I have tried Galaxy A5 and now I have Galaxy A3. Both phone are awesome very fast and smooth. In the review of A3 on YouTube and even the description on the box it’s not mentioned that A3 is fast charging I get impressed coz it’s changing very fast like an A5. But the simcard slot 2 is optional to memory card. As I mentioned above phone is very fast and smooth. Camera back and front is GOOD but not like the high end Samsung camera that everything has. OTG IS WORKING very very fast I transfered big data movies wow it moved to my phone from flash memory very very fast. Screen clarity is awesome battery is perfect my overall rate for this phone is 9. One more thing the reason why I switched from A5 to A3 because I’m a sport guy I always do sports that’s why I always try to cary a smaller size phone but it blown me out when I saw in the settings that keyboard size can expand it. I though having a small phone also has a small keyboard size but I impressed again because I can expand the size of my keyboard. I am very happy with this phone
