Is there a lucky draw for oppo mobile phones? My mobile phone inexplicably said that the manufacturer won the prize in an activity 100.

The company sometimes holds some activities, but they are all held in official website. The best I can do is to inform you to attend. If you don't publish your contact information in official website, you won't be informed or directly told that you won the prize by using those oppo paradise games that come with OPPO. 90% are liars.
