We know OnePlus is working on a 5G phone, and the 7 Pro could be the variant which supports the next generation network, and thus carries a loftier price tag.
Also Read: OnePlus 7 Pro is coming soon! Although that's certainly a specific projection, Agarwal doesn't make it clear if he's referring to a global announcement date or an actual commercial launch. This goes in line with OnePlus' launch schedule but there's no official confirmation as yet.
A fairly reputable source just came out with an exact date of when the OnePlus 7 will come out.
As far as the rear cameras are concerned, OnePlus 7 is expected to get a triple camera setup with a 48-MP primary shooter having a Sony IMX586 sensor.
We can also see some information about the phone in the leaked image, specifically that it runs on the high-end Qualcomm Snapdragon 855 chipset, has 8GB of RAM and 256GB of storage, and has software based on Android 9 (Pie). According to a report by Repubblica.it, OnePlus CEO Pete Lau said that folding screens do have potential, but not in phones, not with the current technology.
