Using an Android is a great experience for me.it is a fully loaded os with their amazing apps.But it disappoints me little as it doesn't provide fairly 100% multitasking as i experience while browsing and downloading when i switched on other apps i lost my page , it shows only recent apps by pressing Home button long but not to worry about it their are many apps which can solve this issue.
