Scroll does not work on Android

1

Hi all!
I have next code

<ion-view>
<ion-content overflow-scroll="true" ng-controller="StoreCtrl">
    <ion-list>
        <ion-item ng-repeat="item in selectedPos.items">
            <img ng-src="{{item.img}}">
        </ion-item>
    </ion-list>
</ion-content>

But it does not scroll on my Android device. How can i fix this?
