How do I stop Play Store from randomly opening when I'm in other apps? Play Store is randomly opening when I'm in another app. It is simply showing me an app it thinks I would like, even though I haven't initiated any action on Play Store. I'm running Jelly Bean on a Motorola Razr Maxx.
Are you clicking on ads inside apps? Because they would pop-up Play Store immediately. Remove all those apps which pops-up ads very frequently. If no - try signing out of the Play Store and stop it forcibly using App Manager. Then start it and login again. Post what happened.
