This is a more general question

This is a kind of general question. I notice that many new flip phones - for example the Alcatel Go Flip 3 - use pretty much the same keypad layout as the old Motorola RAZR v3. I’m wondering anyone knows if that means they are likely using the same keypad connectors and/or interface for the keypad? I’m wondering if it might be possible to build a Frankenphone with new guts, but in a Razr case?
