Kyocera’s sapphire display is harder than we anticipated

Kyocera's sapphire screen is tougher than we expected

Few issues in life are extra satisfying than taking out pent-up aggression on a poor, helpless telephone, and the Kyocera Brigadier gave me that chance this week. Armed with a four.5-inch Sapphire Defend display, the rugged Verizon-unique gadget claims to be scratchproof and drop-proof as a result of the fabric is more durable than glass. Since an growing variety of producers (together with Apple and Huawei) are reportedly planning on utilizing sapphire on future merchandise, I needed to torture-check the Brigadier with lots of sharp and abrasive objects to see if it actually holds as much as its claims.

In an earlier piece, I mentioned that sapphire is 4 occasions as robust as glass and extremely scratch-resistant, however most smartphone makers are hesitant to swap Gorilla Glass out for it. Sapphire’s harder to supply, restricted in amount and prices extra; extra importantly, it is sometimes simpler to interrupt and more durable to bend as a result of the fabric is extra brittle. In fact, this was all based mostly on the claims of producers, so I did not need to simply take their phrase for it — I needed to check out an actual finish-consumer system.

Kyocera not solely inspired me to offer the Brigadier an in depth thrashing, nevertheless it additionally even despatched me a software package designed to assist me do exactly that. It got here with a pocket knife, metal wool and a bucket crammed with small rocks. This was an excellent begin, however it felt too… managed. In any case, an organization is not going to ship a torture package to reporters with out ensuring it passes with flying colours. So I introduced alongside loads of different sharp objects from my home to check out: scissors, a screwdriver, Brillo Pad, chopping knives, screws and keys.

As you possibly can see within the video, I used each single object with reckless abandon, urgent down as onerous as I might and scraping them throughout the whole floor of the display. I added screws and keys to the bucket of rocks, positioned the telephone inside and shook all of it collectively for 30 seconds. Colleagues got here in with knives of their very own to work out anger points. Lastly, as a final resort, I vigorously rubbed the telephone towards a protruding part of the brick wall in Engadget’s studio. Nonetheless, nothing.

Finally, it probably is not unattainable to scratch — even Kyocera calls it “nearly scratchproof,” which technically leaves some leeway — however you’d want a more durable materials, like diamond. Which means the sapphire display goes to face up to scratches from virtually each object that rubs or digs into it.

Glad, I subsequent turned to impression testing. I threw the telephone at a brick wall. I dropped it onto concrete, facedown, from waist- and chest-degree a number of occasions. I threw it excessive up within the air a minimum of 4 occasions. The case was in far worse form than the display itself; because the bezel is raised, the display is safely shielded from most drops. So I banged it towards objects that would impression the sapphire with out the telephone’s body getting in the best way: the highest of a metallic road pole signal, the nook of a number of tables and a few protruding partitions.

The decision? The display did not shatter, ding and even present any indicators of getting simply withstood a number of extreme blows. The case, nevertheless, was chipped and got here aside from the display in some locations, revealing a niche beneath. The facility button can also be more durable to press. The touchscreen continues to be surprisingly responsive, although oddly I now should press the facility button twice earlier than the lock display registers my contact.

At this level, I nonetheless have not been capable of bodily injury the display, and that is not ok — in any case, I got here into this check prepared to interrupt a sapphire show, and there are technically a number of methods to interrupt the Sapphire Defend. uBreakiFix, a smartphone restore firm, managed to crack the display by dismantling your complete telephone and dropping the sapphire panel from three ft with out its protecting casing; the staff additionally proved that it may possibly’t bend so far as Gorilla Glass earlier than shattering. Granted, you are doubtless by no means going to run right into a state of affairs by which you will use a Kyocera Brigadier show outdoors its casing — nor will you ever have to bend it that far — so are you able to break the display in an actual-life state of affairs?

I found that I might certainly inflict injury on the Sapphire Defend by dropping the telephone facedown from waist degree or greater onto jagged, pointy rocks (or comparable objects), as a result of they’re sufficiently small and sharp sufficient to penetrate the display. Even then, nevertheless, the telephone solely succumbed to some seen marks.

The sapphire display on the Kyocera Brigadier (which is at present $one hundred with a two-yr contract and $four hundred at full retail) is not invincible, nevertheless it does a lot better at withstanding drive and scratches than I anticipated. I’ve by no means seen a Gorilla Glass telephone stand as much as the sorts of relentless beatings I unleashed upon the Sapphire Defend. Congratulations, Kyocera — you’ve got made this sapphire skeptic a believer.
