Personal Choice
If I were choosing between the Oppo A57 4G and the Xiaomi Poco F4, I would go with the Xiaomi Poco F4. The performance difference is just too substantial to ignore. The Snapdragon 870 chip is a beast compared to the Helio G35. I would definitely choose the more vibrant screen, with its better brightness and much higher refresh rate. For me, having a smooth, responsive user experience with a great display is essential, even if it means slightly less battery life (which is still good enough on the Poco F4).
I also value the significantly improved camera capabilities and video recording features. Having the flexibility of a wide-angle lens and being able to shoot stable 4K video would benefit my use cases quite a bit. Additionally, the faster charging speeds make a real difference in day-to-day usage.
While the Oppo A57 4G is a decent budget phone, the Poco F4 provides a far more complete and enjoyable smartphone experience for most users.
