I need some serious help with my now nearly defunct GS7. I can't retain data for any apps other than the Chrome Browser which is still fully intact. Any app I make settings for never keeps them after exiting and opening the app again. For example,I open ES File Explorer and see the tutorial. Then I make my choice of what settings to use,and finish. I then closed ES File Explorer and a little bit later,I opened it again to find it displaying the tutorial a second time with all of my settings undone! Other apps I have will no longer open and all force close as a result,even after clearing their data. I am completely lost a knowing what to even do at this point. If there is an app that properly clears extra app data that is normally missed and other garbage files,please link me to it. If there is an app that can fix the corrupted conditions of my GS7,please link me to that as well.
