The BOOKOO N app is designed to operate normally without automatically turning off the screen. If you experience the screen dimming or turning off while using the app, it is usually related to your phone’s system settings, particularly battery optimization features or power-saving settings.

Solution：

1. Check if battery optimization or power-saving mode is enabled on your device.

2. Adjust phone settings if you want the screen to stay on continuously.

If you prefer not to change system settings, the app cannot guarantee a “always-on” screen at this time.
