data network problem - Mate 8 Q&A, Help & Troubleshooting

I have an app of voip which will always run in background. Here's the problem:
The phone is using lte data connection to internet. The network comes to be unreachable for the app after a while when i put the phone in screen off mode. I have set trust the app, granted all privileges that the app requested, power plan to "Performance" ... nearly everything possible. It seems that the phone "blocked" the internet communication of the app. I can see the app is running background and trying to send packets but got network unreachable from the app's log. But at the same time, the explorer works fine after I open it. To let the app could use the network again, I have to manually relaunch the app by click it's icon.
any ideas ?

What firmware version are you using? This sounds very much like the problem I had on B168. If I'm not mistaken, versions prior to B170 suffered a problem with connectivity for background apps. Like I could never use WhatsApp Web on my laptop because the app on my phone kept losing connection.

A couple fixes for some of our problems

Lets face it. All devices have bugs upon release that the normal person won't care about nor think of it as a bug. This device has it's share but as a reminder. There is no software bug that can't be fixed. By the way, make sure you don't skip the initial setup and if you did just wipe and restore.
1) Some are having a problem when using WiFi. There 4G or 3G data is not turning off and instead of your device using WiFi to exchange data it is using your 4G or 3G data. If you turn WiFi on and don't see a 4G/3G icon in the notification area then your device is working properly in this department.
The Fix: There is three "My Account" apps on our devices and there causing a conflict when 2 or more is running at the same time. To fix this you need to delete all of them (I used Root Explorer). If you use "My Account" you can download the current version from the market. Next, freeze or delete WiFi calling and the T-Mobile app pack. After you have deleted everything you have to reboot your device. Note: While deleting or freezing some of these, you might get some looping force closes. Just simply remove your battery to reboot the device and once it reboots the force closing will be gone.
2) Some are having a problem when moving from cell tower to cell tower. If you are losing a data signal every once in a while but the 4G/3G icon is still showing in the notification area, you need to do the fallowing.
The Fix: Go into your Mobile Network settings and make sure your device is setup to automatically use GSM/WCDMA. Then click on search for networks and at this point you will see T-Mobile UMTS, T-Mobile GSM and ATT GSW. After they appear click on select automatically. While your at it go ahead and click on data roaming since T-Mobile has contracts with other providers so your able to roam on there towers. Don't worry, you won't be charged for roaming since T-Mobile only charges for international roaming. After all this do a reboot.
Some of you think that there is a problem with your battery if your device is showing your "cell standby" above 30%. This is not a problem. Every time you charge your G2X it will reset usage percentages as you know. Well if you emediatly start using your phone and don't put it down for 2 hours than I promise you that your display will be at the top of the list. Obviously if your device stays off for a little bit and upon waking it you look at your battery statistics your going to see Cell standby and Phone idle at the top since the display was off. If your wandering why Cell Standby is using more juice than WiFi it's because when you turn your display off it automatically sleeps your WiFi.
The percentages in your batter statistics need to add up to 100%-105% and something is going to use more than the rest depending on what your doing with your device after removing it from charge. Ask yourself this. If my G2X is in my pocket for 1 hour after removing it from it's charger. What would I like to see using most of my battery? I can tell you right now. Certainly not your display since it's been off the entire time.
There's only one MyAccount app on the phone. I looked myself in the System/app folder. If you see multiple MyAccounts in a task manager it is just another instance of the same application.
Also there's NOTHING wrong with Wifi Calling or My Account. I have both on and use them extensively. My phone has gone now 26hrs without a reboot or hitch of heavy usage. Wifi works, 3G/4G works perfectly. I don't have any issues right now...until the next reboot
Want to give people another perspective since you don't have to give up MyAccount or Wifi caling to have a usable phone.

Thats WHY you don't have any problems. Because you only have 1 "MyAccount" application. Those of us that had 2 or 3 have the problems. By the way I had 3 and no they weren't showing in task manager. They were all deleted using Root Explorer.
Where did you see them? They were all in system/app??!?
Odd how they could all exist together - were they named differently?

Yes, different version numbers and branding included in the apks. I had 2, version 1 and version 5.x.
OP, for some reason when I try Search Networks I get: "Error while searching for networks." Any ideas?

They all existed in the system folder. It seemed like instead of the new versions updating the existing app, they were just creating new files. Your right, it is odd but I can see how that would create a problem.

Hello, I have recently started having the same issues with my F6 not being able to load any background data as well. I believe your solution can lye within the apps that are being used. I Use a stock ROM too for my phone as there are no others out yet for it, and so, I also use ROM toolbox. This morning i could not for the life of me remember what i was doing to make the phone function this way, but remembered that i was dabbling with the DNS and server operations on ROM toolbox the night prier. I was a bit frustrated that there was no easy answer posted anywhere online (google) and had to figure it out myself.. (not so bad) . and since i have been constantly figuring out my ROMS abilities on STOCK I have acquired much knowledge for the F6 root and recover operations. IF you are having problems with any data being transmitted between apps and have been disabling ads through ROM toolbox be sure to make the right changes. For when you wake up to having no data app connection and your clearly connected to the internet it can become jarring.
hope this helps

[Q] Force app to use WIFI only

How can I force a specific app not to use mobile data but only WIFI?
My use case is:
I like reading news through Play Newsstand, but it uses up way too much data for my plan... I would be happy to let it sync every night through WIFI and then just read the stuff from yesterday, without it constantly pulling new stuff using tens of MBs.
Any way to do that without using flight mode every time??
Thanks!
Disable background data on the app
Settings > Data > choose app then restrict background of said app.

I looked at that already, but for example today I see 25MB of Foreground data and only 5MB of background data, enough to make me think that the effect of that flag would be minimal.
In fact, the most data is downloaded while I use the app rather than in background.
Anything else I could try? I am also rooted.
Hmm, Xprivacy (xposed module) may work although I have never personally used it. But from what I have read about it, it restricts app data etc. Give it a whirl and see perhaps?
The play newsstand app has it's own setting:
'Download via Wi-Fi only'
Does this not work as advertised, or am I missing something?

It does not unfortunately
That flag only controls how data is synced in the background, but my problem is when I actually open the app to read the news. In that particular moment it starts downloading all news (and images) for the feed I open every time, and that generates tens of MB of mobile traffic.

you could get a firewall program (maybe you'll need root for it), and block it from accessing 3G (but allow through wifi)
then use tasker to turn on wifi when you are using the app. this way, the app will never use 3G

Thanks for the suggestions.
I could try both, but waiting for Android 4.4.3 to install Xposed.
If any of those can do "Prevent app XYZ from using mobile data" then it's fine.
Xprivacy could be a better choice as it doesn't sound like it's going to use up as much cpu/mem/battery as a firewall.

i'm using Xprivacy... XPrivacy isn't completely foolproof either.
there's an option to block "internet".
In android, you can call "isConnected()" function to check if you are connected, and then not do anything. XPrivacy overrides that function and can return "false".
however, apps can "ignore" or not use those functions, and just force it's way to connect to the internet. it can still succeed (you can test to see if this happens)...
firewall shouldn't be using a lot of your CPU cycles...

Could you suggest a firewall app in particular, considering that I don't need advanced functions at all, but merely the bit to turn mobile data off?

Lol 'Download via Wi-Fi only' is a misleading setting!
Another possible way, xposed and 'App Settings' module, could also prevent internet access I believe, but not sure if it can specifically block mobile only.

FYI, AFWall+ seems to work just fine!
I will also maybe try Xprivacy when 4.4.3 comes out and I will install Xposed.
So far, happy with the firewall approach, might come in handy for more apps that I want to prevent from using up data when underway.

Something are turning on data transfer

Hello
I am using latest .93 firmware and i have noticed strange thing: something are turning on data transfer and then disable it.
My data trasfer is turned off, after disabling i hide the notification "data trasmission in cellular is turned off" but after some time when phone is inactive the notification appears and seems that i got charged by using data.
The monitors doesn't show any info which app using data transfer.
Are You experienced this ?
Is there any way to check logs which application enabling data transfer / how to block it ?
Seems even if i block cellular data for any app the connection to network is made and few kilobytes pass through.
Do You have any ideas ?

I don't have that problem at all I'm on 33.2.A.2.93 myself, is the background data turned off for each and every app go to settings data usage and click on each and every app in the list for data+WiFi and set the slider at the bottom to the on position. The notification you get to say that data is disabled that looks like a small globe will come and go on its own anyway usually when you wake up the xa it's how it is it doesn't mean it has actually used any data it's to remind you it's off
Have you also turned the Bluetooth+WiFi always scanning for connections Inc when they are actually turned off. Go to settings location and tap the three dots top right turn both sliders to the off position.
This should stop any background data being used and won't effect the way any of the apps work

+1 sometimes !
The bluetooth, wifi, cellular(agps) location helpers are OFF.
Trying for now not to disable all cellular data(the switch to block all traffic) because i am trying to indentify app that cause problem.
I get used to manually turn on and off cellular data and would like to keep that way with this phone.
'thing' that turn on data make me nuts.
"small globe notification" appeared once in last half day - t-mobile app says usage of 200kb but Data Usage Monitor does show nothing
I think that issue depend on signal strength.. Always when back from basement which is located underground i had that notification about mobile data.. Also in forest, when signal is gone or rly poor.
But had no idea which app is responsible for that. Also trying few times turn off notifications in random sys apps and nothing so far..
The beggining of the end...
The telegram app shows notifications too, strangw notifications, why? The app is not listed on the detailed ps list, is not running anything related to telegram, ate least the unrecognized service that poped up the notification.
This is new method they are using.
Is not online, but the notifications is poping up.
Called as Multidex odex(or dex from the app) and cached secondary-dexes provided by them when we last tine was online.
We ended and closed the app, but, the secondary dexes are in the Memory opened
Someday i was searching why my apps are all closed , but the ram is sluggy and filled?
This is why.
Preventing yourself agains these new kind of apks before installing.
This may contain virus.
This is destroying the cpu and the ram.
These secondary dexes processes are hidden, and unkillable (unless i root and forbid services)
Nothing is turning on the data.
The cached dexes are running in hidden background, showing the notifications that was not readed when was the app online.
This is a serious damage menace.
I disagree with this, after i discovered this, now, i am denying packages with Multidex inside.

I forgot to mention:
Imagine:
I am running a newsapp, with fully adblock in action.
They will search a "V".
They creates a temporary secondary-dex, when my installation id is on line reading their news, the cached dex is , for exampling: deleting my pictures, uploading something mine to their servers, deleting musics, corrupting files, etc.
due to the secondary dex is updated periodically... on cache, free for do what they want do on my device...
They found "V" Vengeance
Because i am Ad blocker
Only because this.
This is why the RootCloak was created.
To hide root and commands that some apps runs in hidden background
I tried search how to forbid this Multidexes apps.
But untill now, the solution is
Not install.
Check the package before installing and read the Manifest.xml about the multidex version.
If no multidex tag found, is safe apk.
Remember the Quadrooter.
They may creates a secondary-dex for destroy the gpu easyly.

Yes, you are right! I have checked that.
That notification reappears when i lost signal and get it back. Appears also when i turn on airplane mode and then switch it off.
So nothing actually switch on cellular data BUT ...
i found what cause the problem
it's localization
I have it enabled BUT helpers are switched OFF (wifi+cellular) and bluetooth but it still using AGPS.
When i use app that use localization - for example speedtest app (using wifi) then localization icon appears and a moment later two arrows (up/down) appear on gsm signal.
so the question is :
How can i disable AGPS ?? (settings -> localization -> three dots -> scanning -> both options are OFF)
Please someone check if You have same problem (turned agps off and using app with localization and celular data disabled you get two arrows on gsm signal)
EDIT: The mode of GPS is: only device. Note that evey switch off and on it defaults to best accuracy.
When i make sure it's only GPS (agps disabled) and helpers are off and run speedtest with localization it STILL using agps
BUG ?
The OS itself downloads data too, even on rooted.
100 per month going where ?

Yes but android OS doesn't use data traffic when data traffic is disabled.
AGPS does
Solved
Problem was resolved by SONY's support:
Selecting device only will not disable assisted start on the GPS. It only disables location by WiFi, mobile network and bluetooth.
What you can try is to go to Settings -> More -> Mobile networks -> Access Point Names. Here check the APN type on all your APNs. If you have "supl" on the APN-type, try to remove this. Then turn off mobile data or connect to WiFi and see if it still uses the mobile network.

Apn type says - default, supl. But there is no way to change it.Its greyed.
I think the only way is to dissable 4g (when not using the phone or when wi fi is active) , and remain on H+, for me its free. And that way will not lose my 1 Gb quota.

I have exactly the same issue. When I clicked on the APN type, I got a free text box and I didn't know what to type in. In the end I deleted the APN. This obviously means that I can't use mobile data when I want to. This is very frustrating and seems like a bug. Please post if you find a solution...

Those apps probably read your cache instead of using online data, have you check your APN?
Chrome is one of those apps.
I use the APN which my mobile operator provides via SMS Configurations. Other phones in my home uses the same operator and same APN. But they don't encounter any issue.
Can I check it via ADB or logcat or whatever....?
I think, Factory Reset is the only option. But I have Bank apps. Factory Reset changes Device id. So I will be in trouble.
Thanks!
Are you using a VPN or private DNS service?
