Rooting triggered proximity sensor issue?

Hi all,
I recently received a replacement Desire for my 'faulty' one. I tested all basic functions before walking away and everything checked out.
After I rooted it and installed Modaco r17 ROM, My proximity sensor sensitivity dropped dramatically. When I make or receive a call, the screen blanks as it should, but when I move the phone away from my face, it stays blank. I can't end the call or use speakerphone or keypad. The only way to bring the screen back is to hold it under a very bright indoor light, or direct sunlight...or pull the battery, of course.
I loaded a sensor test tool (SensorList) and it confirms that the sensor is reacting only to very bright light. I've checked that my cover doesn't obscure the sensor and tested that the behavior is the same with or without the screen protector.
I tried a couple of other ROMs, Modaco r19 and Shadowfrost v13. I un-rooted my phone and dropped a stock HTC ROM back onto it...and the problem is still there!
I'm waiting on a reply from HTC service about it...but in the meantime...any advice? I've seen a few posts around the web with this problem, but no definitive solutions or answers.
Question Added to Developers
I've noticed a smattering of people in various forums, with various of the newer android phones having proximity sensor problems. Perhaps these are not quite as finely calibrated as the other sensors, or not as reliable. Have any of you developers seen a way calibrating or adjusting the sensitivity? Perhaps a value in a system file we can change?
Thanks in advance.

Apols if this is pushy. I added a question to you developers, so giving this a bump.

FYI:
Proximity and Light sensor does not work with Sensor List in a Froyo ROM. Tested it myself just now.

Images:
1. Holding hand over phone screen
2. Clear view of the screen in dimly lit room (it's quite cloudy )
3. While running FroYo
This does seem like Sensor List correctly detects and measures the proximity/light sensors in FroYo on an HTC Desire, or am I mistaken?

Ditto Issue
I have the exact same issue as yourself and believe that the problem itself started after I rooted my device.
I am yet to take it back to a Telstra store however as there is no un-rooting method I can think of. (The Telstra ROM will not install on my rooted handset due to incompatabilities that arose from rooting the device.)
Your best bet is to get it replaced again because I've flashed every WWE and custom ROM known to man in order to fix this issue and have had no luck.
Some of the responses you'll receive here are just ridiculous (no offense, as that comment was not directed at any of the above parties).
Hope it all works out for you mate,
Cheers.
John.

Thanks John. I tried the same thing with the same result.
I ended up taking it in to HTC. Luckily I came across a good service rep. He said they'd seen some quality problems with the first batches of Desires and mine was not the first faulty proximity sensor they'd seen. My guess is the timing with the rooting was coincidental.
They would have replaced it, but they didn't have any replacement stock at the time...more evidence of early quality issues. They gave me priority and repaired it in 24 hours. It's been running fine under a number of ROMs since.
BTW I had problems de-rooting and reloading the stock ROM. Then I realised I just had to have the original goldcard in the phone and presto! One day I'll learn to RTFM properly.
Cheers mate and good luck with yours.

I have also this problem. When I make a phone call screen goes black immediately and there's nothing you can do. After the call is over I can wake up screen by pressing power button. I'm not sure when it started because there's been so many variables. I even destroyed my invisibleshield thinking it caused the problem.
Sensor list and sensor dump says that max value for proximity sensor is 1. Screenshots above there was at least 9. Also light sensor doesn't work at all.
I tried to unroot and go back stock but the problem still exist.
Have anybody found a way to control these sensors or do I have to send my phone to HTC to get it repaired?
Thanks in advance!

Hi, I have the same problem here with my proximity sensor since I have used a custom ROM (I don't remember wich one because I have tried so many Froyo ROM before the OTA).
I can't send my desire to HTC because my phone is out of waranty since I have installed all these ROMs.
Does anybody's got an idea, some help from devs ?

OK,
Maybe I'have found a solution to the proximity sensor's problem... At least my proximity sensor is working normaly now.
What I have done (you can found all in the xda posts) :
1. Going back to Hboot 0.80 => forum.xda-developers.com/showthread.php?t=741672
2. Rooting the desire and install the new recovery using unrevoked
3. Installing the OTA 2.2 without the Radio 5.09 (not a leedroid or djdroid or any other ROM, just a 2.2 rooted)
4. Configuring my phone
5. Installing the 5.09 Radio
I don't think that I have doing anything else, but now I can call someone even in the dark and my screen doesn't stay blank anymore !
Hope this could help someone.

[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 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.

[Q] Samsung Galaxy Note 2 Motion Sensor and Gyroscope not working

hi i just recently bought a galaxy note 2 phablet, im very happy with it every thing works perfectly fine, however i did come across a slight problem which is bugging me alot, as i loaded the phone up it shows you all the tutorials and stuff, for panning and zooming in using motion control.... i did not realise the problem before as i was really happy to just get the phone after so long, My motion sensor and gyroscope functions are not working
i have tried everything from factory reset to restarting , taking the battery out and putting it back in, has anyone stumbled upon this problem, and is there a solution to this problem, whether this is a software glitch/problem or a hardware issue. if anyone can help me please and thanks in advance

hi thank you for the quick reply, i had a look at what you asked me to do and i did manage to find all the settings, however it looks to me everything is working apart from the light sensor one, all the other settings came up as a PASS apart from the light sensor which came as level 0, which i dont know what that means, while i was on the sensor screen i swiped my hand across the sensor and the screen shifted colour from white to yellow, which is a good indication that it is working , however i went back on the operating system and tried the palm swipe and it did not work, niether did the quick glance, and the pan to zoom features are not working either, i did test the gyrocope settings and it came out as a PASS too, could you explain maybe why this may be happening and what does the level 0 on the light sensor option means, please and thank you , i really do appreciate it.

Lavel 0 says to all phones I have tried including mine. As long as the LUX changes it is working.
Now for your primary problem try to recalibrate gyroscope.
Do it by going settings-motion-advanced settings-gyroscope calibration.
If that does not help try clearing cache in recovery.
If that does not help then backup and try reflashing your rom.

Hello in response to your issues with the motion sensor. Have you installed a screen protector on your note 2? i noticed that after installing the screen protector on my Note 2 some of the motion actions did not work properly. So if you do have one on remove it and see if that corrects the issue. :good:

Useful help.
This was a very Useful thread, thanks. I've done the tests and came up vitha a fail when i tried my motion sensor. Is it likely to be broken? I'm going to reset to factory settings and pull of my screenprotector and se what happens before i do anything else. Is there anyone out there who has replaced the motion sensor? Is it soldered to the main board? Hard to replace?
Thanks beforehand. Tommie.

i thnk my sensor is nt wrkin... when i do the test, d color is alredy green nd isnt changin nd is vibratin continuosly?? is it broken or somthng lyk dat??

Samsung Galaxy Note 2 Motion Sensor and Gyroscope not working
hi my samsung note 2 was working well for last 2 years bur recenrtly its motion sensor has stopped working.
i have checked all settings, it isnt working at all..
gyroscope and motionsensor tests are fail on checking. please help me, what to do?

I have had the exact same issue. The only way to fix it is to get the whole motherboard replaced. I went into Samsung store and they said that. Issue here is that it costs £145 to replace the main board. The sensors are on the main board itself and that is why it costs a lot to fix. I've been using my Note 2 with no gyroscope for a few months now, going to buy a new phone. Rather buy a brand new phone than get it fixed

just loosen the screw nearest to the microsd card. motion sensor is under it. it work on my phone.

gyroscope sensor
Hi,
my gyroscope is burned and i buy it and now i opened my phone and i don't know how to replace it. Any help is welcome...

Yeahhh!!!
You are a Hero! I tried nearly everythink since January 2016! I took the screw out, shut down my phone, put it into download mode and pull the battery out.
Im not shure if a restart would do it alone, i did all to be shure. And it now works again. My srew was magnetized! Maybe that was the reason or the chip has
a loosen contact.
Up to now it works great! I thought my sensor was dead.

[Q] Dead Sensors

Hi there everyone,
I've been a long time reader but first time poster hehe
I just got a slightly used Note 3 (build N900TUVUBMI7) and upon checking that everything was working properly I noticed some issues with the sensors, so I checked by dialing *#0*# and this is what I got on the Sensor tab: (you can see it in the attached picture) All the values are at ZERO!
I know chances are I just got broken hardware, but if that's not the case, are there are software solutions I could try to restore Sensor functionality?
Thanks.

Did you put your hand over the sensor to see if the value change?

I just checked one out, that had the same problem. In that case, the previous owner had replaced the screen and damaged the front camera with the sensors. Camera is very easy to replace and cheap. But he'd also broken off two contacts on the motherboard, which must have had a role in the sensor control. Got the camera working again, but not the sensors. If you can't return the phone, it might be worth buying a replacement front camera with sensors, but maybe open it up first, and see if anything is loose or disconnected.
