My Choice

If I were to choose, I would go with the ZTE nubia Red Magic 9S Pro. My reasoning is as follows:

• Future-Proofing: The cutting-edge Snapdragon 8 Gen 3 chipset in the Red Magic 9S Pro provides substantially better performance for current needs and ensures that the device will remain relevant for longer. The A12's performance is already dated.
• Superior User Experience: The 120Hz AMOLED display, significantly better camera capabilities, much faster charging, and superior audio quality all contribute to an overall premium user experience that the A12 simply cannot match.
• Versatility: The Red Magic 9S Pro handles both basic tasks and demanding applications with ease making it versatile for a variety of different user needs.
• Value Proposition: Despite the higher price, the Red Magic 9S Pro offers a much better price-to-performance ratio and is a significant improvement in nearly all aspects compared to the A12.
• No Trade Offs: While the weight is slightly higher, the improvements to nearly every other aspect make the additional weight negligible for me. The loss of the telephoto lens is not a significant factor given the drastic improvements in all the other cameras.

While the Samsung Galaxy A12 might be adequate for basic use and a very limited budget, the ZTE nubia Red Magic 9S Pro offers a far superior experience, making it a much better option for anyone who wants a high-performing, reliable device.
