Rated 4 out of 5 by from Does it's basics Forget about the negative reviews of this phone, those didn't even bother to read the specs. Of course there's no NFC!!! But I find a little pricey for what it can do as compare to other phones, a sweet spot would be $199, not $349 RRP. Anyways I am reviewing based of a good priced I got and this phone does its basics. Just beware of gaming, this phone does lag and delay, 6GB RAM ? i think not so for gaming.

Rated 1 out of 5 by from No NFC I accidentally left my wallet at home. I needed fuel on the way home from work and had to borrow money from a work colleague as I found out this phone does not have nfc. I am extremely disappointed as I thought this was a standard feature. I have had 5 Samsung phones and this will definitely be the last. DO NOT BUY THIS PHONE!

Rated 2 out of 5 by from Complete Let Down, So Angry As a "Galaxy kind of woman", I purchased the A21s (2021) between 2 & 3 months ago to unfortunately upgrade from my awesome S8+ edge. (After lots of good use, finally overheated due to me over working it & froze). A much smaller budget was available for me and after much reading & thought, the A21s was in budget and had really good reviews everywhere. Never should I have wasted the only money I had on this. Worst phone I've ever had ... its been nothing but problem after problem, but the clincher came when I finally (after 2 weeks) started to set all my digital wallet & ID stuff. NO NFC ... brand new Samsung Galaxy, Worldwide Covid, 2021 ... ummmmm contactless shopping etc?!?!?!!!! Cashless society everywhere we look and are slowly being forced into everything digital and contactless, yet my favourite Samsung can't give itself the basic respect of NFC being a basic standard. Yep, I'm ropeable Samsung. I'm still gobsmacked!!!!!!!

Went to return it and now have to wait for the phone to be repaired so with out a phone. should at least get some sort of credit or compensation for the integrity loss and de-rated ingress protection from the repair.
