Why does System update always fail?

Do I have to update the phone to the latest version?

Why can I not receive the system update for a long time?

What should I do if I cannot finish downloading the system update?

I cannot check for the new version. What should I do?

Why is my device’s Android security patch not latest?

It always shows “verification failed” when I download & install the update. What should I do?
