The OnePlus 8 Pro’s color filter camera has been mired in a bubble of controversy ever since the phone launched. First, this auxiliary color filter camera was written off by many for largely being of no real use. Then, news emerged that the color filter camera was capable of seeing through thin plastic objects and very thin clothing too! Consequently, the camera was disabled in the next updates — first in China, and then even on global variants. The device even went on sale in India with the color filter camera disabled out of the box! OnePlus then finally fixed the Photochrom filter’s see-through issues with the OxygenOS 10.5.10 update by layering information from the sensor onto an image from the main sensor. But as it turns out, if you still really wish to use the auxiliary camera, you actually can as the color filter camera is still accessible through a simple ADB command.
XDA Member found out that the Photochrom color filter camera still remains accessible through the Factory Mode app on the latest update on the OnePlus 8 Pro. However, this app needs to be launched through ADB. Once the app is launched, you can keep it locked into the phone’s memory to access it without ADB. The best part about this discovery is that you do not need to be rooted or even have your bootloader unlocked.
To use the Color Filter camera on the OnePlus 8 Pro, connect your phone to ADB and run the following the commands:
adb shell am start -n com.oneplus.factorymode/.camera.manualtest.CameraManualTest
This will start the Factory Mode app. Once in the app, use the camera switcher icon in the bottom right corner to cycle through the different cameras. The color filter camera is positioned at number 4 within the app.
The question still remains of the camera’s overall utility. The x-ray/see-through effect can be reproduced only on very thin plastics. The overall utility of the OnePlus 8 Pro’s Photochrom color filter camera mode is very narrow in scope, and you are much more likely to appreciate its novelty just a few times and then forget about it altogether.
The images above are from Max Weinbach. I tried out the same on my OnePlus 8 Pro, and I could not locate any objects around me with a thin enough plastic shell to actually see-through. As far as clothing is concerned, the same results were observed. So the possibility of using this for nefarious purposes remains very, very limited, if at all.
