[Q] Z3C connects to mobile internet although disabled - Xperia Z3 Compact Q&A, Help & Troubleshooting

Hi,
currently, I don't have an unlimited data plan, but switch on mobile internet on demand, for a single day. Most of the time I'm using wifi.
Now, I own my Z3C only for two weeks. Some days ago, I was travelling and thus configured and switched on mobile internet for the first time with this phone, for a single day. I am pretty sure I switched mobile internet off in the evening.
But looking into my provider's online overview today, I noticed that since then, my phone used mobile internet from time to time (about every five hours or so). The amount of data seems to be low (<1kB), but anyway, up to today that triggered four additional days of mobile internet usage without me needing that and even without me knowing that.
Can anybody explain what's going on there - and especially how to switch that behavior off?
The phone is stock, unchanged, and unrooted (all updates installed). No MMS have been sent or received. The data usage in settings does not give any helpful information.

Your not alone, im having the same problem. I haven't found any solutions nor any reference to such problem until now. I also have stock rom, hardly any additional apps, turned off automatic updates etc. But it still connects to internet, behind my back for A SECOND, sometimes in every ten minutes, sometimes once a day. A temp solution is to delete the APN settings, but this does not solve the problem.
SO CAN ANYONE HELP US?

I have a guess. It's either Anonymous data sending or phone usage. These two .apks send anonymous data to Sony, probably even using mobile data. It's a guess tough.
Nevertheless, I have removed them since I'm rooted.

You can try Onavo, but I believe those services will be masked under OS/Android, so it's hard to pinpoint them.
Also you van try the default app in > Settings, Data Usage (Mobile Data only)

In the meantime, I found a cure: Changing Settings -> Location -> Mode from "High accuracy" to "Battery Saving" immediately stopped the network access.
According to some other forum, assisted GPS is the reason, so using either "High accuracy" or "Device only" will both cause GPS to ask the mobile network for AGPS data from time to time. It is yet unclear to me why this also happens when I have an active WLAN connection.
With that knowledge, removing ",supl" from the APN type (and saving the APN afterwards!) could also disable fetching of AGPS data from the mobile network while mobile internet is switched off, but I didn't test that yet.

Hey
thanks for the update, i'm gonna try first "device only" (i had it on high accuracy) and after the APN type change and see if i get any changes.

As far as I understood things, that will not help, because "device-only" still activates GPS and thus still uses AGPS.
Did you try it already? What are your findings?

I just checked, it made no changes (device only). Today from 00.00 to (strangely) 11.00 clock, is the internet on/off count 53 times. I can see that the connections were 0 sec and 1 kB. So what now?

So i switched GPS off all together, and it seems to be working, no internet connection has been made. I also noticed that for a while the device changed the settings from device only to high accuracy itself. I deleted the ",supl" lets see what happens.

Actually the phone stopped surfing on its own before i deleted "supl" and i think the problem was google and its location history. Im going to test furder. Did you get it under control?

So, over a month has passed and i have some good and bad news. The good news is, that the problem for me has stopped(12.02), the bad news is, i don't know why. I made many changes and now i don't know what affected it. But my guess is that it was the deleting of "supl". Because in one month i had all the settings(location, battery saver etc) on and off and it didn't affect the data usage. 16.03 i got lollipop on my device and this also didn't change it back.

What is the deal with the weather plugin?

That's what the "download weather data automatically" setting will do...it will attempt to get an internet connection and update the weather when (and IF) you click on the Weather Plugin. The thing is, it will want to do this every hour from the previous weather update.
TEC
And what about disconnect? Is it possible to auto-disconnect after the weather foreground is downloaded?
It's very annoying if you don't have a data plan or if you want to save battery to have to do a manual disconnect.
I want that too...
Yea...I've been looking for a way to AUTO DISCONNECT as well.
Anyone have any ideas??
AH…
I guess I was looking for more finite control over this. Ideally I don’t want to see “attempting to download data” when I click the plug-in. I would rather it just download automatically in the background instead of the plug-in having to check the web at the moment I hit the icon.
Maybe I need to hack the reg to leave GPRS always on?
Hi
By design the data connection remains connected for most Windows Mobile 6 devices, it doesn't mean data is being passed or power consumption is increased.
An article here explains about data connections remaining "On".

Interesting
Also, Mobile Operators requested it. It was more expensive for them to be constantly creating and tearing down connections than to just do it once. Finally, staying connected enabled us to develop a fast "push email" client that relied on the device holding an IP address.

What about my battery life?
Just having a data connection shouldn't affect your battery life. Most of the time, the device isn't doing anything with that connection. It just sits there idle. If you're sending a lot of data over the connection, though, that will definitely impact your battery life. Unfortunately, the arrows don't really tell you whether you're sending data or not (though I've seen devices that animate the arrows while data is being transferred).

And a interesting quote from a user
In GSM, when you are constantly attached to GPRS, your battery does not spend more energy because there is absolutely no communication between the network and device if there is no data transfer (however there is still periodical normal GSM communication). Only difference is if you are in motion and changing cells in time. Network keeps track of your GPRS connection via "routing area" which consists of one or group of cells. When you switch to cell that belongs to adjacent routing area, there is a, very short, "routing area update" exchange of information between phone and network, regarding GPRS only. But that is very small power consumption.
The same thing is with UMTS. The whole goal of any network is to bring communication traffic to minimum. But, with UMTS, channel coding and transmitting technique is much more complex than with GSM. You are attached to multiple cells at the same time and there is very, very, very strict phone transmit power control. That means that phone must do a lot more signal measurements from group of cells (much more frequent than GSM). It could possibly happen, if you reserved more channels for packet data transfer, that a lot of signalling happens. However, there is a inactivity timeout here which puts you in standby mode as in GSM and then you do not spend battery for packet data at all. But this is all complicated, it depend of many factors: signal strength, network settings, number of users in your location area, etc. .. If the network signal is weak, than any phone in any type of network will eat up your battery.

I'm going to try this theory out for a couple of days
if you were to read the manual that came with the phone it states that this is exactly how the weather tab works. If auto update is enabled it will automatically update the forecast every time you touch the weather tab.
Honestly it seems a little silly to me. I have auto update turned off and just tape the last updated time at the top to manually update it.

We are on the same page flexte, but it would appear that as of yet no one has figured out just exactly how to tweak the plugin to do what we want. As Jason Lee mentioned it is working like the Manual says it should. Hopefully this will eventually get tweaked!
has anyone figured how to get rid of the "attempting to downlad data" message yet?

Strange data issues. How to track down malicious apps?

Alright, I really need some help from the big boys here.
I have had my N1 since release. I have T-Mobile and no data plan. Everything I do is over wifi.
On Friday, I saw the 3g icon on my phone for the first time. It appeared out of nowhere and just flips between 3G and E since T-Mobile just blocks data for non-plan users. This was killing the battery life of the phone.
I called Google and they ran me through *#*#4636#*#* to disable the data connection. This fixed the problem for a while; However after a while the phone will give a message that there is no service provider and will reconnect to T-Mobile (it has never done this before outside of phone boots). When it is back up the 3G/E cycling starts again. Even worse the data connection still lists as disabled and will not re-enable. I have to pop the battery out while it is running to get back in to disable it.
Google thinks its an app but I have removed everything but Touchdown and K9 which I don't think are the problem. I have used Android OS Monitor and I do see connections to 64.15.75.218 and 209.44.107.13 which are hot beds for malware and when I uninstall any app these connections vanish temporarily. But they come back after a few hours.
Anyone seen this before or know a way to track IP connections to a particular app?
I have no solution for tracing 'malicious' software but it is possible to just disable all mobile data usage.
Settings/Wireless and network settings/ Mobile networks > "Data enabled"
If you unselect this there should be no more data transfer while on the mobile network.
I do not have that option. Google Rep said it was only in froyo.
Problem is I did the same thing for 2.1 but it keeps coming back on. Even with wifi the phone connects to these ips so who knows what it is doing.
3G isn't used only for data, you can do voice on 3G.
Could be T-Mobile expanding 3g into your are where you didn't have coverage before.
Call T-Mobile and make sure you're not actually using data.
As for tracking applications, you can use System Panel Pro of the market to monitor how much data applications are using.
I know I am not using data. The T-Mobile account page is pretty detailed and I am unable to do anything online when wifi is off. 3G has also been available for a while here as I know others that use it.
I will check out system panel.
Thanks.

It is indeed only on Froyo, however, Froyo is out now, so install it and you'll instantly benefit.
A few more things:
Were you receiving or sending MMS (picture/video messages) when the 3G icon popped up? This is normal and doesn't usually come out of your data balance.
If you'd like to be triple-sure you're not using data, go into the APN settings. Edit the APN name - e.g. change tmobile.com to nomobile.com. Now it *really* shouldn't be able to access data.
Smarphones would be well to do to have a Zonealarm/little snitch type app for this purpose.
Id imagine ad based apps wouldnt be too happy about it. At the least an app that reports IPs times , and IN/OUT info.
I never use SMS or mms and have not gotten any during this time.
My concern is not related to getting charges but with unwanted use of my phone or data. When the data connection auto enables it will go through my battery in a matter or hours and who knows what the phone may be doing.
I know I can turn this off and make sure data is not used - in fact I have already done this. However when smoke enters room you don't just put a towel under the door and forget about it. I want to find the source of this and stop it because the behavior is not normal.
I agree something like zone alarm would be good. You should be able prevent or track an app activities for situations like this. If I knew what was connecting to these IPs and enabling the data connection I could stop it and report the app or submit a bug request. Right now I am just all alone.
I did try system panel which seems like a nice app but it does not give me good information on network usage by app. OSMonitor is better at connection monitoring but doesn't list by app. Why has no one thought to monitor network threads by app?
Try alogcat maybe? Any time you notice the icon suddenly appearing, save a copy of the logcat and comb through it.
alogcat may work. Figured out OSMonitor had something similar and filtered by app.
Now I just gotta wait I guess. Still not enough info to relate to IP though.
You should know that the data connection setting isn't an enforcement for the entire phone. It only acts as a notice to applications on whether or not to use data in the background.
Developers are supposed to respect those settings, but they are not enforced.
There is a free program called Network Statistics which is no longer in the market. I will backup the apk for you and upload it so you can use it. It shows the amount of data used by each app.
I too had a data hungry app issue and this helped me solve it immediately.
I'm just at work ATM, so I'll do it this evening. (Almost midday now here in Australia )
Cheers,
Ross
@JCopernicus
I am aware of this which is why I want to track this problem down.
@Ross
That sounds great. I appreciate the help. Not sure if tracking data usage is enough since I don't think the app is sending a lot of data. But I am willing to try anything.
I should be getting froyo soon so maybe that will help as well.
This is what I do when I want to ensure I don't use Data. Go I. To wireless connections. Mobile Networks, and then access points. Create a new one. I usually call it No Data. The for the apn, I just make something dumb, like no.data.com, and then save. After I'll select that as my apn.
The issue is not about the use of the data connection. I have done this and can guarantee the phone cannot use any cell data network. The problem is an app is trying to use it anyway even when it is disabled. Even if you ignore that as a concerning activity the constant 3G searching reduces the battery life to a mere hours.
I appreciate the help, but my issue is not with how to disable the data connection. Its about identifying malware on my device, and tracking an app calls to a specific IP.
Again,k 3g doesn't mean data. 3g is also used for voice.
If you only want to use "2g" switch your phone over to gsm only through 4636 or through the menu where it says "use 2g only".
You will never see the 3g icon again.
If you wan't to be 100% sure no app is calling an IP, then do a factory reset. Install apps one by one, monitor them through the various options given in this thread already.
You will not be able to prevent an application from "calling home" unless you modify the app itself. Apps use the data connection provided to them by the OS however they see fit.
Every app you install has a permissions prompt that will tell you it want's internet access.

The Android "3G", "H", "E" or "G" icon denotes data. It may also appear temporarily when making the connection necessary to transmit MMS. It does not appear when the phone is using voice over 3G without a data connection.
Actually, this may be a T-Mobile issue - they just enabled the ability to do "pay as you go" data on ALL plans without a data plan, so they may be the ones turning on the ability to do data. You'd still need to authorize it in your browser, and I think it costs about $1/1MB so it is totally not worth it.
May be worth looking into because it wouldn't surprise me if their new "service" is screwing things up.
I am aware of 3G voice but the 3G status icon is related to data flow. I have had the phone since launch and posted this because this behavior is not normal. Even Google was perplexed by what it is doing. And as I said it is not constrained by the 4636 settings.
And I disagree that an app can use the network connection as they see fit. Rights are given to perform its intended purpose; anything else is malicious.

WiFi App interference?

Is it possible for an App to interfere with the WiFi connection? I've downloaded plenty of third party, torrented apps and I've been noticing that my WiFi will work for a few pages and then stop loading, throwing up an error saying "Web page not available" showing the little Android. This would cause me to disable WiFi and go strictly with 3G. Enabling WiFi later would help with a few more pages until it wanted to die again.
After I uninstalled ALL of my apps and unrooted the phone, I've noticed that the WiFi works again (so far at least). I still have the same 1 bar signal from across the house, but it isn't giving any more errors.
I constantly used task killer to free up memory, so I don't think those apps would have made a difference in the sense that they may have been taking up some bandwidth or the such.
Any clues guys? Thanks for any help.
Same
I have the same problem. I rooted and did the settings.db. My wifi will turn on and connect but 20-30 seconds later it just turns off on its own. I haven't unrooted it to see if it fixes it though.
How did you unroot yours?
Thanks
Like, I'm pretty sure that's just karma, dude. Harsh vibes from people like me that make software for a living reaching out and disrupting your chakra centers. And your WiFis.
That and using Task Killer in the first place. Not needed, causes more problems than it solves (and it solves almost nothing on Galaxy S).
I am in the same boat--just started noticing it today when I got home from work and turned the phone back on only to see I wasn't connected to wifi. When I connected to my network again I noticed the 3G icon stayed on the screen with the wifi connection symbol, where the wifi icon used to replace the 3g icon. After a little while, it was gone.
I have rooted and removed some of the AT&T apps but nothing else. I havent sideloaded any apps either. It usually take me a couple of tries to connect to my router (WRT54GL). Sometimes it also seems that my phone turns off wifi by itself.
I hope this isn't a symptom of the battery cover antenna. Does your WiFi signal show as weak in the strength readout?

It does actually turn off wifi by itself! I did the following last night and haven't seen an issue since. As a new user, I can't post links: androidforums.com/samsung-captivate/130163-wifi-connection-turns-off-when-sleep-mode-default.html
From androidforums.com:
By default the wi-fi setting is set to go to sleep (and use cellular data instead) when the screen is off, which will most likely happen while you are streaming music as well as other things. To change it so the wi-fi never turns off, go into the phone's menu -> wireless and network -> wi-fi settings -> tap the menu button and select advanced which has an option for wi-fi sleep policy that had been defaulted to sleep "when screen turns off". There you have the option to change it to "never" or "never when plugged in".
Did a little more playing around with it, finally had to reset my router to maintain any type of consistent connection after restarting the phone. One weird thing is that my old iPhone wasn't able to connect to the router consistently last night until the reset either--it has never had any issues in the past.
After the reset, the captivate did maintain a consistent connection--I browsed a few websites and streamed part of a show from my computer using Allshare.
This morning when I turned on the phone wifi wasn't connected so I went into the settings and looks like the phone had attempted to connect unsuccessfully. I clicked it again to connect and it connected without any issue and was fine until I left for work. The whole thing seems a little wonky, as well as it should automatically try to re-connect if it fails the first time if network is in range, or at least give you an alert.
I just set up tdogz suggestion above, so we will see if it helps.

Running into the same issue, I am positive it is a software issue. It only seemed to happen after I flashed my phone with the Odin One click downloader. Dunno if it is coincidence or not. Going to try clearing the user data from the recovery window to see if it helps. I also notices on the power widget, i cant control GPS from there, blue tooth as well i think.

Huzza! I figured my issue out, may be yours as well. Did you do the sideload hack with the settings.db? Turns out you need to change the owner of settings.db to system:
Code:
# chown system settings.db
After that, I was good to go. The logic behind this is that settings.db tracks more settings than just if you can sideload apps or not. I'm betting the system is trying to change a value in that file and it cant after the hack, so various systems fail.

[Q] Automatically change to mobile data is wifi data speed too low, like in BB

Hi.
Is there any way for our android device to automatically start using mobile data even if its connected to a WIFI network, like it does in Iphone and Blackberry.
There are times you go to a certain location and having used their wifi before, your phone automatically connects to it only to find out that no data is transmitting and you can sit there for hours not realizing your phone is disconnected from the internet whereby, in BB or iphone, the phone just switches over to mobile data and keeps you online.
Most apps available just toggle wifi on and off but none I've seen can keep WIFI connected and still use mobile data.
Any help will be appreciated
There is an option, that the phone only connects to wifi if there is a good connection (under wlan --> advanced )
Hope this helps.
Same problem (but inverse)
Hi everybody,
I'm facing the same problem, just inverse: when the phone "considers" the wifi signal "too weak", it automatically switches to mobile data (even if the latter are disabled), the result is the mobile frequently drop the connection in some places at home where the signal is a little less intense.
In my phone, the option mentioned by Marc199 doesn't exist (or isn't displayed)...
What can I do?
Is there a way to access "hidden" settings like the one mentioned?
Thanks for your answers!

I'm facing the same problem, just inverse: when the phone "considers" the wifi signal "too weak", it automatically switches to mobile data (even if the latter are disabled), the result is the mobile frequently drop the connection in some places at home where the signal is a little less intense.
In my phone, the option mentioned by Marc199 doesn't exist (or isn't displayed)...
What can I do?
Is there a way to access "hidden" settings like the one mentioned?
Thanks for your answerns!

Well, there might be a chance that HTC removed (or never implemented) this feature. I'm using a GPE ROM.
If you mean the developer options, they won't be any use to you.
BestSignal Wifi-->Mobile Data App
I just installed BESTSIGNAL on my **HTC ONE M7**from the developer of the same name (BestSignal).
It's the paid version but only AUD1.99 and it works well, simple yet highly functional GUI. However it was not compatible on my Google Nexus 7 (2012) nor my ASUS Transformer TF700T so be sure to check your device compatibility.
As a XDA newbie I'm not allowed to include active HTML links so the App URL extension is: details?id=com.eightythirty.bestsignal and the Dev's is: developer?id=BestSignal

Question Data connection is active even when on WiFi

Hi all,
I'm noticing that the data connection seems to be active even when on WiFi. Is there any option that I need to disable so that the phone runs entirely on WiFi. I looked in the developer options and keep data alive option is unchecked. Am I missing something?

Hi, just go into Wi-Fi Settings / Advanced and switch off tab (Switch to mobile data)
That's all.

It's enabled by default just to keep your internet connection stable when wi-fi has an issues.

It will re-appear occasionally. Even if you turn off the "Switch to Mobile Data" setting, the mobile data icons and wifi icons will appear concurrently on the status bar. This happens even when the wifi connection is solid. Usually the mobile data icon disappears after a few seconds or minutes on its own. I'm not sure if its by design (for MMS or RCS or something else) or if it's a bug. But you're not the only one seeing this. My colleague has an S21U too and he shared a similar experience.

I'm suffering from the opposite problem!
I *WANT* to keep mobile data enabled while connected to Wi-Fi, but the setting on my phone has no effect! When I turn on the setting, my phone will still ignore mobile data.
I verify this by connecting to my dashcam via Wi-Fi. The dashcam does not provide any internet via Wi-Fi, but merely allows my phone to view the dashcam output and stored files. But once I connect my phone to the dashcam, then my phone has no connection to the internet. I can't force it to use the mobile data at that point. The phone is not behaving as it should. My older phone, LG G6, is able to successfully connect to the dashcam and still access the data through the cell signal.
The S21 Ultra simply cannot achieve this. I have the T-mobile variant, in the US.
I believe this is a bug. Can you get this setting to actually work? Like maybe test it by connecting your phone to your Wi-Fi router but disconnect the modem from the Wi-Fi router?
I'll post a separate thread for this, because I think it's a bug and maybe others are suffering from it without realizing.
