title: ionic - Install upgrade 1.2.1 "amsterdam"
body: <p>I have got big issue to make my app working smoothly on android compare to iOS (samsung GNII 4.4.2 and S3 4.3). it seems I am not the only one to point it out. <strong>Main issue is the laggy scroll by default on android.</strong></p>
  
  <p>So I decided to upgrade to ionic 1.2.1 "amsterdam" to try resolving scroll issues and avoid to whrite down overflow-scroll="true" into each 
  
  <p>To upgrade to ionic 1.2.1 "amsterdam" I merely copied/pasted the content of the <a href="https://github.com/driftyco/ionic/releases/tag/v1.2.1" rel="nofollow">zip file</a> provided on ionic blog onto my project files. But I noticed that does not work : I do not have the native scroll by default on apk even if many files have been updated (I check <a href="https://github.com/driftyco/ionic/commit/11946ef" rel="nofollow">these lines</a> for example and it s OK).</p>
  
  <p><strong>So, where is my mistake please ?</strong> I would like to test the last upgrades to check if ionic is able to make my app working well on android.</p>
  
  <p>Thank you all</p>
