I have a A81 MICROMAX Android phone version 2.3.5. it has the internal memory of 100 MB and 5 GB external memory.When i download any application via google play or try to install via external downloaded packages it never accepts and repeatedly saying you have low memory space. I have memory card as my default location. What am i doing wrong? Example application is Temple run 1 or 2 it is not accepted by the phone
