Hi, I have a problem with the compass on my UMI zero. When I use google maps or any compass app the direction pointed by the arrow is always the same whatever direction i rotate my smartphone at. Only sometimes it points in the right direction but slowly rotating to the same wrong one. What's going on? I tried to install different ROM but the problem was never solved, and at the beginning it was working, i cannot say flawlessly but at least acceptably.
Compass problem
i was facing the same issues as you are with UMI Zero's compass especially on its stock firmware (update 3.10), but i went ahead and got the rom from this thread
http://forum.xda-developers.com/and...-miumizero-miuiv6-umi-zero-t3050090?nocache=1
and installed the firmware available on it.
i also made sure that all GPS settings were on before using the compass because without it (try using it with the data on for the first few trys), it kept telling me to wave the phone in the shape of an 8 to recalibrate it. it works now much better than before but it is still not completely accurate. i think the problem is within the hardware rather than the software.
Hi there my GPS was very quick under Kitkat with immediate fix and perfect compass. Under Stock Lollipop it still worked well enough. Since I use [5.0.2][D802] Google Edition 1.5 my compass doesn't work anymore and GPS doesn't fix at all or takes 10 minutes shows wrong location and looses signal again
I don't know whether the problem is the ROM or that my phone fell down hundreds of times.
Anyway I already tried the apps fasterGPS, gpsStatus and TopNTP without success and did the cardboard mod hardware wise.
Please help I want to play Pokemon Go
Has anyone had problems with the gyroscope in vr applications?
The compass works very slow. And vr applications are not able to move the screen with the movement of the phone.
Any way to calibrate the compass or gyroscope?. Anyone else has happened?

i dont use vr, but a lot gps navigacion,i install gps esencial from play store and its giving me under 20 ft precision mostli al the time, but google maps its get lost a lot, somtimes an error of 1000 to 3000 ft. im thinking is software problem not hardware. other navigators go beter but still get lost somtime. my motorola G first generacion is a crack, never lost.
There is a known issue with the gyroscope being non functional . There is a fix in the latest OTA formware update which came out last night. I've just updated and thingsseem ok.

Make sure you are on the 20161215 firmware release and retest.
Hi, anybody can help me, my yd201 proximity sensor not working, i did everything flashing all rom on the forum to try fix this but it still doesn't work. (from 4.+ to the latest MM) with all firmware. i just trying full unroot my phone on root apps then wanna clean system apps using twrp so am try deleting root forder from latest twrp to clean everything, now proximity sensor not working what ever i do rotate, calling, and the biggest problem is back screen is not working too,. download sensor test from the market is working too(device sensor hardware not support on this phone)

Open the phone dialer and dial *#*#4636#*#* , if it doesn't work the first time try the code again and it should open the hidden testing menu, choose device test and you can manually test all the phones sensors to confirm if the proximity sensor is working or not. I had a s7 that did the same thing, the proximity sensor just quit working one day and I confirmed it wasn't working with this method. Good luck.
same result, not working too.
maybe problem is from hardware,
any idea on how to fix it, just something like using xposed or what?

I just dealt with it, sometimes it would work and sometimes it wouldn't. There's an app on the play store that you can use for screen rotation, I ended up using that when I absolutely needed rotate the screen.
i dont care about rotation screen.. i just want the back screen working normally, if tap transfer button on color display it won't open it on epd screen when i rotate the phone..
I don't know if it happened the same with you, I own a YD206 so I am not sure how YD201 behaves, but there's a problem with proximity sensor that makes it working all the time, I have wrote a comment about it and will try to contact Yota about this, meanwhile it would be important for people that are not aware of this problem because is such a faint light to actually confirm if the same is happening to them, YD201 or YD206:
I discovered that I also have this problem, I was with the wrong radio, had to flash the Chinese radio and it suddenly appeared, this is what I have found I have an YD206, so I wonder how the YD201 behaves:
On YD206:
With wrong radio. radio (Russia xx versions) on YD206 , in KitKat or Lollipop ROMs the proximity sensor is OFF by default BUT, as soon you turn ON an app that uses it, it won't turn off again, it keeps blinking even if you force kill the app that started. However it will turn off if the screen is off, after 5 seconds after. Also it's important to acknowledge that 2G only with this radios fails. On Lollipop Wifi won't turn off automatically, just manually.
YD206 With the correct radio. radio S01_003_3034_CN1_M05 2G 3G (UMTS) and 4G (LTE) all work and with better reception, but as soon the screen is ON, the proximity sensor starts working, does not matter what app you have open, when you turn OFF the screen the proximity sensor will turn OFF in about 5 seconds. If you are using the EPD screen the proximity sensor will turn OFF faster than 5 seconds, but as soon you touch the EPD it will turn ON for 3 seconds or so. On Lollipop Wifi won't turn off automatically, just manually.
So the problem acts differently when you flash a different radio, I am not sure where's the bug comes from, but it seems there's also a bug with YotaRom. There's a Xposed module to disable proximity sensor in specific apps, I haven't tried that, I also would like to know how this behaves with the Marshmallow Beta.
(For the ones that are not aware of this problem, keep in mind that to see this problem you need to be on a dark place to see the very faint red light of the proximity sensor.)
Best regards,

Hi,
I have been using P9 lite (model L31) for the past few months and found that the compass has some issues. Even if I calibrate the compass using figure 8, it does not stick to one point. For example, if I use google maps walking navigation, the map keeps on rotating so much that its hard to find the actual direction. Though the same does not happen in car navigation mode.
I have experienced the same thing in other apps as well. The compass does not stick to one position and it keeps on rotating.
Does anyone experienced this issue?

Even granting location access to the default compass app of the phone does not help. Does anyone has any clue why is it behaving like this?
Same problem on a L21.
Compass used to work fine, but since a few weeks ago it does not point to magnetic N... not even to a point with a certain deviation (if I rotate the phone, the "north" also rotates with it).
My good old N8-00 compass still works fine...
After A LOT of 8 shaped calibrations (with and without GPS enabled), the compass seems to work again...
