Marketing should always be OPT-IN by default, but these extra steps to opt out is truly asshole design.
Oh, and on the opt-out confirmation screen, you get two options: Yes or No. The button colour for "yes" is white, and the “no” button matches the “save” button on the previous screen, so it's easy to accidentally cancel the opt-out. Double-asshole design!
No? It's literally not a thing on any android. I just pretty extensively looked for any evidence of this online and I can only see people misunderstanding the feature of removing permissions for unused apps. One of the permissions apps are granted is storage, and that permission can get revoked if that feature is turned on. This does not delete stored data (it does not remove data the app has already written) but removes the apps ability to read or write to storage further, and can cause any temporary storage like cache to get erased. This will cause your accounts to get signed out and could potentially lead to data loss, but not because the operating system is actively and purposefully erasing data.
I was just talking about Samsung phones being a problem in general. Fuck Samsung.
