@YasinBajibhai Hi, resetting network settings sometimes fixes wireless connection problems. Try it from Settings / General administration / Reset / Reset network settings. Then you have to reconfigure Wi-Fi networks and pair Bluetooth devices. You don't lose personal data. Greetings.
@YasinBajibhai Regardless of what is recommended, you can do the following: Put the phone in safe mode for a few hours and see if the problem persists. In case the failure disappears in safe mode, uninstall the last installed applications one by one.
