Oppo F1f problems in WiFi,hotspot,Gps

Hi… In my oppo F1f I can’t use WiFi, hotspot and GPS. Could someone fix it and release updated package… Another suggestion if you could add direct phone call feature from mob. No.

you just need to install f1f spectrum project, then install /e/ without wiping anything.
I’m confused as to why that’s the case, but it worked for me,
sorry my English is bad
