  13. Good day bro, I successfully flashed cm11 on my R7 but ever since, i've been able to install apps only on my SD card and it's as if the custom rom is now using my memory card like a phone internal storage. Pls, is it an error or is that how cyanogenMod works? Because my fear now is that d SD card is only 16gb and it's almost full already. I cannot even move any installed apps from the sd card to phone storage. Pls, give me a suitable idea. Thanks boss!
