Yes my fingerprint scanner has stopped working altogether after getting my motherboard replaced by lenovo authorised service center.when i approached them about it they fixed it temporarily for a week at the maximum but then again the fingerprint stopped working altogether.then i then got extremely angry about it ( cause the service center is too far from my house and i travel by bus).this is dissapointing at the least as an authorised service center does this to you .This was my first experience with lenovo authorised service center and it will be the last one.does anyone know how to fix this issue or should i have to change the existing fingerprint scanner.
Don't bother to change it. Some models, like mine, have this issue. The fingerprint itself is not broken, is temporarily not working. This time can vary from days to months. Mine is now not working since 1 month.
I do not rely on it anymore. I would say that this is the only back stain of this phone.
You can google it for yourself, unfortunately is quite a common issue.

The problem started after I got my motherboard changed and that too by official lenov guys.I am suffering without a fingerprint for almost 9 months and have to use password Everytime .
Found the fix to the problem .I just installed havoc os 3.1 28 the Jan update and voila fingerprint started working.man I'm so happy .all these days I was blaming Lenovo officials although it actually had stopped working after I got my motherboard changed.

I guess i got it fixed .I literally put sanitizer on my fingerprint scanner and voila it started working.Dont ask me why I used sanitizer,I just saw it lying on my desk(corona virus effect) and thought why not use it.try this once maybe it might work for you.you need to rub all over your fingerprint scanner.

My fingerprint was working fine. But started to give problem after software update. But after few days it started to work properly.
But now again it giving problem.
Have u got any info from service center where was the problem?
The rear camera on my one plus 3 sudedenly stopped focussing
It worked great but about a week back, it suddenly went bad. I've tried using manual focus but that doesn't work either.
It only works at times when I vigously shake it and then it goes bad again
Has anyone encountered this issue? Any fixes?
There are no proper service centres where I live.

Probably a result of the camera module becoming loose due to a fall (not necessarily recent). Search on XDA for this issue. I remember reading about atleast a couple of threads/posts about having solved this issue. You will have to open the back of the phone, locate the camera module and fix it. Or order a new module and replace the old one. Costwise it is not too high.
Replace your camera - this is ONLY permanent fix.
I done it on my OP3T and it works again.
Had exactly the same issue (resolved temporarily after vigorous shaking - it's a known issue and quite common) last year with my OnePlus 3. TL;DR: Definitely contact OnePlus and they'll replace the camera module for free assuming no other physical or water damage. I have in the past had mediocre experiences with OnePlus support, so was frankly astonished at the way and speed in which they handled this. Should have a year or two of life left in the phone now and certainly a new sense of brand loyalty for future purchases.
As for my experience:
- Problems started in around February.
- Finally contacted OnePlus support via official chat in late November, was asked to factory reset to see if that helped. Didn't help.
- (25/11) They fast tracked my RMA request, even though out of warranty.
- (27/11) Phone sent by courier from UK to Poland for repair (as with you, no service centres here)
- (28/11) Device repaired
- (29/11) Phone sent back to me
- (02/12) Phone received a week after being sent and camera working perfectly. Total cost to me £0.
Side note: Definitely get a Google Camera mod once your phone is fixed if you don't already have one. Breathes a new lease of life into the camera with some software smarts. I use this one: https://www.celsoazevedo.com/files/android/google-camera/f/changelog849/ as recommended by the XDA Google Camera Port Hub.
Replaced for free

They replaced it for free as it was a manufacturing defect even though warranty was over.
One year ago my oneplus 3 experienced a hard time when rear camera focusing. I was in china, so I called oneplus support and the guy one the phone told me that i can mail my phone to the services center in beijing and then they replace a new rear camera for free(even though the warranty are expired).
Replace the rear camera may be the only fix. Perhaps you can call the services number on oneplus website and ask for help
Hello. Since few days I've experienced some issues with my LG G7. Fingerprint scanner seems stop to work sometimes, sometimes it works fine. Doctor shows same results - sometimes "good" sometimes "wrong". Any chance to repair it by myself? Or I need to ask support center for help?

I've had the same issue. I know how frustrating it can be especially if like me you use it to unlock everything. All I can tell you is for me restarting the phone solves the problem. It eventually stops working again after a couple of months. A friend of mine has a G7 and hers did it too. Do not try and fix it yourself. Contact support. If you bought your phone new remember LG started offering 2 year warrenties with their phones so if you fall into that category take advantage of it and Contact LG. If that's not an option keep an eye out for open enrollment insurance. Insurance is normally something you have to get when buying the phone, but I know Sprint, T Mobile, and several MVNO's will offer open enrollment periods for about a month for existing customers. If by chance you get enrolled pay at least one bill then contact about the issue and insurance will cover it. I'm just sticking with the reboot fix for now. It's been 2 months and no problems.
i have same exact problem any solution without reboot you have found.
Nothing works to solve it for me now. Fingerprint unlock works about 10% of the time - always random.
LG hardware is garbage. Never again - 3 devices all failed or failing
I disabled all fingerprint login options for all apps that i installed from Google Play (Mobile Bank, PayPal app, App for paying with NFC, Mobile Operator App, etc.) and for now it works without problems.
Mine is Fixed.
Hi All,
I had the same issue where my phone would intermittently detect my fingerprints. This was painful & frustrating, to say the least.
For other issues with the phone, I had to format the phone, that seems to have done the trick. My phone now detects my fingerprint as it did before. I am not sure what the issue may have been but if you are really frustrated with the scanner not working, you may want to give this a shot.
Hi there,
A few days ago my fingerprint scanner just stopt working.
So does anyone know what is going on and if I can repare this problem easily?
*#*#64663#*#* use this code to test the fingerprint hardware.
Input it in the dial in the phone app.
I had the same issue for quite awhile, a factory reset seemed to have sorted the issue but it started to be hit and miss again not long after. I've replaced it with the X3 Pro now so don't know if it's returned full time.
Oh, maybe just take it in for repair and see what their opinion on it is.
Is actually very easy to replace the FP scanber in this device and AliExpress has the part for sale
Best get it repaired at an authorized dealer....
Unless getting fake stuff from aliexpress :/
Please help me to solve this issue.
Try this step again, Go to Settings > About Phone > All specs, tap kernel version many times, test fingerprint sensor. Visit the service center if the test fails or install android 11 new version.
I'm sure this is a software problem. I've never been this careful with a phone in my life and I also have the same problem. Unless the update somehow tucked with the motherboard idk. But my best option is to wait for another update to roll out

I bought this phone and after some months i faced this stupid issue too. I've been very careful but had to send the phone to a service center. They said that they changed the fingerptint sensor. Since then no more fingerprint issues...
Same thing with me, it was hardware. After only 6 months of use, I had to send it to a repair service under warranty. So far I had no issues with the sensor.
same here, fingerprint sensor is missing from menus. I will send it to a repair service.
Well it seems the only solution is to send to repair and i think warranty will cover that.. Seems like factory problem :/
But I don't care anymore, since if i send it, it would take maybe 1-2 months, so during that period i would be without phone..
Possible fingerprint sensor flex cable damage. Try restarting your phone while gently pressing around finger print sensor.
this is not a software issiue i have the same issiue and i changed the sensor 7 months later it still works great
I was also careful with my phone and after 3 months of buying it, the fingerprint unlock option disappeared. I couldn't find any solution and tried everything I could. In the end, I took it to a repair shop and they told me that the cable connecting the fingerprint sensor to the motherboard was damaged. They said it was due to a design flaw by Xiaomi. I would recommend you doing the same thing if the rest of things dont work.
The same problem started for me. I had used it very carefully until this time. As you mentioned, it seems to be a chronic problem. When I did some research, many people mentioned that it was fixed with a software update. My sensor disappeared a few days after the last security patch. It could be a coincidence, of course. For now, I am waiting for the upcoming MIUI 14 update instead of sending it to any service. I hope it solves the problem or I will probably send it to the service.

Unfortunaly its hardware problem bro. Button needs replacement , and there is no guarantee how much time will work even replaced. I hate to send to official repair shop, as it will takes weeks, and i have no spare phone. So i just use double tap to turn on the screen aswell to turn off the screen on display
