I went from a51 to a32. I much prefer the 32. There honestly wasn't much difference in the camera.

I'm SO GLAD I saw your comment. I'm in the same predicament and I think I'm going to go for the A32.

Well, this A51 does not support 5G. There is a separate model, A51 5G that does, but it's more expensive. For that reason, I am going A32.

Gotta go for the longer battery life of the A32. But dang. Really wanted the better camera in the A51. Samsung, what were you thinking when you took one step forward and two steps backward? Sigh.

I picked up the A51 and unless you are outside in BRIGHT light, the camera is a washout. My house is Low to Med light and the photos look like nicely done water color. I am so very disappointed, my phone is a glorified camera and that is why I went with the 'better' cam, but a cheap digital from Walmart would probably do a better job.
