Huawei is on the verge of releasing its first major smartphone since being blacklisted by the US. Here's everything we know about it so far.

The announcement date is set for September 19.

Huawei will announce its Mate 30 series of smartphones on September 19, the company recently posted on Twitter. It's unclear when the new devices will actually be released, but last year the Mate 20 and Mate 20 Pro were available to purchase in some markets on the same day they were unveiled in October. The larger 7.2-inch Mate 20 X launched a few days later.

It's unclear whether it will have Google's Android.

Considering Huawei has not been removed from the US Commerce Department's Entity List, there's a possibility the new phone won't be able to use Google's Android software or the search giant's popular collection of apps, like Maps and Gmail.

A Google spokesperson recently told Reuters that the Mate 30 cannot be sold with Google's software and apps because of the blacklisting. Huawei also said in August that it wasn't sure whether the Mate 30 would be able to run on Android when asked by Business Insider.

But Huawei's Vincent Pang said during a media event at the end of August that the company doesn't have any current plans to launch a new smartphone powered by its own Harmony OS operating system, per CNET. That suggests it plans to stick with Android for upcoming launches like the Mate 30.

The phone may have four cameras arranged in a circular cutout.

The P30 smartphone that Huawei unveiled earlier this year has four rear-mounted cameras, and there's a good chance the Mate 30 will inherit that quad-camera arrangement, too. Unlike the P30, however, the Mate 30 is expected to include a circular cutout on the back, as shown in leaked images from Pricebaba and prominent gadget leaker Steve Hemmerstoffer.

Huawei's teaser for its September 19 event further fueled such speculation, since it prominently features a circle that resembles a camera.

It could also have a 6.6-inch curved display.

The leaked renderings from Pricebaba and Hemmerstoffer also suggest the phone will have curved edges and a 6.6-inch display. Like the Mate 20 Pro, the Mate 30 Pro will also reportedly have a wide notch near the top of the screen for its front-facing cameras.

It will likely run on a next-generation Huawei processor.

Huawei typically develops its own processors for its smartphones, much like Apple, and the Mate 30 is likely to be no different. Since the P30 and Mate 20 both run on Huawei's Kirin 980 chip and its Mate 10 predecessor is powered by the company's older Kirin 970 processor, it's looking like the Mate 30 will feature a new Kirin 990 chipset. The Mate 30 will also work with 5G networks, according to Reuters.
