It may seem odd that I rate this phone 'good' when it stopped working completely at a month, but during that time I was happy with it, so rate on anticipating that it is not a common failure. have given excellent customer services. The screen is clear and sharp; the screen camera good quality and good for video calls, but the three camera options have sharpness and night time below what I was hoping. Battery life is also not as long as expected (can be < a day). Call quality is clear and speed of operation fast enough. The uncovered phone is slippery in the hand, so I bought a cover, which solves the problem and protects the phone.

Verified Buyer

For the price it's a great phone only real complaints are 2 fold 1 the speaker sound tiny 2 the back plastic is a little creaky which is easy to fix as all phones are going to be in a case of which I'm waiting but for the price you can't really complain about minor things this is my 2nd à series phone start with the a20 then the à51 now trying to get a a71 so can't be bad right

Verified Buyer

I can not write a review because I have not received it .also I ordered black .I have had difficulty trying to explain this ,you can't speak to a person every thing Is text .no one has contacted me except to give reviews or sell me something so overall. I have not had a good experience

Verified Buyer

Took a while to find my way around but that's normal when changing. I didn't really know how much I liked the difference until I went back to my old phone. Less than 24 hrs now I am loving the speed of everything and clarity . Brilliant camera. Love it

Verified Buyer

Well you got the wrong phone description, it was delivered on the wrong day, and I can't get it working yet with my old phone number... Jury is still out on the phone, but is clearly not great on much other than price.

Verified Buyer

Easy to use once you get used to the slight differences from the A5 I had previously. Some of the icons are a bit "childish" and the fingerprint sensor is a bit more "picky" than the A5, but these are minor niggles.

Verified Buyer

The galaxy A51 is a really lovely phone it's best phone I have ever had I love the finger print scanner and the music player has a good quality sound and the battery life is really goood

Verified Buyer

Well, I can say awesome screen and long lasting battery life, but have yet to give the camera a workout. Seems to be a good spec, good value phone well suited to my modest needs.

Verified Buyer

Verified Buyer
