[Q] light sensor broken? - HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting

Hi guys,
Ill start with saying that my english is veryy bad
But my problem is:
I quess my light sensor on my hd2 is almost defect.
why?
When i start a call (or got an incoming call) the screen turns black
(as its suppose to be when you hold it to your ear)
But it turns black all the time, no matter how i hold it.
So i did a quick test, i called a number, and took a very bright light (100w) just next to the sensor. and after that, it doenst turn black for the first time!
So the sensor isnt working correctly anymore?
It is since my telephone has gone back to the shop for a new screen.
Can i make it better with software? Cause it works.. But only with a very bright light.... Or do i need to get back to the shop?
thnx

try a soft reboot and then if needed a hard reboot/factory reset. don't forget to back up the phone first as it wipes the phone

Sorry, i was forgotten to say:
Ive tried different roms, and even Android. Results are always the same!

That is an odd problem. Especially since the ambient light sensor is not what is used to black out the screen during calls. That would be the proximity sensor.
If you look very carefully just to the left of the speaker at the top of the phone you will see the proximity sensor. Do you have a case on your phone that may be blocking/interfering with this sensor? Do you hold your phone in a way that your fingers or hand may be close to this sensor?
Another thing to try is put the call on speaker phone, this should disable the proximity sensor and keep the screen on. If it does not then you may potentially have a hardware issue.

I haven't got something blocking the sensor. But because my screen was broken, they placed another one. (And since then it happend)
Ok, i did some tests..
I cleaned the screen very proper. And i was sure there was no spat of dust or whatever. so i called again.. And it worked properly!
But.. When i put my finger on the sensor.. (So its not 100% clean anymore) it turns black again. So its veeeeery sensitive..
When i turn on the speaker.. It doesnt turn black..
So conclusion:
It turns back way to fast. Only when the screen is 100% clean, and there is enough light in the room.. It works properly..
Aren't there any settings for windows or android to change the sensitivity? Cause this is very annoying..

Not that I'm aware of. It sounds like they didn't do a proper job of replacing the screen. The ammount of light in the room should have no impact on the screen turning on/off. Also, my screen is often quite filthy and I've never had that trip the proximity sensor. It is possible that the sensor was moved or misaligned during the repair.

Screen is NOT turned off actually by proximity sensor during phone call 2.1

Hi, may be it's just my x10i, but last night when I was making phone call in the dark I noticed that the screen is NOT turned off actually by the proximity sensor.
Yes the display went black if you put your finger in front of the sensor. This prevents any mistyping on the phone which is good. However, the back light of the display is still on. By this I mean, the screen is black but it's still bright, which made me feel very strange as it will continue to drain the battery. Anyone else discovered this? Any solutions?
hmm, mine doesnt turn off at all during calls, it will however turn off after 7-8 sec in call.
are you on 1.6 or 2.1?

I've noticed the same on both UK Generic and Global Generic 2.1, the screen goes black but the backlight is still 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.

[Q] Proximity Sensor during phone call

During a phone call, my proximity sensor doesnt seem to be sensitive enough. The screen turns off when I hold it to my ear, but when I pull away to look at the screen and interact with it, the screen either doesnt turn on or it will flash on and off again repeatedly. It seems that the phone cant detect that it is not near my head any more and should turn the screen back on.
Generally it wouldnt be a big deal since the screen does turn off when its held near my head, but when I needed to use the dial pad for a menu prompt it got really frustrating when trying to press in numbers with the screen switching on and off. (I just called Verizon CS recently and navigating through the menu was a pain with this screen going on and off).
I'm coming from the Samsung Charge which was very responsive: when you pulled the phone away from your head, the screen instantly turns on for you to press in keys or hang up. With the Rezound, it doesnt turn on most of the time and I have to press the power button (which will turn it on and then automatically off again...). The problem is alleviated if I'm in a very bright place (direct sunlight) so my guess is that the proximity sensor may not be sensitive enough to detect the difference between darkness and low lighting conditions. I'm sitting in a room with a 26W CFL lamp (so not too dark) and the Rezound has trouble turning the screen back on during a call when I pull the phone away from my ear.
Was wondering if anyone else exhibit this condition or if its just specific to my device (in which case I'll have to give Verizon a ring to get another replacement)?
I'm having the opposite problem. It unlocks itself a lot up against my head. My thunderbolt did this so bad I got a replacement thinking it was a defective proximity sensor. But it wasn't and I got in the habit of manually locking the screen on calls. But now my rezound does it but not as bad. I think htc sucks with proximity sensors cuz auto brightness is never programmed properly. It doesn't go dark enough compared to Samsung and motorola phones with auto brightness on. It only has about 3 brightness levels like in the HTC brightness widget, whereas stock Android has 5.

I'm having the same problem. The sensor would force the phone screen off as soon as I make a phone call. The verizon rep had me hard-reset while I was on the phone with her. The same symptom arises after the hard reset and the phone is brand-new.
I had to reset to get her to send me another rezound replacement.
On this replacement, however, I'm having the same issue again. My gf's rezound doesn't seem to have the issue.
I'm having a second replacement sent now. This is pretty annoying.
The interesting thing is the issue comes and goes. One day the sensor wouldn't respond, and other days it works fine. Although I would say that the issue deteriorates over time and never improves.

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..

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.
