Intex Technologies — Storage problem

Address:

Indore, Madhya Pradesh

Sir,
I have an intex smart phone . Model is intex_aqua_power_V09_indian_SER. In
my phone, whenever i download any app or games from playstore it get stored
in internal memory then i have to manually move the apps or games to sd
card. But since the internal memory is small some apps are failed to get
installed n shows the error of insufficient storage space. I have 4 gb sd
card bt still the apps are not stored in sd card directly . Even my phone
storage is also empty, nothing get stored in that also. So please solve my
queries asap.
Thankyou.
