Review: Samsung Conquer 4G
The Conquer 4G 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.
The Conquer 4G offers the standard Android clock on the lock screen, which is visible when the device is first woken from sleep. It’s a nice, large digital read-out that's easily visible everywhere except under direct sunlight. It can't be customized, though.
The Conquer 4G only includes Google Maps. Sprint's TeleNav-based navigation service is lost. Google Maps and its Navigation and Places features make for a powerful set of tools when it comes to routing directions and discovering nearby points of interest. The trifecta of these applications means there's no excuse to get lost nor to find a great place for dinner. The Conquer 4G's GPS radio performed very well in most circumstances, and was able to pinpoint my location to within 15-25 feet most of the time.
Sprint Mobile Wallet
Sprint's upcoming Mobile Wallet service will use near-field communications technology mated to customer credit card accounts to enable tap-and-go mobile payments. The software to control it is installed on the Conquer 4G, but I was unable to use it to create an account. The service is currently being trialled in a few markets with a few retailers. Sprint will be expanding its availability over time.
