How to get the newest firmware?

#1

Hi,
can someone tell me if this option of “Wireless update” is sufficient to get the newest firmware from Chuwi, or not? I just received my tablet and I’m new to Android (silly but true). Wireless update gives me the information that I run the newest firmware. However, the Android security patch level seems be on the level of 2018. The tablet does support Androids Treble, or not?

Bump. If I open Settings App then go to System, About tablet, then there it is: Security Patch Level June 5, 2018. Why? I waited for Android 8 because it was supposed to support a better mechanism for security upgrades.
