My Xiaomi Mi 10i was glitching and I sent it for repair, but unfortunately, after repair, the WiFi doesn't want to turn on (it just turns off from the settings toggle and doesn't turn on from notifications).
After a few days, it automatically fixed itself, but then I had it factory reinstalled (because I thought it would have spyware from the repair shop) and now it doesn't work anymore.
Bluetooth and cellular data have no problem in working.
I wish someone could help me with this.
