keycap_puller It's an anti-tampering library running a special process with the zygote. It used to crash at launch prior to our 2026071100 which resulted in GrapheneOS always being allowed. It stopped crashing because we fixed all known compatibility issues with secure spawning in 2026071100. We've restored compatibility with apps using it by stopping it from running again.
This company wrote a library heavily depending on private APIs and implementation details. It results in apps using it not being compatible with future Android releases and GrapheneOS. The same thing applies to the Zimperium library we worked around in this release too. Both make assumptions about how things should be which aren't at all guaranteed. It's going to cause more problems in the future for every app using these when those apps break with a new major Android version. The whole concept shouldn't exist and the companies doing it should be taking on the burden of dealing with the mess they create instead of us.
