Model Name: Zenfone Live L2 ZA550KL Firmware Version: WW-16.07.1907.408 Rooted or not: NOT OS: Android 9 Beta Maybe what I write can help Asus in development. I updated my OS to Android 9 Beta and found some bugs. Here are the details: 1. The screen scale is not full. Edges are missing a few pixels around 1 to 2 pixel. 2. Some displays do not fit, such as the date on taskbar. 3. Some items look big (in my personal opinion).
