Try a Pixel rather than a Samsung. Despite being from Google (whose main schtick is advertising) it’s a pretty clean experience, while my family members’ Samsung and LG (who have since exited the market) devices have pre-installed, unremovable apps, stupidly hard-coded configs and - esp in the case of Samsung - often seem add new bullshit in after updates.
Samsung in particular pisses me off given how they charge a premium for devices that are full of intrusive bullshit.
