[Q] Location notification LED

Hi all,
Ever since i started using CM7 on my DHD the LED being used for notifications changed from the right one (next to the speaker mesh wire) to the left one (underneath the speaker mesh wire) (i didn't even know there was one before that time )
Since i'm working as a carpenter my phone (and especially this mesh wire) gets all clogged up with dust pretty much all the time which makes it very hard to see the notification LED underneath it. Is there any way to change it back to it's original LED on the right of the speaker?? I'd prefer a change in command lines in stead of using an app.
Using Cyanogenmod 7.2 now (which works perfect i must say, but can't wait on ICS!)
Any help is much appreciated
PS. Anyone know why it changed from right to left? My guess is because the LED's on a 4G are positioned differently.

Euhh... Anyone??

You are right. I didn't even remember there was a led on the right. If I don't get back to you by sunday it means I haven't found an answer. You got me curious about this as well.

it is a proximity sensor on the right side....

It's then a proximity sensor, the thing on the right side which looks like a notification led?

correct, it is NOT an led, it is a sensor. it is how it tells if your face is next to the phone or not. start a phone call to your voice mail or whatever, and cover and let off of that spot with your finger, it will activate and deactivate the screen.

Ahh yes of course! Thanks guys!! It's just when i was using the original rom with Sense i could have sworn the LED was on the right. Hihi Silly me.
Thanks again! Yet another mystery solved!

[Q] Issue with Proximity Sensor?

Hi Guys,
Newbie here, wonderful forum and lots of tech stuff, kudos to every one who have contributed.:good:
Facing couple of issues with my NOKIA X, request your help pls!
Issue: Screen goes blank during a call, when using the phone without headset, & doesnt come back on, untill the call is disconnected by the caller at the other end.During this period, when the screen goes blank, it leaves me with no access to the menu, dialpad, etc and the call disconnect button doesnt end the call as well.
1) Turned off proxmity sensor in the "Phone-Settings" menu, it works properly.ie the screen stays "on" during the call and no issues with disconnecting the call, accessing the other dialpad options etc.
2)Also Turned on/off Automatically adjust screen brightness , observed that issue is intermittent.
Any leads would be helpful.Not sure about sensor calibration and tweaks
thanks

the screen supposedly to turn off during calls when it detect something near the proximity sensor ie your face when attending calls, this is to preserve power, and it should've come back on again when u bring it far from your face. this is default bahaviour on all smartphones nowadays.
but when it doesn't come back on again after u bring it far from your face after making calls, then thats a problem.
u use screen protector? a thick one and it covering the proximity sensor perhaps? from my experience thick screen protector that covering the sensor can interfere with its sensitivity.
the sensor is on the right side of the nokia logo infront of the phone. look closely and u could see it.

Thanks for your reply!.
Yes recently i got a matt finish screen protector on.,let me try taking it off and then observe if the issue pops up..Yes its a little frsutrating when the screen doesnt come back on once its moved away from the face & will have to wait till the caller disconnects the line from their end

Thank you mdfzhi, i took off the screen guard (yeah it looked unusually thick :silly and it seems to work at the moment, will monitor and see if the issue pops up!:good:
thanks again!!

search for screen protector that doesn't cover the proximity sensor, or if u cant find one that doesn't, cut yourself a hole in place of the sensor.
i'm using a thick anti fingerprint screen protector myself but its not covering the proximity sensor.

[Q] Screen goes blank when calling

I think I need some help, running stock just factory reseted phone but problem still there.
When making a call screen goes blank and I can't turn it on after that, can't hang up, can't do anything.
Is there any1 else experiencing this bug?

Maybe your sensor on the front is jacked up?

Nop had it tested in other app.

Try to factory reset it again, or you could investigate if any app you have is causing it.

Hahahahahahahahahahahhah GOT IT.
YOU GUYS WON'T BELIEVE WHAT IT WAS!!!!!!
It's my new tempered glass screen protector..removed it and now works perfect...

Haha, learned something new

Because I recently purchased one from Xtremeguard and it's currently being delivered to me. I sent an email to them and they claim that the tempered glass does not block the proximity sensor. I've read on another forum that this specific brand provided similar problems to what you experienced.

and also the missed touches on screen gets worse with tempered glass

nillkin tempered glass here without any issues. Can you post up a picture of your screen protector? Maybe the cutouts are different. I also had no idea on the screen protector that was installed by LG (which in different markets may have logos, but mine was clear, even had a tab to remove it, but left it on until I got my tempered glass one)

It's the sensor, not the protector

I have the same problem with my LG V10. I have NOTHING blocking the sensor. I just discovered that light level alone will cause the black screen.
I tried calling with a bright light overhead. No black screen.
I caused a shadow over the sensor (NOT blocking it, just a shadow). The screen went black. The same thing happened when I was in the T-Mobile store, with no block and no shadow.

Guys, I had the exact problem. And you DO NOT have to remove your protector, you just need to recalibrate the sensor. There is a tutorial, use the Search.

Did anyone manage to do this with Verizon?

Proximity sensor problem (SMMI test fail)

Hi, I've searched this forum and the Internet in general about proximity sensor problems but it seems like basically every problem that someone else had was fixed by removing tempered glass/screen protectors/cases/covers. I'm having a proximity sensor issue and I'm not using any screen protector or case.
This has happened twice now. Once when I was listening to visual voicemail, once when I was making a call. The screen goes dark and will not respond to any wake commands. Every now and then it will turn on for half a second when I hit the power button but then turns back off again. The first time when I was listening to visual voicemail, I had to hard restart the phone by holding volume up and power. The second time during the call, I managed to hang up the call in the half second the screen came back on, which ended the problem.
Right after that, I tested the proximity sensor using the SMMI test (calculator .12345+=). The test makes you put your hand near the sensor, then away, then near again. During the test, the phone immediately sensed my hand near the sensor except that my hand was nowhere near the sensor and there was nothing else near the sensor either.
I did a reboot and ran the test again. This time, the test finished correctly. The phone did not detect my hand until I actually put it near the sensor.
I'm running stock everything except I do have root(ZE551ML). I'm leaning towards this being a hardware problem and I've only had the phone for a week so I'm well within my replace period with Amazon. Is there a solution to this I'm missing or should I just replace? I'm a firm believer in troubleshooting first. Plus, setting up the phone the way I like again will be a huge PITA.
Thanks.

I would replace. It does sound like a hardware issue, and your better off getting a replacement instead of a possible pain for the life of your phone.

I get the same, and the flickering screen happened once to me after I I have just put a tempered glas protector on it ... removed it and so far no problems, but who knows.
I think the SMMI test works correctly the first time you start it, and incorrectly the 2nd, 3rd etc ... dont think it is a hardware error ...

Hi all, i have a zen2 with this same problem, i think doing sensor calibration can resolve the issue... but i can´t found how to do, by code, or by app...
Any body know how to do calibration of sensor aproximty?
Thanks in advanced!
Ps. I dont have screen os glass protector...

i don't having tempered glass or any screen protector. my proximity sensor is not working. Even i checked .12345+= but it gives error in proximity sensor. what to do? plz anyone?

same problem
Hi to everyone,
I have the same problem with the proximity sensor.
After a device reboot, the simmi test work correctly, but after some hours the test fails.
Someone know as I can calibrate the sensor ??
Thanks

I just fixed mine, cause I was having that issue for a LONG time now.
I actually just stuck a piece of paper in front of the light sensor part of the sensor window on the screen. It's the right side of the sensor window.
To be more clear, a while back my screen broke, so I ordered a screen online and changed it. Ever since then my prox. sensor didn't work, so I couldn't use the keypad during calls (the screen would go black).
My screen still isn't attached properly, so it's just being held in by the floppy protective case I have on it right now. This allowed me to pull the screen away from the phone a bit and slide a piece of paper behind it right in front of the light sensor. As soon as I blocked the light sensor then the proximity sensor started reading properly.
I got the idea because I was trying to clean the screen, thinking that it might just be dust blocking it or something. That didn't help, so I tried cleaning the sensor, but had the calibration test running at the time, and it instantly worked!
So I kept playing around with it and noticed that every time I blocked the right side of the sensor, it worked, but as soon as I removed the brush I was using to clean, it stopped working.
I stuck a piece of paper in, and BOOM, worked just fine.
People might want to build on this and maybe try sticking a piece of tape over the right part of the sensor. I haven't tried it, and since I finally have it working now, I really don't want to play with it too much and mess it up.
Hope this helps anyone else having this issue.

Hi all,
I am using zenfone 2 laser z550kl. Screen blackout during call and did not come up till the call is cut. I changed only the cover of proximity sensor and phone is working fine. Change the small rubber covering of sensor and it will work.
Hope this will help all if still using asus phone.

Screen unlocking during calls

I got my View 20 recently and I'm having a problem with screen unlocking during calls. The speaker is roughly at a 45 degree angle and I think so is the proximity sensor. And it only recognizes objects that are very very close to it. In other words unless I have the phone pressed against my ear (not touching or close to, actually pressed against it) it unlocks the screen during call, the notification panel opens up and I activate things I don't wanna activate... Once just as a test I made a short phone call and I made sure to keep the top of the phone pressed against my ear at all times and somehow it still unlocked the screen and the notification panel was open...
To make things even worse, because the angle is so weird I have to keep the phone lower than I'm used to (or comfortable with) and the bottom of the phone is way below my mouth which is bad too.
It's a real issue and I don't know what I can do to fix it. Please help me.
(And just as a side note I can't believe no one has mentioned this in ANY review - even if the screen doesn't unlock for them, the angle of the speaker is still weird and to hear the sound well you have to hold the phone lower than normally. It IS significant and I have no idea why this hasn't come up in any review or opinion on the internet).

Do you have any case on the phone? Sometimes the case may interfere with ur proximity sensor and cause these issues.

Nope, none.

I have the same problem. But without solution yet.

Disable Google smart unlock feature. And check.

It was never enabled.

The phone came with a preinstalled one but I removed it. No cases, no glasses, just a vanilla phone.

Any other ideas?
Or maybe I just a defective phone? Could other owners of View 20 say if their phones are fine?

It's not a fault... The sensor is on the top of the device instead of the front/screen so it happens... Poor design choice that's all.

Same problem noticed since day 1, found also no solution yet.
very disappointing.

Yeah, except it's not pointed upwards, it's pointed at a roughly 45 degree angle, so it should still work more or less fine. Maybe less fine than forward-facing sensor but still ok. And I doubt that thousands (millions?) of people who bought that phone experience the same problems and no one has mentioned it yet.

I'm on the second view 20... Sent first one back as I didn't like the warmish tint on the screen... Second one has a much cooler tone... Both do this with calls and my brother also has a view 20 and he has the same issue... Mine was from Amazon and he got his from carphone warehouse.
