So when I'm on a call there's a red rapidly blinking LED light though its very dim. Anyone else notice this? Any mods?
It's the proximity sensor. When the phone is close to your face or turned upside down the screen turns off.
I had this happen last night, but I wasn't on a call at all. I just happened to see it (the room was dark so the dim LED was visible). It persisted for a while but by morning was gone. Battery wasn't low at that point (though it had been earlier in the day) so I was hoping there'd be more insight about it today. =)
First time poster, though been a regular lurker.
It seems I have a slightly dodgy proximity sensor. Have checked with one of the proximity sensor apps and while the sensor detects if I have my hand over it, it is very unreliable when I take my hand off. It can take from anywhere from 1 to 30 seconds or sometimes never.
While ive been through other threads where people have a completely failed sensor, does anyone have this intermittent problem. Also is this a hardware or software issue.
Im currently htc-dev unlocked running Pacman v15.0.
Out there is a tool for recalibrating the sensor, but you would need to be S-OFF I think and it's done with a service tool (a special PG88DIAG.nbh)
Let me know if you are willing to try it, but it is VERY dangerous if you do the wrong things.
I had the exact problem from the very beginning. Got a phone and the very next day had a screen protector applied. For a few days proximity sensor created problems. The screen would go black when the call started, but until the call did not end, there was no way to bring the screen back. So, I used an app just like yourself to check and saw the same thing happening. Ultimately read extensively and realised it was due to screen protector. Took a scissor and cut off the protector above the sensor. A few months later when I had a new protector (of a different company) applied the same problem reappeared, so I had to cut it off from the top. Except that this time around I was sort of expecting it. I hope this help! :fingers-crossed:
I had the same problem and it continued no matter whether i remove the protector or cut the portion....im unable to most awesome ROM's.......only n sense 4.0 im able to re turn on the screen using power button.if there a way to completely disable this turn off during calls irrespective of the ROM its highly appreciated......
Looking forward for the solution

An update to my situation.. I ordered a new proximity sensor on e-bay and have replaced the same on my phone now. While I was at it, I cleaned up the window as it was pretty grimy and could have been the source of trouble. Also cleaned up the contacts with Isopropyl alcohol. End result.. Im still having the same problem!!
Im pretty sure now that its not a hardware problem and has to do with the calibration. What I have noticed that the sensor works fine in bright sunlight but not when there is less light around. Also am not using a screen guard!
Would it be possible to guide me to the right tools to recalibrate please?
Sorry, I haven't done this myself, but I'll search a bit how it's done by HTC.
They are using a special holding station where the devices are calibrated.
Has anyone else experienced the phone when first turned on being bright only to have it flicker after about 5 seconds and get a bit more dim? That's my biggest complaint with this phone. I have found out last night that while I had no lights on in the house it was not happening. Tried it again this morning and same thing. Works fine. But I turned on the lights and it happens again. I have the display at 100% with no automatic brightness. I hope it's not a hardware issue and just software.
My screen goes black when I am in a phone call and it does not turn on unless I hold the power button or something like that. I have already went to the proximity settings to test that it is working.
Any ideas?
Firmware version? Seems to be a bug in last firmwares. Also had this issue some time. Now it seems to be gone.

.In the process of backing up my phone atm to try a factory reset. I'm on latest T-mobile version though.
How did you fix yours?
Bump. Anyone? Is there a fix or is my sensor faulty? Because if it is I can still send it back in for a replacement. Sometimes it will work fine, and sometimes it won't.
I've got similar problem. When sensor is activated, it's keeping activated even if nothing is in front of sensor, so I have to wait for other side to end a call.. any suggestions?
EDIT: problem solved-> I just cleaned the glass on proximity sensor, maybe some dust was there

I also have a problem with phone's proximity sensor. With me, it shows some signs of work right after i boot up the phone. In service menu (*#*#7378423#*#*) -> Proximity switch starts with On value and then goes Off, On, Off, On.. a cycle of at least one minute. The interesting thing is when i cover the sensor it stays On, which means it detects its working. I suppose the sensor is faulty, as I tried several suggested methods to resolve this issue: pressing firmly on top of the sensor, factory resets, reinstalling the software with Sony's PC software kit, some applications from Google market, etc. None of them helped.
As I bought my phone 2nd hand, I see the upper speaker is pressed on its left side a little bit, as if the phone was dropped exactly on this spot at the speaker (which I find is almost impossible, as the front panel is perfect without scratches or anything) or somehow it was pushed with some sharp object. I explained this as it might have a link with the proximity sensor issue, or it may not be connected to it, not sure.
Greetings.
I just picked up the Verizon variant of the V50 and have a question, hopefully someone with a V50 can help me out. My proximity sensor, which is supposed to only be active during phone calls to shut off the screen, seems to be responding to darkness. If I'm in a lit room and the screen is locked, the phone shows the "Always on Display" like normal. However, if I turn off the lights, the screen goes black, the fingerprint sensor does not respond to touch and I have to press the power button multiple times to get the screen to activate. If I turn the light back on in the room, the AOD comes back on and the fingerprint sensor responds to touch.
I took a trip to my local vzw store hoping they would have a V50 on display to test this since I don't know if this is a phone feature or a defect. I'd hate to go through the hassle of swapping phones only to have the new one do it too.
I do have a screen protector on the phone but it is not covering the proximity sensor.
Can anyone with a V50 test theirs to see what happens and let me know? I'd appreciate it.
I just tested this on a Verizon LG V50. Almost pitch black while on a call:
- Screen blanks when I put it up to my ear
- Screen lights up when I pull it away.

Mine works fine when I'm on a call, it's when I'm not on a call. What if you have it just sitting on a table and you turn off lights and make it completely dark in the room? Does the aod turn off or stay on?

Or try this. Have it sitting face up on a table with the AOD on and put your finger over the earpiece/proximity sensor area. Does the display turn off? Mine does and I don't think it should. My V30 didn't.

Sorry, it was late when I responded and I neglected to mention that.
When not on a call, in pitch black, covering the screen doe not blank it out. Only when on a call does it blank when you cover the proximity sensor.

I appreciate your help. What about in regularly lit room? With phone showing the always on display, if you cover earpiece area, does display turn off or stay on? On mine, just sitting on a table in a lit room, and it's showing the clock on the aod, if I cover the earpiece display turns off. Sounds like I might have a defective device.

OK....Let me apologize once more. I missed the AOD part.
AOD turns off when covered regardless of light or dark environment. You want this to happen. The regular home screen does not blank except during a phone call.
You want the AOD to blank such as putting it in your pocket. This is an OLED and they burn. I have a Galaxy S8 where you can see that I used Waze a LOT. I would say that this behavior is normal.
Sorry about the confusion and missing where you asked for AOD.

No problem, thanks for your help. Can I ask one more thing? With the AOD on, with phone sitting face up with no obstructions anywhere and you make it pitch black in the room WITHOUT covering or touching the sensor. Does the AOD stay lit up or turn off?
In that scenario the AOD stays on.
Went in to a room with AOD on. Turned lights off....AOD stays on.
Turned the lights back on and then off to test. It stayed on.
As soon as I cover the proximity sensor with my hand, it turns off.

I have the same problem. And I have already discovered that it is clearly a failure of the proximity sensor since with a sensor testing application it tells me that I have an obstacle 0cm from the screen. Have you managed to fix it?

Try this. Ensure there is no screen protector over the selfie camera. Either cut a relief or use a pre cut protector for v50s/g8x. It worked for me.

Well this is most common issues with low level refurbs.
Please use this App - it will fix the issue.
