Most likely it's caused by 3rd party app. You need to find out which app it is and uninstall it.

Haha. Then I guess we should be considered as lucky for the delay update on Note 8? I mean..the feeling of having Oreo update before CNY indeed is good~ But if it comes with bugs then really .

Let's wait for Samsung to iron out all the bugs first, the Oreo will come to us eventually. As a proverb said: "Good thing comes to those who wait."

So let's celebrate this CNY first without worrying the arrival of Oreo.

Although it's still early, let me say Gong Xi Fa Cai to you bro, and other Note 8 comrades as well! Huat ah!
