I've never seen anything as aggressive as what the parent describes on either Samsung or Xiaomi.
Xiaomi is the worst, selling top spec phones for dirt cheap by subsidizing them with ads, but even they never ruin your battery life by spamming ads all over the place. Plus, you can turn them off during setup, but most people just hit next to get the annoying setup screens to disappear it seems.
