There's only one Android device that people will line up for like they do for the iPhone

OnePlus is a small Chinese tech company that has only released one device to date, the OnePlus One smartphone.

The One's successor, the OnePlus 2, is set for release on August 11. And people are already going crazy for it. 

In fact, it's one of the few Android phones that you'll ever find people lining up for like we see every year when the new iPhone launches.

That's because the OnePlus sells its devices on an invite-only basis, which garnered a huge amount of hype and demand. An invite guarantees you the opportunity to buy a OnePlus 2 device.

One of the main reasons why the One was in such demand was because of its high-end specs at an incredibly low $300 price tag.

The company is releasing the OnePlus 2 with the same invite-only system, and it reached the 2 million mark for reservations on Thursday.

OnePlus's co-founder Carl Pei told Tech Insider in an interview that they didn't want to make more phones than it had to, as it's a relatively small company compared to the likes of tech behemoths like Samsung, HTC, LG, and Motorola. At the same time, it's a genius strategy that creates a huge amount of demand.

Just take a look at these lines.
