Samsung’s claims fall flat for the actual real-life performance. You’ll realize the performance enhancement features aren’t luxury but more of a necessity to mask the inadequate hardware. The truth is that the Spreadtrum Chipset just does not have enough power. This shows in the phone’s performance, which often stutters in several places in the UI.
Gaming is also a no-go, unless you are into light 2D gaming and even then you might see an odd stutter here and there.
Samsung also had to employ some aggressive app management to make up for the limited 1.5GB RAM. But there is nothing they could do make up for the lack of storage, of which only about 1.4GB is available to the user. You then have a measly amount of storage left for your own apps. Even though there is microSD support and the phone runs on Marshmallow, you cannot format a memory card as internal storage to extend the storage space, so you really are struk with the 1.4GB for your apps, which runs out faster than you can spell out your full name .
Cons:
Speaker is not loud.
No noise cancellation.
No auto brightness.
No compass/magnetometer sensor.
Build quality is very poor.
Internal storage is not enough.
