    I have a Sprint Galaxy S4 that I've had for about 2 years. About a month ago the WiFi and Bluetooth stopped working. I'm most concerned about WiFi. What happens is I turn the WiFi switch to on and it stays grayed out and then after about 2 seconds it turns back off again. Won't even enable. I've tried restarting the phone, taking the battery out, hard resetting the phone, changing the settings, and replacing the WiFi antenna. Nothing has worked. Can anyone help me? I'm so frustrated.

    Update: I removed sim card and put it back in and now the WiFi will turn on and green for about 5 seconds and then turn off for 5 seconds and then on again etc., forever. Sigh.

    It's probably an issue with the motherboard itself. You can try to buy one second hand and swap the motherboard.

    Unfortunately, not worth replacing. Thank you though.
