My husband has a samsung galaxy beam. He downloads an app it downloads then when installing it reboots . Any one had this problem and fixed. Its only been doing it the last three four days. Thanks

Re: app wont install

Welcome to Android Central! Is he installing from Google Play Store? Does this happen with any app, or just one particular app?
