OnePlus accidentally fired an over-air update that disables a filter that can see through some thin black plastic and in some cases clothing.
Although OnePlus said on May 19 that it would temporarily disable the filter in the Chinese version of its operating system in an update, the company had not planned to remove the filter from its global software. Instead, OnePlus said it would update the filter. The latest update removed the filter for people outside of China anyway.
The filter, called “Photochrom”, creates an X-ray effect by using the infrared sensors built into the OnePlus 8 Pro to capture light that is not visible to the human eye. The feature was intended to be used to create interesting images. But it was scrutinized when people realized that they could sometimes see through clothes.
You can take a look at how the filter looks through black plastic in the pictures at the top of this post, taken from a video shared by Ben Geskin on Twitter. And you can get an idea of how the filter can look through a thin black T-shirt in this video by Unbox Therapy.
The limit also experimented with the feature and found that “it only works on very thin black plastic that is already a bit transparent in the right light” and that it is “hit or miss” with clothes.
The Photochrom filter was removed “temporarily for adjustment,” according to update notes seen by Xda-developers. The notes also said that the filter was expected to return “around June” without revealing an exact time Xda-developers. One user on OnePlus forum reported seeing similar update notes. Android Police installed the update and confirmed that the Photochrom filter had been removed.
“This OTA inadvertently went to a limited number of devices,” a OnePlus spokesman said in a statement to The limit. It will be reactivated in the next air update, the spokesman said. OnePlus also shared this statement on their forums.
