Cuz it crashes and it use mobile substrate that reduce my battery life.Can I ask why you don't want to use Snappy?
Oh REALLY?You could just use Activator to set a gesture to launch the camera app. That would be the best option for your battery.
right, but then the camera app still make long photos. With snappy it takes 1 sec.What I mean is you wouldn't install Snappy at all?just use Activator to launch the native camera app. Then you can stop worrying about mobile substrate.
