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 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?

It was said that:
Carrier has FD Enabled + Phone has FD Enabled = Good
Carrier has FD Disabled + Phone has FD Disabled = Good
Carrier has FD Enabled + Phone has FD Disabled = Bad
Carrier has FD Disabled + Phone has FD Enabled = Bad
So what "bad" effects does it do when it is disabled and if your carrier supports it? anyone care to explain?
ex.
- does it make your battery life worse?
- does it make your data speed slower?
Been testing for days but didn't really see much of a difference. Either FD Enabled or Disabled.
TIA!
anyone?
battery saving as it allows the data connection to quickly turn off/on when not transmitting data
^you mean that when FD is enabled with carrier support FD right?

Yes, it would seem that way, you can phone your carrier to confirm if they support FD, and you can get fast dormancy toggle in play store to toggle on/off
In my case turning on/off fast dormancy has minimal, if any, effect on battery life.
U asked if globe supports fd.. but you dont even know the effects? -.- lol..

I think he is right to ask even if he doesn't know its effect. Nothing wrong with that.

Yeah i know it's a good question.. but it is unnecessary to make another thread. Overriding his previous thread would've lessen the redundancy of the FD topic and this could actually help out a lot of users
Again, nice question bai!

Hey guys,
I have BBB (Better Battery Stats) installed and saw that one of the alarms is causing a huge battery drain. Its caused by fast dormancy which should actually save energy. In BBB it is called com.qualcomm.fastdormancy. In my case the phone can not enter deep sleep when fast dormancy is active.
I found an article describing the problem with fast dormancy ([FIX][ROOT] Disable Fast dormancy on sony smarthphones) but unfortunately I was not able to disable it. The guide is just for Sony devices and I could not find the folder ./etc/fast-dormancy.
Anybody with the same problem? Does somebody know a different method to disabled it (except for editing the build.prop file because it could cause a bootloop)?
Thanks!
I solved that by rooting and then instaling Service Disable from playstore. Then disabled fastdormancy Service.

Yes this might solve the problem, but what fastdormancy do? And what are the consequences of disabling it?

Not sure what it does, but when I disabled it the phone felt laggy, now I re-enabled it and it is snappy again.
Sometimes, Play services cause the battery draining issue and sometimes Installing some faulty app and overclocking the device may reduce the battery life of your device.
There are common steps you can follow like using black wallpaper to take advantage of the AMOLED panel to save battery.Uninstalling unnecessary apps can boost your battery life
I just read some tips which are common but useful->>http://fixdroidbattery.net/fix-fast-battery-drain-problem-on-oneplus-x/
Hi,
I ran into the same Problem. Phone most time running @300mHz instead going to DeepSleep.
(Network Providor for me is currently SIM.DE - Sub Providor of O2 Germany)
This morning I found an article and disabled "Fast Dormancy" with the Build Prop Editor.
http://forum.xda-developers.com/xperia-l/general/tut-disable-fast-dormancy-battery-life-t2348597
Seems to work fine for me so far. Phone is going to deep sleep again now.
I changed this 2 hours ago, so I can't say anything about longtime use or potential other problems.
Anyway, I would like to share these links because there are some useful information probably interesting for some people.

Yes. For me situtation is much better now. There are still some dormancy wakeups but I think this is normal behavior and initiated through some apps.
If I doesn't use the phone much over the day, I get about 1 to 3 hours longer battery time.
I don't recognize any other problems or limitations, so for me the fix is perfect.
