The CyanogenMod 7 for Milestone A853 RC13 Final version is going to be upload by Nadlabak this evening, he finally got the DSI-fix module working better after serval DSI-fix test versions, many thanks to him, again, he is the man who let many people to see there is still a hope with the Milestone A853.
the base Android system version of CyanogenMod 7 for Milestone A853 RC13 Final is Android 2.3.5.
In this final RC13 update, we are getting stable DSI-fix, the solution is return to use the native kernel function, and fix the suspend problem, as the solution was changed, I was wondering if the display performance will still be improved, I tested the latest DSI-fix module, so far so good, no reboot , no screen freeze, the Gallery seems working better than before.
Another improvement is coming with the official CM source, the LED notification color is more closed to the natural color, but this is depended on the hardware of LED light.
