I know that it changes based on conditions...

In daylight, most likely it will shoot at ISO10 with 1/640s
In deepest dark, most likely will shoot at ISO8000 with 1/4s

The bug is, when I enabled Night mode in T700 standard, and shot my room (halogen lamp powered)... There's much noise on my photo, and it looks that it is ISO 400.

But in EXIF (using photoshop), it ALWAYSsays ISO-10, which is impossible, since the noise looks like ISO 400. I can tell the difference of ISO 10 and ISO 400 by looking at the amount of noise.

I change the lighting condition (more darkness), and it still says ISO10!

So I think there's a bug in JPEG writing algorithm...

For these sensors is a necessary a good condition of luminosity, this sensors work well with high ligth and this models mobile phone don´t have xenon flash or led flash for to conditions of low light.
About ISO in this sensor is relative and useless because the sensor don´t respond with the variations of ISO unfortunately.
Example: ISO10 ISO80 ISO100 ISO200 ISO400 ISO800 ISO8000...ISO(n)
All these ISO have the same effect about the pics.
Try to change the ISO and see the results or if the pics change some thing.
But where are the pics??

I will upload the pic. Maybe tomorrow because I have slow upload speed internet connection. Sorry for waiting.

Thanks For Your Attention

my W890i.
hey Brazuka, what did u mean " Try to change the ISO and see the results" ? on my W890i i just can adjust the EV setting ( left and right key, landscape mode). How can I change the ISO on the phone? Or editting the file camdrive0.dat ?
Open it on the text editor, i saw you had something like "Modders and Users if necessary change the values for Video Recording FPS", but how ?
The images are still more noisy and blurer than the original camdrive, except for better color. It also losts detail. I wish you could complete it soon.

Yes, inside of camdriver0.dat... open camdriver0.dat and change edit if necessary function FPS video recording

Modders and Users if necessary change the values for Video Recording FPS
if don´t know, not touch anything below

//----------------------for 15fps to 23fps
//Photos:stable
//Video:stable
//cam_vf_clock_freq=9,4E20; // Clock #9 on, frequency 20MHz for video recording 15fps to 23fps
//cam_ss_clock_freq=9,32C8; // Clock #9 on, frequency 13MHz for video recording 15fps to 23fps
//----------------------for 15fps to 26fps
//Photos:stable
//Video:stable
//cam_vf_clock_freq=9,55F0; // Clock #9 on, frequency 22MHz stable fix for video recording 15fps to 26fps
//cam_ss_clock_freq=9,32C8; // Clock #9 on, frequency 13MHz stable fix for video recording 15fps to 26fps
//----------------------for 25fps to 30fps
//Photos:unstable
//Video:stable
//cam_vf_clock_freq=9,6590; // Clock #9 on, frequency 26MHz for video recording 25fps to 30fps
//cam_ss_clock_freq=9,32C8; // Clock #9 on, frequency 13MHz for video recording 25fps to 30fps
//----------------------Settings for Video FPS Only Video!!!

so just remove "//" in
"//cam_vf_clock_freq=9,55F0;
//cam_ss_clock_freq=9,32C8;" right ?
and the ISO ? how to edit ? I 've got over-exposure when I shoot outdoor,although I reduced the EV.

yes remove " // "

find the property CALC_ISO_SPEED=

settings ISO here:

// Register 0x302A | ISO Speeds
//-----------------+------------------------
// R0 // 20 // 32 // 64 // 127
// Register 0x302A | ISO Speeds
//-----------------+------------------------
// R0 // 14 // 20 // 32 // 64 // 127

can I paste the part
"cam_vf_clock_freq=9,55F0;
cam_ss_clock_freq=9,32C8;"
into the original camdrive0.dat for increasing only the FPS of video ? Does it damage my camera sensor ?

Hey brazuka! Haven't seen you over there in a while.

Anyways, great cam drivers. However I have a quesiton. For the G705, which cam driver would you recommend for good picture taking and good videos? I need the videos to be taken at a good resolution with at least 20FPS, preferably the higher the better. I noticed that it says

Modders and Users if necessary change the values for Video Recording FPS
if don´t know, not touch anything below

so I didn't touch anything in the camdriver.
