Furi OS was what turned me away. Never heard of it and that makes me realise we don't have an android alternative OS which is permanent. Do we have any OS which is permanent? Shouldn't we have one?
What do you mean by "permanent"?
My specific definition: 20 years later when a retired me boots up the device, it will be able to run the calculator app without shutting down.
That sounds like a hardware problem. But if the hardware works, why would you not be able to open any old app?
