My son has a Samsung Galaxy 4 tablet with 8 gb of internal memory. Unfortunately, almost half of that is taken up by the operating system. He has quite a few games downloaded and I have a 4 gb sd card in his tablet. I got the bright idea to try and make more room by moving the games to the sd card. It looks like all it did was move the memory of the games to the card but not the whole game. is there a way to reverse the process and get the memory of the games back on to the device? I am not able to install any new apps on there because of the lack of room. Please let me know if you understand my question and have any suggestions. Thank you.
