I purchased and installed ROM Toolbox Pro on my android phone in order to use it to change the location of installations, but it didn't work. Upon changing it I tried to install a game, and, since I didn't have enough internal storage, it didn't work. I went back into RTP to see if the setting had been changed and it had so I changed it back. I then proceeded to look at the setting again, without closing the app, and it had been changed back to "auto". How can I fix this?
