The ICS beta7 is super. I am following this thread almost from last 4 months. I think the basic feature to be fixed in this ICS release is Camera!
I think if possible please fix the camera issue with bit priority. Once the camera is working then people might start using the beta release. Once it is in use then you will get any further bugs, if exists.
Having phone with 5 megapixel camera without working, i guess people hardly try to use this release.
I know its a beta release and it is the period where most of the issues need to be fixed. If you think I am right then kindly try to get camera working, then you will see more and more people start using and possibly get all hidden issues, if any.
