Comparison review
Galaxy A51 5G has a global score of 90.8, which is a lot better than the TCL 20 5G's 73.1 general score. Galaxy A51 5G's design is a little thinner and a bit lighter than the TCL 20 5G, even when both were only released 7 months apart. Both of these phones use Android OS (operating system), but Galaxy A51 5G has a newer 11 version while TCL 20 5G has Android 10.
Galaxy A51 5G has just a bit better performance than TCL 20 5G. Both of them have a Octa-Core processing unit and a 6 GB RAM memory. TCL 20 5G features a bit sharper display than Galaxy A51 5G, because although it has a bit less pixels per inch of screen, and they both have the same 2400 x 1080 pixels resolution, the TCL 20 5G also counts with a little bit bigger screen.
Galaxy A51 5G shoots a bit better photos and videos than TCL 20 5G, although it has a smaller aperture which is not favorable for low light captures and video, they both have the same 30 frames per second video frame rates, a same size sensor, a 48 mega-pixels camera in the back and the same video definition.
Galaxy A51 5G features a quite bigger memory to store more games and applications than TCL 20 5G, and although they both have equal 128 GB internal storage, the Galaxy A51 5G also has a slot for an external memory card that holds a maximum of 1000 GB. The Galaxy A51 5G has a battery duration that is just as good as the battery lifetime in TCL 20 5G.
