It is big, it is shiny, and it is powerful. The HTC U Ultra is a high-end Android phone built to impress at first sight with its stylish design. The back and front are made of single glass sheets, and a metal frame holds the exterior together. Another key selling point is the built-in HTC Sense Companion - an AI assistant developed to provide tips, suggestions, and alerts proactively. That is paired with four high-quality always-on microphones, allowing the HTC U Ultra to respond to voice commands. To serve you better, the phone sports a secondary display above the main one - Companion messages are shown there without interrupting your workflow. One downside: there's no headphone jack on the Ultra. Instead, it employs USB-C earphones that can adapt to the user's ear structure using ultrasonic technology. For those demanding the very best, a limited edition HTC U Ultra will also offer sapphire glass protection and 128 GB of native storage.
