Personal Choice and Rationale

If I had to choose between these two phones, I would choose the Xiaomi Poco M4 Pro. While the Samsung Galaxy A12 has a telephoto lens and depth camera, the overall experience offered by the Poco M4 Pro is far superior in nearly every other aspect.

My reasoning is based on several factors:

1. Display Quality: The AMOLED screen on the Poco M4 Pro is a massive upgrade from the PLS LCD on the A12. The higher resolution, pixel density, and refresh rate will dramatically improve the viewing experience, which is crucial for daily use, including reading, watching videos, and gaming.
2. Performance: The Helio G96 chip in the Poco M4 Pro offers significantly faster performance compared to the Helio P35 in the A12. This is evident in the AnTuTu scores, which show that the Poco M4 Pro is 326% faster, resulting in a smoother and more responsive user experience.
3. Fast Charging: The 33W fast charging is much more convenient than the 15W charging on the A12. It greatly reduces charging time and improves usability.
4. Audio Quality: The inclusion of Dolby Atmos, Hi-Res Audio, and stereo speakers on the Poco M4 Pro provides a far superior audio experience, particularly for multimedia consumption.
5. Connectivity: The Poco M4 Pro offers the latest Wifi and Bluetooth standards which will provide more reliable connections and higher quality audio for compatible devices.

Although the Samsung Galaxy A12 has its appeal with the telephoto lens and depth camera, I find that its inferior performance, display, and audio significantly impact the overall user experience. The Xiaomi Poco M4 Pro is a more well-rounded phone that I feel will be better for the majority of users. The lack of information on its internal storage and RAM options is a concern, but the overall offering is still superior to the Samsung A12.
