USB tethering allows you to share your phone’s internet connection with your laptop. This is extremely useful when you don’t have access to Wi-Fi and need to get your laptop online. When enabled, your phone acts as a modem, providing internet access via the USB connection.
To enable USB tethering, you typically need to go to your phone’s settings, find the “Mobile Hotspot and Tethering” section, and then toggle on the “USB Tethering” option. Keep in mind that tethering can consume significant battery power, so it’s recommended to keep your phone plugged into a power source while tethering. Also, check with your mobile carrier to ensure that tethering is included in your data plan to avoid unexpected charges.
MIDI
MIDI, or Musical Instrument Digital Interface, is a specialized mode primarily used for connecting your phone to musical instruments or music production software on your computer. It allows your phone to act as a MIDI controller, sending musical data to your computer for recording or manipulation.
This mode is specifically relevant to musicians and audio engineers who use mobile music creation apps. If you’re not involved in music production, you likely won’t need to use the MIDI mode.
Charging Only
In this mode, your phone simply charges when connected to the laptop. No data transfer or other functionalities are enabled. This mode is useful when you only need to charge your phone and don’t want any data connection established.
ADB (Android Debug Bridge)
ADB, or Android Debug Bridge, is a powerful command-line tool used by developers to communicate with an Android device. It allows you to install and debug apps, access the device’s shell, and perform various system-level operations.
ADB requires the installation of the Android SDK (Software Development Kit) on your computer and enabling USB debugging on your phone. This mode is primarily used by developers for testing and troubleshooting their Android applications.
