The HTC Evo 4G LTE is an Android smartphone developed by HTC Corporation to be released exclusively by Sprint. A successor to the previous HTC Evo 4G and 3D models, the Evo 4G LTE supports Sprint's LTE cellular network and its current-generation EV-DO network. The Evo 4G LTE shares features with its GSM counterpart, the HTC One X—such as the same dual-core 1.5 GHz processor used by the One X's LTE variant, a 4.7-inch screen, and Android 4.1 with HTC's Sense 4.0 interface. The Evo 4G LTE was also the first phone built with an all aluminum frame, leaving only a small plastic piece to allow the Sim and micro sd cards to be installed.

The HTC Evo 3D is a 3D-enabled Android smartphone developed by HTC, released exclusively in the United States through Sprint, and was re-released as a pre-paid smartphone by Virgin Mobile in May 2012 as the HTC Evo V 4G. A variation of Sprint's flagship HTC Evo 4G, the device is distinguished by its pair of 5 MP rear cameras, which made the Evo 3D the first cell phone to do so, which can be used to take photos or video in stereographic 3D, which can be viewed on its autostereoscopic display without the need for 3D glasses. Several GSM variants are also available in Canada, Europe and Asia.
