    The same problem here. Overnight my phone decided to turn bluetooth and wifi off. I was not able to turn them back on exactly the same way as other users above mentioned. I have restarted/rebooted, took battery out, did a safe mode check, nothing changed. Backed up my files and made a factory reset. No fix from this either. On top of all to recover all settings I've backed up before, my phone requires WIFI which obviously I can not turn on... That's what I call a total screw-up.
    I am not comfortable with the idea to take my phone apart as not much video shows how to put it back together and with that for sure I would lose my warranty. Any ideas what else I should try before I trun my phone in to a shop?
    /Problem is the phone was bought in another country to where I am not able to return it as I have moved since, and there are not any main Samsung shops around in Andalusia nor in Gibraltar where I could easily turn, so I would prefer any home fixes before doing that/
    HELP!!!

    "When I switch my wi-fi on it goes on "turning on" but then brings an error and I can't do anything about it. I have done extensive results but everything doesn't work, I even did a hard reset on my device. what is the solution for this? I even tried connecting to a new VPN an nothing seems to work. Is this a hardware or firmware problem?"

    Personally, I think its a firmware problem, something to do with a dead driver, but, I don't seem to understand why resetting the phone doesn't make it work afresh.

    Same my problem........

    My wifi and bluetooth go a light green when i try switch on but nothing ever connects then t returns to grey. THis goes on for hours and hours.
    Ive done a factory reset and it maybe improved things for a day or so now the problem is back.
    Model Number - GT-I9500
    ANdroid Number 4.2.2
    Network - VODAFONE IN
    Please help me to correct this error. This is some seriously bad PR from Samsung we pay out our rear and two or three months later the phone has gone to crap and noone can help me at all.

    Welcome to the forum

    When you did the factory reset did you sync with Google when you set it back up? If so it likely installed the same app that was creating the problem before the reset. The only way to narrow it down is to use it without installing apps then install one at a time from the most necessary to the least until it starts being a problem again. I purchased my S4 when they first came out and have found one app that will mess up the battery but otherwise it;s as good as the day I bought it.

    Try charging it over 30%. My husband has an S4. He started having this issue yesterday so I've been on these forums a ton in the last 48 hours. He tried some hack from a video typed into the dialpad and then he yanked the battery out without shutting down the phone and his wifi was restored. Overnight his phone died and there was no connectivity again once he got it turned on again UNTIL it hit 30%. It's been fine ever since as long as the automatic power save from dipping too low doesn't engage.
