IR in Galaxy SIII? - Galaxy S III Q&A, Help & Troubleshooting

i just found out about the IR beside the camera on my SIII.. and with a little search i got someone who's saying it's for removing red-eye effect..
but i guess i figured out what's about.. it's used for turning screen off when you're making calls.. just like in the figure in here:

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
what i want to know is.. does it have to be ON all the time? or is it because of my JB rom -_-
and second.. can we use the IR to send signals to other devices? and recive as well?
-i've tried to aim a remote control toward the IR reciver during a call but the screen didn't go off, i guess it's expecting a specific signal or frequesncy..

That is the proximity sensor and no we can't use it as an IR port.
The JB firmware you are using (XXDLI1 I presume) has a bug where the proximity sensor stays on all of the time.

like nodstuff wrote.
And, even if it were possible to use this IR as we wish, there is no guarantee that it uses the 38 kHz frequency range, that is the range used by most consumer IR devices and remotes. A few Sony remotes use 37 Khz.

when i put strong magnet near device - sensor data on compass change
Either the magnet is interfering with the devices hardware or it actually has a compass, just it needs appropriate software to work

There are cases that advertise a magnetic sensor that turns the screen off and on. I'm glad to see that there is some hardware to back this up and that it is not just a gimmick. Can anyone confirm that the magnetic cases do work with the sensor?

Microphone DB capped?

Hey all,
Can someone with a GSIII use a sound level (or decibel) program and let me know if the microphone is capped at a certain decibel level?
I have the Captivate (AT&T Galaxy I) and its capped at 82-83 db. I run sound, and it would be real helpful if the microphone didn't max out, or at least maxed out around 100 db's.
Can someone download a free db meter from the app store and just slowly turn up their stereo to tell me how many db's this is capped at (if its capped at all)?
Hey there Its capped at 89Db by the looks of things I use a handdryer hitting the mic port and putting it next to a speaker all of them capped at 89.
Heres a picture of it:

Well, that's a shame. I was really hoping this one was different, at least its a higher cap.
Maybe its a software cap that can be removed or adjusted. I will have to research.
Well I used sound meter lite im not sure what ones the best but yeah if rooted you will be able to increase it im sure.

It looks great but.
Ive broken the touch...every 1cm line the touch works, everything else is dead... The speaker is dead. A really good investment
1 problem...when I start the camera the phone crashes...
This is my logcat...I need to know if the camera is broken or its the rom
The phone reboots every 5mins...
I dont know if the rom is the problem or phone... :S
I cant install another rom because the setups need touch input except the one installed...reinstalled the one but still the same.
Nobody interested
It was the roms fault lol and the connection to the top unit (speaker sensor notification led) was not good...
The phone is now fully silver/white...ill make pics if interested
yes show some pics...
I'd like to see some pics too.
gone...far far away, bouth an m7 :/

Does everyone have the "rainbow effect"? It's deal breaker?

Just brought it, i really like it in all aspects except the annoying rainbow effect, i can even see it without tilt the tablet, especially in landscape, just wondering EVERYONE have this problem? after some time of use you get used to? any way of fix it?
I was thinking of change it but it doesn't make sense if all units are faulty
Rainbow effect:

I am unable to access your screen picture but my tablet is perfectly normal and has none of the aberrations you describe. I was in a shop yesterday and handled the two display models and they were fine too. So I would suspect a fault with yours.
Here are the pics http://imgur.com/a/mpuTI#0
So your tablet doesn't have any of this when you tilt it?
I noticed a rainbow effect when I first got mine, but now I don't see it at all unless I really look for it.

No, none of that. Using the same Google page,I have tilted it in every direction and it is a clean high quality IPS screen with no artifacts.

Change Selected Microphone from A Software?

Hello Guys,
My friend got a samsung s3 9300 and his mic for "phone calls" is not working. But, we can record voice which means there is another mic (next to speaker )
Is there a way to activate second mic (which used for voice record) as main ?
Kind Regards.
Here is the mic places on board

Firstly, make sure the hole isn't clogged and nothing at all is stuck in there.
If you are running a stock firmware you can try flashing the firmware again to see if that solves anything.
If you are using a custom rom you might want to flash a stock firmware and test the mic again. Some custom kernels can cause the mic and earpiece to stop working as they should.
If a fresh stock firmware doesn't solve it then you would have to have the mic replaced as there is no way to switch them with software. Even if you could they are directional microphones, which means they only pick up sound from the direction they're facing. Your voice will be too feint in calls, especially outdoors.
