Your HiHi will automatically update itself to the latest version outside of office hours; usually between midnight and 4am providing that your phone is not in use.
To manually check that your HiHi has the latest software slide down the menu drawer in the top right corner, then press settings. Within the settings page, scroll down to the system section and press “About Phone”. Then press “Check for Updates” button. Your HiHi will then do a quick check. If there is a newer version of the software available, it’ll show in a pop-out dialogue window. Press “Install” to begin the update.
Depending on your bandwidth, HiHi will then take a few minutes to download the software and will reboot automatically. Once the new software is install, if you repeat the process, you will be notified that your software is up to date.
