After the release of the Samsung Epic Touch 4G, the Sprint version of the Samsung Galaxy S II, a fair amount of Sprint customers reported they were having issues with signal loss on the flagship device.
Sprint has now started rolling out update D710.0.5S.EK02 which among other things addresses and corrects the signal loss issue.
Another minor flaw with the Epic Touch 4G was that if you were using 4G mobile hot spot and a call came in the phone wouldn’t shut off the hotspot which resulted in a quicker battery drain. This issue has also been fixed with the update.
There may be some other minor bug fixes also in this update. Several customers have reported seeing the update available on their handsets, if you don’t see it go to settings, about phone and update and it should be there.
