According to LlabTooFeR, who is well in the loop about HTC related information, the One M8 will start receiving its Android 5.0 update within the next two weeks. He mentions that EU and WWE (Worldwide English) regions will be the first to get the update, but there’s still no word on when the American carrier variants of the handset will receive the coveted update.
This is pretty much everything he mentions in his tweet with no word on whether there will be any new additions to the Lollipop ROM. But earlier leaks have given us a good idea of what to expect from the Android 5.0 ROM for HTC flagships, so there are barely any surprises left. While we expect there to be some Material Design elements with the ROM, HTC will maintain its stock theme and make some improvements to the look and feel of the home screen.
We expect to get more word on this new ROM over the coming weeks.
