[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.

Proximity sensor seems to not work anymore

I first noticed it when the screen didn't black out during a call. Then I downloaded an app which checks if there is a proximity sensor and the distance it reports. According to the app, the last distance reported is 5 centimeters and it doesn't change at all when I obstruct the sensor. That makes me pretty sure that it stopped working. What can I do now?

If its anything like mine, you'll start getting some even weirder behavior. When I would answer a phone call (or place one), the proximity sensor wouldn't work and the phone would reboot itself within 5-10 seconds.
I downloaded an app called "Hardware Disabler" which allows you to disable the proximity sensor on the Gnex (its the one labeled 4-0044). It works for me...only annoyance is having to turn my screen off/on during phone calls manually. But, its better than having no phone (i.e. soft reboots).
Anyway, to answer your question, i'm not sure there's much you can do (other than disable). I've read that the proximity sensors on these GNex's are a little buggy.

My Nexus Reboot During Call once in day too !
maybe my reboot problem is Proximity sensor ?
change my simcard and factory reset not solve my problem .

I have had this issue. Do you use a ROM with the active display feature? A lot of ROMs have been including this lately. I feel like my issue started when they added that. It has a "Pocket Mode" option that uses the proximity sensor and I've always felt like it messed up my proximity sensor during calls. I never had reboots but the screen would flicker on and off during a call. Sometimes just staying on. I have turned Active display off all together and sometimes it will work right and sometimes it will flicker. But for me, it seems to have started when ROMs started including that feature.

I'm just gonna go ahead an suggest the obvious, flash another ROM. Even stock if you aren't running it just to get collective results, this way you can eliminate the ROM factor.

It sometimes does it for me too, but it's very very rare. Sometimes the phone just freezes during a call (when swipe to take the call).

Can't speak for others, but I tried everything that could be tried. Flashed different Roms, kernels, and even went back to stock using the images provided by Google. Nothing fixed it until I realized it was a hardware issue. I haven't had a single problem since disabling that sensor.
EDIT: also, to clarify, it wasn't an intermittent problem for me. I could NEVER make/receive calls until I disabled that sensor.

Flash Catalism rom and disable Proximity sensor solve my reboot incall problem !

Proximity sensor is buggy, can't find a solution.

Hello,
I bought a Redmi 1s online and from the very first day, the proximity sensor doesn't work well, whenever I made a call, after putting the phone near my face, the screen goes dark as normal but it sometimes just won't turn back on. I tried calibrating it through *#*#64663#*#*, I was able to calibrate fine 2 times, but after putting a screen guard on, the sensor became buggy again.
*I've tried flashing different ROM's which doesn't help
*I've removed the screen guard and still buggy
*I cannot calibrate the sensor anymore and just fails
*I've tested the sensor with a 3rd party app from play store and it seems to work fine in that app.
I'm currently out of ideas, can anyone help me?
PS: Sometimes, the screen goes off right after hitting the call button and wont turn back on until the call ends.

Yes problem with proximity sensor was their and because it was on base rom so it reflected in other roms too. Currently i am not experiencing it in miui 6. So either try miui v50 (Latest official stable update) or try miui 6.
Again its a software problem and will be solved.

No notification LED after MM update on ZE551ML?

Maybe it is just me and my device, but since the MM update (the real one, not the beta) my notification LED doesn't work. I have tested it with text messages, emails, missed calls, charger plugged into my computer, charging plugged into a standard charger, and charging plugged into the fast charger... nada on any of them.
Anyone having this issue? If so how have you rectified it? It has been a minute since I first got this thing (got it at launch) and the MM update reset all my settings so maybe there is a setting to turn it back on I am missing?
Help out a brother if you can. Thanks.

OK, so does anyone have any suggestions for an app that might help by letting me manually setup the notification LED?

Thanks for the reply. It is not in DND as far as I can tell (not on).

If you haven't already, try a factory reset first

Have you found a fix for that? Facing the same issue and so far no luck.

Actually yes. After I wiped my phone for my wife the notification now works.
Another issue that I recently found the solution to... if your ZF2's proximity sensor has gotten crazy sensitive since the update try cleaning it. Seriously. Especially if you have a tempered glass screen protector. I thought the piece of advice was bogus but I cracked out my lens cleaning spray and cloth and BOOM, the proximity sensor works correctly again.

Thanks! Got the led working again after a factory reset.
By the proximity sensor do you mean the little one next to the selfie camera or the GPS?
After a lot of fixed I've got the ZF2 working fine, except for the "smartlock - safe places" that thing can never work right.

Sorry, I just realized that you had replied.
Yes, the one beside the camera. Many have had an issue where the screen goes black after you start or answer a call, especially after the update. It seems the update made the proximity sensor much more sensitive. Since all decent screen protectors have a small cutout for the proximity sensor it will tend to accumulate dirt and oil from your skin. Wiping it down doesn't seem to get it clean enough for the sensor so you have to get a little more aggressive to clear the problem up. I went months enduring the problem and even set my phone so I could disconnect from calls using the power button and then ended up stumbling over the solution when setting up the phone for my wife when I upgraded to my Axon 7.

No led indicator
Hi i've been experiencing the same issue. After I update my zenfone 2 ZE551ML 4gb/64gb version, I have noticed that the led incator is not working and it is not found in the settings. Also, another issue I have encountered is that quick charging feature is not working sometimes but sometimes it works. I don't know how to fix. I'd be glad if someone could help with a step by step process. Thanks in advance!
