hello. iam thinking to buy xperia Z2 or samsung S5, so iam aware about sd restriction that kitkat offers,cos i dont want to be rooted, i would ask for a specific scenario: 1. l use firefox browser and i download an apk file,can i move that apk to sd card? or download directly to sd crd? 2. is there a file explorer that can to do that ? move from internal memory to sd card? tnx. i forgot to ask if the device supports OTG (usb stick) can i move files from internal memory to usb stick?
