[Q] LED Flash Lagging with Applications - Galaxy S 4 Q&A, Help & Troubleshooting

Hi all,
I bought a Samsung GT I9500 and I noticed that whenever I put an application such as an LED Flash Light or LED Flash Notifications (like flash blink) for some reason or other it slows the whole phone down it practically freezes up entirely and after a long wait the flash finally comes on. This only happens the first time if I was to put the flash off and on continuously it would be a bit snappier but would still be noticeably lagging. This doesnt happen with the camera btw when taking pictures the flash works just fine. It only seems to be occuring like this when another application is involved.
The phone is still under warranty do you think I should ask for a change of phone or do you think its a ROM issue? Although it is occuring with both stock and modified roms (im using WANAM rom).
Thanks

I work nights so I rely on the torch in my phone for all kinds of things. The SOLE reason why I cant use custom kernals is my ultra bright torch app crashes on anything but stock kernal.
This is your answer - flash the repackaged stock kernal from Wanam and it should be much better. I had the exact problem you did an now its fine.

Hi thanks for your reply,
I reflashed the repackaged kernel but the flash blink application keeps lagging or in some cases it doesn't flash at all probably because it takes too long for the flash to start up only the camera application works flawlessly with the flash so far. Any other suggestions guys? Or perhaps a problem with the handset?

[Q] Touchscreen becomes completely unusable when opening camera?

Hi!
I'm absolutely new here (and to Android and everything about it) and i've only made a couple of posts in the noob thread. I felt like this should be a thread of its own due to its abnormality.
I've only very recently rooted my phone (i9505, 4.4.2) a couple of hours ago using the towelroot method. I have not flashed any custom ROM yet however I do have some Xposed Modules installed.
i've only run across some problems like repetitive rebooting (fixed) and faster battery drain (hopefully fixed by tomorrow).
However, I have one problem that doesn't seem to have any solution whatsoever anywhere in the internet; it wasn't even mentioned once.
Whenever I open the stock camera app, the touch screen becomes completely useless. I cannot touch anything; the settings, shutter, view finder to focus, absolutely nothing. The camera itself is not broken, I can still take pictures with the volume rockers. Also, I know not the entire screen is broken because one of the modules I have installed is SwipeBack, which lets me swipe from a corner and it goes back and it still works perfectly fine.
I've tried rebooting the phone and force stopping the camera but nothing has worked.
The only suspicious thing I've done is backup and uninstall all the KNOX apps, which should be no surprise.
Now I'm not particularly bothered by this as I barely use the stock camera app anyway, or any camera app besides Snapchat. I don't use my phone for taking pictures much, but it still is quite annoying.
Is there any sort of fix to this?
Thank you very much in advance!

Camera Flash Doesn't Work

For no reason my camera flash sometimes doesn't work. When it doesn't work neither will other camera app flashes nor apps to use flash as a flashlight. A phone restart fixes it but by then of course the scene you wanted to photograph is gone.
I am stock VZW 4.4.4 never rooted in a month old Asurian replacement phone. I seldom use flash so I don't know how often this issue occurs. I never happened on my original note 3 however again I seldom used flash. Also I have read this happens to many other people but no measure to cure or prevent it other than the slow restart process.
Anybody know a real fix? Thanks!

Motherboard problems/Lollipop only

Hello guys,
I'm currently having issues with my phone since I've dropped it in a pond outside, and I guess it's the motherboard that is affected.
I cannot charge my phone (I use a desk changer + another battery), the flash is working only for half a second while taking pictures so I need to manually set the ISO, but those problems are not so important.
The reason I write here is because everytime I flash an official or any other touchwiz based LOLLIPOP OS, the phone is getting through a "plug/unplug". I don't know how to explain, it simply says that it's charging, then after a few seconds it says it's not charging, and so on, WITHOUT having it plugged.
Is there any way to simply delete these instructions from the OS? The phone is working flawlessly otherwise.
These things only happen when using official or touchwiz based LP, the KK ones are working as they should, and it's a bit weird because only with LP I have these problems. Also, if I flash some CM based OS, it's working flawlessly.
Please help.
Thanks in advance.

Galaxy S4 I9500 Lag

Hello.
Recently i was in Prism BB v16 and had no lags at all (11GB pit), but yesterday i tried to go back to Stock Lollipop (with 8gb pit) and i tried both HOA7 and the new HOD4 firmware, and they both were extremely laggy. I couldn't install almost any apps, camera wouldn't work, when i lock the phone and try to wake the phone it took 30+ seconds to show the lockscreen. And btw all the roms i try lag like this now (Aurora S6 port, Prism BB etc..)
Now i'm back to stock 4.4.2 UGNJ1 and it's working as it did before with the only problem being when taking 4-5 HDR photos, phone shuts down itself and the only way to turn it on is by taking out the battery.
I've flashed alot of Custom Roms (100+) in the past but never experienced any similar problem until now.
What could be the problem ?

Weird Camera behaviour - Camera not working

So, I'm experiencing this weird camera issue. The phone says taht it could not start the camera or that the camera is already in use. But then, if I turn off the device for something like a day or two, once I turn it on again the camera starts working properly until I reboot the phone. I already tried to flash stock rom, firmware, whatsoever, but it didn't work. I also tried may custom roms, but the behaviour is always the same. Would you have any suggestions? Right now I'm running A12 Pixel Extended ROM.
