This smartphone has next to 4G speeds, a large 4.3-inch display, fast 1GHz Snapdragon processor, plenty of storage space, and the ability to share its fast connection with up to eight Wi-Fi enabled devices through the Mobile Hotspot feature.
keyboard:
The onscreen keyboard that comes with the Thunderbolt does the job, but the reviewers still prefer some of the third-party keyboards that are available such as SWYPE or SwiftKey.
Camera and Video:
On the back of the phone, there's an 8 megapixel camera and dual LED flash. This rear camera is capable of HD (720p) video recording.
Battery Life:
For this test, the Thunderbolt managed to last 3 hours and 36 minutes before it died.
