We've tested extensively for durability in-house, and one of the reasons we went with the metal frame was to provide drop resistance. The combination of plastic shell + metal frame protect the screen/keys/camera module very well from their functionality being harmed.
So you didn't experience any serious damage to screen or vital parts of devices during this durability testing?I think we need to have some guy like JerryRigEverything (check out his youtube channel) but for testing only hardware wallets
We're also working on accessories for our next device for these very reasons. Excited to announce it all when the time is right 
Now you got me interested, just don't go with BlackBerry style device please
