When my phone shows the H symbol for network, it works well, but when I'm not using the network (no traffic), it falls back into 3g and gets stuck on upload. Occasionally, H service will come back, but often it won't. I have found if I turn the screen off, H service is restored.
I have had this problem for months now. I have a i9020a. Currently I have CM9 April 8th nightly installed, using the i9020AUCKJ1 radio. I just got done reverting to the stock build recently released from Google (IMM76D, I think), then upgrading to CM9.
No matter what I've done, nothing has worked:
1. reverting to stock then upgrading to a custom rom (Team-Kang, CyberGR, CM9, etc);
2. trying different radios;
3. opening phone info (*#*#4636#*#*) and changing it to GSM auto PRL as well as setting the band to USA;
4. making sure the APN is correct;
5. restoring the IMEI backup;
Any ideas what the issue could be?
H is 3G. Only active while data is being actively sent/received and it is actually feasible to use in your current area. Also, are you sure it is not only the animation that gets stuck?
Is there an actual problem, though? Is something not working quite right (data, sync, notifications, etc)?
It gets stuck on UMTS:3 (just keeps trying to upload) and won't work again until I turn off the screen and then it will usually revert to HSDPA:9.

you should download taskiller.. kill all app before you use your internet, i have same problem and always solved with that way..

While taskiller certainly kills most running processes, it does nothing to help my network connection.
On a separate note, my roommate has the same phone and his maintains a steady HSDPA:9 connection without ever dropping into a UMTS:3 connection.

The normal behavior of the phone is to use HSDPA while it's in need(download/upload) , when not in use automatically goes to UMTS:3
What ROM your room mate is using ? model ? radio ? network ?

You're talking totally rubbish ... Killing apps will not enhance anything and may even slow things down by needing more CPU power to open auto apps again...
I have expereinced the same issues with my 9020a on ATT. Sent phone to Samsung twice, changed SIM cards 4 times. Updated radios, now on 4.0.4 getting about 120 kbps download speeds while my other phone (work phone), iphone4s on att, gets about 5 mbps.
Call att, they credited me my entire months bill and offered a free galaxy note with a 2 year agreement. My thought is that ma' bell is just killing any unlocked phone or there are issues related to "LTE" rollout they wont admit to that is causing a disruption with 3.5G.
Anyways to the OP, you aren't alone. I too hope someon can help!
My roommate is using the same rom, CM9 (nightly from 3/29 though), radio is i9020xxkb3, network is also AT&T with same plan.
Watching the About Phone/Status on his phone, it stays on HSDPA:9.
My returns to UMTS:3 when not in use, but when in this mode, I get no network traffic at all. I will flash upload but will never download anything. Occasionally, H service will be restored, and I will get my network connection back.

Anyone else having a problem with the NxS jumping between 2G/3G network all the time?
I tried 2G-only and it seems the it does interrupt connection less often, but it still does. I'll exchange the sim card tomorrow to rule out the last option (I can think of) I got before returning the NxS and asking for a replacement.
(i9023, stock rom/kernel/radio, tried 3 stock roms with diff radios (KA3, KB3, KD1))
Maybe anyone got an idea or a hint.

Granted I'm not in the best 3G area, but I usually get 3 (of 5) bars in 3G and then it just pops back to 2G.
Might be network pumping (or w/e it's exactly called), gonna exchange the sim anyway to track down the problem further.

Hi guys.
I have been using my Atrix 2 from 4-5 months, and this is really an amazing phone.
But I found a thing really irritating.
The Data Connection on the Atrix 2 is very unstable, and it automatically gets lost if the phone is inactive for some time, say 1-20 minutes.
I have set the phone is performance mode, and have no justifications for this behavior.
I am on BSNL 3G in India, using APN BSNLNET.
Motorola Atrix Version: MB865
System: 55.1.27.MB865.AsiaRetail.en.03

Does anybody else have the same issue, or the solution to this?

I had that problem too I am on at&t 2g edge in the u.s the way I fixed it was I rooted my phone installed clockwork mod n I am now running rebelrom beta 3 with a atrix blaze update on top of that. Ummm if u have no intention of doing any of that then I would say u best bet would be call Motorola or ur service provider n ***** at them
Data connection stops randomly
I have too observed the same problem guys.Whenever there is low network signal it will switch off the data connection on its own but it will not start the data connection when there is sufficient data network available.
Some time I have to switch on it Airplane mode and after few seconds need to off that mode.If it won't work then the only option to start the data connection is restart your device.

Hi!
I'm using an Atrix 2 (MB865) from AT&T, Unlocked, Rooted, Original Stock ROM and i'm having the same data transfer problem with Movistar Argentina.
I think a good option could be to flash a new ROM, but it's hard to see all option we have.
From my point of view, i need an stable ROM with good battery life.
Any suggestions ? Supercharged could be the one ?
I've certainly had a lot of luck with Supercharged. Everything's faster and more stable...battery life is much improved. I installed AnTuTu's CPU Master and Battery Saver, and that's helped battery life quite a bit too, it seems. (I'm a heavy user, but in spurts, not constantly)
My brothers running Sonya v3 on his atrix and loves it. Its much smoother than stock and he seems to get decent battery life out of it. He usually does an 8-10hr day at work and he gets home with still 50% or so battery life.
Same here, running wifi all day. I do plug in if I'm going to use Bluetooth for anything, though.

For what it's worth, I've seen a lot of wifi problems lately. I was wondering if maybe those with issues might be restoring wifi settings with titanium or similar methods. My point is, back when I had a Cliq XT I remember this problem popping up often with various roms (cm7, superOSR, ASOPs) and the common denominator came down to restoring wifi settings often would break wifi. So, for those with issues, make sure you're coming in clean when you flash/restore, don't restore wifi settings.

Enabled PUSH DATA and with that in the settings,It does not allow the phone to turn its Data Connection off.
i wasn't experiencing this in MAH. but now i'm in bangalore & have this problem
i searched a lot and came at one solution i.e. to keep requirement under control
it means whenever you want to download, switch to 3G else for being online Edge is more than sufficient
it irritates but quite helpful
i use the app "network" from market to switch :good:
I have no signal when using 2g, but no problem when using 3g(hspa+, wcdma). I think this is a software problem because the mainland chinese moto Inc already fixed

I have been having this problem with both of my Nexus S 4G ever since I got them 2 months ago.
My data drops out frequently and takes a while to get back up. If I have 4G enabled, then I have to manually reconnect it as it will not do it on it's own. This happens inside AND outside. Driving down the road or just standing in one spot.
I've tried all of the radios (basebands) and about 7 different ROMs and versions.
I've refreshed the data profile, PRL, and even tried the roaming Verizon PRL and Hybrid PRL.
Gone back to stock and tried everything from scratch. Still the same problem.
Dallas/Fort Worth Area
Network: Sprint
Baseband: D720SPRKE1
PRL Version: P:40447
I contacted Sprint and they just told me to update the profile & PRL.....
Any suggestions?
I'm not familiar with the CDMA nexus s, but are you able to change APN's? At one point I'd be able to connect to 3g (I have an I9020A), but every minute or so it would drop, so I fixed up the APN's for my carrier.
iv had a few data issues
forcing PRL and account updates has fixed it a couple of times
i'v bought used phones that iv had
to have sprint force update
im on LC1
[altho i cant tell any significant difference here]
and my prl is 61086

im currently on slim
make sure your mobile network
is set to roam
is not set to home only
Am I the only one with this problem? As I'm typing this I lost data but still had 3 bars. I never drop calls but only data.
Help please. This is driving me nuts.

I almost always have to use 4G (if possible) since 3G speeds are slower than dial-up.
I've tried rebooting and leaving 4G off, and still the same. Even tried going back to Gingerbread.

I have the same problems. From what I understand, its a problem with the hardware. I can confirm that's probably the case, because I've tried many different ROMs (stock, cm, etc...) and they all have the same radio issues (3g/4g and wifi)...
I have an NS4G in the DFW area and haven't seen the issues you're reporting. I'm currently on 4.0.4 with D720SPRLC1 baseband. Maybe I'm just lucky and have a good signal at work and home. It's very rare that I find an area of DFW where I don't get any data signal at all. Not sure what to suggest.
I get random drops too and i hate it. My 3g speeds are fairly good even above 1 mbps. Highest i ever got on 3g was 1.51 mbps
Mine will lose data if I'm in a coverage free area for an extended period of time, when I'm back in range 3g icon will show up just never reconnect. A reboot fixes it
Certain Areas
There are certain areas where I live that data just disappears. Although this is just a network thing I believe. It's weird though when I am driving it's like a 10 second drop and then all is good. Hope you get a solid fix!:victory:
Backup 4g Partition
REMOVED - was a bad idea.
I've actually replaced BOTH of the phones with brand new NS4Gs and they shipped with ICS.
Still the same problem.
This is driving me nuts. I was driving and trying to download Maps for the new phone from the Play Store and it took 6 tries. Kept saying RETRY.
What I've come to believe is happening is:
When 4G connects, 3G disconnects. When 4G drops (which is does frequently), 3G has to reconnect.
***Is there a way to keep 3G "on" in the background while 4G is connected?*** Maybe a way for the radio to transition back and forth?
Hello everyone,
I hope someone can help me because I am going crazy with my Optimus 3D My device constantly loses the 3G connection and so I don't get any notifications about new e-mails and Whatsapp messages. The icons for network strength turn white and even sometimes that happens with the wi-fi icon. I already tried rooting the device and installed a custom rom but I still have this problem. The problem mostly occurs in the office I work in as 3g and network reception is very low here. I see that the device switches between HSDPA, GPRS and 3G quite often and then most of the time loses the internet connection. It also does not reconnect when I walk around and get to an area with better reception. Sometimes switching to Airplane Mode and back helps, but this is not a very handy solution. I am really clueless where the problem could be. I am here in Frankfurt/German so normally there should be no problems with the network (I am on Vodafone). The only thing I could think of is my SIM card, because I had an iPhone 4 before and had to cut the card to the micro SIM size and now use it with an adapter. Could this be a problem? Also the app 3G reconnect did not solve this problem.
Has anybody a clue what might be wrong with my device? I am already thinking about getting a new phone
Cheers,
Andreas

I don't know when it loses the connection, could probably happen when it turns the screen off or switches between network speeds (3G, GPRS, HSDPA). It really is a problem for me that it does not get the connection automatically back. Currently it shows almost full network reception, the "G" icon with both arrows underneath (only the left arrow pointing up turns green from time to time), but it has no internet connection. I sent me a mail to my google account via my office PC haöf an hour ago, but still no message on the phone, that there is new mail

I had similar Problems with O2 in Bremen.
That happens if the phone loses the 3g(h+) signal, turning of the data connection, and let that reconnect is enough, no need to turn on airplane mode than.
Try flashing the newest baseband version, and try the prometheus rom + kernel. I still notice that the same problem happens, but it reconnects again after losing it now, and i rarely notice it that way.
Maybe you could tell us your android version, and baseband version.

When I left the office for lunch it did not reconnect, so again I did not get the newest e-mails. Probably I will really try another SIM card with a different network provider. I never had this issue with my iPhone... Thanks a lot for the advices, hopefully something will work. Otherwise I need to get a new phone :/

For me the 3g data service goes as it likes but to reconnect i have to restart the my phone. Tried many roms as well as kernels and finally using acura 3d Max 3.1 with titan kernel solved the problem.

Hi all. I've had a search but can't find much on this. A friend has a bog stock Telstra one xl running stock jb. The data connection works fine except written she's trying actually download a file like a pdf attached to an email or an app from the market. When the download starts, the phone switches to hspa mode, as you would expect and then the download pauses before and data is downloaded and the phone switches back to 3g mode. The download never resumes. It works fine on wifi.
I've tried force closing the download and google play apps as well as clearing their data and cache. I've reset the apns to default. I've tried creating a new apn as directed by Telstra's config site. I've tried using different google accounts.
Apart from doing a hard reset, does anyone have any other suggestions?
Thanks heaps

Sounds like it could be one of two things.
It could be that when the phone sleeps (screen times out) it switches to a low-power mode to save on battery. (check settings)
Also, If the setting for WiFi sleep is set to always, it will hold a connection even when the phone has timed out.
Or, it could be your friends location. It could be right on the edge of having HSPA+ on the coverage map, thus the phone gets a low HSPA+ signal and switches to WCDMA.

Yes, the phone will surf fine on mobile data just won't download actual files. Everything works fine on wifi.
I've checked the apns against my razr hd on the same network. Some were slightly different so i changed them to match. No difference. I reset the apns to default. No difference. I setup the apns to the carriers specifications including a proxy. No difference.
I think she may have to do a hard reset...

The location makes no difference. I'm sure it's not that.
As for the sleep thing. That would affect all mobile data. But you can be surfing on the internet, find a file to download but then the download will pause straight away. So i don't think it's that...
Thanks for the replies guys.

Just as a further note. I just tried forcing it use the 2g network only and the same problem persists. It uses EDGE to surf but any download instantly pauses...

Yes, even in its own settings you can set a limit. But I'd expect a toast notification to alert you of that an not be able to surf.
Sounds like something missing in the apn yet to me but that's my feelings on it. My telus uses two, only carrier that does that I know of, I get ok speed on one but with second I get very fast speeds.

I've had a very similar thing happen to me as well. It's not restricted to downloading though, it happens while surfing too. So I initiate a download or load a web page or load a page on the XDA app, it switches to HSPA, then it will drop back to 3g and the download goes nowhere. Usually opening a web page (or initiating some other kind of data transfer) will switch it up to HSPA again and the download/web page will resume. It's not a constant thing, only sometimes.
I happen to live in a house with terrible Telstra signal and it happens mostly here. Like I said it's only every now and then for me though. Is the signal strength ok where your friend is?

No definitely nothing to do with location. You can have full coverage at the problem persists. My Razr hd works perfectly beside it and the one xl supposedly has better reception (blue tick) although I'm yet to see any evidence that the Razr actually has worse reception. It seems very good. Must have come very very close to getting blue tick too...
