Although it was earlier speculated that the Huawei Mate 30 Pro will have a circular camera setup on the back, it has now emerged that the phone might retain the same square grid as its predecessor, the Mate 20 Pro, although the specifications will reportedly receive a considerable bump, so the arrangement will not matter much. What might matter though is the fact that the Mate 30 Pro’s display might be one of the most ‘stand out’ components in a smartphone, even though a rumor suggests that its resolution isn’t going to be the crispiest.

According to an unconfirmed source from Max J, the Mate 30 Pro display will apparently have a 2600 x 1200 pixels resolution, which is much lower than that of the Mate 20 Pro, which has a 3120 x 1440 resolution. The display is also expected to have pronounced curves of about 90 degrees, something that was seen in a previous leak. Perhaps Huawei wants to reduce the resolution to optimize battery life considerably. Regardless, the leakster claims that you should treat this news with a hefty dose of skepticism, as it comes for an unverifiable source anyway.
