[Q] Proximity sensor problem(?)- can flashing a ROM solve it?

Hi,
I've searched high and wide for a solution (other than sending it back to Motofailure repair) and am failing at finding one so far. So I'm hoping I can get some help from here.
So, this is the situation: I make a call, screen instantly turns dark and will only light up again when I press on the area where the light (&) proximity sensor is.
I've already tried the following.
1.) Done a factory reset (3x) - with mem card, with reformatted mem card, w/o mem card.
2.) Clearing the dust on the earpiece hole using an air duster.
3.) There were times that I worked properly after I've uninstalled apps but the issue came about again after a couple of tries.
So, now I'm thinking that I might want to root my Defy to set things right. I'm quite familiar with RSD Lite as I've used it before on my RAZR2 V8.
A bit of background: I bought my Defy on pre-order so this is one of the earlier models. I had the earpiece problem and sent it to Motofailure repair and the whole process took a month (32 days to be exact - long story. I'm avoiding having to send this PoS back. They updated the software when I got it back.
As far as I can recall, I didn't had this problem before the earpiece problem. And I'm thinking it might be a software problem hence I'm now looking at a solution by rooting and flashing the ROM with an original one.
I have no way of finding out (as far as I know) whether this is a hardware problem (hence hesitating to have it sent back to Motofailure repair).
What I've also observed is that when there is direct bright light, it works normally but when its dim, then the problem appears.
I don't have any screen protectors, just so you know.
Can anyone advise me on what to do?

During a call proximity sensor is activated to turn off the screen at the moment it detects proximity and asumes you are using the phone against your hear, so it turns off screen to save energy.
I think you might have some app installed in your phone, using and reversing the sensor status so it detects proximity when there isnt, and viceversa
You might want to try removing apps using that sensor and see if problem gets solved, there is also an app in the masket called sanity; which makes extensive use of proximity sensor for vaqrious things, and have an option to reverse proximity sensor, you might want to try it and see if problem gets fixed.
You might try this things: remove apps using proximity sensor, test phone. Deactivate in pocket detection; test phone, and install sainity, test phone, install a new rom?

If speaker is bigger than original one, or there was an assembly error, light/proximity sensor won't fit into right place.
I've seen such reports and you can't do anything unless you open up thing and check the problem, but you haven't seen the right assembly so you may not know the right place.

Are you using any screen protector? I know some screen protectors cause this problem.
Edit: Nevermind, I see that you're not using any.

how to calibrate the proximity sensor?
My new defy 's proximity sensor seems cannot work correctly,when i making a call ,the screen shut off immediately，and the screen could not light on by any key,but when i touch the proximity sensor with my finger,the screen may be light on!
so i download a app to test the proximity sensor which name's"Android sensor data",this app fingue out the state of proximity sensor,"near" or "far",sometimes I just passing my finger over the proximity sensor, the reading will show 'near' and then remain 'near' even when my finger is moved away!
Can anyone else help me to calibrate the proximity sensor?google told me some android phone can do this ,such as htc, zte etc.
goole tell me android phone have some standard testcode,such as *#*#4636#*#* can show the phone statue,it works correstly in Defy,*#*#0588#*#* test the proximity sensor ,but it doesn't work in defy!!!

I don't think this issue could be solved trough software tweaks. Chances are this is a hardware problem. Maybe you should contact the Motorola support.

try disabling in-pocket detection

have the same problem. it started 2 days ago. Im using CM7. It just turns dark and wont wake up unless someone else is calling me. Just got it tested, and when i cover the sensor with my finger it says 0cm distance for long time.
I've tried data wipe and similar, but nothing helped so far.
EDIT: I've just tried wiping the place where proximity sensor is with some soft cloth and alcohol and for the time being, it works. O.O

Could Wipe Dalvik help?

[Q] proximity sensor problems

Soo.. it started a while ago, i switch roms alot and i am very cautious when it comes to kernels and i try to flash the right one every time but with the S-ON limitations it has been some kind of confusing
to be exact, i flashed the pokemon rom with the kernel impeded through fastboot
and the proximity sensor is not working (not turning the screen off during calls)
and i flashed bricked, faux and franco's kernels and still its not working
and no its not physically damage because i had IC rom before it and it was working fine
does any one know what is going on, what i might be missing or something i could try
anything will be helpfull
Cheers

i installed an app called AndroSensor and it said for the proximity sensor check "faliur to start" and then after a while "waiting for event"
if that might help
and the light sensor is "waiting for event" too

well i solved it.. i dont know what actually happend but here is what i did
first i tried to flash the new franco kernel along with its modules and it didnt work (didnt boot)
so i thought to try not just the stock boot image (as it is provided in the pokemon flasher) but also the stock modules (as i dont own a widnows i cant just run the script file)
i unzipped the franco modules, replaced it with the stock modules and repacked it, flashed the stock boot.img in fastboot, flashed the repacked modules from the recovery and i got the proximity and the light sensor working again

could you please help me, my proximity sensor is not working at all...and i dont know why, i changed the kernel and the modules and it havent come back..., the light sensor is working well

I have the same Problem. Light Sensor is working. Proximity Sensor suddenly stopped working. There is no reaction when i use z-device test. The weird thing is, it passes the HTC function test and the red light turns on when i try to get a reaction of it in z-device test. It seems to work somehow but is not reacting to movement. I hope there is a fix for that. I don't want to send it in for the 6th time.

So it seems that my proximity sensor is not broken. It just needs very high brightness values to work. So in a dark room it won't work. Is there a way to calibrate the proximity sensor?

Even I have the problem of non-operation of the proximity sensor and light sensor lenses. After various tests and seen several videos, I realized that the problem is in contact with the sensor to the motherboard. Pressing close to sensors, close to the camera (back) everything returns to normal ...
Sorry for my English ...

I know this is an old thread, but I'm having the same problem as guistanca. Thought it was broken, but squeezing the phone made it burst back to life... dodgy?

Same problem like giustanca and peedub, any ideas,? It is hardware issue or it can be fixed by some software modification?

Ik have the same problem sinds a month, pressing the screen on the upside wil help to get the sensor to work again.
For me it's a hardware faillure i think.

Exactly my situation but when I press screen on the upside it help but just for I whine, few second and sensor didnt work again. I will wait for new official Jelly update 4.2. and if problem will be still remain, probably I will send my One X to service.

[Q]Proximity sensor - software or hardware problem? (video)

Hi guys,
I've got really strange problem with my proximity sensor.
It seems that my proximity sensor has stopped working or to be more specific it does not work in places where is not enough light such as in rooms etc..
Currently using CM7.2 stable but when I unroot my device and flash original ROM the problem is still there.
It causes problems when I make calls, the screen goes black+lock and after I finish my call the screen does not get back so I can not end my phone call.
What do you think? It it software problem which can be fixed somehow or reason for claim warranty?

[Q] Proximity Sensor and compass, both not working any more

As title says: since i rooted my desire hd and flashed a custom rom, the proximity sensor ( G-sensor) and compass aren't working anymore. Tried to calibrate, reset, hard reset, flashed other roms, nothing helped. While calibrating, nothing moved, not the levelers and not the needle of the compass.
What relation do they have together? Is it one part? Could it be a hardware problem or just software?
I noticed some threads about a locked G-sensor. Tried to "shake" them loose. No result. Who can and is willing to help me? thnx.

Mine proximity s. isn't working either. I guess I will take it apart and have a look at it, could be dust or smth.

I replaced my Earspeaker yesterday since the sound had been really bad for som time.. while doing this I removed loads of dust located behind the Grid at the top the phone.. doing this ofc fixed the sound, but i also made my Proximity sensor work again.. and made the GPS get a better signal.. so really try cleaning it.. does wonders...

Try a fresh install of an RUU (going back to stock).
If it doesn't work then it shouldn't be a software issue.
Normally rooting does not affect those things.

When I flashed cm7 to my DHD the proximity sensor stopped working. It was an issue with the sensitivity settings of the sensor not being correct for AOSP roms. I fixed it using the app in this thread.

It's strange but try, in first time, to clean the sensor with a cotton-bud. If it still deosn't work, try to recalibrate your proximity sensor with the following apk : DHD Proximity Sensor Recalibrator
Good luck !

I had the same problem.
But today I was replacing the back cover with the black one and in the process I saw A LOT of dust around the phone's earspeaker. The proximity sensor was hardly visible at all. I cleaned it up, put everything back together and it's working like a charm. Even power led is now 2 times brighter lol

I get a huge error when I use DHD proximity recalibrator.. and I also tried cleaning with a cotton bud.. the problem still persists..
