I have had Samsung Captivate for a couple of weeks. And I have come across the following. 1. The Maps app (Google Maps) shows my location about a mile from where I really am. This despite syncing my location outside where GPS would be available. Surprised that the app does not communicate over wi-fi. Or may be there is another reason - a problem with the phone/OS. I doubt this is a problem with G Maps, since it worked just fine on my BB Bold 9000. 2. The phone display at times freezes for a few seconds when navigating across emails and other apps. 3. The POP/SMTP emails do not push as configured (every hour). Every time I go into Mail app, it goes in a circles to get the emails (and that is when I do not get communication error which is about 3 out of 5 times). 4. Tooks two weeks of pain to get CompanionLink to work to sync Outlook Contacts, Calendar and Notes. 5. There seem to be some hiccup in handover from wi-fi to cell network. I do not get good ATT signals, so wi-fi is crucial. But 2 out of 5 times, the apps do not work. This happens with various apps, and hence the reason to believe that it is a phone/OS problem. But could be wrong. 6. The battery does not even last for a day - and I mean waking hours. 7. Does not seem to b e a good way to find out how much memory is available, so at least once a day I have to either recycle the power or do a battery pull. 8. The web site www.woot.com (now owned by Amazon) invariably crashes the browser. Will add more as I come across. If anyone has any solutions to some of these problems, please do post here. Thanks much.
