I've been experiencing strangeness with my phone: when I charge my phone WiFi doesnt work, but if I don't charge my phone WiFi works perfectly fine.
The signal of the WiFi is full bar when I use it while charging.
I tried force rebooting my phone, shutting down my phones many times.
I can't use my SIM card because it said your SIM card is not properly placed but I placed it properly.
The device is a Pocophone F1 with Android 9.
