you? Are you on 4.7.6?
Its happening to me too. I have my 5T for one week now and I already re-scanned 3 times. Don't know what's causing it. If I find a correlated setting or tweak (Magisk, Xposed, Amplify,...) I'll post it here. Are you guys rooted?
