Constant app crashes + google play error 960
Found this page while trying to solve the same problem on my Nexus 5. Here is the succinct answer that worked for me: You need root and to install an app called SD Maid (Play Store Link), run it's "CorpseFinder" function, remove the corpses, and reboot. Force closes and 960 errors stopped for me after doing this. I elaborate more here on this thread on AndroidForums.com. Hope this helps!
