Hello, my problem is kwgt widget on y homescreen goes blank frequently as shown below. I have to tap on the widget and click save in kwgt then only it will show up again. How do i solve this?

See if you don't have Kwgt in Battery save mode in your phone, if yes, whitelist the app from here to prevent your phone kill Kwgt services, and allow it to run in background.
