Nokia has come up with pure android os with this model. Has a 5 inch display with good colour reproduction. Touch sensitivity isn't that great. It suffers from multiple touching, which makes difficult to play games. It has 8MP front and rear camera. Front cam is quite good, rear isn't that great. It doesn't come with fingerprint or facelock. It has 16 GB of rom and 2GB of rom. Offers smooth run on a normal usage but cannot stand on heavy usage. The speaker quality is not bad. The best thing in this smartphone is its battery life. It has a 2650 mah. But lasts more than a day in normal usage and 6+ hrs in heavy usage. There are many drawbacks in this phone like no fingerprint or facelock, suffers from multitouch, low processor, not many gestures, poor camera quality etc.
It's better to go for nokia 6 or other models instead of Nokia 3 as it was not upto the mark
