App's not installing after download complete? I'm facing a problem while downloading apps.I have recently rooted my android which is Samsung galaxy tab 3 smt210r.But after a couple of days i am facing a problem that is when i download an app it does not install.it just disappears from the status bar after reaching 100%

I tried restarting my android,unistalling updates of google play,clearing cache of download manager,google play.but none of them seem to have solve the problem.

please help me as fast as you can.i can not even update any single app.
Try to delete package folder of downloaded app manually, if exist from phone storage > Android > data 

Reboot device again and download app again.

Hope it helps.
