something about colour profile and a single pixel bricking phone!

(yes i watched it but it's a bit tricky to fully understand)

I killed a phone once with a wallpaper - it was a very-high-res (almost gigapixel, from memory) shot of the moon, which I rescaled to appropriate size for the phone, but it still died horribly.

The user interface kept crashing on reboot, so there was no way to reset the wallpaper back again - a factory reset from recovery mode fixed it, of course; and almost everything self-restored from "the cloud" with the exception of a couple of work-related 2FA tokens (which is pretty much what you'd expect).

I thought at the time I'd just not been careful enough with resizing the wallpaper and I'd blown the memory buffer size(s) or something; but who knows?

There are many, many cases on the internet with Android dying due to wallpaper - seems a little fragile if you ask me!
