Many of the HTC One M8 users are waiting on fire for the New Sense 7.0 UI to hit their devices. Today, we have some good news for HTC users worldwide, HTC ROM developer @LlabTooFeR (trusted for HTC news) just tweeted some that Sense 7.0 UI will come with Android 5.1 Lollipop Update to the HTC One M8, One M8s, Desire Eye, Butterfly 2 and some other devices.
Non of the current devices will get Android 5.0.2 + Sense 7.0 (except M9)…Sense 7.0 become available with Android 5.1 only on some models.— LlabTooFeR (@LlabTooFeR) April 10, 2015
According to the source, the Android 5.0.2 update for HTC won’t pack the Sense 7.0 UI like what’s on the HTC One M9 currently. This means that current M8 users will have to wait a while for 5.1 Lollipop update to enjoy the New Sense 7.0 UI.

For sure Sense 7.0 will be available as update for M8, M8s, Desire EYE, Butterfly 2 and some other devices…— LlabTooFeR (@LlabTooFeR) April 10, 2015
As for the HTC One M7, it’s not clear yet if it will get updated to Sense 7.0 UI or not. The 2 years old flagship already received the 5.0.1 Lollipop update with Sense 6.0 UI earlier this year. Hopefully, HTC won’t forget its loyal “One” users.
