ASUS has been working on its custom Android skin for years, named 'ZenUI.' The fourth major version first appeared on some Zenfone 4 devices, but a few in that line were still rocking ZenUI 3. One of these was the Zenfone 4 Max, and now ASUS is finally getting around to updating it.
An over-the-air update has started to roll out to the Zenfone 4 Max, with the highlight feature being ZenUI 4.0. That means the interface should look cleaner, and there are fewer pre-installed apps. Here's the full changelog:
- Upgrade system user interfance to ZenUI 4.0
- Enable CHT/FET/TST VoLTE & FET VoWIFI function
- Improve double tap to sleep/wake feature
ZenUI updates are not related to the underlying Android version, so the phone is still running Android 7.1.1 under the hood. ASUS has promised to update all Zenfone 3 and 4 devices to Android Oreo by the second half of 2018. You can find more information about this update at the source links below.
