I've had my S5 for a few weeks now and have had this issue all along. The Weather Widget on the first home page keeps disappearing. I searched back and found other with this problem but the answers focused on how to get it back and not why it disappears in the first place. I know how to get it back. I want to stop it from disappearing in the first place.
Seems that today, if I add it back, lock the screen, and open back up again, it is gone.
