Hi I have recently bought Samsung Galaxy Tab 4 7inch with 8 GB internal memory and 4 gb user available. I am using and 16GB external SD card. I copied game cache into external sd card Android/obb folder and installed the game but the game cache is not recognized. But if i copy the same into internal storage Android/obb its working fine. Is there any way to fix this with out rooting the phone. As the user available internal memory is very low i can not install many games.
