we’ve had various readers come to us while experiencing sync issues with gmail on their droid phone. they apparently have been forced to manually sync rather than use the phone’s awesome auto-sync feature. our first look was obviously to make sure they had “background data” and “auto-sync” checked in accounts and sync settings which they had. and then also made sure that if they clicked on the particular gmail account in question, that the “sync gmail” box was checked which it was.
and then we discovered this handy little trick…
Go to menu -> Settings -> Applications -> Manage Applications.
Then click menu -> Filter -> All.
Scroll down until you see the Gmail and Gmail Storage. Click both of these and select clear data.
The phone will then resync with Gmail and all should be well.
let me know if you are still having gmail sync issues after this tip, but this should do the trick!
