Hello, I recently flashed CM 10.1 on my Note 2 and the mobile data seems a bit weird. For instance, when I enable the mobile data, it connects quickly and perfectly. However, after about 10 to 15 minutes, I don't know why even though it said to be connected (you can see the 3G/H+ icon and the signal bar was in blue), when I try to refresh a webpage or use services that require data connection, it fails to retrieve data. However, after I turned off and turned back on the mobile data, it works perfectly fine. This doesn't bother me allot as I do not leave my 3G idle for long time, but I still wants to know why and to see if there is a way to fix it. Thanks.

I have a reoccurring issue of losing cellular signal whenever I run applications that use a constant GPS and data connection. For example, I use Glympse almost daily, and I find that after 10-15 minutes Glympse reports "no data connection" and my 4G LTE symbol is replaced with the no signal (circle w/line through it) symbol. I cant get phone calls, texts, data, nothing. This seems to happen with any app that uses GPS and data like Glympse, Google Maps/NAV, Navigon, etc. If I use an app that just uses data (Pandora, Sirius, etc) with no GPS the connection is solid and I have no issues. I am able to get the connection back by turning on airplane mode then turning it off again. If I just leave it, the connection never comes back, until I turn on airplane mode or reboot.
Has anyone else seen this issue? Hoping that a fix or ICS comes out in the next couple months that will resolve this. Between this and the screen issues I am thinking about taking it back when the Note is released and seeing if they will let me swap it out.
I’m currently using AOKP Jellybean 4.1.2, the supposedly stable, reliable milestone version found here: http://forum.xda-developers.com/showthread.php?t=1804223
I'll try to be as thorough as possible in hopes that someone will respond and know what to do. I apologize in advance for being long-winded.
I didn’t have any issues last night when I first flashed the rom. I was able to watch youtube videos using the mobile data. I was also able to turn on wifi to sync some files from my dropbox to my phone, and then turn off the wifi with no issues. However, today after connecting to a wifi network to download a few things and browse the web, I disconnected from the wireless network and the mobile data curiously did not start up again. I DO have cellular service (3-4 bars), and I can make phone calls and check my voicemail by pressing and holding 1 on the keypad, but my mobile data doesn’t work. I looked around for some solutions, and I've since restarted my device several times, tried toggling airplane mode on and off, and did several combinations of reboots with airplane on/off and no dice.
Everytime I use the toggle in the notificaton bar area to turn off wifi, my internet connection goes with it. It says “no internet connection” in the notification background at the bottom of the screen. Once I turn wifi on, I get my internet back and it says “at&t” at the bottom, but I don’t actually get mobile data because apps like “At&t Visual Voicemail” which require mobile data to function don’t work.
I tried flashing the 1.85 radio to see if it would connect to mobile data, and same issue persisted after reboot and dalvik/cache clean. After that failed, I flashed the 2.20 radio + RIL zip files seperately (which is what I understand came with the rom), and still no dice.
For reference, my HTC One X was rooted with 1.73 firmware (I never tried to update it until last night). I did the CID spoof method to unlock my bootloader, and installed the newest version of TWRP on it. I flashed the rom and the gapps package. I used TiBu to restore program settings and a handful of my out of market apps, and the rest of my purchased apps downloaded automatically from the market after connecting with my google account. I had literally just finished reinstalling the last of my apps today via wifi when this issue started to happen.
I'd really prefer a practical method of getting this fixed that doesn't involve starting over with a fresh rom install. Reflashing at this point would be something of a nuisance since I don’t have much free time to begin with. And hey, it took a long time to load up all of my apps just right
However, if there is no other fix that anyone is aware of, I guess I could reflash or in the worst case try a different rom. It’s a shame because the rom otherwise is really smooth and runs great on the phone, in addition to not using a whole lot of resources and having a decent battery life.
Thanks in advance for any suggestions and solutions.
Here is an image of my battery drain screen showing what my mobile data is supposedly doing despite not being able to get a true data connection. Even with my wifi off, there is supposedly medium mobile signal.
And attached is another image of what happens when I turn my wifi off. I pulled the notification pane down and you can see that it says "no internet connection" at the bottom. Also, you can't really see it in that cap, but the mobile data bars behind the notification area are colored white, and there isn't any "H+", "4G", or "LTE" notifiers visible.
Edit: Attached a third image showing the "white" signal bars (i.e. no data connection). Yes, my mobile data is turned on, and I'm obviously not in airplane mode.
I figured it out eventually for anyone interested... Apparently the APN were not set. They existed on the APN list but were not visible due to a glitch in the ROM I guess. I had to add a custom APN and then the other ones suddenly appeared.
Thanks anyway.

On certain ROMs, such as Cataclysm, my data signal goes away after disconnecting from the WiFi. But this has been happening on several other ROMs, too, and I can't seem to find the reason behind it. In case it matters, I'm using my phone on Sprint, data works fine with the stock ROM, and problem starting occurring more often after the 4.4.1 update. Any suggestions?

What you described looks similar to my problem.
I’ve been flashing 4.4 and then 4.4.1 ROMs on my Nexus 5 since I’ve got it early November, but I have not updated bootloader and radio up until yesterday. This week being on Slim 4.4.2 beta 1.5 I couldn’t connect to mobile data even though I had 4 bars and it was showing 3G or H (no LTE here yet, at least for me). GPS was fixing my location on Google maps, but navigation was not able to recalculate the route and was not moving my position along the way. Only when I switched from navigation to map, it was showing me as moving accordingly. Maps also couldn’t search for the address I was looking for. Now I realize it was a data connection problem.
So I thought it’s because I’m using 4.4.2 ROM on 4.4 bootloader and radio. Yesterday I downloaded Google 4.4.2 factory image and fastboot flashed all (efrant, your guide is irreplaceable!), formatted cache, did a factory reset and all. I wanted to have 100% factory state device. What a surprise today morning, when I realized I have no mobile data. Orange 4 bars signal with 3G or H. No internet though. Rebooted – the same: max signal, no internet. I turned Airplane mode on and off. Signal is back and I have internet, but bars still stay orange. So I rebooted. No internet on full 4 orange bars. Airplane mode switch on and off – mobile data regained, yet still orange.
When I reached the office I turned on WiFi. Got strong WiFi connection, bars went white, both WiFi bars and mobile bars (in Quick Settings). I switched off WiFi – mobile data is not reconnecting, staying orange, showing 3G or H. Sometimes it’s coming back after few seconds, sometimes it requires switching Airplane mode on and off to bring it back.
WTHell?
I was never putting much attention to mobile data because at home and in office I’m on WiFi, and while driving I’m listening to audiobooks so I don’t see what’s going on with mobile data. Sometimes I take a train, and then I’m browsing xda – I don’t recall having connection issues in train up until recently. But what I recall now, for some time, when coming back home and turning on WiFi, email notifications were popping up immediately. Does it mean I had no mobile data and phone synced only after it had WiFi?
This is annoying and driving me mad. Do I have to fastboot flash 4.4 factory image to see if it’s gone on 4.4?
Any ideas what can I check before going through factory img flash again?
Does your data eventually kick in after a few minutes, or are you without data for an extended time after disconnecting wifi? I know with Cataclysm if you enable Smart Radio it takes some time for data to ramp up after disconnecting wifi, although I'm not sure about how other ROMs handle this.
I'm on full stock 4.4.2 now, just roorted with SuperSU 1.80, no mods at all. I wanted to check if it is related to custom ROMs or general.
It's random, after switching WiFi off, mobile data sometimes comes back after minute (rarely) but more often I need to switch Airplane mode on and off to bring internet back, but even this does not work all the time.
Mobile toogle shows 4 bars with 3G or H in orange colour (screen attached) when there's no data or there is data. Never goes white for mobile data (I remember it used to). Now it becomes white only after I switch on WiFi (2nd screen attached).
Hopefully it's not this but I've been seeing more and more people starting to experience it. Mine started acting up slowly and then now it's having the issue in the thread linked below.

I've seen this thread, but my problem is different. I'm not getting the "emergency calls only" message. I can call or receive calls without problems. It's mobile data which can't reconect after switching off WiFi, even though mobile signal is strong - 4 bars and it's showing its on 3G or H. And Why it stays orange even after it finaly regains mobile data?
Almost since I got my nexus 5 last year it has been loosing its connection about two times per day. It does this in three different ways.
1. total loss. The little outline of a triangle appears and a notification that I have lost my connection. Clicking the notification opens the manual selection of networks. I select the network and all is fine.
2. full connection with an exclamation mark. solves it self by waiting for a while.
3. full connection with H/3G but when trying to access the internet there is no connection. This one is really weird. The solution here is top open the quick settings, select flight mode, which greys out the connectivity triangle but keeps the H or 3G part white on top of the greyed out triangle that has a slash over it. About a minute later the H or 3G disappears and I can turn off aeroplane mode. This either restores the connection or jumps to problem one.
First I thought its a hardware problem, but since I don't want to part with my phone I never sent it back to google for fixing.
When android 5.1 was released I installed that manually and surprisingly did not have any problems at all after this. But then I went abroad and using the same sim connected to a local network in the country I went to. It took 4 tries to join one of those networks. When I then came home this problem started again.
My thought is that there is some setting that should be there that stayed from my trip. I have tried clearing all caches from the storage in settings and the dalvik cache. No difference. I'm not to keen on re-installing my phone again. So my question is, has this happened to anyone else? Did you solve it? Is there something I can do to remove all previous settings for the network to make it work again? Other suggestions?
This happens to me, at least 4 times a day for me, it has only been doing it since I installed 5.1 on my nexus 5, which was a brand new one from Google since I smashed my screen and they just gave me a new one, I'm in the UK btw, not sure where you are but it does take forever to connect to mobile network when I turn wifi off too.
I constantly lose connection at my house going from E to H+ to LTE throughout the day

For me it happened before 5.1 as well. But 5.1 fixed it temporarily, until I travelled with my phone. Have you had to switch to another network with that phone?
For some reason when manually looking for a network it seems to be running on a timeout function because it takes me 60 seconds to get the list, always. This feels like a very antique solution, they should just populate the list as a network is found like wifi does it.
Hi,
I'm using a Sony Xperia Z5 Dual Android 7.0 facing that issue making me unable to use my WLAN hotspot (which it pretty anoying cause it doesn't only dissallow me to share my internet connection but also I can't do other network stuff between devices I'd use that hotspot for).
So when I try to turn on my the hotspot it simply turns itself off again after small amount of seconds. When I got to WLAN hotspot in settings then I have the active button to switch the hotspot on while it shows me tbat it's of at the moment. Doing that it says "Activating hotspot..." (pretty exactly that) until it's going off again with a quick "Deactivating hotspot" and you could activate it again but it will do nothing again than say "activating" and go off again. While it is "activating" it already shows the active hotspot icon in the top bar of the phone and the hotspot settings are as well already active and no more inactive greyed out. But only for nk idea, 3 seconds probably. Within that short period of time my laptop didn't find my phones hotspot but that might just be down to an to high delay in scanning and finding so I don't know wether it would shortly pop up seeable for other devices.
Earlier that day I had my hotspot working actively (nobody actually joined) but it worked and would have if somebody joined because that issues is not new to me on my phone and when the hotspot activates, then it also works. But half of the time it seems when I want to use it, it doesn't work. I haven't changed any settings inbetween or restarted my phone. It was probably on for one week, but after then trying a restart it still didn't help.
I already changing some one-click stuff like just turning out WLAN, turning off or on data save mode (which stops background data for all apps in mobile internet and WLANs marked as hotspots), turning off or on mobile data. But well, I don't know anything else and earlier it worked with all the same settings so what could be the problem behind that?? Besides that my phone always just works completely normally without any issues, WLAN always works without problems, only Bluetooth sometimes doesn't want to activate and then I see it active after some minutes or hours later, but that can always be fixed with a restart if I needed it instantly. If you just wait and it is active then tough, it is kinda awoken and works instantly then again shutting it off and on.
Phone is not rooted btw.
Ok long text, but please if you have any ideas tell me..
