Question about moto g6 hardware - damaged finger print scanner - Moto G6 Questions & Answers

(solved: Decided to keep the post instead of deleting it in case someone else faces the same issue. So it was just broken scanners. Got a good one and it worked perfectly. So far no heating issue. So point is the over heating could only mean its a broken scanner and not a main board short or anything.)
So I got a used g6 with a broken screen and non working fingerprint scanner. Switched out the scanner but it gets extremely hot
and doesn't function. I'm wondering if the replacement scanner is broken or if something is wrong with the main board.
There is no other problems with the phone.
Also, I'm wondering how does android 8 handle hardware changes. Because when it was factory reset, it had the old
broken finger print sensor on it. So does android just ignore activating finger print scanner related files when its installed since it didn't detect the scanner? or
is the OS supposed to recognize the replacement scanner and make it work without any extra steps? Is there any way to tell the OS to look for hardware changes and install
needed system files? I'm looking for any expert help with this if you have clear idea what's going on. Thanks.

Calibrate accelerometer and/or gyroscope

Hi!
I am facing problems with the orientation sensors (accelerometer and/or gyroscope), because installing several applications to test them (or use games), it is clearly observable, that they are a bit off (with enough to be disturbing when required). For example, games or tests that simulate a ball, and my phone is laying on a horizontal table, the ball rolls quickly to the edge of screen. This happens as well with the built-in tests in the "service menu" of the phone, for accelerometer and gyroscope also.
Do you have any suggestions how could I calibrate these sensors globally (for every app)?
Thanks.

factory Reset ur phone and then use PC companion app to Repair Firmware...
this can wipe current data and install fresh firmware on ur device
:good:
Hi,
I have the same problem. Only the x axis of the accelerometer seems to be affected : it show a value around 1 instead of 0 while the phone is sitting flat. Y and Z display normal values.
All the software solutions I have tried have had no effect at all... It seems the built-in test reads raw data from the accelerometer. It is hard to imagine how this can be a hardware problem though...
Anyway, in my case I believe a software fix (x=x-1) would do the trick but I have no idea how to do such a thing ! Any help ?
@vekto : Have you solved the issue by any chance ?
Would anyone care to try the accelerometer tests and post their results ?
Typing *#*#7378423#*#* will get you on the service menu. The two significant tests are "accelerometer" and "gyroscope".
I'd post some screenshots myself but I'm not allowed yet...
I'm having the same problem now. It seems one axis is affected. Haven't found a way around so far. This is sad because it affects the images taken with Google Camera Sphere mode. The images are badly aligned together with glitches in between. My phone wasn't like this before.
Either a SW fault - might be able to calibrate with GPS Status & Toolbox app, for example - or a FW fault - and reflashing ROM might help (highly unlikely) - or HW fault - the sensor has moved on the board (which is a bad sign anyway, might be on the way to disconnecting itself).
I sent mine to Xperia Care and got it back with the accelerator fixed. Still unclear if it's a HW problem...
It came back with a white spot on the screen (near the power button) though... so I sent it back again
I'm also having issues with the gyroscope. Installed Bubble app to calibrate the gyro. It showed the gyro was of a couple of degrees. Unfortunately the bubble app calibration doesn't work in a game like Need for Speed. It's very difiicult to achieve good times in the game right now since I have to hold it tilted to the left to go straight ahead.
So if anyone has a fix or workaround... Please do post.
Same problem, Seems after factory reset whith wipe dalvik cache.
any solution?
02nd March 2017, my autorotate has completely stopped working, restart, safe-deposit and reset do not fix. Diagnostics show Gyroscope Light Sensor and accelerometer failed testing, 3 years of same issue, surely there must be a fix that works by now?? ( please note, " turning it off and on again " does not fix it )
Helps Please
I have the same issue. Since last week, gyro, accelerometer, light and proximity sensors stop working. I've tried reflashing stock ROM without success. I have not warranty (almost 3 years old), so I even try to disassemble , disconnect an reconnect every flex (I don't know exactly were the sensors are located on the board). After that I get almost 8 hours of fully functionally sensors and then, they stop working again, so I'm almost sure it's a hardware issue.
Same problem for 3 years
I'm just now getting around to doing something about this. As my power button stopped working I can't post requested screenshot without going to the pc. I have been shopping new (fall 2018) phones after having the Z3+ since release. In my research I'm finding the phone still is better than Samsung, LG, and the pixel3 for me because the 3.5mm phone jack is mandatory for me using my device with an i-rig midi requiring both that port and the USB at the same time. I'm going to do everything I can to keep using this phone till it falls to dust. It's one of 4 Sony I've bought since the day Z1 came out of t-mo. I look forward to testing solutions. :good:
Some time after my post, I bought a new jack/proximity sensor flex and replace it. This solved the issue, but weeks later, the bottom portion of the touch screen becomes unresponsive. May be I have done something wrong... may be programmed obsolescence...
Hi I'm facing a problem of my gyroscope I don't know which one is not working a gyroscope or accelerometer. My gyroscope is so delay when I play pubg mobile and I can't also calibrate my Gsensor it always says FAIL but I put in a perfect flat surface please please please help me with this problems

S-Pen removal trigger misfiring

I am having a hardware issue with my phone. I was wondering if there might be a software work-around to it. The sensor that detects the removal of my s-pen fires off randomly. I've set all of the settings so nothing happens (no air command, no vibration or noise) when these misfires happen, but it still wakes up the phone randomly. The misfires do not happen when the pen is removed. I tried a new pen but that didn't help - so the issue is on the phone.
So, I was wondering if there is some software solution that will trick the phone into thinking that the pen is always out - basically disable the signal from the sensor. I opened the phone and I found the magnetic sensor that triggers this but I really don't want to remove or replace it. It would be hard if not impossible since it's right on the board. I know this is an odd problem and I've not seen any reports of anything similar, but I was hoping that there might be some ideas out there. Thanks for your help!
PS: My note 4 is rooted.

Flash cyanogen based roms like cm12.cm13.resurrection remix
This roms are stock android like nexus phones and actually spen dosent works except with 3rd party apps.the spen detects aircommand only with touchwiz roms. so you dont have to worry if the pen is in or out it wont detect.if Hope that helps

Thanks. I think I fixed it. I had replaced my screen some time ago. The adhesive had become undone and it was pulling away from the board. I opened it up and glued it down. Seems to have worked.

Fingerprint sensor stops working

Had my S8 plus for about a month now. Every 2-3 days or so, the fingerprint sensor stops working just randomly. Will work perfectly, then just out of nowhere, doesn't respond to anything. Disabling fingerprint security and re-enabling doesn't fix it. Trying to go into applications- system apps- fingerprints, and trying to force close it won't work as it's grayed out. The only thing that works to get it working again is a restart. Not the end of the world I know, but having to restart it at the most inopportune times is kind of annoying. And paying this much for what amounts to the top of the line phone on the market right now, and having one the most important functions just stop working all the time is crap. And no I don't want to use the iris scanner, or pin, or pattern security. I want to use the fingerprint sensor.
Searches around the web indicate this is pretty common. Anyone else on the VZW S8 or plus having this issue? Anyone know if a fix is coming down the pipeline? I'm pretty sure this would be a software issue as it works 85% of the time and a simple restart gets it working again.

Some other threads on XDA have said that disabling fingerprint scanner gestures fixes it. I haven't ever used those and I have never had a problem with the sensor. It isn't as good as the sensor on my Moto Z Force Droid was, but it is pretty good.

Yeah, I disabled that last night. Waiting to see if that works or not. Just thought I would post in the Verizon specific forum to see if any other Verizon users are having this issue. Pretty sure it's a software issue, and am just curious about differences between the Verizon software and other carrier specific software.
Always had the gestures disabled and I have noticed this, but it always goes away with time for me. I thought it was just because I was sweaty at the gym, but it doesn't even know that I am attempting to use the scanner. Then, it happened outside the gym. Goes away in just a couple minutes, thought it was just me.
It seems that the fingerprint scanner is more reliable when the screen is off than it is when the lockscreen is on looking for iris scan.

Note8 Sensors error - Any of you faced with?

I have Note8. It has a very strange sensors error, as below:
- All sensors, from proximity sensor, light sensor, to GPS, iris scanner, and all the other sensors do not work at all.
- In the app like Phone INFO Samsung, CPU-Z or AIDA64, in the Sensors section, all sensors do not work.
- The Auto Brightness function does not work (due to the light sensor), the brightness of the AOD screen is also not adjustable.
- When making a phone call and move the phone close to the ear, the screen does not turn off due to proximity sensor.
- Auto Rotation function is not working (due to rotation sensor).
- Google Maps shows inaccurate location. Other apps that rely on GPS (such as the speedometer app) are completely not working.
- The iris scanner function does not work either.
It was about two weeks ago. I've Wiped the cache, restart the phone but does not make sense.
Yesterday it suddenly returned to normal, I don't know why.
But today - while I'm typing this post - all sensors suddenly do not work again.
Any idea about the error and how to fix it?
Thank you guys
Best advice I can think of is to factory reset and see if that alleviates the problem.
If you did not do anything firmware-related, or you did not drop or submeged your device, the best you can do is to make a warranty claim, pure and simple, if you have no way to make such claim, well, next time you should consider getting a device from an official source
I've read other users have had same problem. Ones I read said it was motherboard issue had to have sammy replace it.
Thank you guys
There is also built-in sensor test. Open dialer and dial *#0*#
I noticed a problem when I was playing Asphalt (racing game on me Note 8). I am unable to use the Tilt controls to move the scar.
Testing out the Sensors using *#0*# at the dialer revealed that all the SENSORS was faulty.
I reset the whole phone just now. The issue is still there with the sensor. As expected Auto rotation doesn't work.
Running the latest version 8.0.
I recently changed my motherboard (under warranty) 3 months back cos something was faulty. Seems it may be another motherboard issue.
Anyone else in this thread solved the issue?
Hey everyone I'm facing the same problem. All sensors stoped working but they were working before on 7.1.1 and i updated my device to oreo and realized all sensors stoped

Sensitivity issue

Hi there,
my Redmi Note 9 NFC version has a problem with its touch screen. For me, it is too sensitive, which means my finger hovers about 1 mm above the screen an the phone detects a touch, which is clearly wrong. That leads to wrong typing and all sorts of other annoying issues.
Does anybody of you know how to turn the screen less sensitive? The tips I read on the Internet are not applicable to the Note 9 or are simply useless.
Your input is highly appreciated!
Thanks!!!

If you searched the internet and found no one facing that issue on the same device then it might be just your unit with this problem. Anyways your phone has a warranty and contacting Xiaomi's support is recommended.
Sorry, don't think I can help you - I haven't come across this problem. Just tried to reproduce it myself but can't. Are you using a screen protector? If not, you might find it helpful to use one - they tend to dull the sensitivity a little, though if you're getting touches detected without any contact being made I suspect a screen protector might not help
that's unfortunate that no one has the same problem, which means it could be a hardware problem, which means I need to return it or take it to a service center.
I'm using the original screen protector, didn't tear it off. I had hoped there was some internal feature within the CIT, for instance, that I can use to recalibrate the touch screen, but it merely checks the touchscreen.
Hmmm, need to think about it a bit more.
I also have this problem , . I have a Redmi Note 9 pro EU version . My finger gets registered about 1 mm above the screen . Although I don't seem to have a problem with typing, it is annoying as sometimes the screen registeres my finger without touching by the screen witch leads to all sort of problems , ( like wrong friend requests on Facebook )
