4GB M2 for K810i

[senter]

4GB work fine on my K800@K810 !
Only Video player is slow (with ~ 1 GB video = 60 - 70 video clips) and start for 6 - 7 s.

Apart from videos does it lag anywhere else. I don't use my phone as a video player. Its only use will be to say hi hello, music player and camera!??

No lag's, only phone starts slow (if is turned off before).
In anywhere: running quickly without thinking, pictures save quickly (~3 s. without date & time, ~7 s. with date & time on picture), simply no difference like with 1 GB card.
