I updated my LG G6 to Oreo. I have gotten used to the quirks and learned to live with the inadequacies. However, I have yet to dicover how to add a blank screen. I have resolved the issue by downloading an app "Bank Widget". In spite of the success of this little app, I would still like to know if it is possible to add a blank screen. Can one of you knowledgeable, smart techies help a grandma out?
