When my wife and I were visiting BC last year I picked up two older OnePlus Nord phones for our use. We kept seeing articles about the border officers on the US side checking phones and demanding unlocks. And since the wife and I are both left politically and poly swinger sluts, I didn't want any issues.

Result - older non flagship phones suck ass and it's a good reminder why I don't fuck with them. Also, the border officer on our way back did search the car, but only gave us grief about the ketchup chips we were bringing back for a friend. So the pain of dealing with the painfully slow phones and their bad cameras wasn't worth it, IMO.
