I have a new Samsung 6, with a weather widget that works, but not as user friendly / easy to read as my old Samsung 4 note, weather widget.
Accuweather states they only feed the info a third party does display and formatting. Enclosed is a pic of the display and format I am seeking, a widget or app, with these qualities, for easy to read and understand.
I know I rely heavily on my weather apps/widgets. I know you mentioned reaching out to Accuweather already. Have you tried any other Weather apps (ex: Weather Channel, Weather Bug, etc)? Also, we would recommend passing along your concerns to the phone's manufacturer (Samsung) as we are the phone's service provider (calls/texts/data).
