Enable Developer Mode
Developer Mode unlocks Developer Options on your Android device, which is required to enable USB debugging. The steps vary slightly by manufacturer.
Stock Android / Google Pixel
- Open Settings
- Go to About phone (or About tablet)
- Tap Build number 7 times
- You'll see "You are now a developer!"
- Go back — Developer options appears under Settings → System
Samsung Galaxy
- Open Settings
- Go to About phone → Software information
- Tap Build number 7 times
- Enter your PIN/pattern when prompted
- Developer options appears under Settings (scroll down)
OEM unlocking in Developer Options is NOT required for USB debugging — it's only needed for bootloader unlocking. If it's greyed out, that's fine — just enable USB debugging.
Boox (Palma, Tab Ultra, Note Air)
- Open Settings
- Go to About device (or Device info)
- Tap Build number 7 times
- If that doesn't work, try tapping the Serial number 7 times instead
- Developer options appears under Settings
On older Boox firmware, the trigger is the serial number rather than the build number. Try both if one doesn't work. After a firmware update, Developer Options may reset — you'll need to enable it again.
Xiaomi / Redmi / POCO
- Open Settings
- Go to About phone
- Tap MIUI version (not Build number) 7 times
- Developer options appears under Settings → Additional settings
Xiaomi has an extra security setting. In Developer Options, you must also enable "USB debugging (Security settings)" and "Install via USB" — without these, ADB commands that modify settings or install apps will be blocked. Note: enabling the security toggle requires an active SIM card with data.
OnePlus
- Open Settings
- Go to About device
- Tap Build number 7 times
- Developer options appears under Settings → System
Daylight DC-1
- Open Settings
- Go to About tablet
- Tap Build number 7 times
- Developer options appears under Settings
