Step by step

Tap Build number seven times
Go to Settings, About phone. Build number (CP3A.260905.009 on ours) is below Android version, part-way down. Android's instructions say to tap it seven times.

Find it in System
Go back to Settings, System. Developer options is under Advanced, below Backup. Tap it.

Check the switch
Use developer options is the switch at the top. It was on on ours. Turn it off to hide the settings again.
If you do not see this option
- No Developer options in System? Tap Build number again until the phone says you are a developer, then go back to System. Source: Configure on-device developer options
- Not under Advanced? On ours, Advanced held Backup and Developer options. Search Settings for Developer options if yours differs.
If this does not work
- Looking for RAM usage? Memory in Developer options said Memory profiling disabled on ours. Enable memory usage profiling was off, so it showed no figures.
- Want to hide it again? Turn off Use developer options at the top of the page. Source: Configure on-device developer options
