Issue 1 Time and date on calendar. If I have an event from PC calendar synced to phone (work shift 7a monday through 7a Tuesday on PC) it will show up as all day event on both days, and will not allow me to edit the date. and the time will be 4 hours off if I try and edit it. If I set the wheels to 0700 the time entered on the calendar will be 0300.
Issue 2 Battery life is a little worse...Mostly I had an issue witht he camera..if i use it at all it will show up as 92% in the battery usage area. If I restart the phone it seems to be ok unless I use the camera again. It does not show up in the running tasks under the applications menu. So I dont know.
The 50% without service bug i have..but airplane mode fixes that.
dialer seems a little laggy...but it gets all the inputs..only an issue if I get impatient...if i click the name to call it and just put it up to my ear..i can hear it ringing before the screen even shows it started calling...so physically the dialer isnt lagging just the UI for it is....
However, even with all of that..the positives of 2.1 greatly outweigh the negatives of 1.5. This is the first leak i flashed so i went from 1.5 to 2.1v3. I love the power bar widget, I am using helix with 7 screens and 14 widgets running. I like widgets over programs lol.
