Broken accelerometer/orientation sensor

My z1c has an accelerometer that is broken. This means auto rotation doesn't work for example. Sometimes i can get it working by calibration and/or restart, but after a while the sensor will be off again. I'm testing with the app "android sensor". At the moment the sensor is stuck as if I'm holding my phone horizontally.
I'm running latest software, 14.3.A.0.757
Since i bought it while travelling in Thailand (not the smartest, but my old phone broke, so what to do..), I'm trying to see if anyone here has experience with this, before contacting Sony.
As far as my searches go, i have not been able to locate this as a known problem.

My accelerometer works perfect i have my phone since sunday. Maybe you should perform.a factory reset if that doesnt help its defenetly hardware issue.

I got the same problem. Bought it about 9 months ago in Uk. Since few months im on .108. I don't think that firmware is a problem coz it starts about 2 weeks ago. Accelelometer stop working every now and then. Reboot helps but not for long. Gonna contact o2 as still have warranty.

guys i have the same problem with my z1
seems like some software problem ..
because if the hardware is broken it would not start working after restarting
did any of you , opened your phone for replacing or something?

I had this problem too. All sensors would stop responding and give no readings in the service tests. A reboot would fix it for a couple days but the issue would always return. At the time I was running a 108 rom that I had downloaded from this forum, Russian I believe. Recently PC companion told me I had an update but the version was also 108. I did the update without wiping data and I haven't had the problem with the sensors for about 3 weeks.
Still not sure what caused it, it didn't start with my first loading of 108, but some time after that. My best guess is that some app hosed something up and a software update fixed it. Hope it doesn't come back.

Just rebooting the phone worked for me

Same here. I believe that the problem started when I changed my screensaver to one of the animated backgrounds with planets on it. On a first run it would work and rotate the planet render in the background when I tilted the phone. The next day it stopped working. I mean, the screensaver was on, but it would no detect orientation from the gryroscope. The screen also stopped autorotating when playing YouTube videos from the app, the compass app wasn't working and so on. I installed a few small sensor monitoring applications and all of the gave me no readings for the accelerometer or gyroscope sensors. Some other sensors were disabled, such as proximity, illumination level detect and so on. I was afraid that the accelerometer could be broken from humidity, pressure or a small drop that happened, but these small incidents could not explain the problem by their own (specially since the Z1c is thoroughly tested against all of these). I thought of maybe a faulty motherboard construction or whatever and starting considering the possibility of taking it back to the store for the guarantee, but before that I googled and came along this site and a couple others.
I fiddled a bit with Android menu config. settings but to no avail. I completely discarded the factory reset advice (that's SO crazy!).
When I rebooted the phone (no reset, just a regular off and on again process) all sensor readings were back on. I still didn't have the chance to check whether the problem might come back in a few days or not.
The cause may or may not be on the planets screensaver app. I also used Google Earth, YouTube and a few other apps the day sensors stopped working, but none of these gave problems in the past.
Fingers crossed for this issue not reappearing.

Hello everybody on my Z1 accelerometer compass gyroscope and light sensor does not work! any help please?

Yesterday I've had the same trouble, screen orientation stopped working. Apps using the acceleration sensor stopped working (Google Sky i.e.)
First I did a factory reset without any change, still no function. As I still have warranty, I wanted to prepare the phone to send it to Sony for repair. So I switched the phone off, removed SIM and SD (what I haven't done before) and switched it on again. Then I did a factory reset once again and here we go the sensor went back to work.
Probably the factory reset is "deeper" if there's no SIM and SD card in the phone? Who knows.

[Solved] Sensors not working

Hello,
my wife and I both have a Pixel C because it is very convenient for surfing etc.
Yesterday I realized the ambient light sensor on mine stopped working (adaptive brightness not working) and today on my wifes Pixel nearly all sensors stopped working (screen rotation, compass, ... not working).
Using the app "Sensors Multitool" on her tablet I only get those menu entries: "Battery", "WIFI", "Light" and "Distance" (translated names from german). Those are all working.
On my own Pixel I get many more (e.g. Gyroscope, Acceleromator, ...). Light and distance are shown but both receive no useful/no values from the sensors. All others beside of those two are working.
I already tried to factory reset and wipe cache on my wifes tablet - not working
Any further ideas? To me it sounds like hardware defect on both tablets..

There was an update to the secondary processor (EC) code with the Feb OTA, so its possible that its a software glitch - assuming you have updated. Judging from the current known issues, there seems to be some source of variation which makes testing some of this software tricky...

I flashed the old version (6.0.1 (MXB48J)) but sadly it didn't work I guess this also downgrades the code for the EC? Any further ideas? Looks like we've got to send both of them back for a replacement....

Flashing the latest Android N Dev Preview fixed the sensors for me!!
My wifes Pixel got replaced without any problems So everything good from our side.

Rear camera/Flashlight not recognized

My rear camera suddenly stopped working. My phone didn't get any hurt in nowhere, just suddenly it stopped working. I was takin photos since 10 minutes before, I locked the phone and I noticed that Torch tile disappeared. I thought it was a bug and I didn't care anymore. The day before I noticed that even rear camera stopped working, I was trying to take a photo but the "change camera" (from front to rear) disappeared in every camera app I was using, camera apps opened by default with front camera opened. I tried to reflash ROM thinking that it was a ROM problem (even if I was using the same rom since months ago and I've never had any kind of problem), no results. Reflashing everything starting from stock firmware, no results. As a last hope, I tried to replace the rear camera by buying a new one, but the problem it's still here. Could someone that experienced the same problem, tell me where the problem could be? Or maybe some possible fixes, every kind of help is appreciated. Thanks.

Same
I have the exact same problem. After wiping the cache the rear camera is recognised and I am able to take a picture with it (which is not saved into gallery) but about 5 minutes later the option to switch to rear camera has gone and all camera apps (including social media such as snapchat) is stuck on front camera. This leads me to think it's not a hardware problem but rather that of software with which I am running cm13 nightlies that I have updated every day for the past week in the hope it will be patched.

I have this exact same problem on my d855 too..!
Sooooo frustrating, I've been looking everywhere for a fix, tried full factory reset the other day (I'm running full regular stock with no root or anything), and sadly that didn't work either... I'm glad to read someone has tried changing the camera hardware, cos that was I step I've considered taking, but I now know would be a waste of time and money...
But still, the problem persists..!

I don't think that's a software problem simply for one reason: I'm on the same rom and kernel since months and camera worked fine. It stopped working suddenly with no reason.

Yeah now you made me understand why the camera worked for some minutes. I'll try clearing cache after installing new camera module. I'll report the result. Thanks anyway.
Edit: It's not working. At first boot, systemUI doesn't load well, when I reboot everything works fine but rear camera isn't working. Maybe late I'll try with phone's camera. Now I'm using the new one bought some days ago.

same here!!!!! I'm using LOS13.1 on my d855 and i can't fix it... any idea?

What OS are you guys running? Is everyone experiencing the issue on Cm13?
Also try cleaning the camera connections really well.

I have same problem. Although i expirienced it first time on Lineage OS 14.1. Now 30B, but it still not working. I was listening to music through external speakers, and suddenly it stopped working. Music app was "playing" but i couldnt hear anything and when i exit the app my phone just stops working and starts being laggy as hell. Later that day i found out my camera is not working. I tried reattaching cam connector but it did not work...idk if i should order a new camera or it might be a software fix or something

same problem
happened to me after upgrading to 6.0 , downgraded back to 5 with no luck , even opened my phone and released and reconnected the 3 cables inside with no luck at all . don't know what to do

It's "good" to see other people with the same problem as me.
I replaced the camera and it still won't work.

I'm afraid that it might the problem with our motherboard...How can software block our camera even tho all of us fully reinstalled ROMs/Modems etc? It would be awesome if dev would see this and tell us what is the actual cause of this

If you reinstalled the entire OS using a TOT method, no files are left behind. This is more likely a hardware issue.
The Camera module is extremely close to the problematic hot chip on the G3 so it's not impossible something got messed up.

I have a d852 in Canada that doesn't get hot and I'm having this problem too. Going to order a new camera since I know this is a hardware issue. Hopefully fixed the issue. Not cool having no rear camera or flashlight

It's impossible Every G3 gets hot...you either are not heavy user or idk...but every G3 that i've held had the issue of overheating at some point...and indeed it can ruin everything...imagine 120C on your processor...that kills everything around it...idk if my processor got that hot as i've seen in some cases it did on internet, but it did go up to 90ish...and that is too damn hot

FIX ISSUE be Done

Pixel 3 XL: Camera encountered a fatal error; blank camera

Starting today, my camera opens to a blank black screen when I launch the app. If I reboot the phone, I can successfully launch the camera app and take photos. However, if I attempt to use the camera built into Android Messages, Facebook, and even the bar code scanner app I have installed, the issue starts again. I have tried uninstalling the updates to the camera app, clearing data, and I even did a factory restore. I booted up into safe mode, then duplicated the issue there as well (this eliminates 3rd party apps as the cause). Some other threads I have read say to toggle Bluetooth or turn on airplane mode. Nothing fixes the problem.
I hopped in chat with Google Support and they had me follow this guide (which didn't fix anything). They requested the factory reset. After the factory reset, they required me to gather a bug report to send to them. I requested a replacement device, but the support technician declined and said this issue isn't something that can get a replacement device. I am very irritated I spent so much money on this device and it is already (two and a half weeks later) starting to not work.
Has anyone else on the Pixel 3 XL had this issue? Any other recommendations to fix it?

try flash-all.bat from googles factory images. could be a corrupt persist partition

I don't have an unlocked bootloader. That's required for that, right? Would I need an unlocked bootloader to flash the image?

Blank camera screen when camera opened from from another app
I have the same issue with my pixel 3 xl. Blank camera when it's opened with messages app, fb, WhatsApp, Instagram, fb messages. Called Google support and they had me clear cache, uninstall cam updates restart phone and in the end factory reset but it didn't fix it. They can't identify if it's a software issue. They even had me boot up in safe mode and had screen sharing session.
After multiple calls and hours of troubleshooting, Google will be replacing my phone. Hopefully the new phone don't have this problem.

No luck for me, unfortunately. I unlocked the bootloader and flashed the factory image. The issue persisted after the flash. I contact Google Support again and they continue to tell me the issue is going to be resolved by engineering and they will not replace the defective device. Total bummer for such an expensive brick.

On support contact #3, Google has decided to replace the device for me. Just FYI, in case anyone else has this problem with their phone. I asked for a manager during contact #2 and didn't hear anything back for 24 hours. The person I got on #3 was very nice and assisted in the replacement order.

Had the same issue with 2 of my pixel 2 xl phones. First one was sent away for 2 weeks and then replaced. replacement one lasted a couple months before it had the same issues, I demanded a RMA from google so i could get it swapped in store. The second phone that was replaced lasted a day, it had a weird bright screen flash when locking, unlocking, hanging up from a call etc. That was also RMA and returned and replaced in store.
Hope my 3 doesn't have these issues.

camera hardware is crashing when used by any app other than the "Camera" app
I have the same issues during one week. What I find is the playground and any app other than the "Camera" app attempts to access the camera hardware, the camera itself becomes unresponsive.* After that, the camera cannot be accessed by any application, including the "Camera" app. There Google support told me the engineers will fix that problem. But I'm not sure if that's a hardware issue or software issues.

I'm wondering if this is a November update issue - anyone try flashing back to first release?

Similar issue here, on November, will try to flash november again and test.
Edit:
and..... did not fix a thing. Looks like it is hardware related or if there is a hardware rev in a specific part that is not coded properly.

I can assure you that it is not an issue with November patch or any patch. I have this issue and I am still running with the stock September security patch that came with the phone. I was hoping that updating to the latest patch would fix the issue, but now I'm beginning to think that won't resolve the problem.

Miui 12.5 issue?

Hi I have recently bought a second hand redmi note 8 pro to use with a drone I have also recently purchased.
everything has been working fine. Until last night 21/07/21 I had a notification of the new miui 12.5 update. which I left to do its thing. The issue is the screen does not respond to touch. it appears to boot up ok gets to the screen shown. I have had it on fastboot screen and also wiped all data (can't seem to get mi assistance to work.)
Has anyone else had the update/ issue?
How would you recommend proceeding.

I have the same problem (Redmi Note 8 Pro Global - MI firmware). After updating from 12.0.8, the touchscreen stopped working.
I had to roll back through the fastboot. I also tried to flash version 12.5.1.0 via fastboot - the problem persists.
The phone had a replacement display module, but with an original one.
There is an idea to try to flash it with a version for Indonesia or China, but so far I have not tested it.

Issue with SIM selection for calling on MIUI 12.5 Global - Redmi Note 8 Pro​
Anyone experiencing this bug with default SIM for call?
The Google Dialer will ask for which SIM to call on reboot even tho I already set it as SIM1 or SIM2 in the Settings.
The workaround is manually reselecting the SIM but only effective till next reboot.

Same exclusive Xiaomi Update Fail Forget about help or information from the official Support.
Connect a mouse with a USB-C to USB Adapter and backup your personal data.

I have exact same issue on this update. I also replaced the screen some time ago. I belive it's android 11 problem, because CFWs like PE doesn't work too. ROMs with Android 10 also seems weird to me, because digitizer keeps "jumping" and clicking random places. Android 9 - all works perfectly fine. I am going to find out which partition is used to use touchscreen and check if it's possible to flash it over PE ROM to solve the problems.

I have some problems after updating to MIUI 12.5.1:
1. Have to repeat the procedure twice for uploading any picture from gallery to anywhere on Internet. It doesn't work in first attempt.
2. Fingerprint sensor shows many errors off & on. 3-4 attempts to open the phone. Tried re-registering my fingers.
3. Option of Completely Hide Notch gone
4. While playing Facebook videos, sound continues, video stops.
Too annoying these bugs are.

Yes, the great manufacturer has kept its information behind the mountain. I have just found a contribution to this in the mi community.
It only briefly mentions that repairs should be made with an official display. I also do not understand why Xiaomi makes such a secret of it and does not give the reasons. Link
I have installed the Global 12.0.5 Stable QGGEUXM and I am also aware of these display anomalies.
Do you have any results in the project?

I've tested all partitions but any of them seems to be changing display driver. So sorry, no luck there, I think we're stuck with android 9. It looks like it is hard-coded into firmware.

I noticed a break in a layer of the display within 14 days of use. There was no heavy use or pressure on the display. Xiaomi - K.O.

How to bring back the option of "Completely Hide the Notch" in MIUI 12.5.1?

I have just realised I didn't update. I was having lots of trouble fixing this. I think my reply from xiaomi was wait for the next update this might fix it.
Thank you to Boo-Kah-Kee, I never knew you could plug a mouse in.
anyway I eventually got it back to the prievious rom by following this Video.
No more updates it works fine.
