Rated 1 out of 5 by from Speaker and Camera faulty I got my A31 on 15 June 20 and I was very excited as I needed a new phone urgently. The phone worked fine for the first two days however between yesterday and today my phone started acting up, my earphone volume was low, voice call volume is low. The fast charge is not a fast charge, today it took the phone about 4 hours to get fully charged despite the phone saying its on fast charge. My camera is not consistent it decides for itself when it will work. The finger print sensor does not work at all. I'm really disappointed because I was so excited Im a loyal Samsung member but I was very disheartened to find out that Samsung still has not improved on the phone battery and charging, im so disappointed that I'm facing such problems so early in my journey with this phone

Rated 3 out of 5 by from Irritating bugs Two days with the phone and I am really annoyed. Camera app stops working, which affects the torch and facial recognition feature. Also seems to freeze the pull down menu options. I press any of them and nothing happens. They don't activate or deactivate. Have to keep restarting the phone. I loved my Samsung J7 and A3. They both still work really well after 5 years. So I am disappointed after all the great reviews the A31 has received. I would recommend it to a friend based on the features and if the bugs are sorted QUICKLY.

Rated 3 out of 5 by from Great features and unquestionable One UI❤ I bought this device on January 4 or 6. It used to lag while setting it up and it still lags but not that much but STILL. It heats up alot and whenever i connect to wifi after keeping it off for 1 day although it connects to the wifi immediately but i start getting notifications after at least 3 mins and it lags alot there also. It lags while opencamera or in camera app. Snapchat clone and orignal both also lag. Its ok if It doesn't have have any screen recorder but i hate when this phone works lagy while recording from 3rd party app. Although it got smooth on android 11 but still it needs much more improvement. I hope you will see forward on my feedback

Rated 3 out of 5 by from Not up to the job! I've had the phone just over a month. Before this I had a galaxy 5 for about 3 years but it was tired. This phone is lovely. Visually perfect and camera and picture excellent. Drawback...... software maybe. Too many updates necessary and migration was very incomplete. I'm really disappointed with this phone. Wanted to smash it already and that's not in my nature. Frustrating! Language and predictive is terrible. I wish I didn't have to have a phone at all because of this phone!!!
