<human>:  How do I upgrade my smartphone's operating system?
<bot>: First, check on your smartphone's manufacturer website if there is any available software update available. Most devices have an option for system updates either in the Settings menu, or under the Support or Software Updates section. If an update is available, download and install it. 2 Alternatively, you can connect your device to a computer and use a compatible software updater to check for updates and install them onto the device. Depending on the manufacturer and the system on your device, you may need to install additional drivers or download a compatible updater application.
