I remember one thing that happened after putting a custom rom on my Desire HD was the proximity sensor started working pretty badly. Luckily there was a calibration tool that I could use to tweak it back to normal.
Has anyone had any problems such as this or anything else in general I should keep in mind before rooting the Galaxy Nexus?

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.

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.
Recently I rooted my HTC desire and installed the froyo stock rooted rom, the person who published it says that he did not change anything in the Rom however I'm having problems with my magnetic field sensor. The compass app just goes crazy, doesn't point in the right direction plus Google sky maps also does not work. Please correct me if I'm wrong but my theory is that is the magnetic field sensor at fault. Does anyone know how to fix this?

you can calibrate by going to compass and waving it in figure 8 direction 3-10 times. this might help the sensor.
compass / gps only works once. root problem?
I am having the exact same problem with my rooted samaung r720 vitality. I am not sure if this problem existed prior to rooting but as I can't get a stock rom or back this one up I can't test it. I can't see why a root would cause this problem but who knows. I also have a problem withe gps it only works once maybe you can try this too. Download gps test put it in airplane mode go outside let it run for 2 mins after getting a fix shut off gps fix/ gps for 2 mins and then start it up again repeat this one more time (3rd time) then report your results.
With regards to the compass if you calibrate it it will work for a shortime but this is soon lost. I only have the problem with horizontal movement not vertical. It seem the calibration/ ofset settings are not being remembered.

fixed. used another persons nandroid backup of a stock rom. probably firmware was faulty not from rooting process.
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?
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.

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?
