Is it a bug on stock from? I had even factory reset but still the same. Trying to use 3rd party launcher such as Nova, Action, Google now - all these failed to have widgets displayed n always settings force close!! So now no choice but to use Lenovo launcher
Only significant weakness of this phone is very slow shutter speed of camera. Hands must be steady to take good shots. Camera shots not class leading but decent enough I guess for most users.
