It seemed to me we should have a thread covering Android 2.2 Froyo changes we find OTHER THAN than the major changes officially listed by Samsung and in the updates threads. I suggest bugs be listed in the bugs thread, NOT here (unless incidental to describing a change).
Here are my contributions...
1) Camcorder saves as .mp4 instead of .3gp
2) Camera/Camcorder have thumbnail of last photo/video as the button to the viewer
3) Browser favorites/history button now next to URL box instead of browser options.
4) Call log now includes both calls and text messages together.
5) Ability to uninstall from Applications menu (Settings / Edit)
6) Battery fully charged icon now in notification area. Unplug/Plug to reset. (I don't like it myself.) Screen saver covers the old fully charged pop up (I DO like that.)
7) When you go to add a shortcut or widget via the "Add to Home Screen" menu, the Widgets and Shortcuts lists are no longer split into sub-groups. You don't have to remember which list has the item you want.
8) GPS accuracy used to always just say 98 feet... period. The interesting thing I want to report is that it now varies quite a bit in a short time (which seems more realistic). It looks to me like as well as the accuracy going up, the reported accuracy is sampled at a higher rate or is no longer rounded somewhere? In any case... NICE! (BTW, so far I have seen it as low as 8 feet.)
9) Contacts / Groups Tab: Instead of picking a group, all groups are listed in sections with group headers.
10) The app store layout changed with the 2nd Froyo release on 3/24.
