When wifi is turned on the phone freezes

Hello,
I have a problem with my Samsung Galaxy Note 2. The android version is 4.1.2
The problem i got is that when i turn on the WiFi, the phone will freeze, is unusable until i do a battery pull. after a restart i have to quickly go into the phone and turn off the WiFi or else the same thing will happen...
I tried to reset to factory settings, and to disable wifi safe mode.
Any idea?

No idea...

Do you have any media server on your network? Try to disable it or block your note Mac address from accessing it.
In my case synology dlna server caused gallery freezes - only gallery...
Is it happening on all wifi networks?

[Q] Z1C sends mobile data by itself

Hello all,
This is my first post here, so welcome everyone
I have following problem with my Xperia Z1C: It sends mobile data by it self while it is connected to WiFi and mobile data are switched off. Few times per hour I can see in my billing few connections (1kB, 10kB and 0kB) and system built in data moniotor does not show anything. I have the same set of application on Xperia M2 and it is fine. I saw today that data transmition follows the sign of GPS localization. I have sent the device to service and they replaced it but problem still does exist. Each time I try to refuse any data comunication with Google, but I bought smartphone to use internet and maps and apps.
The only solution is to delet APN config file but each time I want to use Internet I have to create new APN.
I guess that there is some problem in system and one of the apps receives permition to send mobile data while it is switched off. I tried NoRootFireWall etc without success.
Could you help me guys?

Did you agree that your GPS is allowed to use Wi-Fi to increase location accuracy?
How about anonymous statistics sent to google?

I set up GPS only. (On Xperia M2 even when Wifi is used to increase accuracy of GPS, there is no data transmition when it is switched off).
I refused anonymous statistics everywhere it was possible. If I do not agree to send data to Goole it is not possible to switch on high accuracy mode.
I though that Mobile Data button is some kind of master switch.
Sony Select informed me about possible data transmition and there was no possibility to refuse it.

Yea. There are mysteries which neither I could figure out.
Once a time mine statistics showed traffic even when I had data transmission off !!!
Folk here said is is literally impossible. (my suspicion was - application itself switched data transmission on in the background for a while).
I suspect that statistics count packets when they are designed to send, not checking if firewall or anything else really allowed them through.

Yes, same me. I think Sony did something wrong or did something on purpose to monitor people. Nowadays almost every one have data transmistion offer so they do not care about small traffic.
I contacted Sony support to solve that issue. Anyway this is my last smart device from Sony. If my issue is not solved I will flash my cell with custom rom.

I installed Cyanogenmod 12 and problem disappeared.

On stock Sony fw if you turn off mobile data and WiFi in setting about your phone you will see:

This is too simplified conclusion.
Such descriptions are worthless.
It as well can be about packet transmission without which you could not send/receive SMS.
(This would explain that it goes down in plane mode where you dont send SMSes).
As well can be that data service is in listen state.
Only knowing amount of transmitted packets would tell us more truth.

All the time the phone is on it's constantly connecting to the local telephone masts and negotiating a connection. Without this function it wouldn't work as a phone. Google uses this mast connection data to work out your location. It's possible that the data usage you're seeing is a part of google location. This is nothing to do with 'data' on your phone. But if you're concerned why not install a good firewall ?

I have disabled google localization and block all nlp things with wakelock terminator. I use mobile data transfer all the time so for me that's not a problem but there are people who don't use mobile data and have active data traffic so it's suspicious that in Sony phones there is such a weird thing

Detailed battery history shows wi-fi allways on

Hi everyone, when checking my detailed battery usage, my phone showed that the Wi-fi had been on all the time, even though its turned off in the settings? Anyone else have this issue? Or does anyone know how to fix it?

Settings > Location > 3 dots on top > Disable WiFi/Bluetooth Scanning

Not questioning your knowledge but I saw that everytime I used maps it gave me a location settings pop-up and if you pick yes it switches on WiFi and Bluetooth scanning for location. Check if that's the case.
Else it could be a hardware issue.

I had this also on my Nexus... And wondered how to turn wlan off...

Go to Wifi -> 3 dots on corner -> Advanced Wifi
Check for a setting named "Keep Wifi on during Sleep" and it will have 3 options (set to "Always" by default).
Choose "Never" and it may pop-up a warning of increased data usage.
Check battery life after 3-4 hours (with Wifi toggle OFF) to see if the graph shows anything in that Wi-Fi row for those 3 - 4 hours (i bet it wont )
Simple!!

Same for me, i have done this fix but wifi is shown on in the battery menu. Hotspot is off... I don't Know...

If you have viber go to general settings > WiFi sleep policy and check use device's settings.

Ive also discovered that my Oneplus 3t seems to switch on and off the WiFi when I'm using it. Have switched off the scanning too. Any ideas why?

If you use High Accuracy location settings it will turn on your GPS and your WiFi. Google's device manager will use high accuracy settings and you will get GPS and WiFi on almost all the time.
Try setting you location to device only, which means GPS only. This will stop it from using WiFi for location reporting

No Mobile Data after 4.27.617.2 update

My phone came up with an update yesterday, and installed no problem.
It was only later while out I realised I had no mobile data while out. No matter what I try it will not connect to mobile data. If wifi is connected the mobile data states, ' Use my data plan when Wi-fi isn't available.' As soon as I walk out of range of the router the wifi drops and I have no data at all. If I turn wifi off but leave data on. the mobile data states, 'Disconnected.'
There is no apn listed. It states, 'Access Point Name settings are not available for this user. It does allow me to go through the process of setting it up manually, however it says it has saved it, but nothing appears. I have tried both saving and using the back key, neither works.
I have tried rebooting, flight mode toggling and nothing. I have taken my sim and put it in my daughters M9 and data works fine. I put her sim in mine and nothing. I can make calls and sms but no data. I have trawled through pages of xda and google and none of the solutions work.
I have also done a full system reset to no avail.
Can anyone give advice? It was working great until the update yesterday

Weird indeed. Have you tried re-flashing the RUU? That would re-apply the software to your phone (rather than just re-setting what is already there). Might make the difference.

Thanks. Do you have a link to the RUU?

Check out the readme thread - it's got RUUs for the 617 SKU (your variant, from your OS version) in the 5th post. If you're new to RUUs, do take the time to read through the thread. It's a quite a bit of information, but it helps build a common baseline for future support questions, if you end up having them.

I have the same problem, any solutions?

Try re-registering to the network then edit the apn settings or ask your carrier to text the settings to your phone.

Mobile data never really turns off but shows disabled.

I'm having this issue where once I boot into Android and I disabled mobile data and use WiFi, everything will work as intended. If at some point I enable mobile data and wait a few minutes I can disable WiFi and mobile data yet a data connection is still available. Icons show up as being disabled but this is false. A reboot will clear the issue but returns as mentioned. I removed as many apps as I could think of that may have something to do and checked developer settings to fix this behavior to no avail. Anyone running into this?

I'm not sure but it could be that in developer options there is a setting to keep mobile data always enabled. Try to turn it off and see if there is any change.

This was fixed by changing my T-Mobile APN and now for some reason it works as should. Was using "wholesale" as the MNVO APN previously.
