[Q] Permanently Disable Wifi? - myTouch 4G Q&A, Help & Troubleshooting

I seem to be having issues with every ROM concerning cell signal. I can't get 2G/3G signal at all, and can only get 4G signal when in the right area (as expected).
I think it has something to do with my malfunctioning WiFi. It constantly just tries to turn itself on, with no success. I'm quite positive that my WiFi is broken due to hardware problems (internal coaxial cable, etc) as I have flashed several ROMs and radios with no positive results in order to try to fix it. I've even tried unrooting and returning back to stock.
What I was wondering is it possible to permanently disable WiFi on the MT4G so that I can try to get around this issue?

You could flat out take out the wifi radio chip.

Ah, THEindian. To what do you I owe you for the grace of your presence?
The problem with that is really just that I don't have the torque screwdrivers or a phillips small enough to disassemble the phone. I was looking more for a software "fix". I'm not really even positive that the WiFi has anything to do with causing issues with the 2G/3G reception.

Delete the WiFi Modules from system/libs modules folder and it will disable delete Wifi

The only file in that specified in that folder is "bcmdhd.ko" removing this file will fix my issue?

Yes. That's the wifi module.

So, I renamed the file to have a .bak extension. It did accomplish what I wanted to (disabling the wifi and preventing it from turning on constantly) but it did not fix the real issue of not being able to recieve 2G/3G signal. I don't know what else to do.

Yes, I am a T-Mobile US customer. APN settings should be correct according to the support docs on the T-Mobile site. I've made a few other adjustments to this ROM's build.prop to the wifi settings. Set it to use eth0 as the interface for a while rather than wlan0. Still hoping there's a software fix for this mess.

That seems to be the only option I have left. I just fear that I'm going to break something and then revert back to using an old Samsung Gravity because that's the only other GSM phone I have. I'll have to find a place that sells small enough torque screwdrivers as well as a phillips head small enough to take off the screw under the "Void" sticker.

Well you could disable on build.prop

Ebay.

I'm actually thinking about using my friend's old unlocked iPhone 3GS for a while (maybe they even refarmed the 1900's around where I live to get 3G by now) until I can scrape up the cash to get a One S.
I'll put the whole story of my phone's downfall here to see if somebody can figure out what it is, or maybe even try to prevent it happening to others.
Bought the phone back in February 2011, and it worked perfectly fine up until April 2012. During this time I was running a Sense 4.0A ROM (can't recall the name) and my phone had died from battery drain. When I charged it up and turned it back on, my WiFi was no longer functioning. It would just repeatedly attempt to turn on and switch itself off again.
I flashed several different ROMs and radios to try to see if I could fix it. No luck. I then suspended my line from T-Mobile's service from June 2012 up until 2 weeks ago. When I had my service restored, I no longer had 2G/3G connectivity. By this, I mean when I'm in an area that does not have 4G coverage, I'm greeted to a "Limited Signal" message and cannot send texts or make calls. If the area has 4G coverage, I can do everything as normal with no problems.
I flashed several other ROMs to see if it was just an issue with that, no luck there either. I then just proceeded to unroot and return to stock. I was never successful in turning the S=ON (none of the guides posted worked) but did lose root privs and bring myself back to Stock Froyo.
None of this has worked so far. Since then, I've re-rooted and reflashed cnote's ICS MIUI build and here I stand.

[Q] Evo Shift keeps rebooting

Looking for some advice/help. I got my wife the Evo Shift a couple of weeks ago. Her phone has not been rooted and other than a few added apps the phone is completely stock. The phone reboots on her 4 and 5 times a day. She does not have any kind of task killer installed so that's not it. She plays Angry Birds a lot and uses Pandora quite a bit. I have also installed Sound Manager for her. Other than that I can't think of anything that would be helpful for trouble shooting. I have searched here and through Google and have not seen any info of others having this problem. I am not sure if I should root the thing or return it to best buy. I have the Evo and previously the Hero and am no stranger to rooting or custom ROMs. Just really did not see the need to root it since my wife has no idea about any of that. Any help or advice will be appreciated.
Thanks.
root and install nfinitefx's or mik's rom; you'll have less trouble than if it was stock.

That's what I was thinking. I am a little worried its a hardware problem though. I guess I could always flash back to stock and return it if that doesn't fix it.

Not yet. I did get some more info from my wife though. It only happens when she is at work. And she says she get some sort of "radio error". I'm starting to think it might have something to do with the building she is in. She had my hero for a couple months before I got her the shift and had no problems. It had CM 6.1 running though.

im running mine stock and rooted and dont have any problems with reboots. sounds like a app is probably screwing something up
i had a similar problem with one of the streaming media apps i used to use a month or so ago i cant remember the name but for some reason if i lost signal it would crash the phone and need to be rebooted
i took it off and installed tuneinradio and it worked better anyways
My shift was rebooting itself 3 to 4 times a day, I just rooted it and it seemed to stop rebooting itself for a day. Now its starting to reboot itself again, but not as often.
I am almost convinced its a hardware problem. Sounds too rare to be anything else. Maybe bad memory or something.

I had a freezing issue with my phone which people suggested possible due to pandora and bluetooth. Perhaps you have the same issue?
Anyway, try to find "bluetooth for automotive" settings for pandora and turn it off.
I wouldn't recommend rooting your phone if you think its broken. You might just end up breaking it further and render your warranty void.
If you can't fix it, get sprint to replace it.
i dont need a signature
This may be resolved by now, but I got my shift previously used. When I first activated it, I was getting some radio errors and I could not make calls or send sms messages, but the email worked fine. I contacted Sprint customer service via chat from the website and they did something from their end to fix it. I had to turn off my phone and she said now wait till I tell you to turn it back on. I waited 5 minutes and when I turned it back on, everything was fine. So I would take it in or contact Sprint and see what they say. As for not sure if you wanna root it for her, I would definitely recommened it, she doesn't have to take advantage of all the advanced tweak that some use but it will just make the phone a lot smoother and easier to use. IMHO.

Thanks for the input. I think I'm going to go ahead and root it. After keeping an eye on the situation its seems its only happening when she is at work. I can't imagine it will fix it but I think its worth a shot.
I think I fixed mine. I tried to use navigation and it kept force closing, that was strange because I've used it before with no problems. I googled around and found some info that if you had another text to speak engine in your phone then uninstalled it without setting it back to pico as default it would cause nav to FC, which is what I had done. So I set it back and checked "Always use my settings" in the Voice section of settings, nav started working and the reboot issue went away for the past 7 days.
I don't really know crap about phones and most tech stuff for that matter (heck 99% of what is said in these forums goes over my head) but I think why this fixed it is either nav or some app was trying to use pico or something and when it couldn't the phone would get an error and reboot itself. I may be wrong (probably am) but maybe she deleted something or changed a setting some app needs and that is causing her problem. Hope this helps in someway or at least gives you another direction to start checking.

**DEV REQUEST** 4G Idle timeout change

This is a request to the devs out there.
I just wondered if anyone was able to get into the 4G / Wimax settings on the phone ?
I'm interested to know if there is an ability to increase the length of the 4G 'idle' timeout.
The debug menu (*#*#33284#*#*) seems to have all WIMAX settings locked down, and I windered if there was a way to look at these via adb ?
I've heard that you can increase it to a max of 300 minutes ?
Something like this for the Evo ?

Not the same as the evo. Idle is a feature. When internet isnt in demand, it idles. The time has nothing to do with idle.

This feature is f**king my internet connection up. It basically disconnects, and won't reconnect on incoming push notifications. I've had this confirmed by Sprint, but posts to the contrary on other threads make me think something odd is going on.
I'm losing the will with this idle feature.
What Rom and kernel are you using? I do know some kernels force a file called wimax_service.dex in /cache. My pushes seem to work fine. 4g turns back to reception bars when needed.
Uncle Jimmy says hello
Im running MIUI so I dont have 4g, but I also have an epic, and the wimax settings can be changed on it also. You have to access the data menu with wimax on, on the nexus it would be *#*#3282#*#*, then "edit", enter you msl, then go to wimax or whatever it is. As I said, Im on MIUI, so I dont know if this is even possible with the nexus. This is what I have my epic at:
ScanAttemptTimeOut 00005
ScanRetries 00120
IdleSleep 00300
EntyRX -00094
EntryCINR 0004
EntryDelay 00001
ExitCINR 00008
ExitDelay 00300
Tell Sprint to f**k off and go to T-Mobile. I'm really close to doing that. I'm pissed beyond belief.

Honestly I've tried everything. It has to be a configuration setting somewhere. I can't believe this is normal. As you say it should kick back in for push.

?? Can I ask what this is/does ?
im also looking for ways to edit the wimax settings. it doesnt seem like theyre blocked.. it seems like the apk's that were used for those menus arent even on the phone. has anyone tried taking the wimax apks from the epic to see if thatd allow us to do anything? if not, ill be trying this eventually.
hard finding people to talk about this wimax editing stuff. ive also noticed.. at least on my phone.. when running the commands to "backup wimax.img" that my image has NO unique data in it.. its just filler space, FFFFFFFF over and over. is this the case for everyone else?
and heres a post i came across explaining all of the EPICS system apks.. including the above mentioned ODB.apk.. which says to leave it. but this also has the wimax apks. and im hoping they'll work on the nexus.. as it seems the wimax in the nexus is EXACTLY the same as the epic. http://forum.xda-developers.com/showthread.php?t=773142

installed the wimax apks from the epic.. didnt work. lol. also.. tried dumping the phones memory with cdma workshop which doesnt seem to work at all. com port always disconnects. ideas anyone?

[Q] Remove the phone aspect?

But I have recently picked up a replacement phone for my aging MyTouch. It's still a good piece of hardware and instead of selling it..I want to re-purpose it into a media player/car computer.
While it's easy enough to just not have a SIM card installed and will due this if there are no other options. The problem is you get that annoying 'no SIM installed' icon at the top. As well as all the functions that where used to make this a phone. It'd be nice if they where just *Poof* gone! So the question really is, does anyone know of a ROM that does this? Preferably ICS.
I know this is an odd question. I'm also open to other ideas.
Just put it in airplane mode, that should do. You can still use wifi
Sent from my HTC Glacier using XDA
Hmm, I tried it before and noted that both my Wifi and Bluetooth had turned off. So I tried turning them back on after I put it into airplane mode and they both worked. It's a temp fix but thanks none the less.
Dont just open the Rom and take out phone.apk, you'll force close loop.

Downloaded and will be flashing this real soon. Thanks for the info. I'll let you all know how it goes.
Well flashed the zip to my phone. It didn't brick it. About all I really noticed is that it essentially put it into a permanent airplane mode. While it deleted the apps for making phone calls it had no effect on the parts of the ROM that render such things. For instance I still have shortcuts for making calls, the indication of 'no service' is still present, etc. This makes for a great stop gap, but to truly achieve what I'm looking for will require a completely revamped ROM.

[FIX] Note 3 GPS Issues

If this helps you I would appreciate it if you hit the "Thanks" button on this post.
I can finally 100% confirm that the GPS signal lost issues we have is software related.
The best workaround I have found for this is to:
Root your phone using Kingo or whatever root method you prefer
install KNOXRAID
@drakeymcmb made this ROM, so you know it's going to work.
***WARNING TO ALL USERS***
This thread is not a "Best ROM" thread and will NOT be treated like one! Possibly any ROM that's "rigged" will fix the GPS issues, but this is currently the only one I have found that works right every time.

UPDATE: I wanted to add that if you have a AT&T ROM installed (may work on other ROMs, but definitely ask drakeymcmb before trying anything with a different ROM), Drakeymcmb has a fix here I'm quoting.
I already posted a fix for this issue a few days ago. Here is some feedback that I got. And here is the dl link.

I have two AT&T Galaxy Note 3 and I had exact same problems on both Note 3. (GPS was turned off when power was plugged in or out and the connection switched between 4G and 4G LTE)
First, I did factory reset to my one of Note 3 and installed only GPS Test APP on the stock with rooted to test GPS. It seemed to work well when power is plugged in or out and then I installed Apps that I need and checked if GPS worked well whenever an App was installed. It looked like the factory reset fixed the problems but the problem happened again after about 12 hours. (I did this last night and GPS worked well before I went to bed but this morning, it happened again)
Frankly, I hesitated to apply this fix because I did not have enough information and did not know how to apply this fix but I thought it was worth trying this fix.
Here is how I applied this fix. (I think this is not the best way but this is what I can do with confidence. Please be careful and do this with your own risk)
1. Backup the following files
/system/lib/hw/gps.default.so
/system/lib/hw/gps.goldfish.so
/system/lib/libloc_adapter.so
/system/lib/libloc_api_v02.so
/system/lib/libloc_eng.so
/system/etc/gps.conf
2. Unzip Gpsfix.zip
3. Copy the files in the zip to the corresponding location.
4. Change the permission of the files to rw-r--r--
5. Make sure if the owner of the files is root
6, Reboot
After that, I tested GPS with my two Note 3 (one has the fix and the other does not).
The one with the fix works great when power is plugged in or out or the connection is switched between 4G and 4G LTE while the other one has still same problem. (after several testing, I applied the fix to the other Note 3 so my two Note 3 are working well now)
So far so good. I will update if I have any changes.

good ****. got lost a few times because of the gps.
I will 2nd this "fix"...
I actually rooted/SS/ROMed my phone a few days ago because I saw that it did possibly fix the GPS problem.
I was having the issue where GPS would disconnect when changing cell towers, or if I plugged/unplugged the power from the phone. I could reproduce it very easily.
So, I installed X-Note, and did some testing yesterday, and did not have a single GPS drop in over two hours of testing. I was also able to plug/unplug the power without losing GPS signal. On the way back to work this morning, I switched back to my stock ROM slot in SS, and the issue was back.
I do NOT know if the issue is fixed with any other ROMs. I have only tried X-Note at this point.
Would be great to know what is actually causing the issue with the stock software. Samsung still plays dumb about the problem, acting like they have never heard about it from anyone. I was very close to getting a replacement from AT&T under warranty, but just hadn't gotten around to it yet. May still do that if I get the urge/time to put everything back to stock. I just don't want to end up getting a "refurb" from them. I've gotten one on a past phone, and it was a piece of crap that had more problems than the one I turned in. I'm not sure how much testing they actually do on a refurb phone before thinking it is ok to give out to someone else.
I exchanged my phone 4 times with AT&T before I accepted a replacement. I complained each time about their lack of testing. The 4th one they sent was brand new. If you get a chappy phone, keep requesting replacements.

I too can confirm it's some sort of a software/app conflict problem. This is what I posted on AT&T's forum:
Like you guys I have been doing the same thing. After wipe it seems to work fine, and I do suspect it's a software issue. I was actually in the process of writing an update here last night, as I was writing I decided to check it one more time to be absolutely sure I'd gotten rid of the problem when it happened again.
At the time I suspected the Flipboard widget that's preinstalled on our homescreen as that was the last app I started up before it happened. So then I wiped my phone a second time last night to test out Flipboard, but to my dismay the GPS continued to work perfectly even after I had signed in to the widget. Then I suspected GSam as that was the app I set up prior to Flipboard. So I left GSam uninstalled since the wipe last night, everything was still working until a few hours ago. I was going to drop by here and give an update when I thought, okay one last test... then boom we're back to square one.
It has to be some sort of software issue as all 3 of us have noticed, a factory wipe without installing apps/backup restore works but after we install our apps and use it for a day or so it bugs out again. But I can't think of what might be causing it, what app could affect the GPS chip like that? Plugging/unplugging normally has NOTHING to do with the GPS, so why is it causing it to shutdown. And the 4G LE to 4G switch too, it's on a separate radio, so how does it affect GPS? This is beyond annoying but at least we've been able to confirm with a 80-90% probability that it's not a hardware problem.
To add to that, once the problem has been triggered, even if you boot into Safe Mode it still exists. So it might even be something in the firmware itself. The only way to get rid of it is a factory reset or flash a different ROM like others have done here. Sometimes I do really HATE AT&T. Seems their ROMs are the buggiest and most untested out of the 4 major carriers and on top of that they lock our bootloader too.

Being that it's software, we don't know what the trigger is. It could be any combination of things. For instance, it could need things to be done in a certain way to set it off, like say setting up the My Magazine then hitting My Story then going into Flipboard. And if it's not done in that order it won't set it off. When you reset your phone and set it back up, do you always do it in the exact same order each time? This app first then that app? This setting first then that? No, it's always in a different order.
Deduction tells us that it's software. Can't be hardware if it works right? Hardware either passes or fails, there isn't an in between. So if all of us that do a factory reset and it works until we start personalizing it, then obviously the hardware works right? And those guys that posted above about going to X-Note ROM and their GPS works correctly shows that it's not hardware right? Hardware can't choose to work with certain software and be faulty with others, that's the software's doing. The guys above aren't the only ones to have it work perfectly on X-Note either, a few others on other Note 3 GPS threads and a few on the AT&T forums have said the exact same thing, going to X-Note solves their problem.
One last thing to consider, GPS and wireless radios on our phones are different, AT&T may not have been able to test each model extensively on their ROM and Samsung may have. Take off your back cover and look at the top right corner, judging from the Note 2 that should be your GPS chip, see that number? That identifies the model of your chip, I've seen people say they have 1-4 or 1-3 or 4-4 or 2-2 and so on. Each batch with the different chips Samsung could have tested extensively to ensure their ROM works with all those chips. AT&T probably does not as they probably don't pay attention to those components because they're not the manufacturer.
Everything in this world is based on deductive reasoning, you use it whether you're a car mechanic or refrigerator repairman or computer technician or help desk or even doctors. What do you think House does? That's what most doctors do, they make an educated guess based on symptoms and if they're wrong, they've eliminated one possibility and gone on to the next until they find a cure. Deductive reasoning at work, and so is this thread.

This is my thought after reading about simular problems with other brand Android phones and also some iphones. There's a technology used by some but not all phones called aGPS. What this is a gps that relies on cell tower assistance for better gps tracking. From all the simular complaints this theory is a match. Another reason I come to this conclusion is that the gps - cell - wifi - and Bluetooth are all independent components. But if you put your phone in airplane mode and try to use the gps it won't be able to lock onto your location. But other Android phones are able to do this in airplane mode. Then I tested the theory and when I enable the wifi the gps locked dead on my location. Then I turned off airplane mode and let the cell sign connect and I hit locate and it did the same thing as wifi. So some how the gps is linked to aGPS.

This has NOTHING to do with A-GPS, this thread is not about the GPS taking a long time to fix, please don't convolute it. A-GPS has to do with TTFF, it doesn't switch off a GPS chip. I suggest you do a lot more reading on A-GPS and understand what it is. And read what this thread is about, or GPS chips pretty much TURN OFF when we plug/unplug the charger when we ALREADY HAVE A LOCK. And the it does the same thing when switching network from 4G LTE to 4G.
I don't know what you're talking about with your "tests" because first of all they have nothing to do with our problem discussed in this thread and second you seem confused. Let me clarify for you.
Firstly, we don't have a problem with fix or how long it takes to fix or if it even fixes at all. We all get SOLID fix, our GPS loses signal at the plug/unplug of a charger and at the change in network i.e. going from 4G LTE to 4G. Do you see why your "tests" have nothing to do with us? You see why you're confused?
Secondly, you must be confusing not getting a fix with not loading a map. Without mobile data or WiFi your favorite navigation program will be unable to LOAD A MAP, not unable to obtain a GPS fix. And without mobile data and WiFi (here's where the A-GPS part comes in) your phone is not getting A-GPS data which gives you a slower TTFF. But if you wait long enough it will eventually get a fix. Use a GPS test app so that way there's no map to be loaded and just wait in airplane mode, you'll get a fix in less than 30 seconds.
Are things clearer now? Let's not convolute this thread for people coming here seeking answers to their problematic GPS OK?

I'm not confused. Loading map has nothing to do with the tracking of the gps. The gps radio relies on cell coverage.
Here read this

Anyway I hope the fix fixes the gps issue.

The problem is the GPS radio turns off and stays off when switching from LTE to 4G and vise versa. Doesn't really have anything to do with getting a fix on a satellite.
A bit testy are we goldendragon? Lol
Came back to edit this to say I'm still laughing 5 minutes later lol

Ok fine. Since you asked nicely. First, have you even read what I wrote in my first comment to you? Did you do what I said? The part about testing with a GPS test app so there's no map to load? You can even use Google Maps, it just won't show you the map but it'll get a GPS fix.
The map is only stored in the cache if it's loaded that area before. The entire map of the US is not going to be stored in your cache, not even an entire zip code. So there's no cache if it's never loaded that part of the map before. BUT as long as you've got a blue dot with a pointing arrow then that's your GPS fix.
Had you read or done what I said, you'd find that your Note 3 works fine without A-GPS and it does not need an Internet connection. Put your phone in airplane mode then open up Google Maps and leave it open and just wait. After a while you'll get a fix, better yet download GPS Test and open it in airplane mode. Can't be any easier than that.

I read what you posted. When I do the test with airplane mode on I get nothing even waiting after a minute or so. That's why I was under the impression the note 3 gps is a A-GPS. Heres a screen shot I took.
There's no blue dot nor arrow. But if I turn on wifi it instantly locates my location.

Ok it's not that a phone is A-GPS or not, it's does it use it in conjuncture with GPS. Assisted GPS just means that instead of letting the GPS chip do all the work, your location data is sent to your phone over mobile data or WiFi to Assist the GPS in figuring out where you are. So without the information sent over your GPS will still work but just slower in getting a fix. That's why I linked you that article. And that's why I said you were confused in the first place, I wasn't being mean then, at least not yet anyways.
Wait longer or like I said download GPS Test and see what's going on with your GPS chip. Download it then put your phone in airplane mode then run that app. Wait and see what it says. I don't know how long is the average but my phone gets a fix in airplane mode in less than 30 seconds, but if yours doesn't get it that quickly then just wait longer. But using the GPS Test app you'll actually see the satellites and how strong the signals are, it'll let you know if your GPS is actually trying to get a fix or not. Try it with the app and see what happens.

I tried the app my signal is only 22. This is where I get confused my note 2 was able to use gps in airplane mode and without cell service. It was accurate. But for what odd reason I can't even get a location lock in airplane mode on the note 3. I know it's been said it's a software issue so has any tested the gps in airplane mode to see if it is actually working?

22 what? Take a screenshot. I have and it works perfectly fine in airplane mode.

I can finally 100% confirm that the GPS signal lost issues we have is software related.
The only workaround I have found for this is to
root your phone
install safestrap
install X Note
from the Android Development section. It's a ported international ROM which means it has all the GPS files from the International version.
:good:

I was on the phone with tech support and we went through the entire thing. I did a total restart of the phone and reinstalled all the apps. So far so good. Worked fine on a couple of errands today. I did not reinstall any app that deals with downloading AGPS however and my phone still locks pretty quick. Will follow up in a few days. BTW version of phone as far as I can make out is 1-1

This may be a stupid question but does this fix work with the stock ROM (ie rooted and SS installed)

Flicking icon to 4g when WiFi is on.

I have strange thing happening when I'm connected to wifi and data is on its constantly flicking from one to another? Anyone have same thing?
Had the same problem on the EU version B03. I Deleted the apn's. Manually add them again and now it's working perfectly for me. No more flickering.
Tks have eu version as well I try.

I would have never though that this is why it stopped on my phone. I did it quite different purpose. ?
I'm relieved to see that I'm not the only one having this issue after updating to B03, even though the change log mentions that this issue is resolved. I've tried a factory reset and APN deletion as suggested but it doesn't help. I've moved from a OP3 to the Axon 7 recently (very difficult decision) and as much as I like to tinker with my phones, I suppose the EU folks have to be patient to enjoy the true potential of this device.
Hoping this issue gets a workaround or the next update fixes it. For now, assuming this flickering takes up battery, I've just disabled mobile data from the quick toggle.
P.S. Iv'e tested it and I'm pretty certain that it doesn't indicate that the Wi-Fi is continuously disconnecting. It's just the icons acting up. Also, no mobile data is used while this happens.

May I ask how you delete the APN? The only one I have is greyed out and I can't seen to delete it. I created another one and mirrored the settings from the original which seemed to do the trick but alas I was wrong.
I have the US version but flashed B03 onto so I could enable the on-screen sift keys with Gravity box.
Thanks!

It was only working temporarily. Have the same issue again with update B05.

in my case i had this problem with B03 and never changed APNs, upgrading to B05 fully solved the problem (just checked, APNs are still the same as B03 for my operator)

Have you tried repeating overwrite APN again?

Yes but it didn't work this time unfortunately.
This is such an annoying issue to have. I initially thought this takes no battery being just a cosmetic and not a functionality issue but I'm inclining to believe that it is actually switching to mobile network and back. Can anyone confirm this?
I think it is there was some app don't remember name witch check all network info and u can check there when is flicking it's changing status from wifi to 4g

I just ran a quick watchdog test and watched a video on YouTube for a few minutes. I also have a flicking 3g icon. After a few minutes on YouTube with flicking icon there was 0 bytes used on mobile data, so I guess this is just a cosmetic problem.

I was certain there was no data loss, however battery loss maybe a possibility. Purely speculating.

Since I don't really trust my GSam, I have no idea how to test this. At least it's not using mobile data, that's for sure.
