Soon after launching its 2013 flagship called the Galaxy S4, Samsung released a “rugged” variant of the same smartphone. It was called the Galaxy S4 Active only because of the fact that it is water and dust resistant, making it a good device to take up against the elements. It was never claimed that the Galaxy S4 Active could hold its own against a lawn mower but there's proof now showing its capable of that as well.
This story first appeared on reddit. The owner of this Galaxy S4 Active was mowing his lawn on a riding lawn mower while listening to music on his smartphone. It fell from his pocket and tumbled down under the mower. A blade hit the device and sliced out the top right corner.
Despite having cracks that run the length of the screen, the Galaxy S4 Active itself is still operational. The display is completely fine even though it took a hit from a blade. It never skipped a beat, the music continued to play and from the back it doesn't look like the device has suffered any damage at all.
Needless to say the owner was quite surprised by the robustness of this device as I'm sure you would be as well.
