[Q] Defy 3G auto enabling (set to use 2G only)

Hi
I have set data connection to "use 2G only" - because in my location i have weak 3G signal, and switching between them is draining battery fast.
But - almost every time when i reboot phone, and (i think) sometimes even without rebootin - it keeps to start using 3G network again - and set is still to "use 2G only"
Do you saw this before?
another funny thing - today my alarm didnt go off.... I was almost late to work :/
i heard that there was some problems with milestone and its alarmclock - can it be happening to Defy too?

Maybe your problem is connected with data delivery and management , is your phone data and background data enabled , whem its updating widgets like facebook and youtube it connect to 3g and updates the widgets information or at least so i think
once my alarm also didnt worked and the phone was 2 days old , it was just bought nothing changed and installed.... really bad and i got late for work

Yep, I have the same thing but after 5-10 minutes it becomes 2G only (2.34.1 CEE)

Galaxy Nexus loses network connectivity after enabling data

Build: IMM76I
Baseband: I9250XXLA2
If I don't enable data, the phone works fine. I can receive and make calls just fine.
Once I turn on data connectivity, data works fine for a while. Like 40-45 seconds. After that, the connection sort of gets stuck. I cannot make any calls, and if I call my number, I get a 'not reachable' message. The indicator in the notification bar will show full bars for a while, then if I got Settings >> Wireless & Networks >> More >> Network operators to do a manual search for network, the status bars drop to zero, become an 'x', and then go to full again. The behavior then repeats.
Bootloader is unlocked.
Any kind of help will be appreciated.
If it helps, I have the NTT Docomo version of the Galaxy Nexus (SC-04D) that is sold in Japan, but I live (and use the phone) in India.

Are the APN's set up properly for your carrier?
I'm assuming you've tried the usual toggling of airplane mode and rebooting, etc.?

APN is setup correctly, which is why the data connection works fine for a minute or so.
Toggling Airplane mode often does nothing at all, since the cellular connectivity system seems to be stuck, even when it does, it takes a loooong time for Airplane mode to get enabled in the first place, and disabling it takes even longer.
Rebooting the phone fixes the issue, but it returns very quickly (within a minute or so after rebooting).

Also, another similar thread over here mentioned that their problem got solved by flashing the FuguMod kernel - http://forum.xda-developers.com/showthread.php?t=1438417
I flashed the kernel successfully, but the problem still persists.

Mine is doing the same thing. I'm out of ideas.

i'm starting to think this problem is extremely common.

[Q] Galaxy nexus dropping internet very often

I have a galaxy nexus
ROM : XenonHD 4.2.2 (tried Stock 4.2.2 for 2 weeks)
Baseband : 19250XXLJ1 (was on earlier ones as well)
Kernel : Stock
Location : Bangalore(India)
Connection : TataDoCoMo
My internet (primarily using 2g, sometimes 3g) and it drops very often.
To enable it, the below steps does NOT word:
1. Toggling flightmode
2. Restart mobile
Only one step works (75% success)
Manually search for network and select network automatically and sometimes to manually select the network.
Please help.

Update: (Strict 2g mode enabled)
I've been sitting in my seat since posting the previous post. Checked my internet and i do not have data connection. Gonna enable it now.
Even manual selection of network dint give me data connection after waiting for 5 mins.
Enabled and disabled flight mode - waited for 5 mins - no go.
Gonna restart and check - last option - no go.
Now i disabled data - strangely, i lost signal for a few second.
Enabled data again - waited for 2 mins - and walah it came.
I dont know on what basis the internet comes and goes like this. It is not humanely possible to do all these steps, just to get the internet enabled. Can anyone help me from this plight.

Can anyone please offer some advice?

You can change rom, and check if it will be fixed.

What kind of network strength do you see in “Status“ page in settings? Post a screenie.
Try a different ROM to be sure it isn‘t a network fault.

Final solution to my data drop issues

I tried a lot of methods and this worked finally. Am on latest radio release I9250XXLJ1. Browse and install it if you are not on it.
Dialed *#*#4636#*#*
selected "Testing"
Selected "Phone Information"
Scrolled down and set the option of "Set preferred network type" as GSM auto (PRL)
Noticed change in GSM Service, GPRS service.
Next time, this dint work tried the below method and finally worked.
At the bottom right corner, the properties option indicated by 3 perpendicular dots took me to change Radio Band.
I tried with the first 5 option with no network coverage and finally AUS Band started giving me uninterrupted data signal.
Success...

[Q] [SOLVED] Intermittent Mobile Connectivity

This is a repost of a post made in the wrong forum: http://forum.xda-developers.com/showthread.php?p=41965120#post41965120

Hi all
A search of the forums revealed 5 potential threads similar to this but not quite (not same symptom, phone, modem ...)
Keep loosing mobile data connection...
I have installed X-note 3 and found that my mobile internet is intermittent particularly in Youtube where I frequently have to click "No connection , Retry" or "Connection to Server lost, Retry" and in Play Store and Gmail where the problem tends to occur on a screen unlock after it has been unused for a few minutes - about 3 to 5 mins.
I dont believe this is a ROM issue because I d/l various ROMS such as Revolution, Alliance, PacMan, Paranoid and still I get the problem.
I tried installing all 9 of these radios here: http://forum.xda-developers.com/show....php?t=2044937 to no avail.
Also notice that if I set Network Mode to "GSM only" then this makes no difference to the problem (the default is "GSM/WCDMA Auto" which is what I've set it back to)
WiFi works fine.
Any ideas?

same issue here.
a lot of time trying to know why this happen. and i think it is due to fast dormancy.
the phone usually stays in standby in 3g... when you request some data it will automatically turn h or h+. Here is when you will notice the internet moving.
But unfortunately if you have some.coverage issues you can have this problem and then the programs instantly report no conection. If you insist you will see you can obtain connection. 5 seconds later 3g will appear again
It does not mind you will see the bars of coverage at maximum... if there is no quality signal you will have this problem.
I just have this problem at work. Not in other places.
But if you want a constant connection I recommend to keep for example online music while navigating...this will avoid the issue...unfortunately you will increase your data plan..

Yes!! This is exactly what happens.
So it can't be my specific phone but perhaps a hardware design or software issue. I don't recall this I happening before I rooted
Weird

Fixed it - so far at least
Fast Dormancy is the problem. It was enabled by default and I have turned this off. The connection is now fine and seems to be "always on". For me this is okay because I do not have any data limits or pay per MB for data. I do notice that new connections take a little longer to start (for example, time taken to access internet when opening up an app that is not currently running) . This is not noticeable for apps already running (in the background)
This explains ....

[Q] No network data connection

Hello all,
I got my P6 for a few days and from time to time I had troubles to connect the data network (2G and 3G).
When I switch the data on, it connects to the network for 1/2 seconde and then it disconnects (the H+ symbol stays on though). Switching the data off and on again only repeats the problem.
Restarting the phone allowed me to finally have a stable connection so far but since this morning it doesn't work anymore. Removing the sim didn't help.
I'm on B125.
Anyone encountered this problem and managed to solve it?
Thanks!

I may have solved the problem.
Use tweakker from the play store to get the exact apn details for your carrier (mine is Base Belgium) and put them in the apn settings.
Since that I can connect the data without any issue (except a new bug: switching to "2g only" make the connection bug again, except if the data is switch off before and switch back on after a dozen of seconds). It seems that it is more like a carrier problem but that creates bugs only with Huawei products (source: internet).
It seems that the P6 is a very capricious phone, I love it but I wouldn't recommend it to anyone which is not an engineer!
