Review: HTC Sensation 4G
Apps
The Sensation 4G can access all of the apps in the Android Market and more. Support for Android is not lacking. If you want apps, they are out there. The Sensation 4G also has the HTC Hub on board, which is a small app store that lets users peruse HTC-developed applications. The one thing that stinks is that HTC forces you to sign up for an HTC Sense account in order to access and use the HTC Hub. While I understand HTC's desire to make its customers invest themselves in its services, users of HTC's Windows Phone 7 devices, for example, don't have to go through the hassle of signing up for an HTC account to use the HTC Hub.
For the vain, there is a Mirror application on the Sensation 4G. It uses the front-facing video camera to capture your image so you can adjust your makeup, comb your hair, or just gaze into your own eyes.
Bluetooth
The Sensation 4G can connect with mono and stereo headsets with no problems. I didn't encounter any issues when pairing different devices, and sound quality through both mono and stereo headsets was about as noisy as standard phone calls were. The Sensation 4G can also be used to push pictures (and other files) between devices, such as PCs or other phones. This feature also worked just fine.
Clock
HTC has knocked the clock out of the park with Sense 3.0. Awesome, awesome, awesome. The lock screen has a completely customizable clock that is large, bright, and readable in most circumstances. There is a full clock application in the main menu that lets you choose between a dozen or so different clock faces and styles. There are enough in there to suit most tastes. Some of the clock faces are really, really cool.
Once unlocked, the Sensation 4G has the standard HTC digital clock plus weather report on the home screen. Good stuff.
GPS
Both TeleNav and Google Maps are installed on the Sensation 4G out of the box. Both offer voice-guided turn-by-turn directions between points, and can re-route you if you get lost. Google Maps 5 is particularly impressive because it now offers offline use (in case you roam out of network coverage) as well as 3D maps for a limited number of cities. The TeleNav software is very good, but it costs $10 per month to use.
Mobile Hotspot
The Sensation 4G includes Wi-Fi mobile hotspot, allowing up to five other Wi-Fi devices to connect to the internet via T-Mobile's HSPA+ network. The software is fairly intuitive and I had no trouble setting up a hotspot and connecting several devices.
