A friend wants to degoogle his phone, so I suggested the OS I'm currently using. The one we can't talk about... He wants a small/compact phone, so I suggested pixel 4a (not buying second hand though), but I'm afraid that planned obsolescence may kill the phone rather soon. What's your opinion?
I'm using a 4a right now which I bought last year, refurbished. It's a great phone and has a headphone jack.
If you're concerend about updates, install an alternative OS. If you want to degoogle that should be the path anyway.
