Just bought unit last dec 23,2020. Less than a month some names listed in my messenger were erased last night. No one played w my cel the whole night. What could be the reason. Secondly if i look at my fb the arrow which would turn to original takes few seconds. I have to bring the unit to service center. Im disappointed.

After one day Samsung Galaxy A21s suddenly shut down, I had to hardware reset it and my fingerprint did not always work, kept saying no match.
I broke my galaxy note 10 and got the a21s just as a stand in phone, however I am considering just keeping this 1. I miss my spen etc but battery life on the a21s is good enough gets over a day which is great. I did miss my amoled screen at first but honestly I am starting to prefer this screen plus it's probably why the battery lasts longer and no screen burn. All in all for the cheap price I will consider spending alot less in the future. [...]
Thanks for telling me about my phone. It really does work with games like Asphalt 9 but there is lag. The camera is great. It's the first phone I've had with quad-cams. Battery, for me, charges fast. Overall, the phones really great for its price.
i have found a major problem with my new samsung a21s witch is that i cant move apps from phone memory to sd card, i have activated the developers mode and from there the force allow apps on external and still no use, i have also tried to format sd card as extended internal storage but there was only the normal format option also no use. ps. i live in germany thanks
honestly, i wouldn't mind the TFT screen if the screen resolution is 300+ ppi. below 300 is too low and this is a 6.5 inch display phone. i'm using a 5.5 inch display phone rn with 200-ish ppi and i can see how unclear the screen is sometimes
[...] Ive been using my iPhone 6S since 2015 and the battery life is cactus. This A21s phone now updated runs a lot smoother. The colours and photo video quality is duller than the iphonr but its a compromise for the battery life
This is exactly my phone and it is also in blue color. [...]
This is amazing I have used it for 2 months now and it's really good. The camera is good especially for a cheap phone and if you get it on sale. The only let down to me is the screen but it's still an amazing gone, fast reliable and easy to use and lots of settings can be turned on to optimise its use, battery life is good and my phone charges actually quite fast
A big upgrade for me and the phone had excellent battery life and quick charging. The downside is its as heavy as a brick and the main feature i.e. using as a phone is very poor in both the speaker and microphone compared to any phone I have ever had - why??
I have the phone for 1 month and i am not that happy my pubg crashes and other games audio glitches out but otherwise good phone
My 2nd phone ever using it for the past 5 years my og phone got me through gaming, so much the oh
[...] now iam allready upgrade to A54 after 4 years with this phone.
Commenting from the future lol I am still using this phone since November 2020 and it works very well
I got this phone 2 years ago and yeah it is sometimes laggy when I try to record a game and that's annoying but in a few months I'm gonna get a much better phone.

[...] Excellent battery life. [...] Excellent phone for it's price.
Note that this phone doesn't have full blown OneUi. It's a knee-capped "upgrade". I would literally swap it for an A20
[...] But i got my friends to switch to android. [...]
