[Update: Photographer speaks out] Some Android phones can be bricked using this wallpaper

Maintain you ever ever heard of these message strings or files that you just will be in a web disclose to ship to varied users to reason their cell phone to reboot? We’ve heard the story a pair of cases — mainly on iPhones — and now there’s a seemingly associated area affecting some Android gadgets. A easy image has the flexibility to refined-brick some Android phones if it’s space as the wallpaper, and we’re no longer completely obvious why.


Please make no longer save this your self.


Ice Universe, a leaker who focuses on Samsung products primarily, lately tweeted about an image file that became as soon as inflicting some smartphones — especially Samsung devices — to break and gentle-brick. What precisely is a refined-brick? That’s when the instrument can’t be light in a technique or one other, however will even be mounted the consume of somewhat easy suggestions comparable to deleting a file or resetting the instrument.

For reasons that aren’t completely determined, this easy image is inflicting some Android cell phone to break after which enter a say of being refined-bricked when the image is determined as a wallpaper. Upon being space, the instrument crashes and constantly turns the conceal on and off on the lockscreen. There’s no plan to leave this loop as even a reboot causes the cell phone to consume care of doing this after turning encourage on.

I examined this out on my possess Pixel 2 — another time, please don’t are trying it your self. Obvious adequate, the cell phone did precisely as described above after I space it as a wallpaper. Particularly, the image didn’t reason any problems when in the Google Photos app, so presumably, this isn’t the roughly area that can reason problems when the image is merely sent to a individual by process of textual disclose or email.

We strongly abet that you just don’t save this your self. We’re no longer linking or uploading the image itself for that reason. It’s likely you’ll maybe well notice in the video under what took place to my Pixel 2 unit as a results of setting the image as my wallpaper.

It appears to be like, even though, this doesn’t affect all Android smartphones. Android Authority says that a Huawei Mate 20 Pro they examined didn’t bask in any problems. Twitter users replying to Ice found that OnePlus phones might maybe maybe additionally be immune alongside with some gadgets from varied brands. The OnePlus Launcher applies wallpapers to the Android cell phone’s launcher most effective, no longer the machine, so that is gleaming.

Why might maybe maybe this be going down? In actual fact, we’re no longer obvious. It will most likely maybe well be that there’s some rotten metadata connected to this image that Android doesn’t play well with. I couldn’t collect any deliver proof of that, however I did collect that the embedded colour profile on this image references Skia, the graphics engine that Android uses. Would possibly maybe maybe maybe that be associated? I’m no longer obvious.

Ice notes in a tradition-up tweet that uploading the image to Weibo altered the colours a petite bit and, after that, it turn out to be threat free. Yet another individual found that altering the image perceived to prevent factors moreover. This fairly backs up the root it might maybe maybe most likely maybe well even be the metadata as uploading or altering photos can as soon as rapidly strip it of metadata.

Whenever you consume out to ignore our warning and save this for your self (seriously, please don’t), you wishes to be in a web disclose to increase your instrument by both resetting it completely (the consume of the bootloader) or by coming into stable mode and deleting the file from the instrument from there.


Update: After doing a petite bit digging, we’ve bought a petite more info to share on this area.

Our possess Dylan Roussel found that his Pixel 4 XL operating on Android 11 became as soon as no longer plagued by the area while a Pixel 3 XL on Android 10 became as soon as. He became as soon as in a web disclose to then resolve out what became as soon as responsible for problems.

Namely, that is a deliver with the colour condominium of this explicit image. In most cases, Android wishes to command sRGB, however this image uses the RGB colour condominium as an different. On Android 11, the machine converts the colour condominium (if it’s no longer already supported), however on Android 10 it does no longer. This isn’t a deliver with this image namely, as others might maybe maybe reason the associated deliver.

It’s likely you’ll maybe well read Dylan’s beefy thread for a more technical peek at what’s occurring behind the scenes, too.

… if the contemporary command supports it. If it’s miles no longer if truth be told supported, this would maybe change the Coloration Rental of the image to SRGB, and this would maybe log its contemporary Coloration Rental.

Ensuing from this it doesn’t break on the Pixel 4 XL. On the different hand, on the Pixel 3 XL with Android 10…

Update 6/3: Appropriate a pair of days after this area became as soon as revealed, Google is it sounds as if working on a fix. A mention in AOSP seen by Mishaal Rahman on Twitter reveals that Google already has an “internal solution” for the area which is being reviewed for the time being. It’s no longer specified what that fix is or how it’s miles going to come, however given we already know Android 11 patches this area, it appears to be like treasure this would be a fix coming to older variations.

Hi all, sincerely thanks for your contribution, we bask in got an internal solution under reviewing.


Update 6/10: About a days after the story broke, the distinctive photographer of this “cursed” picture has scheme out. Gaurav Agrawal says he shot the picture at St. Mary Lake in Glacier Nationwide Park in Montana. After taking the shot, Agrawal advised me that he edited it in Lightroom and exported in the “ProPhoto RGB” structure rather than favorite sRGB. Presumably, that’s the set up the deliver happened.

Agrawal has the distinctive picture uploaded on his Flickr story. He also took segment in a short interview with BBC on the subject.
