The specific apps available depend on what's installed on your device.
Using cloud storage services: Services like Google Drive, Dropbox, OneDrive, and others let you upload files and then share a link to those files. This is ideal for larger files or when you need to share with multiple people. Recipients only need a link; they don't need the same app you used for storage. It often involves online access, though downloaded copies are possible.
Using Bluetooth: This is a good option for sharing files directly with another device nearby without needing an internet connection. It's usually limited to smaller files and transfer speeds might be slow. It's a good wireless choice if you're close by and the file size isn't too large. It's not as convenient as other methods for multiple recipients.
Using USB cable: You can connect your Android phone to a computer using a USB cable and then transfer files manually using your computer's file explorer. This gives you the most direct control over file transfer, enabling you to move files instead of just copying. It requires a cable and computer access.
Using file-sharing apps: Several apps specialize in sending and receiving files. Some apps might offer extra features like end-to-end encryption for enhanced security. These usually support several file formats and transfer methods, offering an additional convenient way to share.
Email: Attaching the file to an email is a common way, although limited by file size restrictions imposed by email providers. It's useful for recipients with email but less useful for larger files. It's widely used but may not be the most efficient choice for sharing.
The best method depends on the file size, the recipient(s), and your network connectivity.
