The OnePlus 7 Pro is being announced tomorrow. Here's everything we know so far about what could be one of the best smartphones of the year.

• OnePlus is announcing its new OnePlus 7 "Pro" smartphone on May 14.
• The company has already released a few details of what to expect in its next big smartphone.
• As with any unreleased smartphone, if there aren't facts, there are rumors. Check out what we know and heard about the OnePlus 7 series. 
• Visit Business Insider's homepage for more stories.

Rather than letting the rumor mill conjure up a bunch of things about its upcoming smartphones, OnePlus has offered at least a few details up front.

We know for a fact that OnePlus is releasing a OnePlus 7 "Pro," but a regular OnePlus 7 model is still stuck in the rumor mill. 

Below, you'll find everything we know about the OnePlus 7 Pro and the regular OnePlus 7, starting off with things we know and tapering off into good old-fashioned rumors. Surprisingly, there are more confirmed specs and features for the OnePlus 7 Pro than there are rumors.

Check it out:

We know the OnePlus 7 Pro will have a "super smooth" display.

OnePlus CEO Pete Lau told The Verge that its upcoming OnePlus 7 Pro will have a "super smooth" screen. 

By "super smooth," Lau's comment could be tied to the rumors that OnePlus's upcoming smartphone will have a 90Hz refresh rate (most smartphones have a 60Hz refresh rate). That's to say the OnePlus 7 Pro display will have a "smoother" appearance than most smartphones when swiping around the device.

We know the OnePlus 7 Pro will also have a "very crisp" display.

Lau also told The Verge that the OnePlus 7 Pro's screen will be "very crisp," suggesting it'll have a sharper display than previous OnePlus smartphones. 

With that in mind, we might deduce that the OnePlus 7 Pro will have a 1440p resolution display, much like other flagship Android devices. OnePlus smartphones have typically had 1080p resolution displays. 

We know the OnePlus 7 Pro will have 5G connectivity.

Lau also confirmed to The Verge that the OnePlus 7 Pro will have 5G connectivity.
