Phone turns off when I switch on Wi-Fi?

[ClairesLove]

So this is a pretty serious problem, for the last few days (Potentially since I updated to lollipop at the weekend.) My phone restarts as soon as I turn on the wifi, and after restarting stays on for maybe 10 seconds before restarting again. I have those 10 seconds to turn off wifi otherwise it continues to do it. (Potentially indefinitely, though I haven't had that much patience.)

I do have unlimited data, which is an absolute blessing in this situation, but I could be stuck in the mud here. Has anyone else heard of an issue like this, or does anyone have any idea what might be wrong, and how to fix it?

Welcome to Android Central

Try a Cache Partition wipe, good practice after a software update. If that doesn't fix it, get back to us. There are other things that we could suggest.

(Excuse me if this is obvious to you, but be careful not to Factory Reset by mistake....all personal data not backed up would be wiped from the phone. Cache Partition wiping does not cause a loss of personal data.)

Cool, awesome suggestion, I don't think it's changed anything though.

Round 2?

It may be worth trying Safe Mode, which will determine whether the problem is being caused by a third-party app. If it doesn't occur in Safe Mode, you'll have to identify the app responsible, and uninstall. If Safe Mode makes no difference, it's not that.

Also, an SD card, if you are using one, can cause trouble if corrupt...you could test that by unmounting and removing.

If still no go, get back to us.

No luck. It's still doing it. SD out, and checked in safe mode too. Might it be something wrong with the hardware, as my brother thinks?

Bonus: the doorbell went, and I forgot about my phone, and came back to it 10 minutes later, and it's still turning on and off every 15secs or so, so now I know it's not something that just sorts itself out.

This is a long shot but it won't hurt trying

I remember reading that some people had problems with the Smart Mode and Smart Switch. Take a look in the settings and switch them off just on case.

I'm not sure what you mean by smart mode/smart switch. I doubt you mean the content transfer app that samsung uses, and I also don't have it installed.

Do you mean the network switch option? In which case, I've actually tried turning on wifi with that toggled on and off, and it seems to make no difference. It didn't hurt to try though, you're right.

 

[Javier P]

My idea was to switch off any possible WiFi optimiser in your phone. There's the stock one in your settings - WiFi - advanced. Some Samsung phones come with an special feature and even some carriers implement a different one. Most of them are called Smart something and I've read people having problems with all of them.

 

[ClairesLove]

Yeah, unfortunately I'm not sure that one makes a difference. Should I just be taking it down to a shop?

 

[Javier P]

Before taking it to the shop make sure you have a backup of everything you want to keep. Most likely they will try a factory reset. Being directly related to the WiFi they'll first assume that is a software problem.

Remove the battery for a minute or so and see if that helps. Check there's not any bulge in it. The best way to do that is to put it on a flat surface and spin it. Try with a spare one if you have any.

I too have the same problem bro and still havent found any solution .

Why my phone shuts down when i switch on wifi.

 

[Charis Kimbeki]

Same here!! It works fine in safe mode but when I switch out of safe mode it shuts down when I switch on my WiFi. I don't want to continue on rebooting my phone like every week or month, you know?

Welcome to Android Central! If it doesn't happen in Safe Mode, then something you installed is causing the problem. You may have to uninstall apps one by one until the problem goes away.

So I was having the same issue with my Moto G Stylus 2022. Eventually I used the long press off method (not a reset), and when it came back on the WiFi was magically connected. No problems. I was a fool and disconnected the WiFi when it got slow and now I'm having the same issue again. When I got it to connect it would jump to other WiFi's fine without the restart loop. I don't know what the problem is or why it started, but just thought I'd add to a old thread lol.

 

[Grayfox]

So my above method worked again (turned off phone data, or turned on airplane mode. went to WiFi to connect it, when the phone restarts, hold the on button until it turns off. Then press the on button to restart. Once it starts connect to WiFi. If it restarts again, just long press the on button again. If not, then turn off airplane mode, or turn your network data back on and it should be fine).
