GT-I9195 compass not working properly, possibly magnetometer issue - Galaxy S 4 Mini Q&A, Help & Troubleshooting

Hi everyone. Compass is stuck in my s4 mini. From sensor test (*#0*# then sensors) I can see this (see attachment). It seems like magnetometer is not calibrated. Any way to calibrate it (apart from usual methods like 8 figure or rotate phone around tre axis since I already tried them and they didnt worked) or reset it to stock values? Tried factory reset too.
thanks a lot guys.. I really need help, It may be an hardware issue but I want to try everything via software before send it to sammy

Please help guys, tried wipe cache and dalvik cache too. Send phone to samsung is the last thing I want to do due to my knox 0x1.

I have the same problem. I have tried to rotate phone along his three axis, while in sensor screen. Phone vibrate and light green during this operation and "need calibration " disappeared... Now only number "3" is displayed.

Unfortunately, I tried calibration in sensor screen too but nothing happens. Always "need for calibration 0".

Solved reflashing the whole firmware with odin... calibration now works.

Found out that the problem was the kernel. As soon as I flash a kernel different from the stock one, compass get stuck. On stock rom and JB at least... be careful.

[Q] DHD Proximity sensor

Hey all,
About a year ago I got a new DHD everything was working fine. I rooted it (using visionary), tried cyanogen mod, went back to the original sense/frayo backup and finally installed a new kernel (Buzz)...
After that my proximity sensor stopped working, I kind of just put up with it because I was busy at uni, I just got used to manually turning my screen off. I thought it was something to do with the kernel and/or backup I was running. Since then I have installed Android Revolution 6.3.1 with new kernel and radio and thought it might just start working again but it hasn't...
My question then is:
Could I have done something to affect it while flashing/rooting e.t.c?
Is there any way I can check?
Is it likely to be a hardware failure? (the phone was less than a month old when it stopped working)
oh and I have tried Proximity Re-calibrator and it dose nothing (Unless it doesn't work with ARHD 6.3.1).
Thank you for your time.
This is a common problem. It's in the faq of the ARHD rom and the answer is:

I have tried and tried Proximity Sensor Recalibrator.... no change.
What did you do in the app? Did you also read some of the posts below the first posts on how to use it? I mean, a lot of people have already posted there that they have all sorts of problems with the sensor. If there is really nothing that helps you I would try flashing at least one more time with wiping everything (btw, did you do a full wipe before coming to arhd?)
Yes used the super wipe as suggested.
I've been holding my finger over the sensor and increasing the thresholds, attempting to get a change, all combinations of the sliders and it just says 'far' continually.
Thanks for replying, sorry if its just that I'm just using the program incorrectly...
Full wipe and re-flash tried everything in Proximity Sensor Recalibrator nothing changes...

Broken Accelerometer and gyroscope

I noticed that for some unknown reason my accelerometer and gyroscope just stopped working. I have managed to fix it and thought I would just give my story in case anyone else has this problem.
I did drop my phone but not badly and it landed on a relatively soft floor.
I tried factory resetting battery, pull, and full wipe and reinstall of custom roms. NONE of these options worked.
The only thing that managed to reset it was doing an update through Odin with an official samsung rom 4.4 that I downloaded from samsung
http://www.sammobile.com/firmwares/1/
This was the only way to reset the accelerometer and gyroscope sensors, it also updated the baseband version to a kitkat 4.4 compatible one so I suspect if I do go back to the custom roms again (I was on Carbon Rom) this baseband update will stay with the device.
Anyway it is all working now and I am very happy the updated samsung rom in much much better and more debugged than the stock rom that it had when I got it so I think I am going to try it out for a while and see how it goes I will undoubtedly go back to custom roms but in terms of recovery it is nice to know that a flash of the official rom will truely and fully reset and calibrate the sensors like the gyroscope and accelerometer.
cheers

Sensors Broken after ROM Change

So, i'm completely lost. I was playing around with ROMs and mods (the RAM build.prop, for example), and now all my phone's sensors seem to be stuck.
I have reflashed back to completely stock ROM, taken official sprint update. Tried modded ROM, done factory resets, cleared/wiped everything, and still the issue persists.
It would appear my Gyroscope, Accelerometer, Proximity Sensor, and Compass are all not responding at all.
Right now i'm on rooted stock AOJ6.
Does anyone have any ideas? Maybe a corrupted sensor properties file or something similar like that? I'm completely at a loss.
Any help is appreciated.
Guys, it fixed itself. I booted into safe mode, restarted and all the sensors are working again.
I doubt it had anything to do with safe mode, as the sensors weren't working in safe mode.
I have no idea what could have done it. I wish I had a real answer for you.

Gyroscope and other sensors not working after recent updates. HELP!

Thank you for clicking on the thread.
I've loved my Zenfone 2 for a while now. I have the 64gb 1080p model. It was a well priced powerful phone for what I wanted.
However, I recently received an asus software update that completely borked the Gyroscope and some other sensors. I have read about similar issues online and testing the sensors reveals that they're not working.
Does anyone know how I can fix this? I have been unsuccessful in trying to install CyanogenMod13 or even TWRP/CWM. I rooted my phone and the bootloader is unlocked (white backscreen upon loading).
It seems as though ASUS doesn't want to fix this, would upgrading to a custom ROM provide firmware that would properly recognize and use the gyroscope as input?
I've tried wiping the system cache in the stock recovery, resetting to factory new and everything to no avail.
I am willing to "tip" or "pay" for someone's time if they can help me as I cannot auto-rotate or use any applications requiring certain sensors.
Thanks for your time.
I've upgraded to CM13 successfully now and the gyroscope is still not even recognized in Sensor applications. Is it hardware?
solution?
