OnePlus One was a well balanced device, but it did have some drawbacks. The flagship killer came with a single SIM card slot, which could have been a deal breaker for many. Given that most smartphones come with at least or sometimes even three SIM card slots, limiting to one SIM slot wasn’t a great idea.
But it looks like the OnePlus 2 will feature dual SIM dual standby. The company CEO, Liu Zuohu confirmed on Weibo that the new flagship will support dual SIM card slots. Unfortunately, we still don’t know whether there will be a microSD card slot too. We will even be happy to see a 3 in 2 Micro SIM + Nano SIM/ MicroSD card slot. But we are not sure of that at the moment.
Almost all the other specs have been confirmed, except for the display size and resolution. The OnePlus 2 will come with Snapdragon 810 v2.1, 4GB LPDDR4 RAM, 13MP rear camera with laser autofocus, USB Type-C port, fingerprint sensor and a new designed body (probably all metal).
The company will unveil the flagship on July 28, but expect a few more info before the launch. Meanwhile, you can check out all the things we know about the OnePlus 2 from this article. [source]
