Huawei P20 lite none of sensors are working (magnetometer, gyroscope, accelerometer,...) - Huawei P20 Lite Questions & Answers

Hi,
i am repairing phones and i recently repaired destroyed Huawei P20 lite. After some testing i found out that the compas is stucked at one direction, same with gyroscope (stucked on 9degrees).
I dont know if its a hardware or software issue, all apps are saying that the sensors arent plugged in. I didnt found anyone with this problem.
Where are these sensors located on board? Is there any way to check their functionality?
Thanks in advance for all the answers, sorry if its miss categorized, never posted something there

It looks like a system error. I would try factory reset in stock Recovery and update phone by flashing the service ROM via dload method, or via Wi-fi & eRecovery.

So i downloaded sw from androidhost.ru (different than before) and its still same, still stucked at north and 9degrees.

Hard to say. The sensors work depending on each other (especially the accelerometer and gyroscope), it is enough if one is damaged and almost nothing works. For example, compass needs a functional geomagnetic sensor.
Compass doesn't work in google maps either? (just to be sure...)

no, it doesnt. Where are they located on board? Couldnt find that online. Any way to check them from hw side?

By the way, that screen from AIDA is missing some other sensors - proximity, light sensor... I didn't notice it before. I don't have a P20 lite anymore, I made a screenshot on a Mate 10 lite, jfyi:
Some sensors can be tested via the built-in MMI tests, dial on the phone
*#*#2845#*#*
there are other variants:
28465
2847
2846
You can move around the test using the buttons Power and Vol Down.
What is your current full build number (Settings > About phone)?

9.1.0.132(C432E5R1P7) - i noticed that is all sw, now im trying bypass another p20 lite with C782 with safe mode files from C432, i can try update this one with C782

I forgot to say, dont know if it matters, but both of them are google frp bypassed via dload safe mode (already tried flashing new rom, but C432 no C782
edit: not both of them, the second is that im trying to bypass now, but that with not working sensor is already bypassed

---

you cannot install C782 on C432, you would have to change oeminfo C432 to C782 first.

Have you tried update phone via wi-fi & eRecovery?

I assume that it should download sw automaticaly from huawei and it is not using sdcard or otg to update, but its saying getting package info failed. Phone is half charged, placed next to router connected to power.

When even the built-in test can't find any sensor, I really don't know what happened to the phone. Something should appear via ADB, try command
adb shell dumpsys sensorservice
Try downgrading to A8 via
HiSuite, it should work on 9.1.0.132.

One last chance (if it's a SW problem, it probably is) -
1. install via dload method 8.0.0.126 and get bootloader unlock code using dc-unlocker or hcu-client services (4euros)
Link
There is also a free "potatonv" method, but it might not be the best idea in your case. But it's your choice.
2. Install TWRP 3.2.1. "pretoriano80"
Link
3. In TWRP perform "format data" , reboot into TWRP again, wipe Data, System, Dalvik/Art cache, go back in TWRP menu and flash Hurupdater with 8.0.0.344
Reboot Recovery and perform Factory reset.
HOWTO
But I'm not sure if it will solve your problem, so decide for yourself.
By the way, where are you from if I may ask?

Sorry for delay, i am from Czech Republic.

should i flash just the Hurupdater+miui 8.0.0.344 or add the files that you sended to the guy you are reffering to in HOWTO?
