Galaxy A51 5G Prism Cube Black Android Smartphone, SIM Free Mobile Phone (UK Version)

It is a good phone but the optical fingerprint reader is not as good as other types of fingerprint readers. It can be pretty annoying sometimes especially if you put a screen protector on your phone. Update: if you do not use a screen protector, the finger print works perfectly. Generally it is a very good phone.

face recognition is not the best and the fingers read if get better the phone would same as s20

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?).

Finger print recognition works great built into the screen the battery is fantastic will last all day it's comes with a fast charger nfc works as it should for a medium end phone it's well worth the money

I have been using Samsung phones (S series) for more than 10 yrs and it always worked but this is a really bad product which broke down in about 12 months of use. I have moved to iPhone now...not coming back again to Android/Samsung.
