The battery died on my Samsung Galaxy Note 2. I finally got it charged and turned back on. But when it turned on, I had lost most of my apps. Now when I try Ito download pretty much anything, I get the error code "-24" on Google Play Store. I cannot even download clean master. My phone is NOT rooted so that's not the problem. I have tried all of the suggestions, except for doing a reset (which I don't want to do), but nothing has worked. Can someone please help?
