Re: Surely
Yes, it would be very similar with all Android OS mobile phones - which as you say, Pixels and high-end Samsungs use, but also low-end Samsungs, middle-of-the-road Samsungs, Motorolas (high, low, and mid), Xiaomis and most other Android OS mobiles made in the last few years.
Bottom line is, if you don't have the specific Google account details to log in (ie previously registered to the device), you would find it very difficult or very costly to access any of the info belonging to the user who hadn't wiped it.
