I have a stock Motorola g6 on Android 9 with the latest security updates.
I wanted to further reduce the UI scale from "smallest" and found the smallest width option in developer options.
Increasing it above roughly 500 causes a series of glitches.
The Motorola Launcher keeps crashing with unavoidable app not responding texts. This makes the UI very hard to navigate through.
The System UI also crashes with occasional errors making the phone laggy and unresponsive.
The Motorola UI is also disabled reverting to stock Android. This includes the Moto app.
Reverting the setting to any number only partially solves the errors. Using the accessibility tab to change the UI scaling fixes it completely.
If there is anyway to further reduce the UI scaling without this glitch, I would love to know.
