Unlike Apple Nokia built their devices to resist breaking and be 100% serviceable down to the smallest parts. Apple uses metal because it's significantly heavier than plastic and makes phones heavy enough to shatter glass screens and damage their internals when dropped. Any iPhone could replace its metal housing with an equally strong polymer and become exponentially more difficult to break.
The scratchproof "gorilla glass" (a Dow Corning invention) is extremely shatter resistant. Metal is of course more shatter resistant than polymer. There was a tragic brief era when we might have had synthetic sapphire / "transparent aluminium" screens: https://www.theverge.com/2019/5/3/18528920/sec-charges-apple... (sapphire is aluminium oxide) The 3210 era devices had easily replaceable polymer covers; they definite…
Yeah, but that doesn't help when the phone lands with the glass hitting something. And a heavier metal phone will have accumulated more kinetic energy during the fall than a lighter plastic one, so have a greater probability of shattering the glass.
