HTC appears to have started rolling out over-the-air (OTA) the
Android 4.4.4 KitKat update for its One (M8) users in India. The update
is reported to bundled along with the HTC Eye Experience suite, just
the like the update was rolled out last month in Europe.
The
over-the-air update for HTC One (M8) is said to be sized at
288.45MB, as per a user report (via
AndroidOS). Users can keep a check on availability of the OTA update by
navigating to Settings>About Phone>Software Update on their
phone.
The Android 4.4.4 KitKat update for the HTC One (M8)
includes HTC Eye Experience, the new mobile
imaging software which was released on the HTC Desire Eye in October. Beyond
describing the new features HTC Eye Experience will bring, HTC has not
detailed the new Sense UI features and other changes that come along
with the update in the changelog (seen in the user's screenshot).

Besides
the HTC One (M8), the firm will bring the same software to HTC One
(M7), HTC One (E8), HTC One
mini, HTC One mini 2, HTC One Max, HTC Desire 816, HTC Desire 820 and HTC Butterfly 2.
Some of the
notable features of the HTC Eye Experience include a new Split Capture
function that allows simultaneous images or videos taken from the front
and back cameras to be combined into one split-screen image or video;
Crop-Me-In, which allows a user to crop an image or video taken with the
front-facing camera and superimpose it within a scene captured by the
main camera; Voice Selfie lets users click images from the front camera
by just using voice commands; Face Fusion technology, which allows users
to merge two faces into an image, and Live Makeup, an option to
beautify selfies.
HTC also confirmed that four of its smartphones
will be receiving
an update to Android 5.0 Lollipop. The smartphones which will be
receiving the update are HTC One (M7); the HTC One (M8); the HTC One
mini, and the HTC One mini 2.
