Fingerprint Reader Issue when Charging

I know that a lot of people have had issues with the finger print scanner and home button, but I didn't see this mentioned anywhere.
When my phone is charging, the fingerprint reader doesn't read my fingerprint properly. It can tell that I have a finger on the scanner, but returns "Try again" and then fails. Is this an issue others are having, or should could it be an issue with the USB-C cable I purchased?
Thanks in advance.

I don't have this issue and my OP2 is currently charging using the official cable.

I faced this issue sometimes, failing to identify a pattern when it works and when it doesn't

Let's hope it's a software issue and not an issue with the hardware.

it's 99.99% hardware
I've just been through a remote session, where tech-support reflashed oxygenOS. I am suffering from the home-button not responding well when you grab the metal frame with one hand and touch the home-button with the other. In one hand it works fine....people call it a "grounding issue"---- however this problem is hardware related and pissing me off!
RMA .... here I come!

Turns out it's only high powered chargers that are causing an issue. The Anker 2.5A charger causes the device to not recognize fingerprints, while other chargers are fine.

With the RMA, they send you new device right?
Also what did they do during the session. They wanted to do the same for me, but I didn't want to give them access to my home PC.

They flash your device to factory state with oxygen OS 2.0.2
You can follow every step and abort at any time you want.
I think it's a standard procedure before the will grant RMA...hello bureaucracy!

I had faced this issue. Called up customer care they asked me to delete data and wipe cache using following way
Shut down phone
Press volume down and power key for few seconds
Choose wipe data and cache
Reboot
This will delete all ur data.
I did this yesterday and since then have not faced this issue whils charging. Lets see if this fix works.

Home button

Anyone replaced home button (fingerprint scanner)... My button is dead and in ebay you can order one for 9.99$ ...

Are you sure that the button is actually dead? I've read of a lot of people having the issue whereby the home button stops responding, and I've actually had it happen on my OPT twice myself and it's not been the hardware...
Two quick things to try (if you haven't already)
1) Try a force reboot of your phone (fixed my issue the first time it happened to me) - by this I mean press and hold the power button for ages, until the phone eventually just powers off immediately (without going through the shutdown process) and then power the phone back on.
2) Not sure if you have rooted your phone, or have a custom recovery (TRWP) but if so try wiping the Cache (not the Dalvic / Art Cache, but the other Cache) and reboot (fixed my issue the second time it happened to me).
Hope this helps.

If you have followed all the software solutions, still under warranty then RMA.
I faced this issue once, fixed it pushing around the sensor with my finger nail I did push really hard until it change to home screen it was 6 or 8 week's ago, haven't failed since

None of above have worked for me. I've a rooted A2005 running unofficial CM 13. A couple of days back it just stopped working. I thought it's a bug in the ROM. Changing and clean flashing the ROMs didn't fix the issue. Then I realized it's something serious as I remembered that it may have got some moisture when it was inside the chest pocket of my shirt and I got sweat due to some physical hardwork. I'm still not sure though as to what caused the problem.
I would really appreciate if somebody comes up with a solution. Yes, pressing hard the home button has not worked for me either.

Home Button + FPS not working!

Today morning (about 6 hours ago), i was having bath and i picked up a call and after i got out of bathroom i saw that my home button was not responding. I tried rebooting and clearing cache. Nothing worked. I was on exodus at that time. Now I flashed oxygen OS 3.0 hoping it would work. But no luck
Can any1 tell me a solution??
PS - I havent tried charging solution (draining battery completely and full charging)
- Look at the Screenshot. Does it say 'PASS'?

Can any1 help me??

Yes bro... I hd sffr from this issue and solving by this way...
1)Reflash ur exodus modem on the rom
2)this will surly work
Flash h20s mm rom ... Then u cnn see ur fp worlng..and again go to ur dzire rom...

I had same trouble, flashed many roms official and developped, tried many tricks found in the web.... NO SUCCESS....
Finally i have opened my phone, touched the flat connection inside close to the home button, restarted my phone..... and all was OK AGAIN.....
So I definitively think it's a problem of contacts....
Take a look here: http://forum.xda-developers.com/showpost.php?p=66396613&postcount=46

Thanks I'll try both methods

With the mine you loose your guaranty!

Okay. btw @neelsolanki
Both methods didnt work.
I think i have to go to service center. I think this might have happened due to wet hands

I've now had my fp sensor & home button die twice, the first time I tried everything under the sun, I reflashed all the things, tried stock everything, tried my luck with the contacts and also did the battery drain trick twice.. All to no avail.
I then gave up and accepted it for dead whilst waiting on a replacement button to be delivered, but before I got the chance to swap out what I though to be bad components unexpectedly the home button returned all functionality just like that.
It's now happened twice, and both times resolved itself frustratingly mysteriously.
Try not to be too worried about it all, enable your software keys and wait it out for the next 3-4 days.
And also, the first time my home button died I'd been using a wet cloth to dislodge dirt lodged in the cutout around the home button. So even seemingly water damage isint the be all and end all..

This worked for me:

Backup all your data before doing it. It wipes all partitions, including internal SDCARD.

This worked for me
after I tried
flashing different roms
battery drain trick
holding home button, then force power off (after I did this, the fingerprint part worked, but the home button was overly sensitive, I could have my finger 3 inches away and it would detect it)
clearing cache
full wipe
full factory reset
I might use some rubber cement or glue to hold the connections in place, but im going to run with it for a while to see.

I put my phone this night in container of rice. Hoping it would solve the issue. Still it isn't working[emoji20] . I'm afraid of disassembling the phone. I think going to service center is only the hope

My device doesnt detetct in the tool. It stays 'RELINK' in the device manager all time. I tried everything

This http://forum.xda-developers.com/oneplus-2/general/guide-helper-zips-to-switch-oos-3-0-oos-t3351253 fixes the home button for me. Use LP.zip as the post says, that made both the home button and fingerprint sensor work perfectly for me in CM 13.

Pressing the back or the Recents button simulates a touch on the screen

Every time I press the physical Back or Recents button of the device, a touch is simulated on the Screen.
It's quite a weird issue to explain over text, so here is a video of the issue (streamable{dot}com/nl064)
The phone is a SM-G531H. I tried some ROMs from the Original Development group (Ressurection Remix,Lineage Stable 3 and 2,ViperOS) and the issue persists on all of them.
I'm pretty sure it is not a hardware problem, because it didn't happen on the stock ROM, and it also doesn't happen in TWRP.
All the ROMs I tried where flashed with TWRP 3.0.0-0 and used the PICO 7.1 Gapps from Open Gapps.
Here is the Logcat(goo{dot}gl/uWTNZh)
It was captured from ViperOS, since this is the ROM that is installed at the moment, but if needed I can reflash the other ROMs to provide logcats.
Is there any fix/workaround for this?
Thanks in advance.

This could highly be an issue within your touch screen, you can get it changed at repair shops for cheap.
Or if you think this is a software related issue you can test this by disabling both back and recent then tap them to see if the screen still reacts the same way.
If it does, it's most certainly an issue with your screen.
Maybe just some dust built up under the screen so I'd try cleaning it before sending it to a repair shop.
You can also try other TWRP's cause that could also be the issue.

Well, I've tried disabling the hardware buttons through the ROMs and the issues definitely persists, though it doesn't happen on TWRP.

Now that you mention it, The phone does have a pretty old screen protector. Gonna try removing it and giving the screen a good cleaning to see if the problem still persists.

LG G6 fingerprint option gone

Looks like common problem, suspect it surfaced after recent upgrade to Oreo. There is a popup that says "Can't read fingerprint blah blah, if problem persists, reboot". Trying to access the fingerprint option, it is also gone from the Settings menu. Also have multiple agents with given administrative rights since I use this phone to access office emails and stuff, it does give them the right to delete fingerprints i suppose, but somehow it just happened out of the blue one day. Repeated rebooting, holding down both volume up and down type of rebooting, clearing cache, doesn't help. Based on simple search it is common enough this problem, but no good solution.' Stock, non root.
Will be grateful if anyone has any ideas. Thanks.

Try this. Turn off phone. Hold down power and volume Up and Down together for 10 seconds. It will start in hardware control mode presss power button and phone will restart. This should clear the fault.

Thanks for the suggestion, Sir! Much appreciated.
Actually that was one of the things I tried as well, didn't work though.

Try squeezing the phone a bit in the area between the power button and cameras. I've heard multiple reports of this working. Seems to be a not-so-great physical connection to the sensor. The newer software may be more picky about it.

I have the sprint variant. My fingerprint reader went out some months ago. I've heard some people were able to get it back, but I wasn't one of them. I'm glad I had the second year warranty now. I had to send it in to LG. They are sending me a whole new phone.

The exact same thing happened to me a few weeks ago. I tried everything possible, but nothing worked. I only had a year of warranty, and it had just expired 3 days ago. I had to send it to the LG service center. They replaced the entire back panel and put it back using the water resistant glue (I did end up paying for the repair). But my phone is as good as new. I suggest you do the same thing if you want it fixed.

This worked perfectly for my lg g6. You're a life saver. Thanks so much

I replaced the glass back and fingerprint sensor myself....and trust me, when it comes to ANYTHING D.I.Y. I am useless....but even I found it simple.
Matt

In most cases is just a sealing tape stratify itself and because of this fingerprint sensor lose connection. Before you replace whole back and sensor you can try to replace sealing tape, in 90% cases I had with G6 it helped.

I solved it with another trick
I removed back cover and noticed the erased thermal paste under motherboard on SoC and glass panel
I cleaned it and applied new one put back cover now it is working without problem
Squeez is not permanent solution
