[Q] Can't turn wifi or bluetooth on

Hi so i've been searching and re-searching over and over to fin what is going on but i can't find a solution to my problem, turns out that mi wifi (and bluetooth) can't turn on, funny thing is, i have to reset several times in order to make them work but it will last just a few minutes, although i have notice that when i make it work and stay connected on a strong wifi signal sometimes it wont deactivate but not always this is getting frustating, another thing is that when i do a factory reset or install a new rom rather stock or cm or any variation it will work but just for a minutes as well.... any idea what it could cause this and how to fix it??

No service, stuck on airplane mode

Two weeks ago i wnet to a pool and i took pictures under the water wiht my Z3, at first it didnt have ayn problems but then it started to reboot constantly, then my desplay show diferent type of frames.
I thought it was xposed cause i used the workaround method and it reboot some times.
After a restore my phone went well and it appears everything works good. But i didnt have any signal. After a few hours of waiting i turn on airplane mode and then i turn it off my phone had signal and it appeared everything worked good. After two weeks, my phone had lost data i could navigate or connect to mobile data.
I thought it was for reception and laso because i install xposed again. I did a restore and suddenly i didnt have any singal. I tried everything restore, airplane mode... etc. The only thing that worries me is that when i try to call it says that i must turn off airplane mode before. I search a lot about this issue i found one similar thread in xperia support that it happened the same way i did. Also other has the same issue because he upgrade his phone to lollipop.
But thats not all, also it has happened to other android phones but no one has find any solution.
After a few hours of trying everyhting im going to take my z3 to sony on thursday .
If some has some similar and knows a way to repair this is the time to tell jeje.
Greetings

[Q] Anyone's phone disconnecting from wifi and freezing up for a few seconds?

I'm having this problem on my tmobile s6 where my phone screen will freeze randomly but it only happens anytime i lose connection to wifi. When the phone unfreezes, it always shows that I now connected to my wifi network. Am i the only one experiencing this. Im on xtrestolite rom (tmo version) , stock kernel
Did you ever find a solution to this?
My Verizon Galaxy s6 started doing this randomly 2 days ago. While looking at the wifi screen, it will toggle itself off and then back on, sometimes as much as every 20 seconds. If i'm in an app the whole phone hangs and becomes unresponsive for 10 seconds or so. Seems fine when it isn't actually connected to wifi.
I haven't updated or added apps recently. I tried a factory reset and it seemed fine, but when I put all my stuff back on the phone it started doing it again.

Nexus 5 WiFi Crashing Phone

Hi all. I have a weird issue that after Googling it doesn't seem anyone else has had.
The issue started earlier today, in the morning. I was using my phone on the WiFi and it was working phone, then my phone crashed, restarted itself.
I noticed it wasn't connected to the WiFi, went to the WiFi settings and where it usually says the list of networks it said "Turning on WiFi" and the slider at the top was greyed out so I couldn't turn it off.
I tried airplane mode and that didn't help. But the phone was working fine on my mobile data so restarted.
Now the weirder part starts. I basically have an issue where, if I turn on the WiFi, my phone crashes, or doesn't act like it's turning the WiFi on.
Even going Settings and then pressing on the WiFi option freezes the phone.
The problem started when I was still using 4.4.4 however since the problem developed I've used my mobile data to download the updates and now have 5.1.1 I think.
The problem persists even after updating to the most recent version and doing a factory restore. The phone is currently completely stock with nothing downloaded on to it. All I did is go through the first time setup for the device.
The WiFi currently is off, and the phone is working however it won't connect to my data, it has the signal bars and then an ! instead of a 4G icon.
If I try to turn the WiFi on it crashes the phone.
The phone is still under warranty so I plan on contacting LG on Monday however it's currently 3:34 AM on a Sunday so I have a day until I can call them and was hoping for a solution in that time.
Thanks in advance. I have the phone to hand so anything you want me to test I'm able to.
There is some information I didn't type as I don't know what is important was trying to avoid a wall of text so if you have any more questions I'll answer I best I can.
Thanks for reading, I hope you can help!
