Hy Guys!
I have a problem with my vodafone smart 2 phone. My device is running CM7-B2. The gyrosensor just stops working at random time and doesn't work again until I install the original ROM (and then I install CyanogenMod again). After that my phone works perfectly sometimes for month but now for some hours and without any sign the screen doesn't rotate again. Nothing else breaks only the gyrosensor.
Do you have any idea what may be the problem?
Thank for your help!!
If the sensor works fine on Stock firmware then the CM Kernel is lacking correct drivers. You may want to contact the developer of the Rom or post in that thread. You could also try another Rom such a Albert96 Rom
You can Try Protractor or Bubble Level app to calibrate the Sensor. If either app has a limited success, you may have a hardware issue.
As my colleague suggested, you may also try *#0*# on your dialer and then use the Sensor test to see if everything is operating correctly.
Hello, i saw some video of lineage os 15.1 and in that the guy would switch his phone on by just gently keeping his finger on the fingerprint scanner, like most phone's. Is there anyway around it? I physically don't wish to press the button. I also feel the finger print isn't accurate always. I've added multi finger prints. I'm using stock right now and I plan to keep it that way, no root.
The only way to do that is to install superman rom. Selecting the modified system ui in superman rom allows us to enable always on fp sensor ?
Hey all,
I experience problems with the fingerprint sensor. It often doesn't recognize my finger on the first try but I need to try it several times before my finger is recognized. Or face unlock solves the issue and thus the finger print problem is avoided. I also deleted the finger print and set it up new several times but the problem persists.
Anybody else got the same problem?

Nope, my fingerprint sensor works perfectly fine.
Yours may be defective.
Take off the case from the phone. Make sure u scan ur finger correct.
If is not helping factory reset.
If is not helping call oneplus...open return due defective hardware
This finger print sensor reads much differently than what I am used to. For me it's literally a quick tap with my finger. If I hold like I would with Nexus 6p it won't read.

The sensor is really quite small and not perfect. I scanned the same finger three times (different parts of the tip) and now it works quite well. You will get occasional errors stating that the same finger has been scanned already, but if you keep trying it works
It's not a perfect sensor or even close, I've had to add a finger twice to get it to unlock properly most of the time. I add it as a new finger.

I bought the OnePlus 6 and I came from the OnePlus 3 and I ran into a similar issue. It helps if you input your fingerprint multiple times
For me its not that it doesn't recognize the finger, but sometimes it just doesn't even recognize that I have placed my finger on the sensor to check if it's mine. I have no idea why this happens
Mine works great. Sometimes I think it's even too sensitive, I turn the phone off and it comes back on when my finger is still in the vicinity of the sensor. Try to wipe it off with some mild water-dishwasher solution to get any dust/body oils off of it.

Are you running a custom kernel? I had this issue on Stock OS using Flash Kernel. Reflashing back to stock fixed it for me
My fingerprint recognition was always failing. The sensor was working because it would vibrate whenever I put my finger on the sensor but it never recognized it. I contacted OnePlus Support and the first thing they recommended is to see if there was an upgrade available. There was one - so I upgraded - not really thinking it would help at all. But miraculously, after the upgrade, fingerprint recognition works like a champ.
Try upgrading.

For me I had this same issue but not initially. The first 4 days I ran into zero issues. It worked every time. I then decided to start tinkering and installed the XXX mod. It wasn't quite what I was looking for so I decided to return to stock. At this point I flashed the stock rom via phone update menu. Then I factory reset and set up again. I noticed memory management issues and also problems with my fingerprint reader not recognizing my finger as easily. Re doing them didn't help. So I thought maybe I would use the fastboot method of restoring the software like the Nexus/Pixel roms. I did that and it flashed successfully but had the same issues. So I decided to manually flash each partition on both slots. Then I set up again. Still had issues. I figured at this point it was definitely a hardware issue because I felt I couldn't be any closer to a stock, out of the factory condition. But I was wrong. The msm tool that uses the Qualcomm drivers is the "Factory Image" I was looking for. It completely restored my phone to the condition it was when I unboxed it. I know logically there shouldn't be a difference but it flashed or fixed something on a certain partition that got changed when I was tinkering(I assume). So long story short. Try the msm tool if you think you have hardware issues before you rule out the software.
Fix-Fingerprint sensor not responsive
Entered to safe mode fixed the issue for me after a lot of trying to make it responsive.
Go into battery /battery optimization /hit the... Menu (advanced optimization) uncheck advanced optimization.
If on she is saving battery in sleep mode.
The issue you guys are describing is simular on rear sensors.
I did the above and it helped. Give it a try.
Hey guys, I've been playing with the phones setup for a few days now figuring everything out and how it works, and I noticed the left fingerprint sensor isn't half as sensitive as the right one. Anybody else notice this?
I've tried setting up the sensors to be back on the left sensor and home on the right one and the home works perfectly, but the back on the left works only 10% of the time. (I am left handed so I try to use the thumb/left for back).. A software update will fix this I'm sure (If it IS software related, and not a faulty phone I have.)
I think I have this set up in the wrong section??? Moderators could you move it please if it is. Thanks!

Actually, my fp scanner are perfectly fast (and equal).
Try to remove both configurations or reset the firmware - it might be a hardware issue that requires you to send it back!
Cheers
I've just replaced the screen on my friends S5 Pro and currently don't have a working FP sensor. I've double checked and the sensor is seated correctly and there is nothing obscuring its little window on the screen.
I want to recalibrate the sensor, but cannot find a way to do this. All of the useful dialer hidden codes are disabled. It might be that doing a factory reset or re-flashing the full firmware would trigger the sensor to calibrate itself, however my friend spent days getting everything just how he likes things and says he'd rather live without the sensor than have to set everything up again and doesn't trust non-root backup solutions to work properly. He doesn't want to unlock his bootloader, so rooting is out of the question.
Does anyone know of any way to get into some kind of engineering mode on this phone to be able to force a fingerprint sensor calibration?

The fingerprint sensor went completely over the cuckoo's nest in my Umidigi S5 Pro for no apparent reason, now I can't use it at all. Any ideas?
Same thing happened to me shortly after an OTA update if I remember correctly... any luck with a fix thus far?
