It’s usually screen size monster specs that make news for smartphones, but the Oppo R5 is conquering a different category: thinness. 

Oppo’s latest is staking claim to the “world’s thinnest smartphone” title. The Oppo R5 comes in at 4.85mm (0.19-inch) thick, beating out the current king, the 5.15mm Elife S5.1. Sure, the Chinese manufacturer isn’t selling it here in the U.S., but it’s at least worth seeing how manufacturers are pushing smartphone design to more extreme limits. (For a more common comparison, the ione 6 measures in at 6.9mm.)

To compensate for that razor thinness, the Oppo R5 needed to make some compromises on the spec sheet. There’s only 16GB of internal storage no microSD expansion slot, so you can’t splurge on too many of those Humble Bundles. 

There’s also no headphone jack. To make up for this, Oppo bundles in a micro-B adapter so you can plug in, though that means making sure you grab it before going out for a run. Instead, the most practical solution is a set of Bluetooth headphones.

The other specs are respectable, as the Oppo R5 has a 5.2-inch HD AMOD screen, a 64-bit Snapdragon 615 processor, 2GB of RAM, a 13Mcamera (5Mfor the front-facing, selfie cam), a 2,000 mAh battery, E radio. 

y this matters: One company’s innovation is another’s next idea. Samsung, HTC, , Motorola—which make the bulk of Android phones sold in the states—are always looking for the latest edge. The current race is for the largest screen, with the Note 4 Nexus 6 screen sizes close to six inches. It would be a win for consumers if someone went against the grain focused on making a phone with less instead of more.
