Inspect what exists
Open the actual settings screen and list only the options shown by your selected app and device.
Choose one change
Adjust a supported control, sound or graphics option and repeat a similar task. Keep the rest of the setup stable.
Record the result
Describe what you observed without calling a subjective impression a benchmark. If the result is unclear, say so.
Return safely
Use supported settings and provider instructions. Do not disable device security to follow an unexplained installation prompt.
