Reviews for the Samsung Galaxy A51 5G

Samsung Galaxy A51 5G Camera: Budget ultra-wide
Source: DxOMark English
With the Galaxy A51 5G, Samsung has pushed the price of a capable 5G phone into impressively affordable territory. However, it appears that affordability comes at the cost of imaging performance — to a degree. In the fiercely competitive mid-range segment, the A51 5G finds itself up against phones with superior cameras, and for a very modest increase in budget, there are options with substantially better imaging capabilities. However, buyers who are particularly attracted to Samsung’s approach or who want 5G speed on a strict budget will be able to wring acceptable photos out of the A51 5G. Heavy video shooters, on the other hand, should be wary of the autofocus issues our testers found. For stills shooters on a tight budget, the A51 5G may be worth a look.

Galaxy A51 5G review: Samsung’s cheapest 5G phone is a solid buy
Source: Sam Mobile English
The Galaxy A51 quickly cemented its position as a phone that you can’t really go wrong with. It’s a great mid-range phone and with all of the improvements that the 5G variant brings, it has become even better. At this price, there’s no reason why you shouldn’t buy the Galaxy A51 5G.
