This phone is a great option when it comes to those looking for pretty basic feature sets, and nothing too fancy. The phone retails with Android Nougat out of the box, has a pretty standard 5.3 inch HD screen, 2 GB of RAM and 32 GB internal storage.
Battery power is decent, with 2880 mAh capacity and decent life. The display is of the IPS LCD kind, which is on par with many big brands and phones. Straight from the box, the K30s firmware can be upgraded to a newer version.
So, the bottomline would be that the K30 is a great option for the entry level price range. We would suggest you to keep digging, however, before you make the decision. It is possible that you come across better phones in a similar price range, such as those made by Chinese smartphone manufacturer Xiaomi.
