Samsung Galaxy A51 is rated 4.3 out of 5 by 213.

Rated 2 out of 5 by Sophburrs from Slow, laggy and completely mis-sold. Had this phone since July and I near enough instantly regretted getting it. The only reason I did in the first place is because the sales woman (EE not CW) talked me into getting this instead of others I was looking at. Battery only just lasts one day and seems to be getting worse already Its! Its so slow with everything, freezes a lot also (even writing this is taking forever because of it lagging after every other word!). The main thing I look for in a phone is a good camera, my previous huwawei p20 pro was fantastic. The camera quality on the a51 is quite good inititially but it doesn't take a photo until seconds after you press the button so half the time I miss the shot, then as soon as you slightly zoom in the quality is awful! Safe to say I feel like I was totally mis-sold this phone, its frustrating and I honestly wish I could just swap it already!

Rated 2 out of 5 by Sambo1984 from Nice looking, great features, slow Sleek, full of features but painfully slow from the outset. Camera is cleaver but very slow to open or react. Phone doesn't run very fast considering it's processing power. Very disappointing. Will suit someone who isn't in a hurry. Overall not a bad phone but too slow for me hence the low stars.

Rated 3 out of 5 by Mark 500 from OK phone Not a bad phone there are worse ones about, but the fingerprint scanner is terrible. Shame because its really quite a decent phone , just remember its a middle of the road phone that's not that bad for the price.

Rated 1 out of 5 by Twinmama13 from Worst phone I've had in a while Thought I would move away from iPhone for something more affordable. Have ended up getting a refund for this and going back to apple! Battery life is shocking after only a month of use, doesn't last until end of day now. WiFi constantly has issues and you have to turn WiFi on and off to get it to work. Camera crashes all the time. It just doesn't seem to like apps at all, so slow and laggy. Really slow to respond in general so you end up wondering if you've actually tapped it and end up double tapping and ending up in a fight with the phone. Fingerprint sensor is HORRIFIC and hardly ever works. Camera is terrible in low light and even in normal daylight has awful focus issues unless you're right in front of it. People keep telling me my phone is switched off and calls go to voicemail when it is on and literally sat right next to me. No swipe feature to go back and forth on browsers so if you accidentally swipe back, which you will with this flipping thing, you lose your place completely and have to start again. Really wish I had listened to all the reviews before I bothered with this one!
