Wi-Fi and Bluetooth icons are blacked and crossed out
When I got home my phone rebooted on its own. After that, I ran into the problem that the wifi and bluetooth icons in the control center are darkened and crossed out. If you try to turn on the bluetooth in the control center, for example, it will turn blue for a while and then turn off. If you go through the settings, then there will be an endless download and you can not turn it on.
