iPhone 6 slow, freezes, unresponsive
My iPhone 6 is extremely slow/laggy and sometimes unresponsive.
This happens when going into an app such as Facebook (takes nearly 1minute to open up), going into 'settings' can sometimes take 15seconds where the settings page loads but the phone is unresponsive, safari hardly ever loads any pages- the url will change as if the page is loaded but it is just white.
Updated to the most recent OS; 8.1.3
Phone is only two days old.
Any help or suggestions would be appreciated. Thanks.
iPhone 6, iOS 8.1.3
