Comparison review
Galaxy A51 has a global score of 85.5, which is much better than Honor 9X Pro's 71.9 score. Although Galaxy A51 and Honor 9X Pro were only released 4 months apart, Galaxy A51 is thinner and lighter. Both phones in this comparison review have Android OS (operating system), but Galaxy A51 has 11 version and Honor 9X Pro has Android 10 version, so it gives lots of additional features and better performance.
Galaxy A51 has a bit better display than Honor 9X Pro, because although it has a bit smaller display, it also counts with a little bit higher resolution of 1080 x 2400px and a little higher pixels density. The Galaxy A51 has a processing unit that's very similar to Honor 9X Pro's processing unit, and although the Galaxy A51 has a lower amount of RAM memory, they both have a Octa-Core processing unit.
The Honor 9X Pro has a much better storage capacity for applications, games, photos and videos than Samsung Galaxy A51, and although they both have an external memory card slot that supports up to 512 GB, the Honor 9X Pro also has more internal memory capacity. The Galaxy A51's battery lifetime is just as good as the Honor 9X Pro one.
Samsung Galaxy A51 shoots just a bit better photos and videos than Honor 9X Pro, because although it has a tinier aperture, and they both have a same size sensor and a back-facing camera with a 48 megapixels, the Samsung Galaxy A51 also counts with a way higher (4K) video definition.
