Good morning, I am trying to help a friend install Exchange on his Galaxy S3 from Verizon. We are using the device right out of the box, no additional APPS. We have checked about / settings and the S3 is up to date. After adding the exchange account everything seems to function normally. HOWEVER after a little use the SYNC seems to fall off all while continuously trying to pull data. On our first S3 it actually overheated and my colleague was mailed another phone. We are having the same result with the replacement. We have tried to removing and re-adding the account and it appears to function normally for a short time before its back to syncing non stop. My colleague says its always spinning/loading even if there is no mail in the box. I have this exchange account functioning normally in OWA, Outlook, and even on 2 other prehistoric mobile devices. We are talking about a battery life of maybe an HR. I have found other folks with similar issues on JB but no fixes seem to be available. In fact many people are being directed to download and in some cases buy 3rd party APPS to handle exchange. The prior sounds crazy to me the device should handle this out of the box. I have only a little experience with this device and am curious how something like this works. Does GOOGLE provide 100% of the APP I am trying to use OR is Samsung licensing this from Google and adding their own code potentially specific for this device or carrier? Here are a few threads I found with other JB users having similar issues. http://code.google.com/p/android/issues/detail?id=37437 http://code.google.com/p/android/issues/detail?id=39728 If anyone has any ideas I would love to hear them, thanks in advance for your help.
