Its the light sensor and next to that is the proximity sensor.

But i only notice this after i root my phone, can someone reproduce this?
Edit:- something weird happen, after i end all running app using systempanel, the light suddenly gone!!!
Can anybody confirm what is this?

Can someone give me the best settings for the camera to work during night pictures? Haven't been able to take a single nice picture at night. All dark, blurry and the damm led light doesn't help.

try to reduce or increase the +/- sign, i forgot what it called, and test it out yourself
Thanks, already had tried that but still looks wired. Guess we'll never get good nighttime pictures with a stupid led flash.

Vibrating when Camera or Torch opens

Hi guys, just like the title says, this is my problem.. when I open Camera app or turn on Torch, something near camera lens starts to vibrate and I have to bang it. I'm running CM 9.1 (aosp camera app) and Chameleon 1.3 (stock sammy app). At first I thougt it is caused by the CM, but why also on Chameleon ? Will this problen disappear if I flash original stock firmware ? I wasn't experiencing this before I started to play with flashing so I hope the phone is not damaged in any way..
thanks

My phone also does this sometimes. Have always noticed it. A lot more so with cm9 though.
Haven't found any answers. It also seems to get extremely hot.

Anyone? Is this harmful for my phone?
I have noticed.when.the.torch.is. on if i have the screen facing down it vibrates constantly almost every time.
The moving part is the focus module of the camera.
It, however, should only move for a short time.
It usually only clicks for me.

It vibrates until i bang the phone gently on my hand. When vibrating the camera gets extremely hot
I think this is a hardware fault as it has been like this since i got the phone in november 2011, i have tried pretty much every kernel/rom/modem out there. So i know it is not software related. Unless it is canera firmware? I have updated this too.
Edit:
Since i have had the phone it has never vibrated like this whilst using the camera for pictures.
Always when i use the torch. 90percent of the time when i face the screen down with the torch on, it has rarely done it with the torch facing down.

Ambient/Proximity sensor emitting dim red light 24/7

I have a strange problem. My phone's ambient/proximity sensor seems to be glowing dim red all the time. its really visible in the dark. it only starts to glow when the phone has booted into android. during the booting it stays off.
I understand some people will think I am confusing the LED for a sensor but let me assure you thats not the case. I am actuallt talking about the sensor situated on the right side of the earpiece beside the "SAMSUNG"'s letter G.
Its from Viber. Uninstal it.

Thank You, That seems to fix the problem. However whenever I use the messaging app the dim red light comes on again.
Furthermore, Is this dangerous ? as I would just ignore it and keep using viber if its not a big deal.
Thanks

Nothing dangerous, you will see the sensor light in messaging app because the very same is used for Smart call feature

Problem with hard key's.....

my hard key lights are not working in th3bill's cm10 4.1.2...somebody Pls help me
Sent from my MB855 using xda premium
Have you tried flashing the ROM a second time, after a full wipe (if possible)? Sometimes these things just have the tiniest little glitches and nobody can figure out why they happen, yet a second flash miraculously fixes/solves whatever happened the first time out.
I've yet to see anyone mention any issues with the buttons - they're still considering "soft" buttons, however. As soon as I saw "hard keys" my thought was problems with the power/sleep, volume, or the camera button and not the capacitive touch ones under the display.
Just so you know...
Also, I note you say they're not lighting up - the real question then becomes are they still functional even though they're not lighting up?
Yes the soft buttons are functioning...but not lighting up....but few hours ago it was fine....but now it's not lighting up....maybe some setting issue....anybody know how to solve this in setting's mode?
