Use dedicated desktop platforms (such as Samsung DeX): Some phones offer a PC-like interface when connected to an external display via a Display Mode cable, giving the user a full operating system experience with changeable windows and a taskbar.
Relying on streaming and control applications (such as Link to Windows): These applications connect the phone to the computer or smart screen wirelessly, allowing the phone screen to be displayed and full control of applications and files using the keyboard and mouse.
Connecting a keyboard and mouse via Bluetooth: The phone can be turned into a simple and portable workstation by connecting a wireless keyboard and mouse directly via Bluetooth, and installing the phone on a suitable stand for browsing documents and writing texts easily.
Using cloud computing services: It allows running entire systems such as Windows via a web browser or custom applications on the phone, turning the screen into a window for massive computing operations and processing heavy tasks over the Internet.
