Answer 1

nokia with original pure android android one no built-in left software only pure android hardware super camera, battery, everything is fine for me in three months of use, the firmware has been updated 10 times, probably
1-lack of built-in left applications with harmful functionality
2-constant updates directly from Google
3-most importantly, when a developer develops an android application, its testing is usually carried out on a pure android, and only then from users of branded (remade) firmware, the developer learns about errors and fixes them so that everything works much more stable on a pure android
if you take a smartphone with a branded android, say from company X, then they take a pure android and remake it for themselves, hence the bugs, errors and lags, and when an update from Google comes out, they have to test and redo everything, sometimes they get bored and updates no longer come out
of smartphones with pure android one not so much yet but they have everything else for me is rubbish
