I am facing some weird problems with my Oppo Find X9 Pro. Help me out please
​
First Problem: There are some apps that only work on mobile data, and some apps that only work on Wi-Fi. For example, when I am at home and want to use certain apps over Wi-Fi like listening to music or using other applications some of online shopping apps they just don't work on Wi-Fi at all. I specially have to switch to mobile data to get them running. I have no idea why this is happening. (I use Apple Music btw)
Second Problem: When I install an app, the installation process takes an unusually long time occasionally, whereas other times it happens instantly. I don't know why this behavior is so inconsistent.
Third Problem: When I switch to Night Mode or Macro Mode in the camera app, it sometimes automatically toggles off or fails to stay in that mode. I can't figure out what to do. I have already tried restarting the phone and checked everything, but nothing seems to work.
Fourth Problem: The data transfer is slow compared to my previous device (Samsung s24 ultra) No matter if it's a 3.2 gen pendrive, HDD, or SSD transfer speed is comparatively slow
