Hi!
Is anyone else experiencing problems with the mobile data connection on this phone? It frequently stops working. Being in an area with excellent HSPA+ coverage, this can't be a signal issue.
The phone will suddenly stop loading anything, while displaying "3G" and an active upload indicator in the notification area. No internet usage is possible in these situations.
The only remedy: Cycling "data network mode" off/on. The phone will then immediately pick up HSPA+ again, working as intended.
My previous phone (Nexus One), which I used pretty much identically and at the same places as my Galaxy S2, did not experience these stalling issues. Is this a general (firmware) problem, or should I possibly look into getting a replacement unit?
I also have this problem. My SGS2 is on O2 (UK), got the phone from P4U.
Exactly the same problem, connected through H+ with good signal, suddenly the phone will switch to 3G and I will lose my connection, this can last for minutes unless I toggle data on/off. I am on KE7, but had this problem with KE2 as well.
It sounds similar to a problem mentioned in other threads, but this is the exact problem that I am facing.
I am also considering replacing the phone (if it is a phone issue, and not a firmware issue)
Happens to me also. Very annoying

Same problem here, but i also have problem with communicating via phone. Every time it starts in home, usually morning. I cant recieve any phonecalls or sms, also i cannot call or send sms. Need to reboot, signal is -113dB and i cannot choose plane -mode, it doesnt go there. Also i cannot select operator manually. Reboot is needed every time. This scenario has been over 3-4 mornings and i have owned SGS2 about 1,5 weeks now.
I have disabled fast dormancy, and never again experienced the issue.

I assume one has to be rooted to do that

Yes, I think he is referring to this procedure: http://forum.xda-developers.com/showthread.php?t=1086599
It's good to know I'm not the only one experiencing intermittent connection issues - as this appears to be a firmware problem, I will wait for Samsungs next few releases to solve the problem. If the bug won't go away I might get a replacement unit.
In any case, please report back - if someone got his phone replaced due to this issue, did it fix it? Any other possible solutions?
I've spoken about this issue, the 3g itself doesn't want to work.
I've tried uskr's fix and it seemed to have worked. Also root needed.
The fix involves editing /system/build.prop
adding to the bottom.
ro.ril.enable.dtm=1
ro.ril.gprsclass=12
ro.ril.enable.3g.prefix=1
ro.ril.hsdpa.category=28
ro.ril.hsupa.category=9
ro.ril.hsxpa=3
Happens to me, can't wait till it's fixed.
Same problem with my phone
Just to let u know guys i'm facing the same issue with this phone. My data connection disappears completely bringing up a circle sign. I also lose the ability to make or receive the call. I sometimes get calls going to voicemail with full reception, when this happens I can't browse either. I am debating whether to replace the handset as I have about 4 days left to get a replacement. I bought the handset from carphone warehouse. It is a sim-free unbounded handset running the latest KE7 firmware. Any help would be appreciated as i am absolutely in love with this handset. By the way could u tell me if anyone is experiencing jagged lines while scrolling in the browser.
That's something new.
Try factory reset.

Someone mentioned loading up the phone hidden menu *#*#9900#*#* and clicking on Disable Fast Dormancy there, but not sure if that actually works or not.
in another thread i have solved this problem on my device by disabling fast dormancy. not only it solved 2g/3g issue..it also solved lost connection and battery drain.

hello iznee,
so how did you disable fastdormancy ?
i tried the hidden menu *#*#9900#*#* but it didn't work.
or did you do uskr method posted about how to disable fast dormancy ?
what about the method of editing the system.prob ?
which one of them?
please clarify
and did that solved your problem about switching from 2g to 3g ?
regards
It's not really a 2g/3g problem, more 3g/HSDPA and up problem.
And there "could" be two fixes, one I mentioned above (editing build.prop) lets call it data fix.
And the other requires deleting or editing the actual fast dormancy file as explained here
http://forum.xda-developers.com/showthread.php?t=1086599
Both are actually uskr's fixes. I did the data fix, which worked, but to make sure, I also deleted dormancy file.

could you please point me to this file which needs to be deleted ?
i checked uskr thread and he crossed the part about deleting the file and only kept the part that involved editing that file.
sorry but just to make sure
Hi,
My Lg Optimus One stops receiving calls (calls go directly to voice mail) and texts at seemingly random times without warning. Restarting the phone fixes this problem, but only temporarily.
The problem started only recently while running the Void rom, and has continued since flashing Nessy #Hypnos only a few days ago.
Any help is appreciated.
me just have can't type any message
coz the keyboard won't come out to let me type

have you tried reflashing void rom?
It may be network problem. But if u don't want to reboot. Just select aeroplane mode and come back to normal mode.

No, I thought it may be a problem with Void so I instead flashed the Nessy rom (which changed nothing).

Toggling aeroplane mode on and off works as well. I suspect my phone may be faulty, but a network problem makes sense.

Also try, use only 2g network from settings,as phone tries to switch between 2g and 3g for better network.

I have recently switched to Oxygen mod for P500 (LG Optimus One) version 2.8 and am experiencing an issue similar to you.
From time to time (maybe twice a week), I attempt to use the phone to make a call and it does not work (call duration is 0s). I cannot receive a call either, or get voicemail notifications. Using data works correctly though. I am using the Telus network.
Switching to plane mode and back fixes the problem. But it is not a viable long term fix as I never know if I can or cannot be reached...

I did not have the issue with the stock Froyo firmware. I did not use the stock Gingerbread firmware long enough to confirm if the problem was present or not. I often use the underground subway where there is not signal, I have a feeling it might be related to the issue. I will attempt to always test if I have the problem before and after using the subway.
I started getting this error this when trying to access the internet.

Skyrocket or regular Galaxy S II?
Regular galaxy, just started happening this morning.
This just affects the internet browser, Firefox, ....
what are you running? stock or custom?
UnNamed. I did flash the in call volume fix. But did a nandroid restore this morning and am still having this issue. I will try wiring when I get back home.
I browse over wiring but not over the network. I can get me emails, weather widget updating, tapatalk, ect.
AT&T is probably having an issue in your area. Might want to call them.

I've checked with a few friends and they're fine.
-its not happening to other AT&T people in the area
-its happening to all browsers you use on your phone (?)
-reboot did not fix it
The only two options left, that I can see are:
-reflash the rom.
-call AT&T because maybe they need to reactivate your data on their network, unless its only internet that's being affected and not ALL data on your phone. This has fixed some data issues that I experienced in the past.
Make sure your sim card is seated properly and not damaged.

in that case, try reflashing the rom
Hi all,
I've had this extremely annoying problem for ages and I don't believe it's only related to the SGS3 (I had this on my SGS2 as well, probably should post in a more general forum but w/e) and it seems to be when I'm at work only so could just be confined to an area but constantly throughout the day my data connection just stops working.
What happens is:
Data working fine ---> I don't get any notifications for a while (whatsapp, etc) ---> Check phone and all I see on the HSDPA icon is every few seconds the upload arrow lights up then goes off, over and over...
The only fix is to restart my phone, I can try to switch data off then on but that takes a lot longer as the phone can't disable data quickly and turning it back on takes forever; same applies to trying to get the phone in Airplane mode.
I've only had this problem in Westminster but it's just so frustrating because it keeps happening over and over and I have tried so many solutions (new modem, new kernel, formatting various different areas of my phone) but since I started having this problem with a different phone I'm at a complete loss...
Any help will be very appreciated.
Thanks!
I've pinpointed the same issue (or at least one with identic symptoms) to 2 different problems
- one specific cell antenna had issues with fast dormancy, it kept forgetting the connection. Disabling fast dormancy helped somewhat but since the issue was on network-side it only really got better when they finally checked+upgraded the antenna (it was offline for half a day)
- my provider keeps pushing apn settings with a terribly slow and broken proxy.
Removing it brings the network to full speed. If you have no proxy configured or cannot remove it, try using a VPN network to see if it gets better.

I think it's the former, I've configured the APN myself before and it's still been an issue. I hadn't thought about it being the cell antenna, I think I might call O2 and inform them because it's so irritating.
Wish I could give you more than just a thanks!
Thanks!
Memory recalls O2 are updating to Fast Dormancy in the South .
FD toggle on off app now on the market .

Hey, thanks for the heads up. Should I just switch fast dormancy off for the time being then?

That happens to me,too.
And it lasts for about 2 months,seems no solutions yet.:crying:
One possible reason I got is like: every time the phone encountered a signal problem,such as Airplane Mode,weak strength,etc.The phone react much faster than the SIM card,and then the sim card is not really initialized,the phone itself resumes up,and got a wrong MCC/MNC,both are 000.
No solutions on photons yet,because there seems no one works on Photons' framework.That could be changed by correcting the framework I think,because same problem happens on so many types of phones,such as ST18i.And both are resolved.:crying:
You can fine more information on CM's official website,there are many discussions on resolving other types of phones.

Hello there, I´m using the phone in Perú in a GSM network, with stock 2.3.4 and rooted. So far my MoPho has never lost the APN configuration. Are you only losing your 3g connection and your APN? Because I do lose my GSM signal sometimes in a day, but for some seconds only.
Hi, I am in Sweden and I am using miui 2.6.1 ics rom and I have no problems also I use a app called apn global its a quick way to set up apn's it reads your sim card.
GSM apns disappearing
Hi
I am on Cm9 aokp build 38 and i also had this issue of apns disappearing ( I am in India using GSM) The solution is to flash forceroaming.zip files from cm9 fixes files in this forum and flash it and restart it. If you dont see any apns manually you enter the apn value of your provider and save the settings and voila the problem is gone:highfive:. Sure this fixes the problem but I dont know how:fingers-crossed:. experienced guys may help but i am experiencing uniterrupted data after this
Used to have the disappearing apn problem for cm9... but since recently flashing to cm10, the disappearing has stopped... In the "Manage Apps", i noticed that the apndormancy service was stopped by default for cm10...probably thats what stops the apns from disapearing when phone "sleeps".. If theres an app that can freeze services and you can get it to freeze the apndormancy service, i think this would stop the disappearing.
Cm10 all data problems have been eliminated apns don't disappear. For cm9 you can flash forceroaming.zip
