Taiwan-based smartphone maker HTC pleased their users as their One M8 handsets have started rolling out its software to the Android v4.4.3 KitKat upgrade with the Sense 6 UI.

Mo Versi, Vice President of HTC, announced via Twitter that the Android 4.4.3 OTA update will be received soon by HTC One M8’s users. Earlier last week, he said that the update will come with incorporated security fixes from Android 4.4.4.

However, this update will be applicable for the users of HTC One M8’s international variant. Those with the locked variants will be receiving it later on, although no schedule has been said from HTC.

It was reported that this Android 4.4.3 KitKat OTA upgrade would be 592.17 MB in size. HTC One M7’s OS has also been kept up to date with the same OS upgrade. HTC tweeted the Kernel source code last Tuesday, along with the One M8’s source code for Sprint wireless devices.

Nonetheless, this OS update would surely benefit the users of HTC One M8. However, when Versi was asked as to when One M7 will be receiving the Android 4.4.4 update, he replied, “M7 will go directly to L release for next update.”

This may likewise be concluded for the HTC One M8 and other variants of the device.

It was back in February when HTC rolled out an upgrade on Android 4.4 KitKat OS for its One M7, followed by the Sense 6 UI sized with 670MB in May.
