Trying to find Xperia Z3 proximity /dev?? - Xperia Z3 General

I am having issues with my Z3 proximity sensor being activated when it's not supposed to.. e.g. when I receive a call the screen will just go black and I cannot answer the call or even see who is calling me, same when I dial out, I just have to hope the other person hangs up or I have to soft reset my phone with power + vol up until it turns off then restart.
I have tried all the silly apps and none of them work, or they are just bloated with ads etc. and besides I would rather not have to rely on an app for this. I have read in a few places that the proximity sensor is at /dev/cm3602 but only on certain devices, and possibly only on ICS/JB.
Surely there must be a way to disable the proximity sensor via root shell?
I have tried so many things, at first I thought it was a firmware issue, but after trying various ROMs I figured it's not. What confuses me is that the proximity sensor and light sensor are the same sensor, and the light part works fine but the proximity doesn't.
Is there anyone out there who knows anything about this? Has done this before? Or is willing to give me any idea on how to get going in the right direction?
Cheers in advance..

Disable proximity sensor while on a bluetooth call

I am unable to pull down the notification bar while on a call using my Bluetooth headset. When my finger gets near the top of the screen, it trips the proximity sensor and blanks the screen. I'm not sure if this is a design flaw or something that I can fix. There are MANY times that I want to use my phone while I am talking to someone and it seems stupid to me that I cannot interact with notifications while I'm on the phone. Anyone else experience this issue and/or have any suggestions? Thanks!
Swipe down starting at the htc logo or just to the right of the center. The proximity and light sensors are just left of center.
This works, just tried it.

No fix yet I'm afraid I'm sure the developers here will figure something out though...
Thanks so much for the information guys. Glad to see this has already been brought to Sprint's attention. Hopefully they will get a fix pushed out soon.

Screen locks immediately during calls - proximity sensor not working?

I have two SGS4's. On one, when I place a call, the call screen stays on and it turns off when I raise it to my ear. It then turns on when I pull it away.
On the other, as soon as I place I call the screen goes dark. The only way to get it back is to push the power button and unlock the phone.
The "Turn screen off during a call" setting is set on both phones.
Anyone have any idea what is causing this? Next step is to do a wipe, but that just sucks.
I'm on stock and not rooted.
Thanks!
Sadly I have the same issue on mine but not my wifes.... hope somebody knows something or maybe the rumored update thats going to be coming out will have a fix?? I dunno...

Have you tried doing a reset yet? I'm hesitant since it's a pain to restore everything the way I like it. Definitely a weekend task.

Nope, mine is naked for now. I'll have to do a reset today/tomorrow and see if that solves my issue. If not, I'm taking back to the store for an exchange. It's only been a couple of weeks.
To late for me to take it back but suppose to be a update coming soon that does alot of fixes so we will see Good luck like I said reset I did notice fixed it a bit let me know how it goes I'm threw sprint just curious if you have them only reason I ask if it's just a carrier issue with software or something I doubt it but just figured to see who you had lol

That's what I was looking for!
Sure enough,the proximity sensor was always on and wouldn't go off.
I'm with T-Mobile and they have a 30 return/exchange policy if you buy it outright, which I had, so it only took about 10 minutes for them to exchange it!
Thanks for the testing code! XDA comes through once again!
Same problem when I'm making a call, the screen goes blank when I put it to my head and when I remove it nothing happens.
I tried *#7353# and the proximity sensor goes of but will not stop..
I'm currently rooted, could it solve the problem to go back to stock?

I have had the same problem over the last 3 weeks and decided to take a gamble. I tightened up all the screws on the device and squeezed real hard on the area where the prox sensor is and poof... it works. I have no idea what was up but I feel like the sensor is loose and the pressure resolved the issue. Many other post have talked about cleaning the area over the prox real good and it works but I think its the pressure that is actually fixing the issue. Anyone else have any ideas? Sorry if this was posted incorrectly, I have never posted before but I felt this issue is a PITA.
I have i9500. Unrooted with latest OTA update installed (Build XXUBMG1).
I've been having the same problem with proximity sensor. When proximity sensor is enabled during phone calls (both regular calls and Viber calls), the screen is disabled. Also, my screen sometimes remains on during the call until I place it to my ear and sometimes it turns off immediately during the call. It wasn't always like this, but I can't remember when it started happening, but I suspect it was since the last OTA update.
I've searched around online and have noticed several comments.
Apparently this is an issue with several Galaxy models over the years (sorry, I lost the reference) and this thread: http://forum.xda-developers.com/showthread.php?t=2208440&page=2 mentions Galaxy Note 2 and SGS3 having the issue where there is something wrong with the threshold setting in the calibration settings. Mine appears to have the same issue where it always reads 0cm (i.e. always covered). However this thread also suggests a fix to input some code to adjust the calibration if your phone is rooted.
One suggestion is there is a misalignment of the sensor and so it might be partially covered by the phone's front fascia, causing the sensor to always read as covered or "1" or 0cm. But looking carefully at mine, it looks centred dead-on.
This thread http://forum.xda-developers.com/showthread.php?t=2417401 indicates that the sensor is always on as can be seen through a digital camera LCD (but not with your naked eye). I've tried this with my DSLR and confirmed this also happens with mine, even when the option is set to turn it off during calls, and also even when air gesture (which uses the prox sensor) is turned off. Not sure if this affects the problem or not though.
Can't remember where I read this, but someone mentioned that when shining a bright light over the phone, it works. So I downloaded two sensor apps from Google Play: Android Sensor Box, and Proximity Sensor Finder. And also used the inbuilt *#7353* feature. All three report that my proximity sensor is always reading that something is constantly covering it..... EXCEPT when a bright light (the sun works) is shining on the light sensor - not the proximity sensor. I tested this by using a torch on both sensors. When blocking light from the light sensor, the problem persists, but not when I allow the light to shine on the sensor. So it appears that they both act in unison.
Similar issue with air gestures, which used to work when my phone was new, even in relatively ambient light (but obviously not in a dark room), but now doesn't under similar conditions, and again... EXCEPT when a bright light is shining on the light sensor, or when I'm out in the sun.
Anyway, I'm not willing to root my phone at this point, just to try the fix suggested in http://forum.xda-developers.com/showthread.php?t=2208440&page=2 (my phone was bought overseas and returning it wouldn't be convenient for me). And since this wasn't always a problem with my phone, I suspect it is a software problem related to one of the recent OTA updates.
Edit: After further testing, it seems that air gestures use the front camera as well as the light and proximity sensors.
My proximity sensor works - when I go into diagnostic, it goes green when I bring a hand near the sensor - my issue is that it doesn't seem to notice when I remove my hand and there no longer is anything proximal - until I hit the back button to exit the test. Other than blowing out the earphone jack, does anyone have a suggestion?
Thx.

Proximity sensor
I had problem with proximity sensor in my galaxy s3 mini but my rear camera had error and fc also.I tried everything and nothing work.Finaly I open device and disconect camera and connect it again and camera started to work.But for my suprise proximity sensor now works perfect and I did not touch it.I can't explain what happend but I am happy.
I guess what it comes down to is.....for some you can reset the sensor, for some they can blow it out with compressed air, but others actually have to take apart their phone to fix this issue.

hi
i have the same problem. any solution guys ?
( BTW - im on NB3 INS firmware )
I think I summarized the available solutions just before your post. There is no single thing which always works, you'll need to go through and see which fixes yours. This happens primarily because of hardware, with the sensor getting dirty - so it comes down to how invasive the procedure to clean it.

Priximity sensor.

Hi guys is there a tweak someone created or exists that can disable the proximity sensor on the s4? Is it possible? My proximity sensor has issues where in a call the screen goes black and doesnt come back on even if i press the home button or the power button and its really frustrating. Ive seen some posts about going into mobile terminal and changing things but i could never figure that out i would like it if someone could explain how i can disable my proximity sensor thank you

[Q] What mod allows you to disable the in-call proximity sensor?

Hi everyone,
Long story short, I got a used Nexus 4 off someone, everything works perfectly except the proximity sensor. During a call the screen blacks out and doesn't come back unless I hard reset the phone to hang up. I figured out it was a problem with the proximity sensor. Upon reading these forums and many other articles on Google about taking off the screen protector (which I don't have) and swapping the rubber "sensor" holder holes, I decided to open the phone up and take a look.
It appears that my phone is missing the rubber piece to hold the proximity and light sensors in place, making the sensor unusable and causing many issues with making calls. I've tried playing around with it using other peoples' suggestions and nothing has worked. I've decided to just find a way to disable the proximity sensor instead during a call, as I'll be quite satisfied with just a simple software fix.
Right now I am using Proximity Screen OFF to keep the screen on, but it drains my battery pretty hard. I was thinking to just flash my phone with a mod that allows me to turn the proximity sensor off during a call.
Any suggestions as to which mod contains this feature?
Thank you.

[Q] Mi2s Proximity Sensor Not Working

Hi,
I'm running CM11-20141112-SNAPSHOT on my Mi2S, and I have a problem with the promity sensor. When I check its status in the Phone tester app, it always shows "near" as the sensor status, and the behavior when making a call confirms that - the screen goes compeltely dark until I press the side button to unlock the device. I'm not using a screen protector.
However, since I spent quite a lot of tiem installing apps and customizing the the ROM before I found that out (my bad, I know), I'd first like to know if there is something worth trying out (different kernel?) before I wipe it completely and try a another ROM.
Also, since I'm no ace at Android devices, perhaps just the fact that the sensor app shows no activity is proof enough (even though I hope not) that the sensor is dead, in which case I would not need to tamper with anything and just issue an RMA. Any help would be much appreciated.
Thanks
Hi,
Well, if the sensor is really damaged, the only solution i would advise you to "temporarily" fix this issue, is to install Xposed Framework and the famous module called Disable Proximity.
This, at least, will prevent you from having to press power button to make screen turn on, as it will be always on. (and no, there are no real risks of doing something wrong in your MI2S with your ear)
Thanks. The proximity sensor is as good as dead that way, but considering that I can now actually make calls, I' say it's a good tradeoff
