Honor 10 lite sensors not working after screen replacement - Honor 10 Questions & Answers

Hi all,
First post here! So I replaced the screen on my honor 10 lite the other day, as well as the charging/headphone jack pcb and battery - all working fine aside from now none of the sensors work. So accelerometer, gyro, screen brightness (auto option no longer there in phone brightness settings) and proximity are not working. I know underneath the main motherboard there's a 'sensor board' small pcb - does this handle the function of all the sensors? A new board looks inexpensive enough - i don't see how I could have possibly damaged the board but if replacing it will fix it that would be easy, just don't want to spend more money on repairing this phone if I don't need to.
Appreciate if anyone with any insight could help! Thanks!

[Q] Proximity sensor problems

Hi,
My gx2 was running cm10 and everything was working fine up until recently when my lcd screen broke.
So I ordered a new one and replaced the broken one, the repair has gone well , also the screen was good. Except there was a problem with the proximity sensor, when i tried to make a call the screen would go black and not switch on again, the only thing I could do was to take out the battery.
So I thought maybe I damaged the proximity sensor somehow while replacing the screen, so I bought a new sensor. The same Problem.
So I thought maybe it was firmware related even though I did not change the firmware and before the screen broke everything was working fine.
I flashed a stock rom, again everything went well , phone was working except the same problem with the proximity sensor.
Anyone know what that could be? Could I have damaged the motherboard somehow, even if that is unlikely because I was always extra careful and patient.

1. You should check if the sensor is really damaged. You can use e.g. Android Sensors app from Play store.
2. If it is broken, then try to disable it in ROM settings. I think there is at least an option in phone/dialer settings.
Maybe that can help.
Good luck !

I know how to disable the sensor, when I disable it calling works, but I want the sensor working . The thing is I thought I damaged it while replacing the screen, so I bought a new sensor, but the problem is still there.
android sensor box shows me a value of 0,0
typing in *#0*# and then "sensors" : the screen is always green an the phone is vibrating PROXIMITY: 13
the phonetester app shows Proximity sensor :near
I just figured something out.
The proximity sensor works when I hold the phone against a light source, when i do the *#0*# test and hold it against the light, the screen turns to white and the sensor works as it should( when i hold my hand near it, screen switches green and phone vibrates) , but only as long as it is near the light source.
Could the sensor just not be calibrated correctly? Is there a way to calibrate it?
than you

[Q] Proximity sensor problem !

Hello to all...again !!
Recently, i broke the digitizer flex cable and the antenna cable connector so i had to
replace both of them. I did. Antenna works great, digitizer works great..the only problem
is the proximity sensor.
I have disassembled the device several times and if i'm not mistaken the proximity sensor
is on the digitizer's ribbon cable. Is that correct?
Anyway, everytime i make a call, the screen goes black and can't turn it on. No way to NORMALLY turn it on.
the only way i've found that turns on the screen, is if i put the sensor in front of a light i.e a lamp.
Furthermore, when i go in the service menu ( *#*#7378423#*#* ) and do the proximity switch test it defaults to on
when i think it should default to off (because at the time i'm starting the test, there's no obstacle in front of the proximity sensor).
when i move the sensor in front of a light, the test gives me a sound and the value changes from on to off.
So i'm thinking that there is nothing wrong with the hardware. They didn't send me a flawed digitizer, did they ?
Plus, is there any config file or driver responsible for that sensor ?
Also, i searched xda and found this http://www.youtube.com/watch?v=uMk1S90MjbY for motorola defy. Is there
any workaround like this for the neo v?
Thank you very much for your time and assistance.
bump?
The proximity sensor is on the right corner, between front camera and the right corner.
Check again the position of the sensors beneath those two black piece of plastic.
The items are, from the left to right:
- speaker;
- light sensor;
- front camera;
- two viewer for the proximity sensor.
@ciubexx
thank you for your answer.
I checked the sensors and are correctly positioned but the problem persists.
Again, if i put the device under light the sensor seems to work.
Also, i've downloaded "proximity sensor finder" from google play and it seems like
the sensor is constantly covered. I did the test without the front housing and the same
happened again.
Also, i have a problem with the earphone. When the front housing is attached the volume is
very low but when removed, the volume is normal again. What could that be?
Thanks again.
edit: everything solved. disabled the sensor and removed earphone's cover from front housing.

Bringing this thead up again because I am having the same issue, Proximity sensor set to near all the time... could it be badly placed? I was ever so careful to get it millimetrically perfect..
something must be causing the sensor to read an input all the time. Ever considered there could be some dust below the glass? Try and see what happens when you take the screen assembly away from the sensor. Another cause would be a deffective part (bad ribbon/flex components).
Thank good lord I managed to buy a genuine Sony flex ribbon

Xperia Mini Pro Sk17i ambiance light sensor disable/broken?

Hi out of the blue my Xperia Mini Pro Sk17i ambiance light sensor is either disable or broken ,
when i open service menu by dialing *#*#7378423#*#* , ambiance light sensor just show value = 0, i shine lights over also won't change....
is it possible its disable or broken? please help, my phone is out of warranty, i was hoping for a DIY repairs on it, any guide or tips on which part should i replace,?
thanks in advance
Hey there. I'll just assume you're using a stock rom, and I'll asume it (your light sensor) is actually broken.
"Repairing" it wont be cheap, because it's part of the flex ribbon/cable assembly, which also holds the front camera, notification LED, proximity sensor, home button, display/touchscreen assembly connector and speaker pins. Pretty much everything is soldered to this component.
There *could* be a problem with your flex ribbon. Perhams some of its wires are starting to break? I know this can lead to all sorts of issues, because it started messing with my LED some months ago. But, on the other hand, it might just be a faulty sensor.
Whatever it might be, I say you leave it as it is. Replacing the flex is no joke on the XMP.

thanks for the reply.... im not on stock rom , its 4.04 zelly cream 6.0 AWESOME ROM!!! love it... but before i flash this, i already have issue with the sensor ...
hmm i saw a video on replacing the lcd screen, seems not that hard, just lots of steps... but problem is im not sure where to find the replacement part for the board as u mention, the lcd is common in ebay, etc...
thanks for the reply by the way. i willing to fix it myself as i love this phone alot!! i use it for work,papago gps map, calls, fb ,messaging thats all.. the keyboard and its compact body is my fav combination...
Ebay
Search on ebay for "flex cable sk17i".
Before disassembly please make sure that the cable you will receive has all the sensors and the camera. The first time I purchased such a cable, it came without proximity sensor... Unfortunately I cannot upload pictures or links, but google is your friend, right?
If I were you, I'd look for a flex ribbon with the "1241-7544" part number between the big gray square and the display port/slot. Genuine parts WILL have this number, cheap knock-offs don't (at least most of the time).

Sensor/s not working after screen replacement

Hello,
Leading up to this problem I had this awful screen issue (screen burn in) way before I did all that and ordered it to get it fixed.
When it finally came (in amazing condition) I replaced the old screen for the new one very carefully and booted it to power it on and it works just fine.
But issues popped up.
Double tap to wake would not work, and wave to wake up wouldn't either and now when I get a call the phone is stuck on a black screen.
Oddly auto screen brightness works just fine so I am thinking the new panel is causing the issue.
Solved!
There is a rubber gasket that eliminates light interference between the two sensors. When it is placed correctly the sensors would work just fine.
Sadly I did not know that the gasket was needed to be removed from the old frame to the new one. (it's not mentioned in most disassembly repair videos)
Sensor issue after screen replacement
I just replaced my screen on the same phone, and I'm having the same issue, before I open if up again, where's that located to be precisely? Just to know what I'm looking for. Thanks so much in advance
