Quick pick seems to be like very friendly and it is an easy way to handle photo gallery.But frequent updates of this application is showing trouble making in devices.The company immediately started uploading users’ data to their own servers, as evidenced by one Google Plus user who found a raft of new DNS requests that were attributable to the app

This app was down rated after updates due to over pumping of adware and blotware,and it endlessly nags you to download additional apps via non-disable-able notification bar pop-ups
