Why Use Guest Mode on Your Android Phone?
Google's guest profile feature on Android phones is particularly useful when you're lending your phone to someone temporarily. According to Google, "A guest profile is designed for someone using your device briefly." This profile provides a separate space on your device that can be easily removed once the guest is done using it.

With a guest profile, your personal files and private data remain hidden from other users, while still allowing access to the same Wi-Fi networks and Bluetooth devices as the main profile. If you plan to share your Android phone with someone else for a short period, activating the guest profile ensures that your files, messages, texts, emails, photos, and music remain secure from prying eyes.
