Please what is the solution for that.
As you are not seeing any error, it is really hard to provide you a solution. 
but as part of troubleshooting. 

just go to Settings > App > Play Store and clear cache and clear Data. 

If that does not work, you can download latest Google Play Store (Google it for APK) and copy it on your device and manually install it again. 

Even if that does not work, then last resort is to do a factory reset. 

Lastly, you recently bought your phone and so you have warranty, let the service center guys take the headache. 
(I am assuming, you are not rooted).
