Samsung Galaxy A51 is rated 4.2 out of 5 by 218.
Rated 1 out of 5 by from Love the phone but now cannot hear phone calls Love the phone, but 8 months later discovered that I can no longer take phone calls unless put on loud speaker. (apparently this is a fault with this model, if you check online) Tried all the tests and my only option now is to factory reset before I most likely have to return to be fixed. Concerned as I need my phone to work from home. Starting to not like my decision to spend this amount of money on a new phone. Would normally recommend this phone as up until now I loved this phone. But 8 months down the line to have this fault when I hardly use the phone to make or take phone calls, is ridiculous.

Rated 1 out of 5 by from It drives me crazy I bought this at Christmas already had to swap it once still has the same problem,listening to a video suddenly the sound goes off ,after a little research I found the phone switched the audio to the jack plug so you have to reboot until it comes back. And bixby is a nightmare I don't want it I don't use it but its part of the system and can't be deleted or even switched off. If I could I would get my money back I have talked to other A51 owners and guess what it happens to them aswell so come on samsung you know the phones faulty offer us a refund on a very dodgy phone.

Rated 2 out of 5 by from Meh If you want a CHEAP and somewhat cheerful phone then this is the one for you. Other than that do not buy this phone! It was great at first couldn't fault the phone but after a while it started overheating apps started freezing, you open stuff and it crashes to a close straight away. The phone is simplistic to use, camera quality is good and the screen size is good but thats about it. A phone suitable for a young adult/teenager
