My Android phone keeps telling me to update my Android (though Google Play says nothing about an update). When I click on the message a website opens giving me four options for dowloading 9.11.0, depending on my "build" or "device" (e.g. ARM64 or x86_64 Device). The website also has a warning symbol indicating it may not be secure?
How do I know which version to download? How do I figure out my "build" or device type (on my Samsung A50 I found something about a "build" but it did not correspond to any of the options on this website).
