Hi All,
Have you tried compass and level tools among ZTE tools? First of all I waved 8 I don't know how many times till it was "calibrated". If it really was. I have doubts because result is far from the accurate. Secondly I tried level tool and spirit level is not needed to say that it shows wrong values. Thirdly camera in manual mod displays a spirit level which also incorrect. Do you have bad or good experiences with these tools? Can anyone know how can level be calibrated?
I have the same problem on my Axon 7. The Y axis is about 5 degrees off.
I can't find any way how to calibrate without root. Did you find a solution or can anyone else help?
Hi,
It looks that compass works correctly more or less. Regarding spirit level. No I haven't got permanent solution. All program can calibrate level. Some of them can store calibration result but of course it isn't effective generally. I tested all sensors with different programs and they seem good. I don't have other A7 so I can compare the values to other brands. Try GPS Status and Toolbox to test sensors.
I worry a bit that VR won't work correctly but I think it will have own calibration method.

Hi note 4 users,
I chanced upon a test that dial #0# (forget the exact number) which bring you to a test screen where you can check the screen, color, camera all sort of tests...
I have it all pass except for a test in HRM which is HRM EOL Sensor test.
I had quite a few selections which is fail granting the overall test Failed.
P_ir ac level
dc level
d_ir dc level
p_red ac level
p_red dc level
f_red dc level
cloud uv ratio
i had no idea referring to which hardware or software. Is it infrared sensor?
While using note 4 i didnt notice any weird stuff going on. Is still pretty smooth in performance and displaying & sound good. Except for firefox app random lag or crash error. All is good.
Any answer? thanks.

Hi, I think it is the Heart Rate Monitor sensor in the back of the phone.
it is the IR blaster (remote controller)
Hi,
I am working on an app which requires the watch compass. While it seems to work as expected on Samsung Gear Live I get nothing than problems when running it on Sony SWR50 Smartwatch. Same happens with all tested apps from Play Store. There are situations where the compass works as should, but just minutes later it displays just crap or the value displayed is almost frozen. And it got even more worse from firmware version 4.4W2 to 5.0.1. No idea about behaviour of the other watch models actually available.
For getting a more clear view on usability of watch compasses in general I have written a little app named CompassTest which implements all three methods of reading the compass which I am aware of. All three results will be displayed together on one screen:
- sensor TYPE_ORIENTATION (no longer recommended for new apps)
- sensor TYPE_ROTATION_VECTOR
- sensors TYPE_ACCELEROMETER und TYPE_MAGNETIC_FIELD
If you want to support me then please install CompassTest onto your phone, start the app on your watch and check the results being displayed for plausability. All three values should be almost the same, the flicker on the 3rd value is normal as there is no dampening built in.
Please also calibrate your sensors by moving the watch several times in shape of an 8 and in all three axis.
Check the displayed results against a normal compass or the north direction if you know it from elsewhere.
Please report your results here with your watch model and short description of behaviour.
Thank you in advance,
Gerd
Hi,
I am very disappointed by the compass quality of my i9515 S4 value edition, because no matter what I do, whatever direction I turn my phone to, the compass only changes by about 2 to 10 degree, and has the wrong direction most of the time.
This is Android 5 stock ROM.
I have made a video to illustrate the behaviour.
http://youtu.be/g6jcmLf8L3A
What I have tried:
- enter the calibration dialing *#0*#, which passes, but does not change anything
- reboot
- try different compass apps
- switch of energy safe mode
Nothing helps. Is this a general bug with the i9515, or is my compass sensor broken?
I wouldn't trust my life in the compass on those phones. I'd rather look for moss on the trees )
Anyone have anything to offer on compass calibration?
I noticed the compass was off in a couple map apps and compass app, always with the same bias (about 18-20 degrees CCW).
Searching Play Store for "calibrate compass", I found a decent compass app (RHB) with a calibrate mode, instructing to do the figure-8 to calibrate. Didn't really work, would not indicate calibration complete.
Found a different app (GPS Status) with a calibrate compass mode that has instructions on how to do it correctly: Rotate 1-2 times around each axis (3 axes) in calibrate mode. This works. Turns out this 3-axis calibration also works for the other compass app too - using the 3-axis calibration method, it indicates " complete " and the compass is calibrated.
I'm wondering if this is something that will have to be done again after every reboot, and/or every time I use something that uses the built-in compass hardware (magnetometer). Or does this in-app calibration calibrate in some way that stores calibration offsets in a lower-level place (OS, hardware, ?) so that calibration persists across reboots and is always there for any app. After rebooting and letting the phone sit overnight, the calibration may have drifted a few degrees, but I wasn't sure because I checked it in a different location.
Interestingly, another recently released Android phone (Kyocera Hydro Wave) that I checked had the exact same (uncalibrated) compass bias as the XT1575, off by the same 18-20 degrees CCW. Makes me wonder if they both use the same magnetometer component(s), from the same source.
Any info would be appreciated...
Gps status & toolbox is what I use on all my families devices and works perfect,. Once I calibrate my compass from then on when I open gps status & toolbox in just a lil bit it will auto set north. Great app called gps status & toolbox in play store and if you don't like ads get the pro key...

Hey all,
Recently got this phone, and I discovered it doesn't have a gyroscope (Kinda took that for granted, should have researched before purchase).
I like to do VR stuff once in a while, so I found the option of using the Xposed module VirtualSensor.
It seems to work, only it's horribly inaccurate. I understand that combining the accelerometer with the compass/magnetometer will never be as accurate as a gyroscope, but I don't think it should be this bad.
I looked further into it, and it appears that my magnetometer is not as accurate as I would like it to be. I found multiple sources that don't even list the compass/magnetometer as a real sensor, is this true?
Anyway, using Sensor Kinetics (app) I monitored the magnetometer (it shows the same behavior using different apps). I wanted to post screenshots but as a new member apparently I can't.
I've calibrated my sensor by using the 8-motion and I measured at different locations, but the z-axis is always weird. There's some sort of disturbance in a pattern, it could be hardware or software. Every second or so there's a significant peak in the z-axis, jumping from -43 microT to -30 microT or even higher. (The magnitude of the graph is of course orientation dependent, but the accuracy shouldn't be this bad). The peaks in the z-axis match up with sudden yanks while using VirtualSensor (my accelerometer is stable).
Could anybody with a P9 Lite please confirm if they have a similar disturbance on their magnetic sensor as well, or do I have a faulty phone?
