If you're going to drop $1,400 on a top-of-the-line smartphone like the Galaxy S20 Ultra, you'd expect it to be tough enough to survive the abuses of daily life, wouldn't you? Thankfully, that appears to be the case. Both JerryRigEverything (aka Zack Nelson) and PhoneBuff have conducted durability tests for the S20 Ultra that suggest that it can handle a lot of abuse... though not all of it. JRE noted that the Gorilla Glass 6 screen doesn't scratch until level 6 on the Mohs scale (don't even worry about your fingernails) and was extremely resistant to bending. You might not want to leave it unprotected alongside your house keys, but this is much tougher than the fragile Galaxy Z Flip.
