The HTC One max is the large version of the HTC One and completes the 2013 One series from HTC. It was introduced in mid-October, two weeks before the start of sales. The One max really is the max with its nearly 6-inch display, the biggest HTC smartphone yet. It is also the first HTC device with a biometric fingerprint sensor. The user interface Sense 5.5 brings improvements to HTC's proprietary Blinkfeed and the camera software. The internal memory of 16 GB can be expanded via microSD card. After the sudden end of a two year collaboration between HTC and Beats by Dre, the One max arrived without Beats Audio sound enhancement.
