[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?

Proximity sensor issue...please help

the phone screen should turn off when in a phone and close to my ear due to the proximity sensor
but the screen doesnt turn off....i dont know why
its a stock desire hd with the recent gingerbread update so its not rooted.
any ideas for troubleshooting?
its really annoying
i have an app that tested the sensor and found no issues (ie, it measured me moving my finger on and off the sensor without issue)

no root, cant help much, no custom kernels

iv always had the same issue, even with Lee's rom installed, the proximity sensor never seems to pick up at the right time.. is there any way of calibrating it?

There was an app on xda somewhere for calibrating the dhd sensor. Try a search on here and try Google. Think it might be a known bug with some dhd.

thanks, yeah i read that thread, but i'm using GB stock, and unfortunately its not yet supported by that app.

Hello. My Desire have problem.
Proximity sensor don't work correctly.
When I call somebody, my screen off (black) at once.
I download program "Proximity Sensor Finder" and I found out that phone always think that distance between "sensor - anything" always 0.0 cm
What to do?
Maybe dust on sensor...but i don't understand how it could get there

hm maybe a software bug?
what radio an rom do you have? did you try another rom and radio?

radio last 5.17
i tried a lot of roms but problem still exist

Go back to stock. If problem still persits, call HTC.

i had same problem like you before
and it solved right now just by clean the dust around the ear peace with rocket air for camera lens
try it adn i hope working with u too

[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.

Did u try Rezound Proximity Sensor Ca|ibrator from P|ay Store?
Play with the settings-PS1-CANC whi|e moving hand over proximity sensor .

Turn off sense rotation in the homescreen tab of the tweaks app if it's enabled ?
