Some of Samsung's Galaxy S devices in the U.S. have been having problems with their GPSs, and while Sprint's Epic 4G seems to have avoided those issues, it's having problems of its own right now.  We received a tip from an Epic owner stating that he's had his uploads capped at 150 kbps on three separate Epics, and a forum thread over at Sprint's forums has similar reports from several other users.  The problem has persisted even after the recent DI07 update.  We reached out to Sprint about the issue and were given the following response:

"We have heard reports of users experiencing less-than-expected 3G upload speeds with their Samsung Epic 4G.  After extensive investigation, Sprint and Samsung have identified an enhancement that may improve upload speeds on the Epic. This fix will be made available in the next maintenance release.  It’s important to note that network speeds are impacted by many factors when using commercially-available speed test applications and test results may or may not be true indicator of the actual network performance."

There you go, Epic owners.  We only have to wait for the next maintenance update to come along and cure our slow upload woes.  Unfortunately, we have no idea when the fix will come but, considering the outcry from users on Sprint's forums, let's hope it's sooner rather than later.  While we wait for the update to come, maybe you should just try to stay near a WiFi hotspot if you're going to be uploading anything.

Thanks to Vince for the tip!
