[Q] proximity sensor issue after phone got wet - Sony Xperia Z Ultra

phone got wet and started bootlooping when I plugged it into a charger. I dried the phone out by putting it in uncooked rice and it now works fine except that when i make or receive a call the screen goes dark. Proximity sensor finder reports last distance as zero and the reading doesn't change when I put finger over proximity sensor or take it off. Is this a hardware problem?

Have you tried to pull it away and look at it? Cause even during a call my screen stays dark but when I pull away it comes back on.

[Q] Proximity Sensor settings too high?

Hi everyone,
funny thing happened to my Mozart. Whenever I make a call the screen shuts off like it should, but it doesn't turn on again when i remove it from my ear until the call has ended.
Which works fine if the other person hangs up, but it means I can't hang up. Whenever I reach a voicemail i have to take out the battery to hang up!
First i thought it was a rom issue, i had just gotten my hands on the mango beta when i first noticed it. I thought it might be buggy.
But the problem remains after hard reset and flashing with a different rom (pre-nodo & nodo).
I found out that the sensor still works. The screen is reactivated when i shine a bright light (halogen spot or so) onto it - but only for as long as the source shines onto the sensor, else the screen shuts off again. wierdly enough, direct sunlight doesnt seem to be enough to trigger it anymore.
since i upgraded my phone with a 32GB microSD I guess I'm not eligible for warranty, huh? but im pretty sure it happen long after and i didn't accidently break something while opening the phone.
very weird... any ideas?
I had this problem on the weekend.
I removed the matt screenGUARD, and the problem disapeared.
Also you can reactivate the screen by pressing the on/off button...
thanks for your comments.
unfortunately, I don't use a screen protector and the standby-button doesn't work during a call
I have this problem also, with stock 7392 rom. The sensor seems to work when dialing, but stops a short time after a call is connected.
The power button works for me to turn the screen back on however...
Where is the proximity sensor ?
where on the device is the proximity sensor located?
I have been having difficulty with the screen not switching on during phonecalls and I have to remove battery to end outgoing calls. Pressing the power button doesn't help either. I don't have a screenguard to remove.
The problem started not long after, but not immediately after my daughter dropped the phone down the toilet. It took a few days for the phone to gently dry out and it worked again except for some residual water between the screen and the glass.

The sensor is about 1 cm to the top and right of the htc logo. It's barely visible and it is dark violet. (Or something like that, I am not very good at naming colours.)
Anyway, I sometimes also experience problems with sensitivity with HTC Mozart, mostly during calls, especially when the proximity sensor has been activated. Sometimes the home button freezes after a call... It's a bit annoying.

Help broken proximity sensor

When making a phone call, the screen goes blank when putting next to my head, then remains blank when the phone is removed from the head area. Must hit the Home button to get the screen back. I have no case on my phone but a screen protector and screen protector isn't covering the sensor. I check the proximity sensor in call setting and it's turn on. Not sure what can be causing it not going back on. Any help would be appreciated.

I am having the same problem. I dont think that it is broken thought because I can make a call by bringing the phone to my head from a contacts page.
Did anyone figure this out yet? For those that are seeing the problem are you running stock rom, did you root or make any mods?
I see this issue as well, but was thinking it may be due to the spigen glass cover I have on, but I just checked my sensor reading and it appears to be reading things fine, it just wont turn the screen back on after. I am rooted on Stock, running nova prime as my launcher, not many other mods I can think of.

I cannot get my proximity sensor to work either! It is really ticking me off. I guess I will have to try get Verizon to give me a new one.
yea, I ended exchanging my phone since it was a broken proximity sensor. WIth my broken phone, if i squeeze the sensor for about 10 seconds putting pressure down and released, the proximity sensor will work for a few minutes. If you are able to exchange the phone, I would recommend to do so.

I would recommend you to test it.
Click on "Phone", you should have numbers on your screen now. Type in *#0*#, click "Sensor", now hover your hand over proximity sensor, if the screen goes green and/or phone starts to vibrate, your proximity sensor works. If it doesnt, i think your proximity sensor is broken.

Phone display turns black with phone call ??

I noted each time I make a call, the display immediately turned black. It auto turn black without me even taking up the hone up to my ears. I needed to press the power switch to have the display lit up again. Is this a proximity sensor defect ??
Same issue

Yea I'm dealing with the same issue on my at&t model, it's definitely a proximity sensor issue. Also, I find that the proximity sensor functions relatively OK outside of the phone app when I'm on a call in terms of lighting of fading to black...I haven't found a fix yet, hopefully it's a software issue though somethings telling my it's not... Just another defect in a long line of LG phones as of late

I have a same issue but clean the proximity sensor and it will work. The proximity sensor is next to the speaker. Clean with your t-shirt or jeans.

I've cleaned it several times to no avail
I have noticed occasional "quirkiness" while in the phone app, but not to the point of requiring a battery pull. Example, connected via Bluetooth, while plugged to a charger in a call, no way to wake the phone without pulling the charger.

Thank you. Thank you. Your proposed solution works very well. Now no more this problem. Had never thought the sensor could be dirty or blocked over time. I had the phone only about 2 months
Problem update
Okay, I've found new info on the proximity sensor problem. Firstly, I noticed that my proximity sensor still works with the second screen, if I cover it up when my screen is off it goes black and comes back on when I remove my finger. Secondly, if I was on the phone but not actually in the phone app it would behave normally sometimes. Now today I found out that when I'm in the phone app, if I'm talking on the phone through the speaker the screen does not go black, as soon as I take it off speaker, the screen goes immediately blank. Still have not found a fix, but just more info that may help define what the actual problem is.
anyone have any update on this? this issue seems to be getting worse for me
Same issue, drives me nuts. This phone is a disappointment to me overall. Have an S7 on pre-order with Verizon. Can't wait to get my hands on it!
Had same issue just happen on the AT&T LG Escape 2. (Yes I know its a year since this thread was started)
It was the proximity sensor but the "T-shirt wipe" method didn't work for me.
What I did realize there was some gunk on the sensor, and I used a cotton swab (Q-tip) with alcohol and rubbed it till it was visibly clear of gunk. Now it works fine again..

Turn of Gestures
Was facing the same issue
Went into settings
Call
Turn of both gestures auto answer and flip to silence

My screen started being always off during calls regardless of rom

Another thread about this stupid sensor.
My screen goes black when I call or answer a call. If I use a headset sometimes randomly the screen comes on or stays on when I answer a call.
The proximity sensor is working. Looking in *#*#7378423#*#* > Service tests > Ambient Light Sensor.
Putting it to a lamp gives a value of 10.0 and putting my finger over the sensor gives 0.0 .
So its working.
This seems to not be rom related if not for the change after Android 4.4. I flashed roms from cm-12.1-20161016-NIGHTLY-togari.zip, AOSP_N_161207_togari.zip and now I am on hybrid_concept_edition_2.0.zip.
I do have a screen protector on. But with a hole for the sensor. Its not dirty in that area. And the sensor worked fine way before I installed it.
This started happening during the last two months or so.
I tried numerus of apps from play store. None did anything. Of course I could force the screen to be on. But with the risk of pushing some buttons when I'm in a call.
My temporary fix so far has been to enable end call with power button
Do you have any idea what to do?
Thank you
I'm facing this same problem, I'm on stock.

yup.. I had mine apart today. But you need to remove the battery in order to flip the motherboard around to get to the connector.
I don't have time for that. Perhaps the battery will explode if I try to remove it..
So I cut a piece of foam plastic to fit around the usb connector so there is a constant pressure applied to the motherboard when screwed down the NFC antenna because there is a screw just around this area that sets the NFC antenna in place.
Hang on. I just made a call just for the sake of it that you answered to my thread and it freakin works!!!!!!!!!!!
I got the idea from this guy/gal: https://forum.xda-developers.com/xp...olution-proximity-sensor-fix-z-ultra-t3595525

Proximity sensor broke amd always on display..

I am new to the site so hello to all.
I have a sprint LG V30 with android 8.0. I recently had the screen replaced as my fone fell out of my pocket, in the rain, then got ran over by a car. Yes it DID survive but had to replace the screen. Anyway, the proximity sensor no longer works so I turned it off. So the light sensor seems to control my always on display. When it's slightly dark, the A.O.D. turns off and wont come back on until i put it near a light or press the power button 3 times. My question: how do I make it so the A.O.D. always stays on?
Thankyou for any help (^-^)

Get the repair done right? LG will do it right.
Proximity sensor lets the phone know if it's just a dark room or if you've flipped the phone over on the desk, or you have a flip case and it's closed. If the latter two, then no need for the AOD to even be on.

I get that but, I want the AOD to stay on. So how do I disable the light sensor so the AOD will stay on?

I don't think you can, which is why my suggestion was to get it repaired correctly ("get the repair done right"). Whoever repaired it botched the job.
