Thank you for responding sir..I encountered the same problem before so I the first thought I had was perhaps it's because I installed too many apps, some I barely even used. It turns out it I was right when I restore factory reset my phone. By the way I'm also using an Asus m1 pro phone. If I were you I would try doing the same thing as I did, hard resetting your phone. Only if you have no other options left. Hope this would help you.
