That doesn't look right. Have you zoomed in when you took those screenshots? Could you upload the picture itself instead of screenshots?

The amount of noise in T2 Ultra is like that.

If you want here's one of my picture, object distance is 2 meters take the picture with 13MP resolution

this one taken while zoomed at hal amount

the noise and blur just annoying

and here the full picture if you wanted

my phone model is D5322, processor Qualcomm MSM8228, android ver: 4.4.2, kernel: 3.4.0+ BuildUser@BuildHost #1 Thu Jun 19:14:10:46 2014

Build Number: 19.1.C.0.116

From Indonesia.

By the way already tried to fix the phone, and factory reset and such thing too.

it happen after the last update, been long waiting for fix

It seems there was poor light when you took this picture? You have used no flash and the phone has used a higher ISO (which gives some noise) and longer exposure time which may make it less sharp as you need to hold the phone very still.

If i take a picture with my T2 Ultra indoors it uses half the ISO and a third of the exposure time compared to your picture.
Try turning on the flash or take a picture where there's better light and see if there's any difference.

okay., tried a bit your suggestion

I try this one in pretty bright room with ISO 200 and +1/4 exposure

and tried this one with same exposure but auto ISO

when zoomed the amount of noise is having big different

and also I realized that when I put the setting to auto or not the capture speed is a bit slower compared to other phone, is there some mistake I made

and here also few picture I take again the distance at least 1 meter

Spoiler

ISO 200, Exposure 1/4

I don't know which is at wrong but bluntly said when zoomed closely and compared to Competitors phone using 8MP camera T2 Ultra lose, both is set at auto setting.

Maybe you can give some explanation cause usually 5MP difference is big.

is it settings related or software related ?

if settings related maybe you can give suggestion, and if it's software related wil there be an update in future ?

Thanks for testing.

Checking the details of the pictures the first one was taken with ISO-150, the second with ISO-800 and the third was actually taken with ISO-950 and not ISO-200.

I'm afraid it's hard to say from here what the best value should be for the circumstances when you took them but when i test it here my unit rarely goes above ISO-400 in normal indoor light. It seems when you set ISO to auto the camera uses a higher ISO but shorter exposure time. It's better for moving objects but will give some noise.
I will forward this as feedback internally to see if any improvements can be made but if you want to avoid noise when taking a picture in poor light you can manually select a low ISO but it's more important to keep the phone still as it uses a longer exposure.

Okay., I'll keep that in mind about the ISO setting

Thanks for the answer and suggestion

oh., and one last thing for the front camera it seems that we can't set anything like ISO in front camera as usual, but after the update the front camera got lot of noise like black pixel thing, and when I took picture using the front camera the result appear darker than what the camera shown.

why's it like that sir ?

and lastly it appear the at kitkat the battery life is draining quicker compared jellybean as I experienced

also will there be any update or patch in future ?

like some rumour maybe

Anyway thanks alot for replying

really appreciate that

You can't set ISO for the front camera i'm afraid.
The viewfinder in a digital camera usually uses other settings then for the capture itself to improve the performance of the tracking when using the viewfinder. This is why the picture you take may not have the same brighness and colour as it had in the viewfinder. When you take the picture the camera will use settings that are better suited for a capture than for tracking. The viewfinder usually has more noise in poor light.

I don't have any information if there will be more changes made to the camera.

Okay then., i'm okay with not being able to set ISO at front camera.

but the front camera used to be better than now before the update.

Thanks for the explanation
