Cannot Update Kodi on Android Box

I have an Andorid Box, I am sure I do. It’s from a company called VMedia that supplies IPTV, and on it there’s already KODI software but no where in the KODI setting can I install the update as it currently has 14.2 on it. I tried to go to the browser but have been unsuccessful. Is there another way to update the software? I cannot do it from the settings etc. Thank you.
