Recently brought Karbonn Sparkle V running on 1.3 GHz quad core with latest android KitKat 4.4.4 as operating system. I has no built in file manager so I installed ES File Explorer Manager to access data on phone and SD card. But ES File Explorer Manager could read only SD card not internal storage. I tested different file managers but result was same they could read only SD card only. I also tried to connect my phone to PC there also I could see only SD card. Please help me to access internal storage.
