I am using LAVA Iris 501 ICS 4.0.4 Android Phone for the last 3 months. It installs all the applications in External Micro SD Card which is removable. Now I have purchased another phone Karbonn A30 ICS 4.0.4. for want of Big Screen (5.9 Inch) to play games. I am very much annoyed because it is not installing any applications on the External Micro SD Card. The phone always says storage full. How LAVA Iris 501 is supporting installing of applications on the External Micro SD Card, so why doesn’t my Karbonn A30 not support it, when both of them run Android ICS 4.0.4?
