The OnePlus 8 Pro comes with a quad-back camera setup, with the 48MP Sony IMX689 capable of seeing at least part of the infrarot spectrum, although it was used only for one thing: a Photochrome color filter mode.
After the phone was released some folks found that in some cases color filter mode could see through certain types of plastic and fabric. OnePlus said after that news cycle that it would disable the feature in Hydrogen OS (the Chinese version of its ROM)
In the Chinese variant of the handset running HydrogenOS, the company announced it would be disabled. But incidentally, it was also disabled by the brand in the global version via OxygenOS 10.5.9 OTA. But now, through new update to OxygenOS 10.5.10, it is re-enabling the ‘photochrome’ filter.
Bundled with OxygenOS 10.5.10 for the OnePlus 8 Pro, the updated OnePlus Camera (version 4.0.267) carries a property to disable the Color Filter camera on India units, as reported. The camera app is found to have the latest property associated with the China and India units for both IN2020 and IN2021 model numbers, respectively.
Interestingly, the update changelog makes no mention of re-enabling the photochrome filter in the camera app. Having said that, this change applies only to the global handset variant
If you don’t want to lose what OnePlus has offered through the color filter camera you shouldn’t install OxygenOS 10.5.9 on your OnePlus 5 Pro.
But if you’re worried about how to use the extra camera to give you slightly enhanced visibility to see through some objects , particularly those without infrarot shielding, then you can go further and download the latest updates.
