It looks like the Sprint Samsung Epic 4G Touch and the LG Optimus S are having some minor issues. The Epic 4G Touch has an issue with the calendar app force closing when multiple events are dismissed. There is also an issue when using the 4G hotspot and you take a phone call, the 4G connection will be killed. Samsung is aware of both of these issues and are working on a fix. Hopefully it will be sooner rather than later, but at least they are not serious issues.
As to the LG Optimus S, a recent update went out which deleted the predictive text database for the Android keyboard. For now Sprint is recommending users to switch to the built-in Swype keyboard or another third party keyboard. It appears there are some other issues with this latest update so hopefully LG can resolve them soon. Let us know if you are having any other issues.
