[Dany90210]

Have you all ever experienced with your oppo f9 phone setting. I just bought my new oppo f9. I been set/customize my phone but the setting keep coming back to the previous(standard) setting. So until now i cant set my phone not even save my friends number. The weird things is i can still download new apps.
