If the smartphone HTC One M8 started receiving the update Android Lollipop, going directly to version 5.0.1, only the Google Edition version with the stock Android system, in other words without overlay, is concerned for the moment. This one proposed by the manufacturer with its own graphical interface will arrive a little later.
In the meantime, here are two short videos that will give you an idea of the Android Lollipop environment revised and corrected by HTC, with the Sense in-house overlay. We discover some functions and the simplified mode.
The Android 5.0 Lollipop update comes with a reminder of a new design, a new notification system, better data security thanks to Factory Reset Protection / Kill Switch devices and better autonomy thanks to contributions from the Volta Project which gives hope for up to 2 hours of additional autonomy. Patch 5.0.1 fixes some residual bugs.
