Taiwanese smartphone maker ASUS has finally rolled out the Android 5.0 Lollipop Over the Air (OTA) update for ZenFone 4, ZenFone 5 and ZenFone 6 devices.

Though the company promised to release the update in May, it got delayed, as the smartphone maker had to update all its apps, Android runtime, along with the ZenUI interface over the original Android 5.0 Lollipop.

ASUS warns the smartphone might require a complete factory reset before the Android 5.0 Lollipop update, hence it is recommended to back up all the necessary data before downloading the update file.
