Issues

A fair number of users report a "SLOG DUMP" error message appearing on the screen, after which the phone exhibited various issues such as the phone being unable to receive calls or freezing. In many cases, such problems can be corrected by rebooting the device or removing the battery. The phone also stops playing all audio at times, and the touchscreen may also stop responding. If a standard reboot or battery removal does not fix the problem, the phone can be started in "format mode" for a more complete reboot. Samsung released an ID1 update addressing many of the issues reported by users, but users report that the update actually made things worse, introducing things such as a dialing lag or all incoming calls going straight to voicemail.

Windows Mobile 6.5

Samsung has released an official upgrade to Windows Mobile 6.5 for the Epix, in June 2010. Users have had success installing unofficial Windows Mobile 6.5 on the Epix for the last year, although it currently has various issues such as artifacts appearing around the mouse pointer. The official release fixes most of the problems in the unofficial ROM, including the mouse pointer, GPS issues, speed, and battery life.
