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 kine of stopped working..
If I make a call and place the phone to my ear, the screen will turn turn off, but when the phone is pulled away it won't torn the screen back on.
This makes me believe is not a hardware issue just a little software conflict with maybe some app that maybe be solved by resetting the phone off but I don't want to do that.
Does anyone know which app I can clear off data/cache that may make this thing work again?
Note: I have used AndroidSensor and some other apps to test proximity ans light sensor and they don't seem to work, according to the app.
Thanks.
Edit: Never mind guys, I deleted the last 10 apps, rebooted and it came back to life.
Delete thread ......
So this is strange. Using stock Samsung ROM and dial *#0*# the proximity sensor works off the light sensor values. Proximity will be 1 until held right in bright light which at that point will be 0. WTF! I've been having a problem where the phone app uses the proximity sensor to turn off the screen and I can't turn the screen on unless the other end hangs up(big problem when it goes to voice mail) or i run to a bright light so the screen comes back on.
light sensor goes below 60 lux phone will start vibrate.
light sensor goes above 110 lux phone will stop vibrating.
I've tried many ROMs and kernels with no success and have Odined back to a stock Samsung firmware to start over. As of right now nothing should be different from when I got the device. Anyone know whats going on? I'm about to call Samsung for a replacement but wanted to see what people here say first. also I've been flashing ROMs for many years and have never seen this.
My understanding is that proximity sensor in note 2 is set for 8 cm and values are either 0 or 1 above or below 8cm

I have this exact problem here was my thread a few months ago:
http://forum.xda-developers.com/showthread.php?t=2099898
and the only response was to factory reset (which I haven't done yet and from what you're saying that won't fix the problem either...)
Quick question, I only see 1 light coming out of the two holes at the top of the phone, are there supposed to be 2 lights? (you can check using another camera since it uses infrared)
-- edit --
just found this thread on sprint forums:
http://community.sprint.com/baw/message/544084
apparently the person had a tech open it up and air out the sensor
Easy FIX!!!!!
I took a can of compressed air and blew it through the top earpiece grill a few times and Voila, it works great now!!
I actually used a Old perfume can wich purfume was over and it was only pressing Gas OFF!!
same issue

I had the exact same problem with the proximity sensor and other weird sensor issues. I had never rooted or anything. T-mobile exchanged my phone for a new one.

This fixed for me too. But the sensors start acting up like every couple weeks and I'd have to blow air into the ear piece.
i9100 proximity sensor doesn't work
Hi to all!
I have the issue with proximity sensor and didn't manage to find a solution in other similar threads!
The matter is that it is always stay as Released.
In the same time in test screen (*#0*#) there are changing reading for PROXIMITY parameter from 2 up to 240 with no ADC parameter at all. Please look for screenshots. PROXIMITY parameter changes its value when I move my finger in front of the sensor, but as I can understand Android doesn't recognize it because of ADC absence.
Moreover I tried to change proximity sensor for working one (from another phone), but it shows the same as mine (with no ADC readings).
After all I think it is software problem, but I don't know how to solve it. I flashed different firmwares (now it is XWMSE NeatROM v.6.4), but nothing helped.
Please assist! Thanks!
TRY THIS
Sensor fix installed through a custom recovery I use when flashing aosp ROMs might work but I only use it on my Liquid Smooth updates might work for you. Just have a backup in case

It didn't help! After the fix is installed the sensor works at the same manner... Is it possible to try something else?
hello..
I am using a htc desire hd.. rooted and running on android revolution hd 7.3..
my proximity sensor all of a sudden just stopped responding..
is there any way that it may be the software which has gone or is it a hardware problem!!!!
PLEASE HELP!!!!

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..
The proximity sensor usually does not work.
Any news?
It is harware or software isuue?
Thanks

all by sudden, my F3 has it proximity sensor working on call today. It's not a joke. Does anybody experience the same? Something change?
My prox.sensor sucks more than anything else that ever sucked before.* Got very angry, and i am skeptic about solving sensor issue in upcoming updates (if there will come some)
* ©Butthead, not Beavis
After I updated to the latest stock rom, it worked and it is working all the time.

There are NO proximity sensor hardware in the phone, it is only emulating proximity feature using light sensor and etc.
If you test proximity sensor with hardware tester app, it only works when phone is vertical lol and even then it's janky.
The good news is that this can be improved through software.
I guess you are all talking about stock ROM, right?
