Samsung Galaxy A5 (2016) SM-A510F 16GB 4G Black - smartphones (Single SIM, Android, NanoSIM, GSM, HSPA, UMTS, LTE) – Poland

I bought the Samsung A51 from Amazon and it’s been a solid mid-range phone. The screen is bright and clear, battery life lasts all day, and performance is smooth for everyday use. The camera is decent in good lighting. Overall, great value for money with reliable features.

This is a great phone at a reasonable price. It looks new and was sealed and contained the headphones, charger cable and official charger and the mobile phone. The screen quality is good as new. the connectivity is good with with wifi and mobile data and seems to be durable so far and a good replacement of a previous mobile of the same make that I had before and it has the features that you need in a smart phone.

Purchased direct from Amazon, not 3rd party, for £235. Good value at that price. Replacing an A5 which was becoming too slow to be usable (built-in obsolescence?), A51 seems fine. Allowed it to update to Android 11. Samsung Smart Switch makes setting it up easy. Only drawback so far is the new optical thumbprint reader, which is pretty rubbish: even recording a fingerprint is difficult, it'll keep complaining that you're not covering the whole sensor, and my fingertips aren't small. Once recorded, fingerprint unlocking is hit-and miss at best. Add a screen protector and forget it completely; some people recommend re-recording the fingerprints once the screen protector is fitted but it's even worse. If you're happy with pattern, pin or face unlock, you'll be fine. But it's a step back from the A5, which had none of these problems (maybe it just wasn't very secure?).

Really pleased with this. It works well and has a good camera. It was certainly good value for money.

This phone is a replacement for an old and trusted Motorola. As I didn't want to buy Chinese I chose a Samsung phone....made in Vietnam, not South Korea as I expected! The fingerprint reader works but is slow compared with my Motorola. I may try face recognition instead. Battery life for my type of usage is fine, well over a day. I don't play games though. The camera system takes getting used to....all those lenses! Macro is really good, but regular snaps are hardly spectacular. I've yet to try low-light and night shots. I must work at it. Transferring apps and data wirelessly worked fine. Screen size and clarity is good. I've tweaked the keyboard to help ease typing...I'm a senior! Basically I like it! It's now May 2021. I've got used to the phone but still find the fingerprint recognition poor, also face recognition. I often have to enter my password as a last resort. Most frustrating. There was a software update a few months ago which I hoped might sort the issue, but no. The camera does work well now I've had chance to experiment. Sound and video quality are fine for me. WhatsApp calls are great fun. My wife and I enjoy catching up with family events. We are able to cast picture and sound to our TV via a Roku stick. The phone screen is very easy to keep clean, is super-sensitive and, so far, resistant to scratches. I have no extra screen protection applied but have bought a rather ugly but very tough case which, so far, has kept the phone free from dings or nicks. All in all, I'm very pleased with the phone and recommend it as good value for money.

All seemed ok with this phone at first other than not holding it charge for longer than 9 hours. Then the headphones i order with it didnt work well. I assume the headphones werent not the most compatible option and the charge might be down to it being a cheaper phone than purchasing direct form samsung. I noticed that if I was charging the phone I cannot read a text message etc because the phone would freeze or glitch. Then yesterday the phone suddenly cannot be charged. I thought it was the charger but have tried 3 others and nothing will charge the phone. I have tried to resolve it through the various avenues on Amazon but im being passed from pillar to post. Im devastated. I received an amazon voucher for 20 years service in my work and used it for this phone. What a waste.

This was a notable and affordable upgrade for me from my Samsung J3 (which was constantly giving memory full warnings and not saving things to the SD card). The A51 is a very fast, responsive and great phone to use. Moving stuff from my old phone to the A51 was relatively straight forward with the Smart Switch app. I've found the significantly extra inbuilt storage of the A51 to be great, though once I'd transferred the 16gb of the J3 data across the A51 had already used nearly 40gb of storage; this must have been due to the in built stuff and functionality of the A51. Thankfully the mico SD card slot works well and I've been able to load the music from my computer to the SD card on the phone via a usb cable. The A51 is very quick in loading apps and data and whilst it is a new concept for me I really like the biometrics finger scan. This makes it a lot easier to unlock the phone and log in to password secure apps without having to constantly type in or remember passwords. From a personal preference point of view, the phone is a little bigger than what I'm used to or comfortable with. It has already fallen out of my pocket. This was a compromise I knew I was making since I saw the dimensions of the phone on Amazon before I bought. However when it comes to the extra storage space, memory power and price point this was by far the best value Samsung phone for my needs. I am currently a very happy owner of a Galaxy A51!

2026 update: I've had this phone for 5yrs, daily use and it's still going strong. On battery saver it lasts 2-3 days. Biometrics are sound. Love it! Excellent phone. Looks slick and feels premium. Great battery life, fast charging (1.5hrs), clean display, lots of storage, top camera - even free headphones. I consciously avoided the flagship Samsung 'S' series - my work phone is an s8 and the curved screen is v frustrating (too many mis-touches), fingerprint reader is pants and the phone way too slippery to hold. The A51 is larger but ironically much more comfortable to hold. Also proper headphone jack - not all of us are interested in wireless buds. In all much better phone than the s10 and tonnes better value than the s20 for almost the same spec. Only niggle is the two stage phone start-up protocol which I guess is a security feature but feels a bit overboard.
