OnePlus 9 Pro could get an official waterproof rating

OnePlus has a love-hate relationship with the official dust and water resistance rating, better known as IP (Ingress Protection) rating. Although an industry standard and a feature much-touted by other smartphone makers, OnePlus has steered clear out of its way, explaining the unnecessary cost of the certification when its phones are just as dust and water-resistant anyway. That changed earlier this year with at least the OnePlus 8 Pro and it seems that its 2021 successor will likewise be favored by an official IP pair of digits.
