Plz provide some more information. Is your mobile website coded with angular? Are you using ng-repeat or collection-repeat? If you´re not using collection repeat, you should take a look at: http://ionicframework.com/docs/api/directive/collectionRepeat/
Cheers!
I also experienced this with android especially in versions before 4.4. So your Galaxy S4 is 4.3 or before. In my opinion the current beta state of ionic is not the best solution for low android apps. Ionic rocks for iPhone only at the current state.
