Following earlier reports revealing an unannounced buttonless HTC smartphone due to be launched by Verizon Wireless, images of a second unnamed Android phone have been published. This new smartphone appears to be more in tune with HTC’s current higher-end models, suggesting that it may launch as a flagship device. The device was spied on a commuter train in Taipei and details are extremely scarce. The smartphone runs Android, as evidenced by the four touch-sensitive buttons beneath the display and the visible on-screen menu bar, and it appears to have a front-facing camera for video chat. Beyond that, the phone is a mystery. Hit the jump for two more images of the unnamed handset.
