Issue with downloading data on background by Android system - Android Q&A, Help & Troubleshooting

Hello,
I have HTC One M7 with Android Revolution HD One 36.1 and recovery TWRP 2.6.3.4 .
I was running it like this without any issues for more than one year. Only recently (few weeks back) phone started to download huge amounts of data. It downloaded few GBs during weekend. All these downloads are displayed as Android System in background.
I have tried to block it with firewall but to no avail. I have tried to perform factory reset, I have tried to reflash ROM from TWRP. But in all cases issue immediately started again. In the end I was able to reduce consumption by restriction on all downloads in background through settings. This way it does not download data on cellular networks, but it still drains all Wi-Fis I connect to. It also means that I cannot use most functionalities I was used to like autosynchronization of gmail, apps like viber does not work and many other small obstructions.
Does anyone have any idea how to get rid of this?
thank you

[Q] Market and Youtube problem

Hi Friends,
Few days a go as I was watching youtube videos for around 45 minutes continuously through the youtube app. The streaming suddenly paused and never continued from that point. I tried other videos but it kept on buffering (the circle kept on spining and nothing happened, as noticed on the leds of wifi router it seemed youtube app is not using the net but when i search for more videos the thumbnail do showup normally).
To over come this issue i tried reflashing. This happened when i was on the new HyperDroid_v4.0 with Pongster's MattedBlack v4.0 Surgeons which is amazing for battery saving.
I then tried reflashing HyperDroid_v4.0 again after formatting /cache /system /data /sdcard /emmc which wiped everything, but still no avail.
Then i again tried reflashing DarkyROM2 XXKH3 BASE (2.3.4) formatting everything but still no luck at all.
I even tried these flashing after Factory data reset selecting Format USB storage as well .
When i do the flashing everything else seems to be working fine as usual except the youtube playback and android market doesn't download, like i said for the youtube app, everything like searching the apps, browsing through apps details works fine except it doesn't download at all. It shows as if it's downloading but it stays as is forever.
Very sorry if same question was posted before this as i couldn't find like it.
I have been trying to fix this for 2 days in a row but still no luck.
Has anyone come across this same issue.
Please help.
Thank you very much in advance..
Update:The problem was finally solved after again formatting /cache /system /data /sdcard /emmc and flashed stock ROM though Odin and then I installed DarkyROM tool and then flashed DarkyROM2_KI3_Base ROM.
I will soon jump to HyperDroid_v4.0 with Pongster's MattedBlack v4.0 Surgeons again as it has superb battery life.
I will be updating you guys if the same problem persist.
Thank you all
Hello everyone!
Although I am not using GS2 (I have a Galaxy Note), I chose to post here because I didn't want to create a new post and I believe this is not a device-specific issue (see below for why).
I have the exact same problem as OP (as far as I can see). When I got my note less than a week ago, everything was working great. Then, last Friday I noticed that I cannot download anything from the market. After choosing to download something (both paid or free), after clicking "accept & download" at the permission screen, the screen goes back to app screen and market shows the app as "downloading..." with working, yet empty, progress bar. Everything else using the internet works fine - browsing from different browsers, notifications, email etc. I even tried installing an alternative market app, and it would download/install apps no problem. Also, downloading straight .apk files works as well. Later that evening I also noticed youtube app doesn't work - just the "loading" circle keeps running, until it times out. Browsing/searching market/youtube works without a problem. I am using the stock ROM and it isn't even rooted. Later, following some suggestions from google searches on the problem, it turns out that downloads work when I disable network and let it use mobile internet. I also later found out that it works on other wifi networks, just not my home wifi (which used to work perfectly, with no configuration changes to the router).
Next day I also found out that my girlfriend's android (LG Optimus Me P350) has the same exact problem, therefor it is not a phone model specific problem.
Here is what I tried so far:
Factory reset - left me with no apps and no way to re-download them. The market download did work ONCE after the reset, but that was to download the update to the market itself, nothing else;
Clearing Download Manager data - worked for ONE download. At first it worked for one download every time, meaning, after clearing download manager data, I was able to download one app, after that it would go back to the problem. I could then clear data again, and it would again download one app. After about 5 apps downloaded this way, this solution won't work at all anymore;
Force closing/clearing data of market, gmail, talk (in combination with above step) - didn't work;
Signing out/in to gmail and/or talk - didn't work;
Changing google account in market - didn't work;
Stopping/starting download countless times - didn't work;
Switching wifi on/off - only starts downloading briefly when phone switches to 3G while wifi is off. As soon as it gets wifi connection back, the download stalls at the position it was until I switch wifi off again (so it can continue to use 3G);
Switching phone to airplane mode, off/on, then disabling airplane mode - didn't work;
Changing phone's DNS records with an app to OpenDNS - didn't work;
Updating router firmware - didn't work;
Resetting router firmware - didn't work;
Setting port triggering on router for port 5228 - didn't work;
Port forwarding to Note IP for same port - didn't work;
Disabling router firewall - didn't work;
My router is Linksys E1000.
I think that is all I tried. I have been trying to find a solution for the whole weekend, and nothing as far. Searching google makes me believe that many people have had the same problem. I have found many solutions, which don't work, or only work once. This problem is really, really irritating. Also, I have found out that for many people the problem seems to randomly disappear without doing anything after some time (days to months), sometimes coming back and sometimes not. I experienced this myself when after going to sleep, I was able to download one app in the morning with no tried "fixes" at that time. This also makes me believe that there are many "fake" solutions, which did work for some people, but not for others - quite possibly, while these people were "solving" the problem, it actually solved itself, yet because the person did something, he/she believes that was the solution. A notable example of this could be "google account 24-hour reset" where users experiencing the problem are suggested to log out of their google accounts everywhere and not use the account for anything for 24 hours. Seeing as this is possibly a problem somehow connected to another device, not just the phone itself, I did consider flashing DD-WRT on my router, but I wouldn't really want do do that since my router is not that powerful and with all the DD-WRT features my broadband speed gets capped at about 65Mbit/s. Still a lot, but I have a great internet connection and am able to get real speeds of about 90Mbit/s with stock router firmware.
If anyone has any ideas, please share Thank you in advance!
Just a quick reply - I contacted my apartment building network tech, and he said that they didn't do anything regarding the internet that day, but they did however do something to offer TV service to residents (edit: The TV network shares the same hardware as internet's). He said that it shouldn't have changed anything regarding internet, but he would look into it. A few hours later everything is working.
Of course, it could be one of those cases where the problem disappears with no apparent reason, but I guess they did something to fix it. So, if you are experiencing the same problem (market downloads not working and youtube app not playing videos), and you have tried everything else (preferably confirmed the problem persists on someone elses phone), I would suggest you start going up the chain to whoever is managing your network (after yourself). If at all possible, try getting wifi access through someone else who is using the same ISP/network - if the problem persists even when connected to another AP/Router, it's pretty sure the ISP or network is to blame.
Hope this helps someone, since I wasted a few days on this

[Q] Apps won't Download via data

Recently I have noticed that I am unable to download any apps from the play store or similar stores without having to be connected to WiFi. I have had my phone for about 6 months. Its a ZTE Avail 2, rooted running a few xposed modules. I only recently decided to get a data plan on the phone and the first time i tried to download an app it never got any further then the predownload bar. It never shows any percentage even if i leave it sitting for a long time.
I can download small items like documents and pictures but that's it. I attempted to clear the download manager and play store cache with no progress. I tried doing an internet speedtest and it gives me an error when it attempts the download test.
Is there something im doing wrong? I would love to be able to use my phones full potention and not be tethered to wifi to download apps. I was hoping somebody could help me. Thank you in advance.

[Q] I can't send/receive sms or calls until I reboot.

Hello folks. Been lurking on the forums, grabbing what info and software and tips I needed for a couple years, but never had a need to post something. Now, the problem has been described already in the topic title, but I'll elaborate.
Somewhere in a period of 24-36 hours of being turned on continuously, my phone (a Sony Xperia Go with Cyanogenmod 11 running on it, but the problem was there before with stock rom too) needs to be rebooted, else I can't receive or send text messages or call. The text messages simply won't be sent and I don't get a waiting tone (or any sound for that matter) when I try to call and it'll eventually fail.
Now when I still used a stock rom, I'd see that I had lost network connection, but on the current Cyanogenmod build I still have full bars. This issue I then have to fix by rebooting my phone, as I stated. I have not tried setting it to airplane mode for a quick fix, but in all honesty, I'm looking for a permanent fix, not a temporary one. And this also seems to be an issue that isn't just with my type of phone.
I tried looking for a solution already several times, but all I could find that described my problem was this thread. I have not tried ordering a new sim card from T-Mobile yet, since that costs money over here in the Netherlands, and I wanted to make sure I had exhausted every possible software fix before trying to fiddle with hardware.
Hope this is enough information for you guys to at least tell me something. Even if it's "yup, you're boned."
Gentle bump. Apologies for doing so, but I'm fairly certain I'm not the only one with this problem.
I'm having this same issue. I'm running the latest stable build of CyanogenMod on Maguro (CM11/Snapshot7). I push my SMS's through Google Voice (using CM Voice+ which is now integrated into the systems menu). I didn't notice exactly when the problem started because I have Hangouts and SMS integrated in the Hangouts app, and chat with people using both all the time. I do know that The problem didn't start after a CM update, it happened in the middle of the day while the phone was on as far as I can tell. Since then I have tried clearing caches, updated to the newest nightly release, and so forth to no avail. Rather than rebooting, I can just turn on airplane mode and turn it off to get my SMSs, but still quite a bother.
Did OP figure this out?
Nope. I ended up having to get a new phone, as it was getting worse and worse, up to a point where I had to reset it every hour. I just assumed it was a hardware problem and got a new phone.
I did a factory reset / complete reinstall and still have the problem.
After the reset and recovery, I assumed it was a telephony issue and messed with the APN and data settings as much as I could, including checking and editing the default databases. No avail.
I uninstalled Google Voice and turned off Voice+ and SMS's began working with my SIM number. Bingo! So I started messing with Google settings. Log out, log in. Reinstall apps, etc. I eventually discovered that whenever I tried to clear the cache on my Google Play Services my Settings would crash. So i figured that I had a corrupted Google Play Services, which was preventing my phone from syncing with Google Servers except on reboot or connection refresh. I later realized that I should have been tipped off to this by the orange wifi/wireless icons in my Settings dropdown.
I couldn't uninstall or update Google Play Services so I just downloaded the latest version of CM GAPPS, cleared app and Dalvik caches, and flashed GAPPS into place.
Bing, bang boom... it still didn't work. Icons still orange, Google Play Services still crashes when I try to open it from Settings>Apps.
Not sure what to do next except maybe another factory reset, and instead of using Titanium Backup to restore, I will just load a fresh version of CM11 and not update it. ??

[Q] Android OS chewing through half of my data plan?

So I have a Samsung Galaxy Young S6312, rooted and running on stock ROM(jellybean 4.1.2).
I don't have access to unlimited data plans, so I want to keep my data usage to a minimum. So I downloaded 3g watchdog and tracked what was using up my data. And I came to know that Android OS is using up about 50% of my data. In 2 days I used about 90 MB data, out of which 45 MB were chewed by Android OS. I also used Onavo Count, which showed me that on a day when I used 25 MB data, 18 MB was used by Android OS. Please suggest me a solution, this is driving me mad.
P.S : Auto-Sync is turned of my device. I have also turned off Backup of passwords, contacts etc. Also, I don't use Google+ or YouTube on my device. So I don't know what is causing this.
There's a bunch of suggestions here:
http://androidandme.com/thread/android-os-crazy-data-usage/
Unfortunately, there is no ONE fix as different people have the issue for different reasons. Sometimes it's because they're on ICS and there seems to be a bug that affects some phones with it. Sometimes it was syncing, which I know you have off. Sometimes it's Google Play Services. Sometimes it's a 3rd party app or built in stock browser or launcher that reports as Android OS. So yea...seems like a PITA. Maybe running something like this: https://play.google.com/store/apps/details?id=com.shaddow.eventLogger combined with this https://play.google.com/store/apps/details?id=com.mobidia.android.mdm might help shed some light?
If you root, there's firewall apps such as droidwall and afwall which give you control to decide whicch apps should have access to 3g, wifi, including android os, kernel and any system app.
I forgot to mention, I already have a firewall(Android Firewall) enabled, and I use it in whitelist mode, and I have not ticked any app to have internet access other than which I use. I have also not ticked Android System. Yet somehow, inexplicably, Android Os is eating my data.

I use Droidwall for this purpose, now no unwanted data consumption by apps.

OP already mentioned he is using a firewall and hasn't helped.
To that end, maybe trying using it in blacklist mode and check everything, just to see if anything changes?
Tried Blacklist mode today, banned all apps except the ones I use often, but to no avail.........
Why don't you try another rom? See if the problem persists then...
Are you tethering your internet to a computer?
Back when I had Verizon, I hacked my Motorola Droid Razr Maxx (4.1.2) to have free mobile hotspot. I noticed the same thing: that Android OS was using a ton of data. However, the math didn't add up. I had 4gb of data, but when I'd get an overage warning, I'd look at all the numbers, and mobile hotspot and Android OS added up to way more than 4gb. I concluded it was just a glitch, since it was hacked, caused because the software just didn't know how to report it accurately.
For example, I'm currently using a 4.2.2 Samsung phone on T-Mobile (unlimited), and I've used a proverbial #@%$ ton of data doing USB tethering with PdaNet+, yet PdaNet+ doesn't show up as using data. My billing cycle resets on the 7th of each month, and loading up the T-Mobile app, it says I've used 262.66GB of data. On my phone however, it says that I've used 474GB. But Android OS only lists 68.65MB. With my Verizon phone, I used wi-fi tethering. On my T-Mobile phone I use USB tethering (and some Blu Tooth as well). So that could explain that discrepancy, or it could be the different Android versions.
Either way, OBVIOUSLY, something is wrong with the way Androids track data usage when it comes to tethering. If you tether, my advice to you would be to actually add up everything listed in the data usage, and then compare it to what your provider says you've used. I have no clue what it's like in India, but in the US, every major provider gives you an account app that, among other things like payments and plan changes, tracks your data/messaging/minutes usage. If tethering is the culprit, go by what your provider says, NOT by what your phone says.
If you don't tether, I don't know what the heck the problem could be.
Well, that certainly explains a lot. I DO use tethering rather a lot, so I guess the amount of data I use on tethering shows up as Android OS. Thanks for explaining this out to me.

[Q] S3/Note2: GCM on Cyanogen completely stuck, no notifications

Hey,
I'm suffering some issues with two Samsung mobiles, namely a S3 and a Note2. Push notifications simply won't work reliably on both devices (lacking a data-capable SIM, I could only test on wifi, where other devices work like a charm).
I flashed with M9, then went to nightly, flashed the most recent GApps, and also tried push notification fixer, disabled wifi optimization, re-logged in via Hangouts, to no avail. Without a visible pattern, one or both devices fail getting GCM messages at all. Moving the device to airplane mode and back seems to newly roll the dice.
Wifi on those devices work, as I could ping them reliably, it's just GCM that doesn't work, visible in apps like Threema, but also in the Android device manager that is unable to locate the device, or the Play store when I remotely try to install an app. Putting the device on (unlocking not required) seems to cure the problem for a little while.
Having researched a bit, I'm quite clueless. As both devices IMHO are the same Exynos platform, and have been cleanly installed just a few days ago, is that maybe a known issue, related to Android 4.4 and wifi drivers?
Any chance of debugging GCM to see where the issue is?
Thanks!

Are you apply or modifying anything to do with battery saving?
Have you tried reseting to factory setting, wiping /system and /data (warning you will lose all data so backup). reinstall rom gapps plus those specific apps that don't work and tested it?

I did so before installing the system, both devices are a completely fresh setup, incl. wiping of system and data. I thought I had luck with wiping cache & dalvik as it worked yesterday, but today, once again, only one of those devices works.
Seems in fact GCM loses connection on one of the devices (the second one seems to work like a charm now). Removed Google account and re-added it, but status in *#*#426#*#* shows google play failed connection ev:1 err:16 net:1
No idea how to fix that though ;-(
If you have done a complete clean flash and not touched any settings im afraid im out of ideas.
