Review: Samsung Galaxy Prevail
Bluetooth
The Prevail supports mono and stereo Bluetooth headsets. I had no trouble pairing with either. Sound quality through mono headphones was not all that great. Quality through stereo headphones was terrible. I was also able to pair it with my computers and other handsets for sharing images, etc.
Clock
The Prevail offers the standard Android clock on the lock screen, which is visible when the device is first woken from sleep. It is a nice, large digital read out that's easily visible everywhere except under direct sunlight.
GPS
The Prevail offers two options for directions: Google Maps and TeleNav. Both are free. I enjoy Google Maps and think it does a great job of providing directions. TeleNav is a solid alternative, though, and Sprint doesn't charge for its use. Both will get you from here to there with no problems. The TeleNav app also offers voice commands, though they only worked about 50% of the time.
