    • The Nexus Asus tablet renders faster than the Optimus G but the Nexus doesn't render well a List view with disclosure and the items inside the List seems to disappear.
    • Both cases doesn't feel smooth and fast when scroll. I don't know why since the Nexus Asus has Chrome as the main browser.
