[Q] All Nexus 5 sensors mysteriously non-functional?

Update: Sorry about the title, it should be "[Q] All Nexus 5 SENSORS mysteriously non-functional?"
Well, I usually don't post under Q&A, Help & Troubleshooting unless I'm stumped...
I was flashing an OMNI-hammerhead update a couple days ago on my N5 and noticed something funny, the orientation sensor on my phone didn't seem to work, and I couldn't tilt my phone anymore. I quickly googled the problem expecting somebody with a similar problem but I haven't found one yet... I figured it was just a bad build, so I opened up TWRP and reflashed the zip for my original working OMNI install. The orientation sensor still didn't work... So I booted back into recovery and did a systen-data-cache-dalvik wipe and reflashed OMNI. Still, the sensor wouldn't work. I installed Android Sensor Box and opened it up and it said the only available sensor was the sound sensor. Furthermore, when I was taking a look through the sysfs none of the usual device firmware directories were showing up. `lsmod` seems to show that all of the kernel modules are loaded for my phone, and re-flashing my phone to stock android didn't help either. Finally, today I decided to back up my /data/media folder and reflash everything, including the radio and bootloader using the Unified Android Toolkit. Still, after all of that, the only sensor that shows up is the sound sensor. No compass, no accelerometer, nothing. What should I do? What should I try?

[Q] Help! Lost all sensors after ColorOS -> CM11

Hi all,
Got my OnePlus One last week. It's a Chinese version that comes with ColorOS. I immediately tried to flash CM11 nightly onto it after I checked the phone is working.
For some reason I thought I could flash CM11 directly, and so the first thing I did was installing TWRP 2.8.0.1. Then, I copied CM11 zip in to /sdcard , booted to TWRP recovery, wiped all partitions (including System) and then flashed CM11. In hindsight, I believe it was the wrong way to get CM11. I could have wiped something really important (sensors drivers?) when wiping System.
Initially, CM11 nightly seemed to work OK. Then I noticed the Auto-Rotate is not working at all. I installed CPU-Z and *gasp*, there's not a single sensor listed in the CPU-Z Sensors tab!
I spent hours today trying various methods (flash CM11S, flash ColorOS, flash /persist, /reserve4 partitions). However, the sensors are still dead! Besides auto-rotate, I think auto-brightness, proximity sensors are all dead.
Is there any way to get the sensors working again? Your help is much appreciated!

Try http://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541 and see if your sensors work after restoring to factory images.

Someone else said only twrp 2.7 is supported for opo, another guy had similar device breaking problems with 2.8.

I'm using TWRP 2.8.0.1 and have no problems. TWRP 2.8 had problems, but 2.8.0.1 resolved them.

Thanks a lot for the quick reply, zephiK! I've run flash-all.sh and I'm in CM11S now.
CPU-Z no longer shows an empty Sensors list! however, only the following 4 sensors have readings:
AK8963 Magnetometer
AK8963 Magnetometer Uncalibrated
TMG-3993 IR_Gesture & Proximity
TMG-3993 Ambient
No readings for the rest...

Does auto rotate work? I'm not really sure how your sensors disappeared in the first place, its very odd.

/system is wiped on every ROM flash anyway so that's not the reason. Glad it's working better at least. Any more issues with the sensors other then some not showing?

Nope, the auto-rotate is still not working.
I've just rebooted CM11S, and... the Sensors tab in CPU-Z became empty again! This is very strange indeed...

I think t is a kernel problem,
Maybe you van flash the original boot.img

Rebooted again. The list of sensors are showing in CPU-Z again, and the same 4 lines have readings (AK8963 Magnetometer, TMG-3993). Still no auto-rotate.
My gut feeling is that there is a low level corruption in one of the "special" partitions. By special I mean the ones that are there but not included in any of the ROMs or factory images. Unfortunately, I don't have a NANDROID backup to restore from (Huge mistake on my part).
Is there a way to download an NANDROID image containing those special partitions?
@gurby1, I thought about kernel problem too, but I've tried flashing many ROMs and kernels:
CM11S 33R
CM11 Nightly 20140296
Franco Kernel r20
ColorOS 2.0 beta
ColorOS 1.2
and the results were the same - broken auto-rotate.

Bump. I'm still looking for a full partitions dump of the OPO.
Something similiar to this one for LG G3: http://forum.xda-developers.com/showthread.php?t=2766437

Hello,
Did you find a solution ? I have exactly the same issue as you. It even worst, I don't see any sensor on my device. I have installed many ROMs without any success. I hope it is not a HW problem
Thanks.

Guys.. I also have this issue..
Glad if there any solution on this...

Same problem
Guys any solution yet? I'm getting annoyed by this so much.. Please post here if u have found any solutions. Thx.

I also have the sensor problem which is all sensor is "not supported" in antutu and empty in CPU-Z sensor tab. I fixed it by flashing the persist.img from this thread http://forum.xda-developers.com/oneplus-one/help/fix-brickloop-audio-fx-fc-efs-corrupt-t2879061

I know it's a very old topic, but was someone able to recover the non working sensors? It's hard to believe it's a hardware issue, as the proximity sensor should be completely separate from the e.g. accelerometer...
Tried flashing all .bin files via fastboot with no luck...

Tried flashing everything, modems, persist.img, etc. Nothing helps, so seems something is toast in the hardware...

CM12s Proximity sensor issue

Hi , i've updated my Oneplus one to official Cm12s.
My screen wont wake up when call comes , i have to double tap / press power buttom in order to see call screen.
Its happening specially when sensor is coverd or phone is in my pocket.

So i attempted to create this thread , please help if you know how to solve it !
Thanks

Try flashing the latest Lollipop modem:

I am having an issue with my proximity sensor not working at all. The phone goes blank during a phone call and I cannot wake it up until after the call is over.
I am using an unofficial nightly build for CM11 from a few days ago. This was a recent downgrade from the recently released official CM12.1 nightly because I was not pleased with it's stability.
I used an app to see the sensor values and the light sensor works while the proximity reports nothing. Which modem should I try to flash for CM11 to try to get my sensor back?
I read the proximity sensor and the light sensor are the same hardware unit. Is this true? Or is there a chance I have to warranty my phone?

Is it possible to flash the modem with cm (stock) recovery? My device is not rooted (bootloader locked).
I'm on cyanogen os 12. (ota update).

No, you need a custom recovery. Just unlock your bootloader, simple. It really should be unlocked anyway, you'll be screwed if you get into trouble and need to flash the stock images, because it's at that time that the unlock command won't work, and then you can say bye bye to your phone.

Not fixed !

Proximity sensor not working
I'm on COS12 and my proximity sensor isn't working as well.
Tried reflashing the rom (not clean install but just reflash), and wiping cache and dalvik, but no luck
Also tried the oxygen modem, it gave me no result either...
What should i do now

I downloaded the sensor app and it did show that the proximity sensor was not working.
1) Flashed full CM modem, proximity fixed, no text/notifications on wifi. I know because I sent text with a different phone through WIFI, nothing popped up. I turned off WIFI and I get the texts.
2) Flashed 12.1 CM, same behaviors as above.
3) Flashed back to Team Nocturnal's 5.1.1 build, still same result.
4) I flash CM11 05Q modem, I get notifications/text on WIFI, but the other end is I get the proximity sensor issue; phone doesn't turn off while on a call and it activates the screen.
Still no solution or fix. Just FYI I am an at&t customer on the west coast.

I've some issue related to yours with proximity, but before trying to flash with new firmware - want to ask some people who know more about this than me.
My proximity sensor works good, screen disables during calls, enables while I've put my phone away an ear, BUT it stops working in random situations. I'm using an option to prevent phone unlock with proximity sensor, but phones somehow wakes up in my pocket. After restart all backs to normal. So I think it's not HW related issue as proximity sensor works. Do you think that changing firmware might help?
I'm on latest COS12.1S ROM (updated to second OTA). On COS12S all works good with disabled ambient display option, with enabled same issue. On COS12.1S tried to disable ambient display but no success.

Need help restoring s6 edge hardware functionality!

Hey guys, I recently flashed the Stock ROM PI3. The flash was successful, but I soon found out I have lost a lot of functionality in my phone. My sensors stopped working. My phone doesn't count steps anymore, can't auto-rotate, IR Blaster doesn't work, Heart rate sensor doesn't work, waving your hand over the front screen doesn't wake the screen anymore. The only sensor that seems to work is the fingerprint sensor. I have tried wiping data/cache and reflashing the stock ROM, at the link mentioned earlier, but nothing has solved this issue. If anyone has any idea what is going on, that would be very helpful!

Try to download the firmware again and then try flash it. Also make sure you have the latest version of odin

Problems with my Xiaomi Redmi 8A

Hello people of XDA Forum,
Since a couple of years I own a Xiaomi Redmi 8A, which I ordered brand new on AliExpress.
After a couple of failed attempts to install a Custom Rom on the device, I still have an unlocked bootloader
and a "offical" stock firmware on the smartphone installed. Sadly now occurs an other problem,
frequently the screen "freezes" when I want to use the touchscreen. Sometimes when I put the power-button
and pressing it another time the screen responsed to it. But not always, it's getting very frustating when
for example I play "Call of Duty Mobile". My question is that I want to know of the problem is software-
or hardware based? Hopefully you can help me out, thnx

Have you modified anything in your device recently? No? Then it's probably hardware issue.
Do you have any damage to your phone? Then it's even more likely to be hardware issue.

Thanks for the reply. Now I have this problem for a couple of weeks sadly... There is no visible damage on the
device, but I have dropped the smartphone a couple of times out my hand... So I have this problem and I thought
that a firmware upgrade might help me out, but the problem still remains.

If you think the damage to your phone is significant enough for it to affect your screen then maybe you should send it for a checkup.
Although you can try using different ROM to test if it works since it's probably much cheaper to do so than fixing the screen.
But don't flash an OTA update, flash latest stock ROM manually or flash a custom ROM. That way the settings are reset, you can backup your data with TWRP.

Allright, thank you very much for the suggestion. Finally I managed to flash an older Fastboot ROM through
the "MI Flash Tool", which solved my touchscreen problems.
