If you suspect that the large, curved Infinity Displays on Samsung's latest Galaxy S8 series are easy to break, then results from a breakability test conducted by SquareTrade (a smartphone insurance company) support your hunch. SquareTrade's results indicate that the S8 and S8+ are significantly more fragile than their predecessors.

SquareTrade uses laboratory robots to conduct controlled impact testing (including dunks, slides, drops and tumbles) in order to assign a smartphone's breakability score. The higher a device's breakability number, the less likely it is to survive an impact.

In the case of the S8 series, SquareTrade found that the phones performed most poorly in the face-down drop test. Both the S8 and S8+ were cracked after one drop. Since the phones have all-glass bodies, they also were vulnerable in back drop tests: Falling back-down caused both phones to crack not only on the back, but onto the front as well. During a side-drop test, the S8 became more damaged than the S8+, losing some glass and interfering with button access.

The good news? SquareTrade's testing indicated that the devices' IP68 water resistance rating held true – both phones withstood 30-minute immersion. While there was some audio muffling immediately afterwards, audio returned to normal within another 30 minutes.

SquareTrade has recently moved to a 1-100 scale for its breakability test. (In the past, the scale ran from 1-10.) The Galaxy S8 received a 76 indicating medium-high risk, while the S8+ received a 77. Last year's S7 and S7 edge phones received a 5 and 6, respectively. (This is basically equivalent to 50 and 60 on the new scale, though the current model puts slightly more emphasis on drops.) For reference, the iPhone 7 and 7 Plus also received a 5 and 6 on last year's scale.
