Since i was i previous owner of a Galaxy s iii i have realized that the flashlight is around half as bright as the SIII, i was wondering if it was possible to turn up the brightness a little?
Or if it would cause any damage

The flash does not need to be as bright as the camera sensor is more sensitive.
It is really there for camera.
So since the s4 camera does not need as bright a flash as the s3... the light wont be as bright as you want.
Turning it up could cause a damage however but you would need a custom kernel to achieve that.

When using the flash while taking pics on the S4 the flash goes 100% bright like the SIII but only for a second, if the SIII can handle 100% brightness why cant the S4?

The LED does go 100% bright if needed...
but the LED itself on S4 is set up to be more power efficient.
Remember the sensor on the S4 is more sensitive and performs better than the sensor for the S3 ...
S4 camera DOES NOT NEED as powerful a flash / video light from the LED as the S3
so by default the S4 can run the LED at a slightly lower intensity because the Camera sensor by itself captures more light than the S3 does.

Its not that the S4 cannot go as bright as the S3... but by default it DOES NOT NEED TO.
and almost any app you use on an un-rooted device is going to use those default settings.

I remember an app way back on my HTC Desire that had an option to enable experimental Max brightness, it was a flashlight app in
cyanogenmod. I dont suppose that something like that could work on the S4?

You supposed wrong.
As long as a custom kernel properly exposes the relevant LED variables an app can be constructed to utilize them (if it doesnt exist already)
Running these camera LEDs far outside nominal design limits for long periods of time may cause damage.

Major find people.
The proximity sensor that we have is in fact light sensor / proximity sensor combo.
Its name is GP2A
Samsung disabled light sensor (in kernel) probably by either modifying drivers to exclude the light part or by removing driver completly
I managed to find kernel driver for this sensor (from some unknown device), which link you can find below:
http://o2droid.phj.hu/trac/browser/kern_oII/drivers/sensor/optical/gp2a.c?rev=2
So kernel devs, rock on!!!
maclaw and all devs should know this.
hope it works this kernel driver :fingers-crossed:, the s3 mini should be factory the auto brightness
Great there is still hope for light sensor !! Just inform devs

Haha I can't believe it, that link refers to a Omnia2Droid page! It's an old team who ported Android 2.1/2.2 to the Omnia 2/Pro (WinMo 6.x devices) years ago, I had one of those with that buggy droid installed
Edit for developers - that driver comes from a Samsung I5700 Galaxy Spica (Android 2.1),a device launched in 2009
Edit2 - found this driver from google https://android.googlesource.com/ke...2929fc99325ee399fd9/drivers/input/misc/gp2a.c
and this one,the most recent one https://bitbucket.org/sarcastillo/redpillkernel/src/990eb0053acb/drivers/input/misc/gp2a.h
Woooo, hope at last!

1. Don't get so excited. Even if it's light sensor also, other hardware parts can still prevent us from using light sensor function.
2. Galaxy Spica doesn't have any proximity/light sensor - I have a Spica
3. Drivers which you attached are completely useless on Jellybean & 3.x kernels.
Sure, getting working something completely broken by Samsung is most important for me at this moment...
It isn't so easy to get light sensor working, I'm not sure if it is possible.
But we will look into it and check it out.

I think it's very hard. If I not wrong, Samsung's AMOLED panel is in one piece with the capacitive buttons and the sensors and the front speaker except camera. so I think it's hard to make a hole on it
Wait...s3 has 2 holes and has light sensor. WTF?!!!

I thing there is no chance to get it working :/ I had dismantle my s iii mini and looked on the sensor and there is only proximity. I am refer to pdf from New Macław's post. If you open it you will see on first page two types os senzors.I thing tahet we have the "Upper left" type and there is no ambient part :/

It says the proximity sensor is combined with light sensor, part number cm3623. Galaxy s4 mini has only 3 holes on front panel, 2 for proximity and 1 for front camera. But it HAS light sensor and auto brightness. My question is: Is it possible that it uses the IR sensor part of the proximity sensor for light sensor? I think it is.

There is a lightsensor too

and on call screen

there is light sensor settings to the test
Anybody got this? In low brightness some darker elements(specially gray) start become a little purplish
Also the colors seem less saturated in the default screen mode than the s3(also in standard) i thought i would be the opposite, is my screen defective or is this normal
I tried google but all i get are galaxy nexus results(purple tint)

Welcome to S4. Every galaxy S4 has this. Please refer to other threads on how to get rid of this smearing through software.
Sent from my GT-I9500 using xda premium
The OP doesn't mention smearing.
This is a different issue to the smearing problem.
When the brightness is on low greys become purple. I have had 4 different S4s (all had to be replaced due to screen issues) and every single one had this problem on low brightness.
IMO there is no such thing as a perfect S4 screen!
I have finally settled on my 4th replacement and this one is still not great but I'm sick of returning them.
I have a pink tint at the top of this screen and also all the sensors, LED and front camera are misaligned in the casing, All over to the left.
Samsung have REALLY failed on the Quality Control of this device.
So it seems universal, well i will have to turn off auto brightness and use brightness at 30%
Any of u guys came from the s3? Do the s4 colors seem a little less saturated to u guys? I have them both side by side and it seems so

Yes. I had s3 before and the less saturation on S4 is intentional by Samsung. According to some detailed comparison, the colors of s4 are more accurate. It seems odd at first because our eyes are used to the oversatured screen of s3.

I use anti shake function cos the picutures is more sharpness...center metering...and i still testing my S4 camera. Im not satisfied with the sharpness of the pictures, the S3 have better camera i think (for now)
Another question to ask is are you using an i9500 or i9505? I believe they use different sensor?
I have i9505 and camera in normal lighting is awesome. A little grainy in low light but not as bad as the camera in my HTC legend.
Anti-shake on here, not sure if there is any significant advantage.

i have the att version which is quad core like yours so i think its the same sensor.
Compared to other phones, does this LED light (using for flashlight) perform a lot less than other phones or is it just mine? Compared to my phone in the past, this LED is VERY dim. My S3 had an overwhelming bright light.
I have not really compared mine with any phone, I will compare the Z1 with SGS4 when I get home from work and let you know
Light out put is less than my N4

It's pretty weak i must admit.
Compared to my Note 2 and iPhone 5s, it's very weak.
You don't want it strong like iPhone or the likes it kinda kills the photo and makes it to cool that is why on a dslr the flash is usually taken about 1 second before the shot so it dims a bit before the photo is shot so it adds more warmth rather then making the photo over cool

Pretty much in agreement that the light is week. Okay. I just wanted to make sure it wasn't just mine.
Yes, it's very weak. With my Galaxy S3 it would perform better than a torch when it was dark outside. With my Xperia Z1 its crap as a torch. I'm not to bummed about it. Hell I hardly ever use Flash anyways.

You should note that the Led is dim if you use it as a torch with a widget or program. But in camera mode when it's used as a flash it is pulsed much brighter! Test it for yourself.
@TheCraig: Yep, same here. I guess the Led of my Play could be used to make fire.

I am not good at photography...
So if anyone could help me out with the setting or is it the camera?
U can't see the photos for yourself and if it's good for the note camera please tell me?

Note 3 camera is different from Note 2.
It has so many mode, and a lot auto settings.
especially when you are using auto mode, it will try to adjust the picture you shoot for the best result. So if you use this one under low light conditions, it will go into processing. When it is still processing, and you hand move/shake a bit, it will turn into "blur".
Note 3 camera is good in processing under good lighting conditions.
Under low light, use blitz will be better, but color result will be different compare without blitz.
This is so far I know about this camera, I just use a while only, and most of the times I'm still using my Note 2. perhaps others can tell you better.
