[Q] Blinking/Flashing Red Light from Proximity Sensor on GS2 - Galaxy S II Q&A, Help & Troubleshooting

I just bought SSGS2 last week, and i noticed that when i make a call, this the red light will be blinking/flashing. When I compare it to other SSGS2, all of which will have a red light on when make a phone call (not blinking/flashing).
So I was wondering if anyone had the blinking light?
As far as I am concerned, it does not affect usage just yet.
But who knows...it might be a sign of inferior sensor.
Thank you.

Use your phone in the dark, you will see a very dim red glow where the proximity sensor is.

Thank you.
Should it be blinking? or stay on while calling?
Mine is blinking. Those of my friends stay on

can some one please advise, Proximity Sensor should be Blinking/Flashing or solid On when you are on call?

It's blinking for me as well... Why are you guys so paranoid. Is it working? Yes it is.

It blinks extremely quickly, seems like 20 times a second. I can in indoors lighting clearly.

not paranoid mate, just want to find out if this is normal, yes so far this is not affecting performance.

Well my so called proximity sensor "red dot" keeps flickering while in standby/phone locked. I understand it's suppose to be on while on a call etc. but what when the phone is lying idle?

same problem!

I have the exact same problem since yesterday.. have u solved it ? pls help!! it's really annoying
kindly email me if you have method to solve it . [email protected]

I dont know if this is relevant but I've had both the i9100 and the i9100G. On the G variant the blinking of the proximity sensor was pronounced and noticeable.. whereas on the international variant I've never yet noticed it blinking or staying on. Maybe you have the G variant?

If you have Viber, uninstall it! I had that issue few days back. actually I just uninstalled it because it was draining my juice but the then after getting rid of the viber app my proximity sensor was no longer blinking like crazy.
Since I dont use Viber I unistall it.

Soft key backlights

Hi all
I am having an issue with the backlights behind the soft keys. Sometimes they light up, other times they do not.
Is this a common issue? Is it possible software related, or is it definitely going to be a hardware problem?
Many thanks
James

i started to get this also on CM7 but i also changed the backlight density to lower then it was from 20 to 1 so i think that might be the issue for me
I have WTFOMGBBQ backlit softkey lighting control on my aria and inspire, but ATRIX is okay (actually, it's always on when the phone is on).

I think I may have been embarrassingly stupid here. I did not realise the lights behind the buttons were connected to the light sensor. It is possible I have just been using the phone in light conditions right on the cusp of the on/off and hence, it can look a little odd.
I will keep an eye on it for the time being and assume it was me, not Motorola's engineering, at fault.
Thanks for the responses.

LED as notification indicator?

So I just noticed there is a red LED on the phone, However I've only seen it enabled whilst in call (Am I the only one who hasn't noticed it before?) So anyway, I'm curious to weather someone would be willing to go about and help trying to be able to have it on when you have a notification, Or if there already is a mod? Anyway, Thanks
That's a proximity sensor, not led

It's a proximity sensor,this sensor ensures that the screen turns off when you are in a call.
Oh Damn, Dissapointed Would you be able to have it on anyway? But I guess it'd kill the battery?
That Red LED is barely noticeable unless you are in complete dark!

[Q] Dat Light...?

I'm unsure if anyone tackled or even noticed this one yet, but I noticed that after I unlocked the bootloader via htcdev.com, whenever I make a call, there's a little red light that sits above the HTC branding (left of the notification LED) that flickers repeatedly whenever I make any phone calls. Is this a unlocked bootloader indicator, malfunction, or normal function of the phone? Also, can someone tell me what that light is for if it's not an indicator of a call?

I don't ever get the red indicator light unless my battery level is low.
In fact I don't have any LED light while I'm on a call at all.

I'm not saying the notification LED. It's a separate light to the left of it. It's located conveniently right above the right side of the T in the HTC branding. It's very very faint. The only reason I noticed it was because I was in the dark and I pulled the phone away from my face to look at it.

I'm in the dark right now. I just made a call to my work phone. There is no light.
That's a sensor. It turns the screen off when the phone is by your face..(having a brain fart of what that sensor is called) lol

So when that sensor is active, you can see the red flashing it does?
Edit: Well, you seem to have won the cookie. I don't know why my proximity sensor is actually visible. I just tested it with my thumb. Turns out that that is indeed the proximity sensor.
Mine does the same thing only its completly random. I'll look over and it'll be flashing. I decided to just ignore it a few weeks ago.

Mines doing it to, its really very faint and wouldn't have noticed it had I not read this.

I noticed this a while a ago it is the proximity sensor, its not next to the left of the ambient light sensor and it is NOT the led!!, go into a dark room and make a call it'll start blinking...or any app that uses proximity sensor...Also if you have the option of pocket mode it'll probably be running all the time but i'm not sure, it should technically run when you receive a call, but you will definitely notice that it'll blink very very rapidly while you're in a call...proximity sensor!!
Whats weird that I noticed also is that when my HTC amaze fell on the floor board of my truck I reached down to pick it up and passed it in front of my Radar detector the L band went off on the radar detector I though maybe a cop out but nope every time i put the phone in the radar detectors view it started going off, pretty weird just wondering if anyone can explain that, it might be the reason its giving off that red glow
It emits infrared light. Some peoples' eyes are better attuned to see it than others. In other words, some people cannot see the light at all, and other people can see it just find - it all depends on how sensitive your eyes are to the infrared spectrum.
yeah i thought i was the only one with this problem. whenever i make calls the light goes crazy even after the call!
hey so after reading this, because i was also trying to find out what it is myself.. i now know what it is..
but recently i noticed that my phone freaked out, and shut itself off, and that red light stayed on.. my phone wouldnt charge nor turn on until
i took the battery out and out it back in.. has that happened to anyone??
Yea I've seen it to

Xperia P proximity sensor glowing red

Hi everyone, has this happened to anyone else ?
Since a few days now i see that my proximity sensor is glowing red al the time, it is very very low when the phone is unlocked and a little bit stronger when it is locked ...
I've found a video on youtube where a guy has almost the same problem, but at his phone it is glowing in another color and mine is glowing red, he says that viber makes a bug and that happens at him, what could be the possible app which makes the problem at my ?
proximity sensor glows
I had the same problem, thanks even i uninstalled viber and the glow switched off.

Both screens turn off from time to time

Hello. I have weird problem on my Lg V10 H901. On 2 to 3 days it happens for both screens to turn off, and you can't wake up the phone with double touch or with power button. And I'm sure that the phone is working because I can feel vibration feedback when I press and hold power button to go in to power menu. The cure is to pull off the battery and put back on and start the phone. For two or three times it happens to show white screen with little colored dots on it when you power on the phone. Otherwise the phone works normal. . No glitches, no heating, nothing. It just go off when it sits on desk and won't came back till you pull off the battery. I don't believe it's a screen because when it happens the both screens go off. Could it be the motherboard, processor or memory, or it's something wrong with proximity and light sensor? Any suggestions?
I had this problem as well until my proximity and light sensor completely stopped working. The sensor is not detected anymore but the issue stopped after.
I don't know about the cause but it could be because of proximity and light sensor.

Thanks for the reply. I am suspecting proximity and light sensor also. I am thinking to order a new one, it's like 9$.

By the way, I feel it is better without proximity and light sensor. Many problems were fixed after it was obsolete.
