Review: Samsung Replenish
Bluetooth
The Replenish supports mono and stereo Bluetooth headsets. I had no trouble pairing with either. Sound quality through mono headphones was very good, on par with the standard voice calls. Quality through stereo headphones was also good. It also connects with computers and/or other phones for pushing files around.
Clock
The Replenish 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. It can't be customized, though.
GPS
The Replenish 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, and they worked well on the Replenish.
