My Android phone's memory is 64 GB.the available memory is 8 GB. the Disney infinity and Modern warfare 5 may take up 5-6 GB on my phone. When i download them, the phone indicates "insufficient memory". In order to successfully download and install these game apps on my Android phone, I intentionally deleted some videos and useless apps from Android , I download again , the same problem appears again. I don't know, I'm struggling, I've deleted some data and why is there still not enough memory?
