[H850] Fingerprint Settings Disappeared. - LG G5 Questions & Answers

Hello all,
I have treated this phone very carefully since I have got it about a year ago just to mention but all of a sudden at work today lock-screen said it could not use fingerprints and then suddenly the settings regarding the fingerprint sensor disappeared. Anyone got any clue on how to bring them back? The button itself is working fine.
Thanks.

No one has any ideas? If I replace the button using my Ifixit kit does anyone know if that would fix this?

If you used your fingerprint button with wet fingers or if some light humidity was near the button he stops working. Wait some time and then restart your phone. Had the same problem many times. Maybe a "safety feature" by LG?

I have left it for a while, I also tried some Isopropyl alcohol as others have advised with their malfunctioning power buttons and that didn't do anything.

I had the same problem, replaced the fingerprint power button module. Now it's working. Just followed ifix

8125 stuck on 3 color boot screen

It says only ipl 2.25.0001 and spl 2.25.0001
I try a hard reset, but when it asks me to confirm by pressing SEND, I press SEND and nothing happens.. press any key and nothing happens, just sits there saying press SEND to confirm...
I tried flashing Cingular/AT&T's rom on to it, it was successful on the screen, but after rebooting, just went back into the 3 color screen...
Does anyone have any suggestions?
Additional info
I just wanted to add, I have searched threads here on xda-dev and other sites, and have found similar issues - normally the other issues have been resolved in one way or another involving a hard reset, which my phone will not complete. When it asks me to press send, the phone freezes at that point and does not accept any key entries (except reset). I would really appreciate any input. I also have a theory-that I may attempt this evening-If you hold the camera button down and reset, it brings up the boot loader screen (if my information is correct)... could my problem be caused by a faulty camera button? Maybe internally the button is remaining closed, which could prevent it from doing anything on a reset outside of the boot screen? Any engineers around that may know this? I am going to attempt (hopefully with low heat) to remove the button this evening... possibly even repair or replace it if the phone works with the button removed...(these thoughts are based on my phone being dropped in the sand at the beach...maybe a grain of sand worked it's way into the camera's button housing and is holding the contact closed)
problem's almost fixed
well thanks for no advice... i desoldered and removed the camera button (button 3). powered it on and the phone works. I reprogrammed the camera to button 5. (i also loaded a new WM6 rom and some other stuff) The last time I opened up the phone, I broke the itsy bitsy super micro tiny lock on the keyboard ribbon cable socket... so now my slide out keyboard doesn't work. I installed a full screen keyboard and set it to the messaging button (button 1) - the messaging button still brings up messaging with just a touch, but a long hold brings up a full screen touch keyboard that works fantastically!!! I am going to dismantle the very tiny micro switch and repair it, then resolder it back on the mainboard to make my camera work like it should again...and find a way to get the keyboard ribbon cable to lock into the socket...then my phone will be as good as new!
umm... thanks???
well congratulations on getting it working again.
tiny switch
I have taken the tiny little switch apart without breaking anything... one tiny grain of sand stuck under the button pressing on the switch plate... now i have to find a way to put the little switch back together... then attempt to solder it back onto the board without over heating nearby components. I have been playing around with Byka's cube... took a bit of tweaking to get it to work well.... not sure if I want to keep it or not... I have been trying to find htc cube, but no luck outside of a rom... which I may consider...but I just spent the past week reinstalling all of the software I use... Would like to just design my own windows for my phone if I had the time... Been working on an ion motor for an electric car...
I would like to thank everyone here at xda-dev. for all the information. Could not have learned so much, so quickly, if it weren't for this site.
oh... and I am using an 8125 (G4) with Faria Crossbow
Have the same problem...
Hi!
I have the same problem (but I don't have much tech know how).
It all started when phone got wet (inc. in battery compartment).
My phone would not soft reset beyond the Bootloader, unless I leave the battery out for a few hours. Then once it loads up, after a short amount of usage 2 things happen: 1) every time I would turn it on (or get a call) it starts in Camera (you didn't report it but you must have had the same experience). 2) the buttons don't work properly.
It finally dawned on me the camera button might be stuck, I set the button to "none", and no more more automatic camera. I still need to free the button altogether as still causing button freezeup and also allow soft resets.
I don't know much about soldering.
Any ideas?
Thanks

[Q] Wake issue during phone calls

I am unable to wake the phone during a call. As soon as I answer a call, or press the call button my screen turns off. I can not wake it with proximity sensor, double tap or power button. There is literally no way to turn on the screen once a call has started. It was random when it started. I had been using Vanir for a while and then one day it started on my phone, and never left. I have even flashed my OG nandroid stock and the issue was present there after flashing to that.
I have swapped ROMs, AOSP x4, BarRin, Stock, you name it, but to no avail. I have cleared everything off my internal, wiped the internal memory, sideloaded a ROM back from scratch and booted up plain jane... same issue.
I am attaching a link to a logcat incase anybody has any ideas. I'm simply lost with this, and it is a major issue considering every time I make a call I have to be ready to take the case off so that I have faster access to pop the back off and battery pull. This is not a way to live.
PLEASE if someone has any ideas on how/where to go about fixing this, I will be grateful.
Not sure if it matters, but after a call ends, I need to wait about 5 or secs before the power button will be recognized. After it's first press it seems to first power off the screen, as though it is awake the whole time, but black and inoperable. After the screen thinks it's off, the second press turns it back on. I have also tried other dialers too, but it totally seems like an integrated OS/Firmware issue at this point.
Are you by chance running Greenify? I was having some issues when sleeping system apps. What Xposed modules are you currently running?
No battery apps installed whatsoever. No battery saving modes enabled.

Sorry a bit tired. I just noticed you stated it still happens after you nandroid back to your previous backup. Do you have a screen protector or anything on it?
Try going to Settings/Call and disable the proximity sensor and see if you have the same results
It's not the sensor though b/c it has 0 results with the double tap to wake and also the power hardware button itself. Holding the button, pressing it quickly, tap it multiple times in a row. Additionally, I do not have a screen protector.

Proximity sensor issues

Hi,
I've just had my screen replaced on the LG G5. However, post screen replacement I am facing the following problems:
- As soon as I dial a number the screen goes black and locks itself. I need to press the button at the back to unlock the screen.
- If i make a call using whatsapp, as soon as I hit dial the screen locks itself
I checked and it looks like my proximity sensor is not working. In the apps that I use to test it, it either just reads '0" for the proximity sensor or "NEAR".
Anyone else faced similar issues or have a solution?
I just had my screen/frame replaced and am having the same problem. Tap to wake rarely works and while making a call the display stays on while phone is to my ear. Did you find a fix?
I fixed my problem doing some Googling. I can't post the link to the thread but Google "LG G5 Proximity Sensor Reddit mobile repair".
"I had a similar problem. I replaced my display/frame myself and the tap to wake function rarely worked and the phone display would stay lit when held to my ear. Following the advice here, I found that there was a rubber grommet around the prox sensor window on the old screen that I hadn't transferred over. It's very hard to see and almost looks like it is molded into the frame. I dug it out with some tweezers and transferred it over and it is back to normal."

Fingerprint sensor/ Lockscreen

Hello,
Long time lurker here and was hoping for some advice/ suggestions.
I have a Canadian S9 Plus (on Bell Mobility) and noticed the following issues/ annoyances:
1) When the phone is woken up (e.g. pressing the virtual home button, plugged into charger, new text message received, etc.), the screen would turn on, continuously look for fingerprints ("Wipe the fingerprint sensor and try again" message would keep flashing) and would not shut off until I press the power button to turn off the screen
2) The fingerprint sensor generally works (e.g. unlocks the phone, swipes to drop down notification window), HOWEVER it does not work to unlock the phone if the phone has been sleeping for more than a few minutes (nothing happens no matter which direction I swipe/ press the fingerprint sensor). When I try to unlock the phone, I will have to press the power button to wake up the phone then swipe the fingerprint sensor. This may be a standard feature, but after pressing the power button to wake up the screen I will always get a message that says "The fingerprint sensor may be dirty. Clean it and try again.". Again the fingerprint sensor otherwise works so cleanliness of the sensor isn't really an issue here.
Has this happened to anyone's phone? I tried clearing cache/ resetting app preferences/ factory resetting the phone multiple times but with no luck. I also called Samsung but the conversation didn't go anywhere.
Any other suggestions? Thanks in advance for your help!
Have not had that issue with mine.
Do you have the finger sensor gesture on?

Tried both finger gesture on and off - no difference with the same issues persisting :crying:
this is the exact issue im facing when i got my s9+, i also thought that it was a factory defect. but luckily recently it didnt came up again and i did nothing. but still continuing monitoring the issue as it is really so bothersome.
Sounds like a defect to me. I'd exchange it.
I have not had any issues. Have you tried re-scanning your fingers? I noticed that this finger print scanner is different from the one on my LG V20. It feels different, and seems to operate different. It's also a little smaller which makes me have to position my fingers different.
I also read the instructions wrong.. I was supposed to swipe my finger during the setup. I was pressing it down. Either way mine works great.
Same issue here, did you manage to solve it?

Not at all - I ended up returning it. Any luck on your end?
Maybe try registering your finger/s with and without a case on. See what happens.
Same issue here. This is the one thing that really bugs me about this phone.

Strange touch screen/nav buttons double tap issue

Am I the only?
I own the Honor 10 64GB Blue from Europe/Italy.
I'm using the honor 10 for something like a month, and I've always had a strange issue with the soft navigation buttons, basically sometimes, not always, whenever I tap the back button, or the multitasking button, it is registered two times, and it is a lot frustrating.
Enabling the hardware vibration feedback, I can tell that is an hardware or software issue because it is too precise. So it is not like my finger slipped and tapped two times.
And I'm not the guy who is installing tons of bloatware apps, (I even deleted half of the preinstalled apps), i just have like facebook, instagram, messenger telegram and whatsapp installed. So maybe not a CPU issue.
So basically what I did was going back to the store, asked for a replacement, and after a week I got a brand new phone, and the same problem happened! So previously I got a Xiaomi Mi5 and never had an issue.
My use behavior consists to do things really fast. But I don't know that has something to do with that, I'm doing the same things I've did with other phones, I owned a Nexus 5 and 5x which also had soft navigation buttons and never had such issue in the past.
I don't know what to do honestly, since no one is having issues with their phone, I've just disabled the vibration feedback for the keyboard maybe is screwing the touch screen (????) I will test it anyway.
And I'm charging the phone with regular USB instead of the fast charge, obviously I've did a lot of hard resets. Now I'm trying to charge it only with the huawei charger
Latest firmware obv. I'm thinking of returning the phone again to get my money back. What a shame, it's a pretty good phone aside from that.
So here is a video attachment showing the exact problem, i just had to tap for something like a minute or two, I've did an hard reset yesterday, only Whatsapp, facebook and telegram are installed, no noticeable CPU load, juts mobile data on
Just look at the very first seconds of the video.
Can't check the video now, but this sounds exactly like the problem I've been having with my Honor 10. In ddition to this sometimes the letter a is not registered. I was going to get my digitizer replaced under warranty,but now I'm not sure if I should. I had this issue from day one.
Similar problem with the touch
It seams related to yours issue my problem. Completely random if I'm on 1 app it minimize, vibrating and the phone go to the home page. Even if I'm in the drawer but not in the home page it turn to the home page.
Is like I've touched the fingerprint sensor, even if I did not. Left at the honor/huawei repair center, back after 3 weeks they did a software upgrade. Now it happens rarely, but still happens.
You guys use some kind of glas screen protector? I had one for some time and had also issues like yours. Some letters werent recognized and also sometimes homescreen button got triggered.
Right now i m using a normal screen protector and all problems are gone.
Same issue here, since day one...
No Screen protector, tried to switch the back Button to the right - but it still exists
Same problem with Honor 9 lite
Using fluid navigation to deal with it , it's less annoying that way , i am Trying to find a workaround for this as well , if anyone know how to fix it.
Let us know in comment ?
Hi, I am too facing similar type of issue with my honor view 20. Please let me know if anyone has got the reason behind it. Thanks.
I never use the on screen button navigation on Honor 10. I was using the fingerprint sensor navigation, and now I'm using Fluid NG.
I don't think my digitizer is broken, since I don't have any issue.
Its all good and smooth.
I just got an Honor 10 Lite this week - I've got a different problem with the navigation buttons.
It's an intermittent problem but I'm sometimes pressing the back or home button half a dozen times before it actually goes home or goes back.
If there's a back button at the top left etc., it will immediately go back.
Enabled haptic feedback and the touch is definitely detected and when you touch the navigation button the screen indicated an circular patch where you touched but the problem remains.
Also tried using gestures, same thing....
Huawei customer service recommends a factory reset, anybody else have this problem?
Well I got a replacement phone, blue this time, instead of black.
For the first couple of days it appeared to be very responsive to touching the navigation buttons but now I'm getting the same requirement to do multiple taps!
