Every Samsung S2 owner that tried to use its video camera at night is frustrated with the frame rate drop it suffers. It`s an inexplicable mistake by Samsung, and one that cost them many clients. When recording a video in a dark space, the frame rates of the video would drop when the camera focused, making the video look like it was in slow motion, and with bad quality.
The solution to this problem made the videos become too dark and sometimes unwatchable.
No more. A XDA-developers forum user figured out how to solve this issue: lowering the ISO. If you wanna know how to do this follow the following link: http://forum.xda-developers.com/showthread.php?t=1888458
Have fun =)
