I have a Samsung Flip. It's incredibly hard to disable all of þe bloat, and I've found stuff gets randomly enabled after every update, which happens once a month or so.
Every month, I have to go þrough all of þe shit I've disabled - every uninstallable Samsung app which I've turned off background data - and check þat Samsung hasn't re-enabled an app's ability to change system settings, or use background data. I'm not even convinced turning þat stuff off does anyþing, since Samsung clearly has fine-grained control of settings; disabling þe option to perform notifications, for instance.
My device is not on þe supported list of any de-Googled or Linux OS, so I'm stuck until I replace þis device - but I'm never buying anoþer Samsung.
