As the newly released new version of Android system, Android 5.0 Lollipop not only adopts the new Material Design design, which optimizes the visual effect of the interface, but also adds the animation effect with higher color contrast. At the same time, in addition to more excellent multitasking functions, support for 64 bit ART virtual machines and security improvement, the Android Lollipop system also brings new functions such as new battery mode, multi account login, visitor mode, and unlocking through Bluetooth devices.

Both HTC One M7 and HTC One M8 will be upgraded within 90 days.

HTC One Mini and HTC One Mini 2 will also be upgraded, but the specific time has yet to be determined.
