The Galaxy A51 is a little bit better than the Galaxy Note 4, with an 85.5 score against 81.6. Both phones we compare here use Android OS, but Galaxy A51 has newer 11 version and Galaxy Note 4 has Android 5.0 version. Galaxy A51 is a extremely newer cellphone, and it is also a little bit thinner and just a little bit lighter than the Galaxy Note 4.

The Samsung Galaxy Note 4 counts with a more vivid display than Samsung Galaxy A51, because although it has a bit smaller screen, it also counts with a greater pixel density and a higher 2560 x 1440 resolution. Galaxy A51 has much more storage capacity to store more games and applications than Galaxy Note 4, because it has more internal memory and an external memory slot that holds a maximum of 512 GB.

Samsung Galaxy Note 4 has a little faster processing unit than Galaxy A51, because although it has a smaller amount of RAM memory and a lower number of cores (although faster), it also counts with an additional graphics processing unit. The Galaxy A51 takes much better videos and photos than Galaxy Note 4, and although they both have the same 30 frames per second video frame rates and the same 3840x2160 (4K) video quality, the Galaxy A51 also has a lot bigger sensor which offers a way higher image and video quality, a larger aperture and a lot better 48 MP resolution camera.

The Samsung Galaxy A51 has greater battery life than Galaxy Note 4, because it has 4000mAh of battery capacity.

The Galaxy A51 costs a bit more money than Samsung Galaxy Note 4, but it's still a great choice, because you can get a better phone for that extra money.
