    it looks, feels great and works good…has a bit lag at home screens..wifi, gps working fine…the main and only issue I found is, and probably because this is a version from a bigger phone, the icons and lettering are to small..even when increasing the the font size at maximum on the display settings it is very hard to read and get the right readability….the 6×5 icons incons display could be decreased to a 5×4 one and it would solve the issue i think…Get it done and it will be my #1 rom!!! Thanks for your effort robin.raven and keep on rollong the great stuff!!! Regards!

    Very good firmware. Looks a bit too small because of the high resolution. If this is correct, there would be just super!!

    Isn't it possible to change the  resolution with the app "Resolution changer" into

    720×1280-320 Dpi?

    I haven't installed this rom yet so I didn't try.
