Mobile photographers will appreciate the 20-megapixel rear-facing camera the highest to date in the One family. Plus film makers aren't neglected either with the inclusion of 4K30 1080p60 and 720p120 video recording. Additionally the front camera has been bumped up to an UltraPixel for this generation of HTC's flagship. The phone features 32GB built-in memory which can be further expanded using a separately available micro - SDXC card up to 128GB. For connecting to a computer and charging there is a micro-USB port with MHL support and there is a 3.5mm headphone/mic input combo jack. Bluetooth 4.1 is provided for headsets linking to a computer or tablet or connecting with other close-range devices while consuming substantially less power than Wi-Fi would require.
