Has anyone updated to marshmallow? I recently did and noticed several features I often used gone...first the power saving mode is changed and does not turn your screen grey anymore to save battery life. Also I often used power saving mode when I wanted to quickly charge my phone (this would charge the phone much faster than not having it on)and this feature is also gone! Another feature gone is being able to quickly preview a text in the notifications bar without going to the text..if anyone can help please lmk
