While the A03s is very cheap, the Realme 12 Pro+ represents an enormous leap in nearly every aspect of the smartphone experience. The Snapdragon 7s Gen 2 chipset offers a massive increase in processing power, making the phone smooth and responsive for everyday use and mobile gaming. The AMOLED display is simply gorgeous, with vibrant colors, deep blacks, and a fluid 120Hz refresh rate - something that the low quality LCD of the A03s simply cannot compete with. The cameras are fantastic, with a versatile setup that can handle various lighting conditions and zoom levels. The faster charging is essential for modern, busy lives. While the cost is higher, it is not an order of magnitude higher, and you're getting a device that's simply miles ahead of the A03s. The A03s is really only suitable as a backup phone, or for those who have a very small budget.

The Realme 12 Pro+ is a far more capable and future-proof device, offering a much better experience in almost every aspect, and so it is well worth the extra investment.
