Frequently Ask Questions

Is the Samsung A51 a good buy?

The Galaxy A51 still has decent hardware, and if you don’t mind scraping your fingerprints against a slab of glass all day, the Exynos 9611 processor and 4GB of RAM should suffice.

Sure, it’s a bit pricey if you intend to use the phone for many years, but you get what you pay for.

What's the problem with the Samsung A51?

The Samsung Galaxy A51, like many of its fully-baked smartphones, is an amazing device with great capabilities, however, some users have reported a couple of Samsung Galaxy A51 Issues on the internet.

Among the reported faults are keyboard troubles, display difficulty, and a slew of others.

Is the Samsung A51 still a good buy in 2021?

However, putting money down for the Galaxy A51 in mid-2021 isn’t a good idea unless — once again — you can locate it for less than half the initial price.


It’s simply no longer worth paying full price for it in the wake of so many 2021 Galaxy A phones boasting 5G and high refresh rate displays.
