A commenter at the SE blog, has just posted about an upcoming firmware release for the K850. The new firmware will called R1DA038 and it looks like there will be some major improvements on the camera side. The current camera version is 2.9, while the new firmware’s camera version will be v. 3.4. Video call camera is the same. I hope this news is true since the current R1CA037 doesn’t fix the problems at all…
Update: The new firmware finally available at SEUS, but only for selected country, and only work on unbranded phone.
Here the firmware highlight:
