Camera light stopped working

Hi everyone,
I got my Samsung Galaxy S2 on Thursday and yesterday(Monday) I noticed the camera light stopped working and I don't know why? Does anyone have any troubleshooting methods for a similar issue? I know it worked before, I had extended controls with the flashlight toggle and worked fine now I'm not sure if that's what messed it up. Even if I try to take a picture the light won't flash. I'm not rooted and have done multiple master resets to try and fix the issue. I really don't want to do a warranty exchange.
Also I noticed that when I plug my phone to Samsung kies it states that my firmware isn't upgradable??
Thanks I'm advance for any guidance.

If you've done a master reset a few times and its still not working if you take a picture or use a flashlight app then I would mark this one off as a hardware issue and exchange it.
From what I heard Kies isn't setup for our phone yet so that's why your getting the issue your getting with kies.

this used to happen when my battery was low on g2x, i let it charge and flash is good i think power saving settings override it. flash uses some power believe it or not... u werent at low battery right? only other thing i can say is if after a master reset it does not work take it back.. do me a favor try tiny flashlight + led its a flashlight app in market and works with most phones i also think it works at low power like below 30 percent see if it works, but first try charging your battery then report back

Update messed up S3 ... need help

ok so i finally bought an S3. i updated the software today from tmobile. but the update gave me 2 problems:
1 - the dialing rules dont work. for example, i call a chat line. after the number is dialed, the dialing rule dials a pause and 3 numbers automatically. this works. but when i try to dial additional keys manually, the dialpad doesnt work. this never happened in the previous version. how can i fix this?
2 - the battery drains like craxy. how can i revert back to the previous version?
by the way, is this the jelly bean update from tmobile for the S3?

It might help people help you to know what update this was ... ??
Look in your phone settings and see what you're running ?

directly from Tmo it only can be Jelly Bean. at the moment.
issues after updates on android is familiar. Factory reset your phone is the quickest way to fix it.
Turn off Google Now. My phone's battery goes back to normal now.

They weren't sure if it was JB, so I was a bit worried for them.
I wanted to be able to use Google Now's location features, and having set it to mobile data only (no GPS), it hasn't put a significant drain on the battery and I'm pleased with the results.
@OP, I was having horrible battery drain after the update, myself, but after messing with the settings and waiting a few days it's back to normal. Turn off Google Now if you don't want it and give it a few days - I don't know the technology behind it, but giving it a few days did seem to do the trick like others had said in the big battery life thread.

hi pennycake. but where do i find Google Now? i dont see it anywhere in the settings.
also, i found this link about how to revert back to a previous firumware.. please let me know what you think:
androidromupdate.com/2012/08/25/restore-back-t-mobile-samsung-galaxy-s3-sgh-t999-back-to-original-ics-4-0-4-t999uvalh2-stock-firmware/

If you go in the app drawer and find the "Google" icon, that will take you to it. You can also change the location preferences in "settings".
Personally, I wouldn't bother reverting unless there's something other than battery life that's really bothering you. Jelly Bean didn't have much in the way of big cosmetic changes and by turning off the location tracking, battery life should be the same as it was before. I don't think the average user will notice much of a difference.
See if the factory reset fixes the glitches you're having - when flashing a ROM (like the older firmware), you would want to do that anyway - it's possible to brick your phone flashing ROMs - not to scare you, but you might end up starting from a wipe anyway, if that doesn't go as planned.

hi pennycake. just to let you know, theres nothing worse that bothers someone than poor batt life. and other than that issue i got, i'm also having the dialing rules issue which doesnt let me dial extra digits manually after the dialing rule completes. this is very annoying.
i understand the risk in reverting back to the previous firmware. its just that if factory resetting doesnt work, i got to go back to the last fw. what i dont understand is why samsung or tmo would allow an update that disabled needed features.. and above all, mess up the batt life?

Trust me, I was pretty frustrated when I was losing 3% an hour on standby - and in use, I was just watching the battery go down another percent every time I glanced at it!
It's such a change from what many
People are used to that it ought to be better explained.
As for the dialer issues, I'm not sure if that is an issue with jelly Bean itself or not.
With every phone being a little different, sometimes things they don't expect can go wrong.
Hopefully you will get it sorted and be back to enjoying your phone soon!

NFC Issue

I'm running on CM10 nightlies (up to the latest). I can't get my phone to do anything NFC related.
I have NFC enabled in settings, beam is on, and I installed Z-Device Test from the Play store and it tells me the NFC is indeed active.
I have a Nexus 7 and a Nexus 10 which I can use to beam (they beam fine to each other). I took my phone and ran it along the front and back of both the 7 and 10 and it does nothing.
I've searched but couldn't find anyone with a similar issue. I even installed NFC Enable script for JB - no dice.
Can anyone help me out? Am I missing something?
Edit: I should add that I have a Laza extended battery with NFC and I've reached out to them. I also stuck the stock battery back in just to see if it was the extended battery and still no luck.

Does it work on stock?

Nope.

Same here, no luck with Nexus 10.

running PA v2.55 for some time now and happened to notice this issue as well.
really wanna use this feature (particularly after seeing holiday TV spots) but just cast that silly notion aside, considering how much more mighty my phone is than everyone else's.
hope there's a keen solution :beer:

Remove or Kill RILD process

Hey everyone. Long story short. I dropped my Galaxy Nexus in water and after trying for quite some time could not get the radio signals to work. It seems Wifi and bluetooth work fine, however it can not connect to any cell towers anymore. I have come to live with it however I still would like to use the phone for other things. Like a music player or GPS. My problem is since I have dropped it in water the battery life is terrible and i originally thought it was the battery went bad or something, but it seems that is not the case. I replaced the battery and am getting the same thing. After turning on Show CPU Usage I have a process RILD that is using up quite a bit of power. I know it has to do with cell usage, seems to be that its related to 4G. I do not care about this process and want to kill or remove it totally however everything I see that says a hard reboot will fix it, however my power button doesnt work either. I just want the process gone. Anyone have any advice? Thanks.

Turn on airplane mode and then post in the right section.

I am sorry I was not clear
I have tried airplane no, doesnt work. I have tried going into the build.prop and changing a few things I read in various forums to try and get that to work. I have also removed some .apk I thought might solve it, such as phone.apk, mms.apk and telephonyprovider.apk and still getting the same thing with RILD killing my battery in a matter of 3 - 4 hours from a full charge. I need a way to disable or kill this particular process

This was my thought too or even try a new sim and see if it fixes the problem with data all together. Assume the op already tried it but they didn't mention it

Sorry, but this site has some strict rules, the above being one of them. I will ask your thread to be moved. As for a tiny bit of help, did you immediately pull your battery and let your phone dry out for a few days before trying anything at all? This is paramount if you drop it in water.
good luck

Can't get NFC to work

I can turn it on but I get no little icon in the status bar as well as nothing happens when putting it against a HTC ONE with NFC enabled. Stock rom and kernel It's rooted and I've flashed a few different roms but I always come back to stock for the camera. I'd rather not flash a new stock again because I don't want to set it all up again.
I've disabled a few apps and stuff through app manager but none have to do with NFC.
other questions i want to ask but i dont want to start a whole thread for them. When i try to pair my S4 to the stereo in my car it says device full and I've done it before is this a problem with the phone or the stereo?
and does anyone have the link to a thread with all the processes they succesfully disabled without causing FC's?

I have a friend who has an HTC One, and we had a hard time getting it to work. I think one reason is the HTC One's NFC sensor is near the top of the phone, while the S4 is near the bottom. I didn't notice any icon, except when transferring files. I had better luck connecting to a Motorola Razr M, so I know that it does work. Also, you may want to make sure bluetooth is enabled, since some files are transferred that way.
As for trying to pair your phone to your car, you probably need to delete a device from the car. I had to do this with an old phone no longer in use, and then I was able to pair my new phone.
I hope you're able to get the NFC working. I bought some tags which work, and I'm trying to think of cool ways to use them.

Dude that is the first thing I noticed when I bought my S4 from T-Mobile. Seems like the NFC icon on status bar is for the AT&T model.. I haven't seen any other model with this icon. I managed to changed the build.prop to AT&T because I like the 4G logo and the carrier text appeared on status bar and says tmobile. This was something with att model as well. I noticed my NFC toggle logo changed to the one on status bar but yet it wont come on status bar... As of now i'm looking for a att rom to flash and see if it works but lately everybody have the idea on creating international rom... As of NFC working mine does

I flashed a stock Rom onto my s4 for this along with other reasons like turning on voice control FC'd camera but I still don't get NFC icon in my status bar. I feel like I remember seeing one on the day I got my phone but I can't anymore. I need to get somethin to test my nfc with

Maybe the NFC icon on status bar was in a oldest build. When I got mine a few weeks ago it had the latest MDL. A friend have a att model and her shows. Like I said even on the nfc toggle icon is different.
