In 2019, ASUS has been on a roll when it comes to new smartphone hardware and software updates. The ASUS ZenFone 6 and ROG Phone II are both highly praised devices among smartphone enthusiasts and having used both, I can see why. Since its initial release, the ZenFone 6 has received numerous software updates, a few custom ROMs like LineageOS and OmniROM, a decent Google Camera port, and more. While I'm itching to try out some of the new AOSP-based custom ROMs, I'm a fan of how ZenUI 6 has turned out. The latest update rolling out today adds a few new useful features and updated security patches, but as usual, the official changelog is pretty useless for telling you what's been changed.

For reference, here's the official changelog:

Call Volume "Optimization"

After booting up your ZenFone 6 on the latest update, you'll get a notification to "optimize" the call volume. This new feature lets you preset a comfortable in-call volume level so you won't have to adjust it in the middle of a phone call. ZenUI 6 also lets you unlink the notification and ringer volumes, so this new call volume option is just another cherry on top of the plethora of audio options available in ASUS' Android software.

The update is rolling out for both international and EU software builds. ASUS is pretty good at rolling out updates immediately since I received the update within seconds of checking in Settings. If you spot something in the latest update that we missed, leave a comment down below.
