accelerometer gyroscope problem

after i reset to factory settings i cant rotate and play and games that require accelerometer or gyroscope anyone know how to fix this problem or i have to return my device?

Pain in the Ass
Hello friend,
I've been facing the same problem. I gave it back to my vendor who "did something" and twas working again! before I gave it to him, I was pretty sure twas a Hardware problem, bcoz running the g-sensor test in *#*#3424#*#* wasnt responding. the g-sensor wasnt calibrating and an app called AndroSensor wasnt receiving values from the accelerometer.
And now the same problem has returned. I'm hunting online for a solution myself.

does it work in normal use? images rotates?

Try that
Also try re-calibrating !

I had the same problem, booting into Safe Mode and then booting back to normal solved my problem, you should try that.
Btw you can boot in Safe mode with holding volume down while doing normal restart.
Hope that helps

hi there
i've the same problem , i've updated the Hboot to 1.31 and then i flashed JB insert coin version , but still i've the same issue , any idea how to solve it ?? this is driving me crazy

It's first sympthom of dead CPU on OneX. Next will be freeze phone and rebooting when CPU is hot. It's Tegra 3 standard problem.

Here's a *possible* solution to bad compass...

If your Nitro is like mine, then its' compass couldn't find North to save its' life. Or worse yet it might be in the vicinity, but is very sporadic...Makes it just about impossible to use apps like Google Star Maps or get a proper bearing on direction in Nav when you're at a stop.
If you're also like me, you've tried doing the compass calibrations with the whacky waving your phone in a figure 8 to calibrate. But this hasn't fixed my issue.
But then I tried the rotate-all-axis calibration method and now my compass is much better! Here's what to try:
1. Install GPS Status from the Play Store:
https://play.google.com/store/apps/details?id=com.eclipsim.gpsstatus2
2. Open the app, then bring up the Menu and choose: Tools > Compass calibration
3. Rotate the phone along the 3 axises a couple of times, like in this video:
http://www.youtube.com/watch?v=oNJJPeoG8lQ
4. Press okay and your compass *should* be better
NOTE: I just noticed that when I went to test on another phone to compare (I also have a Nexus One), that my Nitro went out-of-whack again and only after a short while from previous calibration! Another calibration and it's working again, but that sucks that it lost its' bearings so quickly like that.
Give it a try and good luck!

Didn't really work for me. I really think this is a hardware issue. Do you think we should demand some kind of rebate for this or something? I know (its somewhere on the threads) that LG officially acknowledged the problem and have yet to come out for a fix. They are knowingly selling a defected phone.

anybody test the phone with any of the new official software?

After calibration compass works correctly.

For how long? Work after a reboot?
After flashing a new ROM?

Yes, it works after reboot. But calibration will be lost after flashing new ROM. I dont know where its data is stored.

still sucks. all jumpy and not accurate.
I calibrated mine acouple of times yesterday. The compass worked, but it was very sluggish or spun too fast, and unless I put it on a table, wouldn't stop spinning.
I tried today, and it worked but was very slow to catch up to my movements.
Tried some sky map apps, and it just sucks. Same with the augmented reality apps.
wish there was a fix - or we at least new the problem.
thinking I may go back to stock and send it in to telus and see if there is a fix. Anybody have a working compass after a hardware swap? or repair?

The calibration did fix (even after reboot) the compass but I've noticed it takes sometime to settle after starting an application that use the compass.
At first it looks like the infernal spinning madness is about to start over again but after a few spins it stops at the correct position and stay there.
Weird...

[Q] Gyroscope, Accelerometer & Compass Won't Work

So at some random point my Gyroscope, Accelerometer AND compass all stopped working. I first realized web pages weren't changing orientation so I tried turning Smart Rotation on and off. No luck. Auto rotate is turned on. I also tried recalibrating my Gyroscope in the settings and still no luck. Everything from games to the browser and even apps to show info on all 3 of these things will not work and the compass reads North/NW all the time. I can't find a decent app that just says yes/no the gyroscope/accelerometer are/are not working, but I can flip my phone around and move it fast, etc etc and the readings don't change on the apps I have found. I wouldn't think it's a hardware issue unless all 3 of these are on the same part? I'm no too keen on the hardware end so I'm kind of blind, but I wouldn't be posting for help if I didn't try everything I could think of. Any help or suggestions would be incredible!
Oh, and also good to know: I even tried full wipe and changing to the AT&T CleanROM coming from v6? of the Jedi ROM thinking it could just be some random thing I missed... Although I did use Titanium Backup to restore everything... Anyways, I'll try any and all ideas. Thanks in advance!

Edit: btw if you use APEX Launcher, did you enable "lock desktop" option by any chance? Don't know if that keeps your screen from rotating or anything... just a thought!

Okay, I did the number thing and a bunch of different things came up...
"UPC-A
EAN-13
EAN-8
Code 39
Code 128
Interleaved 2 of 5
Codabar
GS1 Databar"
Do I need to do something here? Thanks for the responses!
*UPDATE*
So it must be a software thing. I used the app retrorom posted about and it seems like the compass doesn't work. But the accelerometer and gyroscope work on both the green and red axis but the blue seems to stay in position.. Not sure which is which (x/y/z). Still unsure if this is a software or hardware issue... I'm running Nova Launcher, by the way.

Hmm ok. I just tried the compass feature with ZdeviceTest and when I move the NoteII left to right and up and down I can see all three lines moving. So that seems not normal that your "blue line" on the compass feature doesn't move. Maybe it really is a hardware issue then, I hope not...

[Q] Samsung Galaxy Note 2 Motion Sensor and Gyroscope not working

hi i just recently bought a galaxy note 2 phablet, im very happy with it every thing works perfectly fine, however i did come across a slight problem which is bugging me alot, as i loaded the phone up it shows you all the tutorials and stuff, for panning and zooming in using motion control.... i did not realise the problem before as i was really happy to just get the phone after so long, My motion sensor and gyroscope functions are not working
i have tried everything from factory reset to restarting , taking the battery out and putting it back in, has anyone stumbled upon this problem, and is there a solution to this problem, whether this is a software glitch/problem or a hardware issue. if anyone can help me please and thanks in advance

hi thank you for the quick reply, i had a look at what you asked me to do and i did manage to find all the settings, however it looks to me everything is working apart from the light sensor one, all the other settings came up as a PASS apart from the light sensor which came as level 0, which i dont know what that means, while i was on the sensor screen i swiped my hand across the sensor and the screen shifted colour from white to yellow, which is a good indication that it is working , however i went back on the operating system and tried the palm swipe and it did not work, niether did the quick glance, and the pan to zoom features are not working either, i did test the gyrocope settings and it came out as a PASS too, could you explain maybe why this may be happening and what does the level 0 on the light sensor option means, please and thank you , i really do appreciate it.

Lavel 0 says to all phones I have tried including mine. As long as the LUX changes it is working.
Now for your primary problem try to recalibrate gyroscope.
Do it by going settings-motion-advanced settings-gyroscope calibration.
If that does not help try clearing cache in recovery.
If that does not help then backup and try reflashing your rom.

Hello in response to your issues with the motion sensor. Have you installed a screen protector on your note 2? i noticed that after installing the screen protector on my Note 2 some of the motion actions did not work properly. So if you do have one on remove it and see if that corrects the issue. :good:

Useful help.
This was a very Useful thread, thanks. I've done the tests and came up vitha a fail when i tried my motion sensor. Is it likely to be broken? I'm going to reset to factory settings and pull of my screenprotector and se what happens before i do anything else. Is there anyone out there who has replaced the motion sensor? Is it soldered to the main board? Hard to replace?
Thanks beforehand. Tommie.

i thnk my sensor is nt wrkin... when i do the test, d color is alredy green nd isnt changin nd is vibratin continuosly?? is it broken or somthng lyk dat??

Samsung Galaxy Note 2 Motion Sensor and Gyroscope not working
hi my samsung note 2 was working well for last 2 years bur recenrtly its motion sensor has stopped working.
i have checked all settings, it isnt working at all..
gyroscope and motionsensor tests are fail on checking. please help me, what to do?

I have had the exact same issue. The only way to fix it is to get the whole motherboard replaced. I went into Samsung store and they said that. Issue here is that it costs £145 to replace the main board. The sensors are on the main board itself and that is why it costs a lot to fix. I've been using my Note 2 with no gyroscope for a few months now, going to buy a new phone. Rather buy a brand new phone than get it fixed

just loosen the screw nearest to the microsd card. motion sensor is under it. it work on my phone.

gyroscope sensor
Hi,
my gyroscope is burned and i buy it and now i opened my phone and i don't know how to replace it. Any help is welcome...

Yeahhh!!!
You are a Hero! I tried nearly everythink since January 2016! I took the screw out, shut down my phone, put it into download mode and pull the battery out.
Im not shure if a restart would do it alone, i did all to be shure. And it now works again. My srew was magnetized! Maybe that was the reason or the chip has
a loosen contact.
Up to now it works great! I thought my sensor was dead.

G sensor not working

Please help...g sensor on my One X is not working....
I have tried calibrating G sensor in safe mode, rebooting, factory reset, reverting back to stock but nothing seems to be working.

You seem to have one of the HOXs with the Invensense sensors inside, controlled by a Invensense MPU 3050 chip. Newer HOXs use Panasonic sensors if I'm not mistaken.
You won't like this, but there's really nothing you can do. It's not exactly a hardware defect, it's caused by a race condition. Apparently the MPU 3050 has this funny little quirk where it keeps some electronic charge even when the device is powered off, and when it powers back on too quickly the chip doesn't properly initialize, causing the sensors to be present for the system (you can check this with Elixir, it's free on the market, it will show all your sensors) but non functioning.
The only "solution" I found to this was in a forum for Acer A500 owners (same MPU in those things). Switch off all orientation control and whatnot, like auto-rotate etc, then turn your phone off entirely and let it sit for at least 5 minutes, maybe 10 just to make sure. This is more of a hit and miss approach, but definitely worth a shot.

I have the same problem. Tried flashing diffrent kernels and roms, reverted to stock with nandroid backup and with ruu files. Rebooting in safe mode, calibrating. Nothing helps. It seems the only solution is like AcoQ said, turn off hox and turn it on after few minutes. I do not have warranty any more so no replacement from HTC... It happend to me yesterday after flashing new rom and kernel. Now after restart sonsors are dead, another restart and all of them work, restart - dead, restart - work and so on

Don't use any power saving app. Even the power save mode in stock rom. Delete all the power saving apps and cache files from app settings. and restart. Hope start works!

I also had problems with g sensor. Nothing seemed to work. Reverted to stock. Then tried this solution I found.
Reboot the phone with power + volume up. Hold them.
Let it reboot three times (the solution showed one time, but it only worked for me after a couple).
Now release the power button and hold the volume up during the whole boot sequence.
I don't know what the exact physics is behind it, but it should reset some things. This was the only solution which helped, and actually worked for me after trying all the other things
Good luck

even m suffering from same prob
my auto rotate stops working all of a sudden
i was on arhd 21
please help tried reflashing RUU but no help

Now with Sense 5 ROMs,Camera force closes for devices which are having this sensor issue. Seems camera drivers needs gyroscope to work properly.
Will roll back to CM10.2 nightlies. Atleast the problem isn't noticeble in AOSP ROMs.

I have the same problem and I am using ARHD 32.2 please help!! :crying:

It worked for my HTC One X in a moment,and it works perfectly even after you powerdown device
Solution is the best i found in this 5 days of horror with my HTC One X camera and sensors not working!
Now it works all perfect!!

I had the same problem while running viperX 4.0.6 and tried all the various hit and miss techniques and they would restore the sensors and camera for at best a week. Tried flashing different roms too. Then I decided to try a KitKat rom and went with AOSB Project http://forum.xda-developers.com/showthread.php?t=2678836 and I have not had a single fault since.
I'm not sure if it had something to do with the KK recovery, ROM, combination of both or jst coincidence?

Dear Friend,
Don't try flashing or Installing ROMs. Its an unknown error. You can have the solution I mentioned below. Try this friend.
Its an unknown error of HTC one X. I also discovered it. When it was ICS 4.0.3 it was very good. After updating to 4.2.2 Jelly Bean the problem happened. Please follow my instruction that may help you. When you will find your G sensor calibration stopped.
1. Just Disable Auto rotation from Setting--> Display Gestures & Buttons. Or you can disable your Auto Rotation from anywhere you can find in your device setting. Just Uncheck the Auto Rotation.
2. Power Off your HTC one X. Remember No Restart. Just Power Off.
3. Leave it for 10 minutes or 20 Minutes.
4. Now restart and see what is happening. Your G sensor is working or not. You may go to Camera you will find it is Auto rotating. Leave your Auto rotation Setting. Just open the Camera and see Auto rotation is working or not.
5. If it is OK now you can check Auto rotation if you want to open browser in Landscape Mode.
6. If you failed or you have the same problem you just Go to the Power and Uncheck Fast boot and again follow from number 1.
I am confident because that really worked for me. I don't know it will work for you or not. I already told you this is such an unknown Error. May be a conflicting issue with HTC one X tegra Hardware to the JB 4.2.2 Android.
Thank you.

I am confident because that really worked for me. I don't know it will work for you or not. I already told you this is such an unknown Error. May be a conflicting issue with HTC one X tegra Hardware to the JB 4.2.2 Android.
Thank you.

Dear Friend,
Don't try flashing or Installing ROMs. Its an unknown error. You can have the solution I mentioned below. Try this friend.
Its an unknown error of HTC one X. I also discovered it. When it was ICS 4.0.3 it was very good. After updating to 4.2.2 Jelly Bean the problem happened. Please follow my instruction that may help you. When you will find your G sensor calibration stopped.
1. Just Disable Auto rotation from Setting--> Display Gestures & Buttons. Or you can disable your Auto Rotation from anywhere you can find in your device setting. Just Uncheck the Auto Rotation.
2. Power Off your HTC one X. Remember No Restart. Just Power Off.
3. Leave it for 10 minutes or 20 Minutes.
4. Now restart and see what is happening. Your G sensor is working or not. You may go to Camera you will find it is Auto rotating. Leave your Auto rotation Setting. Just open the Camera and see Auto rotation is working or not.
5. If it is OK now you can check Auto rotation if you want to open browser in Landscape Mode.
6. If you failed or you have the same problem you just Go to the Power and Uncheck Fast boot and again follow from number 1.

Dear Friend,
Don't be upset. Just understand. It's the fault of HTC itself that they did not care about this.
If you failed then just do it again and again. It is like if your problem is solved you can test it again. That means if your G sensor is back you can restart your phone and you will see your G sensor is gone again. It is like restart... G sensor is OK now .. again restart G sensor is gone...!!! again restart it will come back or may not come back. Again you need to restart. That's it. Restart your phone holding the power button down.. no release button..wait for the HTC logo screen. you should restart like this. Not restart from the HTC screen touch. Just hold down the power button and wait for the HTC Logo screen. The restart interval should be 10 to 20 min. Just do it. I am confirm your G sensor will be OK. Believe me.

Dear Friend,
No reboot!!!!!! Just power Off your phone for 10 to 20 min. No reboot!!!
Please try it several times if your G sensor is not fixed. At first I tried it for several times when I did not get my G sensor OK. Oh. I have a mistake. You need to power off the phone. Not restart. Oh dear I am sorry. You need to power off your phone for 10 to 20 min. Wait for 10 to 20 min and then Power on your phone. You will see your G sensor is working now. The previous post I just want to make you sure that If your G sensor is OK and if you again restart your phone you will see your G sensor is Gone again. So you need to Power Off your phone again for 10 to 20 min. No Restart. Just power Off. It was a great mistake to my previous post and so I am really sorry. It will be Power OFF your phone for 10 to 20 min. Then power ON your phone. If you not Get back your G sensor OK then you need power off your phone again for 10 to 20 min. You will get back your G sensor I am confident. Because My HTC one X also doing this ****. My G sensor is OK now. If I restart my phone for any reason My G sensor gets stop totally and receive no Calibration. It says calibration Stopped. So I just do power Off my phone for 10 to 20 min and then I switch ON my phone. The I see that My G sensor is OK. Even my calibration also works. If after switching ON my phone if I get that My G sensor is not OK then I just power off my Phone for another 10 to 20 min and then I Power on my Phone and I find that My G sensor is OK. It really happens. And I found many posts about this and even I flashed my Phone and nothing made my G sensor OK. Its the unknown software fault that HTC did not solve it for HTC one X. They will not do I think. Even you will not be updated above to 4.2.2. Again I am telling you just switch OFF your phone for 10 to 20 Min. Then switch ON your phone. If you not get G sensor Back then again switch OFF your phone for another 10 to 20 min. You will definitely get back your G sensor. Again if you restart your phone for any reason you may find that your G sensor is gone again. So again you need to switch OFF your phone for 10 -20 min and switch ON your phone. If you not get again do it. You will get back your G sensor. But Actually how many times you need to do it also unknown. If I find My G sensor is not OK after 20 min stopped I just do it again. Maximum second time it solved my G sensor. It may take longer. I sometimes have my problem solved in a single try or second time. It may take longer for you or you may have this solved with a single try.

I would like to share my experience about the problem with the sensors of the HTC One X.
I use HTC One X International version

Currently use ARHD 33.1 (Android 4.2.2) + stock kernel.
I tried all the methods that I could find on the web.
1. I tried to change any ROMs based on Sense 4, Sense 5, Cyanogenmod and any kernels for them. It did not help. The sensors are still not recognized.
2. I tried to discharge the battery completely and it did not help. The sensors are still not recognized.
3. I tried to change all firmwares on 401 base (3.14.401.31, 3.18.401.1, 3.20.401.1, 4.18.401.2, 4.18.401.3, 4.18.401.4) and it did not help. The sensors are still not recognized.
4. I tried to install RUU_Endeavor_U_JB_45_S_HTC_Europe_3.14.401.31_R_Ra dio_5.1204.162.29_release_302015_signed and it did not help. The sensors are still not recognized.
5. I tried to restart in safe mode after disabling fastboot from power settings and recalibration G-Sensor. Then rebooted in normal mode and recalibrated again and it did not help. The sensors are still not recognized.
6. I tried a factory reset and it did not help. The sensors are still not recognized.
7. I tried to kill all apps in task manager and it did not help. The sensors are still not recognized.
8. I tried to power off after disabling fastboot and orientation from power settings. Interval waited 10-20 minutes and it did not help. The sensors are still not recognized.
9. Try using FLAC formats as they are huge in size and it did not help. The sensors are still not recognized.
10. The only way that I can come back to life sensors is to use the program from Google Play - Stability Test. Run of classic and wait until the temperature rises to 44-45 degrees Celsius. Then immediately reboot phone and sensors are activated (by this method have a 95% success rate), but after restart or turn off the phone after disabling fastboot the sensors are still not recognized. The most interesting thing is that after this procedure if you do not reboot or shut down the phone all sensors work properly.
If someone has tried something different and has helped him to return sensors to life even after restart can share.
This is for now. If you learn some more valuable information will be shared here and wherever raise the issue of this problem.
I hope to come away with making a decision that will help us all to deal with this problem.
Greetings to all.

The 10 is the only method that works now for me.
Before, the trick of power off and power on had worked but does not work anymore.
Is annoying, you know that if you restart the phone you run out sensors...
