When I was purchased this phone the quality was not so good that I can take a photo of any thing. And the camera quality should improve.
The ram was not so good the ram should increase than it will function properly.
The display size should increase and colour is fine .
The dual sim facility also provided as user can take advantage of two sims.
The internal memory is also low as compare to other smart phones atleast 4gb internal should increase.
The phone should updated with new version of android.
