[Q] Camera: set iso, shutter speed etc? - Touch Pro, Fuze General

Hi, as you all know fuze/TP cam is good when there is a lot of light but sucks with low light.
So:
- is there a way/app to manually modify ISO or shutter speed?
- is there a way to deactivare autofocus?
- is there a way set focus to infinite so it does not have to focus every time?
- is there an alternative apps for taking pictures?
Thank you

[Q] API for precisely modifying shutter speed, ISO, and aperture as exactly as I want

For the research purpose, I need to be able to control the shutter speed precisely without affecting or changing the ISO or the aperture. The shutter speed needs to vary from 10ms to 2000ms, with a step of 10ms. So that means there needs to be 200 different options for shutter speed, and so far the best apps for android phone just offer a few, and still they cannot keep the values of the aperture and the ISO the same in all images. I really wish that they can make the app in a way that I can plug in number for my shutter speed, ISO and aperture, and they have to maintain the same values no matter when or where I take a photo; for instance 1.27 seconds for exposure time, f/1.42 for aperture, 800 for ISO. I've been thinking about program my own app, but I have no idea how to start. I don't even know if it is possible to program an app that can really allow us to plug in numbers for the shutter speed, ISO, and aperture precisely in millisecond. Is there any idea?

Is there a way I can change the camera shutter speed?

I know there's no option for it in the default camera app, but is there any other way I can controll camera shutter speed on Galaxy S6?

Open Camera does it. Its labelled as exposure but it seems to control shutter speed, ie exposure length.

lag on front camera

did anyone noticed that`s the front camera with (no effect)is too laggy specially in low light?
if i change the effect like( vignette )the camera begain very smothly
is that`s a softwear of a hardware issue?
That's normal. In low light the shutter speed goes down to low values e.g. 1/15 to have the exposure right, which means that you'll see stutering (1/15 = 15 fps). With the effects enabled, the picture becomes darker. Technically, the issue is with the effects, not the normal mode.

Camera shutter speed problems.

For some reason the camera seems to heavily favour lower iso than high shutter speed. Such as having 1/33 shutter speed at iso 64. So it's useless for anything moving.

Camera slow focus and shutter speed.

do you guys find the camera abit slow on focusing and when we press shoot the shutter will also slow? im not able to take my 1 YO son's photo without blurry face. :crying:
Occasionally in dodgy lighting (especially indoors). I get the sharpening image message.
