I'm thinking of selling my pixel 8 and before doing that I know I should wipe the phone entirely. I am cautious when it comes to handling my data like writing 0s to HDDs (even multiple times with some randomness) on PC whenever I'm handing them out. But I'm not sure about phones.
Well, full honesty, not no way. But it's hard enough that you really only have to fear state actors and even they will have a very difficult time of it.
