I thought the idea of cassette futurism is to show fictitious retrofuturistic tech. Specifically how 70s and 80s tech would look like in the (far-) future. and not how the actual tech looked in that time period, no matter how futuristic it looked back then.
What i expected to see was Alien and Blade Runner aesthetics and not GameBoy and Commodore. As it is now, it is simply “pictures of old tech”.
Yes and no. e.g. see https://grapheneos.org/usage#carrier-functionality
And https://grapheneos.org/usage#lte-only-mode
So… it depends
If your carrier is official supported by google, your carrier itself supports it and your device is not imported, it is likely to work.
