Hello People, please I have a situation. My iPhone 5C is no longer connecting with Bluetooth , Wifi, Hotspot etc. I usually don't get to use the features but worried over it. Is there resolutions to these problems. What can I do in this case please. Kindly advice. Am scared of flashing the phone is that it doesn't go off completely . I want the Engineer in the house to please say something about this. Thank you.
