Hi there. Please try the phone in safe mode and see if you can access the settings. This safe mode disables 3rd party apps and allows you to test the phone without interference.

The process for turning on Safe mode is as follows:

Press and hold the Power button.

Tap and hold Power off.

When the Reboot to safe modeprompt appears, tap again or tap OK.

Your device will then restart and it will say “Safe mode” in the bottom-left corner.

Welcome to Android Central! Also, not every manufacturer enables the System UI Tuner feature.
