I’m thinking about picking up a used Samsung device. While I know that the likelihood of tampering in order to steal my data is low, how effect is a factory reset to making sure that my device is good to go? I’ve seen folks on here talk about buying refurbished in the context of a Pixel that will get GrapheneOS, but in the context of the average person just buying a used device.
Also, if you have any additional tips on things to check for when buying used, like diagnostic tools or settings to look out for, that would help!
Note: I know stock Samsung is not the best for privacy, but I still want to ask about Samsung specifically.
