OK, feedback coming...
First of all - install is quick and after a few random reboots the build stabilizes. It's a bit laggy and slow but this is because of the lack of HW acceleration (maybe?
). I tried a few phone calls and everything is perfect - I heard the other side as well as being well heard by the person with whom I've been spoken to.
Music is also OK - ICS found every single MP3 on my SD card and played all of them without any problems. Sound is loud and clear, no poppings, cracking or whatsoever.
Then came the disappointments.
The Facebook account: it did NOT synchronize with the phone book contacts. When I pressed 'Add FB account' the phone just threw me in the main menu. Tens of attempts... same result.
The phone book: where is the option "Show only contacts with phone numbers"?
Adding a shortcut or widget to home screen is a bit laggy - again HW acceleration lack?
So far so good
If I recall something else, will provide additional info. Bottomline: the build is _very_ good for beta and needs just a few stitches to become nice and stable
