This is a really good and stable phone, wish I could have gotten it in a 64 GB configuration. Dual SIM feature works great, screen is great, very comfortable in the hand. Just one issue which Ive noticed with it which is why I gave it 4/5 stars instead of 5/5. There seems to have been a flash of the firmware done in order to unlock it as it does not allow you to use Samsung/android pay or turn on secret mode in Samsung internet. I get an error staying rooting detected and secret mood cant be used on rooted devices. I do not use this as my main phone so it doesnt bother me much, but if you plan to use those features on this phone beware.
1) Very good screen the AMOLED screen is the best screen I have seen a in this range.
2) Good battery backup. Even after gaming a bit during office having LTE and 3G backup all day, along with lots of browsing etc.
3)Audio quality is decent(through headphones)
4) camera is just awesome.
5) samsung pay was a huge bonus for me. No need to carry cards or your wallet, it works with and without NFC POS machines. I use it everyday.
