Just got my SGSII yesterday, immediatly flashed this ROM. Besides 1 thing everything is working fine That one thing is headphone detection, it wasn't working. (It's working partially now, more on that below).
I had similar problems with the HTC Desire once, where a reboot resolved my problem. Didn't help for the SGSII, so after a few tries I decided to use the 'toggle Headset 2' widget after a bit of googling. That enabled my headphone output, but there was no headphone icon at the top of the screen.
For some reason the detection seems to be working now after using the widget, so I don't have to use that anymore, but there still is no headphone icon when I plug in. Is this disabled in this rom / on the SGSII or is something wrong and if so does anyone have a suggestion?
I will probably try a hard-reset tonight, but if there are solutions which don't involve a hard reset I would definately prefer that
This seems to be a general Galaxy issue.. I have the same problem on my Tablet (10.1 thin) as my SGSII (both before this rom and after)
