This time I experienced my friend's Vivo phone's camera function, and I have to say that compared to it, the iPhone is starting to fall behind. Especially in portrait mode, various focal lengths and automatic lighting can produce photos that are comparable to studio-quality portraits without needing any third-party software, it's simply a must-have for girls. the iPhone has become less innovative since Jobs passed away, and its built-in AI features are quite lackluster. The only reason I would consider trading in for a new iPhone is -- battery 🔋 and security. Next time I go back to my country, I’ll get a Vivo as a photography and backup device.
