The Quick Menu is your fast lane to the settings you reach for most: brightness, performance mode, shaders, USB mode, and power options. You can open it from the home, and you can raise it right over a running game without quitting.
Opening the Quick Menu
- On the home, the Quick Menu is the far-left category (the power-icon column). Move to it like any other category.
- Over a running game or app, hold Power to raise the Nano overlay, which opens straight on the Quick Menu. Press B or hold Power again to drop back into your game. See the in-game overlay.
- Holding Power on the home jumps directly to the Quick Menu's Power submenu.

| Power | A submenu: Restart, Power Off, Recovery, Safe Mode, Boot Android |
Performance Mode
Three profiles trade battery for speed:
- Normal scales up and down with load (the everyday default).
- Max Performance holds high clocks for the most demanding games.
- Power Saver keeps clocks low for light emulation and long sessions.
Global Shaders
The Global Shaders item applies a system-wide display shader over everything on screen. Pick a preset and tune it:
- Off turns shaders off.
- CRT adds scanlines (adjust Scanline Size and Scanline Strength).
- LCD3x and LCD emulate an LCD grid.
- Blur Fill fills the empty sides of a non-fullscreen image (with a Resolution and Orientation control).
- Custom Shader loads your own preset, with Resolution Scale and Scanline Density controls.
If a shader ever makes the screen unreadable, hold Power + Select to disable it instantly. See Controls.
Quick Settings tiles
The Quick Settings page is a grid of one-tap toggles, including Wi-Fi, Bluetooth, Performance Mode, Global Shaders, GammaRGB, GammaEQ, Screen Map, Deep Sleep Mode, External as Primary, ABXY Swap, D-Pad/Analog Swap, Global Sensitivity, and stick inversion. Tap one to flip it. The unused Immersive Mode and Analog Calibration tiles have been removed to keep the grid tidy.
USB Settings
Switch how the device appears when plugged into a computer:
- Charging only (default): no data connection.
- MTP: browse the device's files as media storage.
- PTP: transfer photos.
- RNDIS: share the device's connection as USB Ethernet.
For a simpler two-way choice, Settings > USB & Docking offers File Transfer (MTP) and Charge Only, which is the quickest way to move files to a PC without ADB. See the Settings Reference.
To silence the launcher's UI navigation sounds, use the Navigation Sounds toggle in Settings > Sound Settings (the boot jingle still plays).
Where to go next
