HTC's One M8 flagships will not be receiving the Android 5.1.1 Lollipop update. Instead, the Taiwanese tech giant is heavily speculated to directly roll out the Android M upgrade later this year for both the handsets.

When a new Android device is launched, firmware updates are only available for 18 months after its launch. Hence, HTC One M8 owners were contemplating that their handsets will not be receiving the Android M upgrade.

However, Mo Versi, vice president for product management at HTC, has confirmed through a tweet that HTC One M8 will receive Android M upgrade, Phone Arena reported. In March, all the major U.S. carriers (except AT&T) released the Android 5.0 Lollipop update. AT&T rolled out the Android 5.0.2 Lollipop update.

HTC has not revealed any plans for rolling out the Android 5.1 or the Android 5.1.1 Lollipop update for the HTC One M8 handsets in the U.S. In the U.K., the company has not announced anything on rolling out Android 5.1 Lollipop for HTC One M8. Hence, rumors are claiming that the Android M will be directly brought to the device across the globe, Venture Capital Post reported.

According to Droid Report, the Android M update will fix two major problems for HTC One M8 owners, unstable Bluetooth connectivity and poor battery performance. The Doze feature of the Android M can delete all the previously used Bluetooth connections to resolve the Bluetooth issue and also kill all the background processes to extend the battery life.

The Android M update also is supposed to fix all the other bugs that arrived with Android 5.0 for HTC One M8 users and thereby improve the performance. The HTC One M9 is the newest flagship from the company that was released in April. It is all also set to receive the Android M update later this year.

The Android M OS is currently available as developer preview for users. Android M is expected to come preinstalled on the Nexus 2015 smartphone in October or November this year.
