with his 4/28 zip i have yet to experience any echo, on my end aswell as who ever it's connected to. is this only an issue with those of you manually patching things into 4/22s build?
as for me the only issues with 4/28 I've experienced are listed on the first page. which basically for me means everything is working. besides the light not shutting off after you press the power button occasionally.
I used his first public build. flashed back to stock firmware c. now on the 29th i flashed to 4/28 progress update. and i am pleased to say the least
p. s no problems with any resolution wallpaper or live wallpaper
oh yeah. I don't use programs for Facebook (so i cannot comment on those issues) . I've never used any 3rd party garbage widget or app for any social stuff i. e twitter Facebook etc, especially since I can just use the web browser to stop in from time to time
another oh yeah, the status bar does lock up occasionally, after you drag it down you do have to press the back button for it to scroll back up. but it doesnt glitch out or hang down half way like other status bar glitches
