After updating to Android 4.1 smartphone is useless. The mobile phone is absolutely inert. After each exit an app you have to ca one minute many times even longer wait reappear until the icons screen. Partial calls can no longer accept it is really awful and impudence of LG. A tip for those who can not give it back. Habs iergendwann no longer endured and rooted phone and a custom ROM flashed (CanyogenMod) since it works properly
