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

Galaxy Nexus LED flash has issues

I've had my galaxy nexus for a full 2 weeks and only recently I've noticed problems with the camera LED flash. (not the notification LED, the camera flash on the back of the phone.) Pretty much the LED on the phone will stop working most off the time for no reason at all.
I try to snap a pic with flash turned on but it won't do anything (only takes the pic but no flash), same with the camcorder and third party flashlight apps I've used. I actually managed to get it to work a few times but I havent been doing anything differently so it seems like it works at random.
The LED flash has not been functioning properly for the past 2 days and i even tried a factory reset to fix this but no luck unfortunately. Has anyone else had issues with this, or have any advice on how to fix this? i'm hoping its not a hardware issue.

I've had no issues with the flash so it seems you indeed have a hardware issue... TeslaLED works for sure, so you might want to try it though. Some other flashlight widgets seem to have issues with the phone.
You should be able to get the flash working at least in the camera app and in TeslaLED.

I have just tried Tesla led, it's not working on my nexus, but flash working well when shooting. I'm confused a bit.

TeslaLED working fine for me too.

I would bring the phone back to wherever you bought it, show the issue to them, and they should replace it. Sounds like a hardware issue, I've had the phone for > 3 weeks and my LED flash has never failed to turn on.

Reboot. Go into the ICS stock camera app. Manually turn on flash (force on). Take pictures. If the flash doesn't turn on every time, something is wrong with the hardware.

Strange behaviour you think only your Gnex has

I browse xda alot and stumbled up on many weird issues.
Maybe this thread could be an advise-thread like "don't use your Gnex with a Netgear N Wifi AP"
If there is no interest in this thread, just let it die
This is not a thread related to a specific ROM. More for flashaholic people like me who encounter little issues that occur on many different ROMs.
I will list my issues so you get an idea why I started this thread:
- If I connect my Gnex to the charger and use it, almost every time PIE will break and I cant navigate anymore (AOSP-PIE) - I have to reboot my phone.
- If I connect my Gnex to my schools WiFi (CISCO Hardware) I have constant data-download activity and my battery drains in no time
- Sometimes if I connect my Gnex to the charger it behaves like it gets plugged in and out very frequently
- At home, connected to my WiFi (Netgear Router) I have to constantly wake my Gnex to receive new messages (Whatsapp, Mail, etc.)
Maybe we can help each other with tips?
- cheers

I have none of these issues but one. The last one. I thought I was the only one! It happens randomly to me.. I tried to find a fix but havent come across any. Nice idea for a thread it helped me already

I have not faced any of these issues. Been changing ROMs ever since the day I bought the phone (A year and a half back).
That charging issue alone cropped up once. But I was able to fix it by pushing the pin in the charging port up by a bit using a safety pin

1. My volume down is busted. Pressing it on normal mode, nothing happens. In Safe Mode, it works though I have to press real hard. Due to this, cant do screenshots anymore.
2. I can connect this gnex to my computer fine but the phone does not detect the charge.
3. Much much more wakelocks when using original battery compared to a china branded replacement battery

well, that's interesting! I'm planning a replacement because my phone is two years old and so is the battery.

While using certain kernels with Trickster Mod and "set on boot" option, I get a reboot if the screen is off when Trickster applies it's settings. Took me a long time to figure this out. If the screen is on when Trickster applies kernel settings it works just fine. Never could figure out why this happens, but I use tasker to keep the screen on for 2 minutes after boot to prevent it.

[Q] Led Notifications not working

Received the M8 a few days ago and the LED works OK as it lights up on charging...BUT that's it no missed call or Email SMS etc.
Looking around various forums it looks like there are some issues probably software related as people have exchanged phones and still had the issue.
My question to you on the International version is anyone having these issues and if so has anyone found a fix.
Thank you

I had the same issue; so I factory reset the phone. But this time around, I didn't restore any backup and started fresh. Seems to be working so far (and it's been 2 days).

Thank you I will try that when time is permitting...most frustrating though on a new phone and cannot see any apps that were restored from Google that may have been in conflict.

I'm going through the same problem...

Same problem here . .works while charging but not on texts etc . . Did restore a app from Google on setup but can't be bothered with a factory reset wonder if this will be fixed via update?

Can confirm this method works but should'nt have had to factory reset. I'm now resetting up all my phone . .just hope it doesnt happen again.
Must be back from google bug somewhere that messes up the LED's from working ?? But dont really understand how it would . .

I had the same problem. I read on another forum that if you install another launcher the led stops working for notifications. When I first setup my phone restored apps and one of them happened to be a launcher. I did factory reset did not restore any apps and notifications led started working again. I'm not sure if another launcher had anything to do with it but the fix worked for me.

For me the notification LED works from day one, did not had a problem, i did restore my apps from backup but i never used any other launcher so i cannot confirm that is the problem. But i believe it must be app related as its working for some and not for others, usually hard reset without restoring app brings it back. Strange...

When I was migrating my note 2 to m8 must have copied a new launcher . I have factory reset and installed backups manually all is good now

This may or may not be related, but is there any way to keep the LED light flashing when you have a notification and not have it turn off after five minutes?

Everything I found says that there is no setting on the phone to change that. It may require a developer to patch it or give us some instructions on how to extend the time.

I'm also having the same problem with the LED notification. I really don't want to do a factory reset so i'm still hoping that there is a solution to this. The LED lights up during charging but does not light up at all for text message or email or other notifications. I'm using nova launcher so some are saying that it is because of these third party launchers that is the cause but i'm still wondering how can that really effect the LED. I hope somebody can really enlighten us on this.

I had this issue but only for missed calls. Other missed things would still notify. I did a factory reset and still have the same problem without doing any backups!!

I have the same Issue but I really don't want to reset the phone.
Still hoping for another fix....

I had the same problem on the day I picked it up. Read about the factory reset and as it was my first day with it decided to go for it.
That did indeed fix it and the led started working as it should..... Today however, they have stopped again. I haven't installed any other apps and a power cycle doesn't help.
Don't want to reset it again so am hoping they fix this soon.

Any news on this? Really missing led notification
Verstuurd vanaf mijn HTC One_M8 met Tapatalk

I installed Light Manager and i seem to be getting lights, however im getting random notifications with a vibrate and light when there is in fact no notification.

Mine seem to come and go, they worked after the factory reset for a bit I then noticed that they had stopped .
Now they are working again.... Seems very strange.

I dont get any green light notifications while my phone is charging, i would at least expect the screen to come on.

Notification LED only works if your screen is off. The LED for charging will illuminate no matter if screen is off or on

Strange wifi problem after kitkat upgrade?

After upgraded to kitkat, I noticed wifi icon at status bar will be missing after many days. Wifi will indicates as off and it couldn't be turned on. YET wifi is working fine. The only way to clear is to reboot. Anyone seen this?

I have the issue too. Anyone have any idea how to fix? Thanks.

I noticed the same thing too. Turning airplane mode on and off fixes it for me. I just got the tablet a few days ago, so I havent done much testing, but do you guys have " turn wifi off during sleep" setting on in the advanced wifi menu? I was suspecting that to be the culprit.

I realized this thread is nearly a year old, but I just bought this (used) Note tablet, and experienced the exact symptoms as described by the other posters. The wifi issue happens almost every time my tablet sleeps for more than a hour. Toggling airplane mode on/off fixes the issue, only temporarily, until the next sleep. I am wondering if there are any clues to what causes the issue.
Is it a bug in the factory rom, or something that I installed?
Here is the info of my tablet:
- US model SM-P600 (XAR), with latest stock rom UEUCOB1
- Rooted by TWRP 2.8.5.1
- Xposed installed with these modules:
Wanam
No Wake of Charge for S5, and
App Settings (only change rotation setting for one 3rd party app).
I am considering do a factory reset and setting it up again from scratch. But I want to hear if others are experiencing this issue even with 100% stock (non-rooted) rom. By the way, the issue only happens when you set Keep Wi-Fi on during sleep to either "Never" or "Only when plugged in". I would really appreciate someone with non-rooted rom letting me know if this happens to them when they set their tablets to allow Wifi to sleep with tablet.
