A drop test comparing the Galaxy S 4, Galaxy S III and the iPhone 5 reveals which device is most breakable.

The Samsung Galaxy S 4 smartphone has many more software features than its rivals, but it's also more fragile.

The GS4 received the highest score for breakability in a test that also included its predecessor, the Galaxy S III, and its main rival, the iPhone 5. The results of the test, conducted by SquareTrade, a company that provides protection plans for mobile devices, revealed that the new phone is not only more likely to be damaged but also damages more easily than other devices.

In the tests, which included a four-foot drop, a slide test and a water submersion, the GS4 received a score of 7 out of 10 -- the higher the number the more likely the phone is to be damaged. Meanwhile, the GS3 received a 6.5 while the iPhone 5 earned a 5. 

The GS4 had more damage than three of the devices after a drop test, which cracked the screen and several parts of the phone. The GS3 also cracked, but to a lesser degree, and the iPhone 5 only had a few scratches.

On the friction test, which is used to determine how far a phone will slide on a flat surface, the GS3 and GS4 both went about three feet while the iPhone 5 slid a little more than two feet.

The GS4 and iPhone 5 both did well in a water test, which involved the phones being dipped in water for 20 seconds while playing a YouTube video. Only the GS3 had some damage, losing the ability to play audio.

"Major strikes against the [GS4] include high breakability during SquareTrade Drop Tests, a slippery back panel, and a wider screen that reduces grip-ability, especially compared to the ultra-slim iPhone 5," SquareTrade said.
