Because of the unwritten rule that only two-year-old devices will receive the latest Android OS, many HTC users have expressed concern that the HTC One M8 may be included among the list of Android devices which shall not be able to take on the Android M when the OS is officially made available to the public later this year
But HTC senior vice president for product management Mo Versi, assured the users of HTC One M8 that the device will update to Android M.
HTC One M9 has no problem with the upcoming Android OS since it is still within the unwritten rule.
At the moment, the HTC One M9 comes out of the box with Android 5.1 Lollipop on it although when it was launched in March and released to the market the following month, it came out with Android 5.0.2 Lollipop.
The HTC One M8 has been updated to Android 5.0.2 Lollipop also in April this year and users now have the option to take on the Android 5.1 Lollipop update over-the-air.
The Android 5.1 Lollipop has delivered new improvements and enhancements to the HTC One M9 and HTC One M8 including the so-called new Material Design from Google.
