Setting wont open

[AC Question]

When I open my settings a white screen appeared and it said "Update now" I have done everything possible like rebooting. I have waited for an update to appear and it came 2 weeks later. Of course I updated but when it was finished the same thing happened with the message saying that I need to update... Please help men. Also my tablet is Lenovo
