Before a certain Android version it was pretty common for Aliexpress sellers to plant unremovable ads, third-party stores, and god knows what else into the otherwise clean firmware, to be able to sell the phone with a discount. They usually didn't deny it, or even genuinely wondered - what's wrong with it? You bought it for a cheaper price after all, you should be happy, the seller is happy, everyone is, have a nice day sir. (a real conversation I had years ago)
