It’s in the article :
“Samsung’s Auto Blocker feature takes things a bit further.The feature, fully blocks the installation of apps from unauthorized sources, even if those sources were granted the REQUEST_INSTALL_PACKAGES permission.”
Why is the post title so click bait when the article only talks about mutation testing which is just a specific testing technique? A lot of testing is still done manually not even automated, it might be possible to automate test suite creation with generative ai and it’s already being done in the field but nobody really want tests that might be wrong which is the whole point of testing.
I don’t have a Samsung but I would imagine that this only blocks new installations and looks like that it can be easily disabled if you don’t want it
