Did those troubleshooting steps include clearing the cache/data of both the Play Store and the Download Manager apps?
I need a fix for this problem. Did all the suggestions and still no good. Downloads are quick but the install takes forever.
Have you tried uninstalling play store update and updating again then clear data, force stop and try again.Tried wiping...no help..... another interesting thing is apps take a long time to uninstall also.
