Problem with auto switch between GPRS and 3G/HSPDA - Galaxy S III General

Hi,
I seem to be having issues with my S3 (on 3) where if it rolls back to GPRS when out of 3G/HSPDA coverage it will then not switch back again when I enter 3G coverage.
Has anyone heard anything similar, more with the phone than the network in question (Three)? I recall hearing one of the phone support people mentioning that this was a known issue, but can't recall if it was this exact problem.
Anyone?
Thanks.

3g Tmobile UK Connection Issues

I(m currently switching between GSM and 3g - however i gprs seems to work fine for browsing however 3g does not seem to be working for browsing but ok for calls!! Im in the birmingham area where 3g coverage is normally superb - is anyone experiencing similar problems or know a possible way to resolve? I soft reset doesnt resolve the issue!
I am in T-Mobile UK and have no problems so sorry cannot offer advice - is surfing with GPRS OK? I have found T-Mobile customer support very good - give them a try. Their tech support people seem to know what they are talking about which is nice too - much different to O2. Good luck
PS - if not tried then take a look at the excellent plug-in by Daniel Herrero here. I doubt it will fix this problem but it saves lots of battery power and is very configurable.
I have exactly the same problem. 3g is really slow for surfing and GPRS is so much faster. In fact a lot of the the time on 3g I just get error messages saying the page is not available etc but if I then switch to GSM it loads in a second.
I have found something weird though: If I switch the phone off or go in to comm manager and switch the line connection off then try to surf or download on 3g it will not work.
If however, I switch the phone or the connection on then switch to gsm, and then to UMTS/3g it will surf on 3g.
For this I use Daniel Herrero's excellent program to fast switch.
but even this method sometimes doesn't work.
What I've resorted to is surfing on GPRS and when I need to download something, quickly switch (using Dan's Program) to 3g.
Am I right in thinking the no 3g connection after being switched on is a known issue with the Hermes?
HI JPHCCFC
Im in Birmingham on t-mobile and for the past two ...three days i to have had trouble connecting to the web or msn...very slow or no connection
Gavin
cheers for the info guys - im thinking that maybe its a 3g network error in the area - anybody who isnt experiencing problems in the birmingham area with 3g Data?
still no data 3g in the birmingham area....or is it my handset??? Gav1n how is your data 3g performing?
Im in manchester and i seem to have the same problem with 3g being much slower for browsing than the standard gprs
I'm getting the same issues in East surrey
phoned customer services they said they had no reported errors with the 3g network! they said try the sim swap with another tmobile sim to see if its the handset or network!
hi im still the same no 3G ....in brum (quinton) when i change the band to gsm every is thing is ok....its the same on my wifes phone ...so deff a t-moible thing...

3G connection issues on TMobile-Vario2
Dear all,
Appears the south-east also has the same type of connection issues. Everything appeared well until about 7-10 days back.
I e-mailed T-Mobile support and they advised that there were some network issues which could have impacted the service. I did notice that their on-line account services had also been upgraded around the same time period - maybe a coincidence - but every since then the phone doesn't seem to surf properly on the 3G service. AND, battery life goes down dramatically - I only now manage to get about a day's use out of the damn phone!
I've got a replacement battery from T-Mobile - but same thing happens. I think it's all inter-related!
So what's the solution anyone? 'cos I am getting rather hacked off with it all!
I'm getting hacked off with really bad now.
My grps is faster than 3g. Period. Regardless of reception. Anyone got a solution???
try disabling hsdpa with hermes tweaker and reboot your phone.make sure you are not connected to gprs while disabling it. it has solved my problems.
3G connection issues on TMobile-Vario2
Same here in the Canary Wharf area for the last 7-10 days. First I blamed my radio rom - I have upgraded to 1.34.00.10 when the problem started. But then I have also tried 1.27 and few older ones - all the same problem. Fast grps, but no 3G. The battery also dies quite fast on 3g, so I have now switched to GSM only. :-(
Don't know if any of you have done this already but I was having the 3G problems for a couple of weeks and battery was draining quickly, I phoned up T-Mobile and asked them if HSPDA was turned on on my account which it wasn't, since they turned it on the problems have disappeared and my connection speed is now at least 750 kbs.
3G issues
i have had my t-mobile for over a week now, but in the shop they said there was no 3G in edgbaston, birmingham but when i got it home i connected quite easily
3g dns failures
I have had a t-mobile vario 2 for the last 5 months. when I first got the phone I was excited to get the hsdpa activated and quickly phoned up tmobile and got through to a tech guy who activated it. I didnt really notice much speed improvement and tmobile only shows the 3g and not the h for hsdpa, but I was pretty happy with my speeds of around 70kbit/sec (tested through http://text.dslreports.com/myspeed?jisok=1). I downloaded fieldtest_157 which showed that I was connected to hsdpa but the values showed through hsdpa cqi status were very low.
About 1 month ago I was suddenly unable to go online whenever my phone went into 3g mode, my phone would show it connected but wouldn’t find any addresses. I was only able to when it switched to gsm. I phoned tmobile to get the problem fixed. they said it was a known issue with the phone and made me permenantly switch my phone to the gsm network. I was basically told that my phone does not support 3g and hangs on switching from gsm to 3g for no apparent reason and that they were working on the problem. they must have done something on their side because when I switched to phone back on to auto network switching, I got gsm and 3g connectivity and downloads but not hsdpa (checked with fieldtest_157)
next day because I was unhappy with the download speed I phoned tmobile and asked for hsdpa reactivation. the first level who answered made me hang on and reactivated hsdpa. same problem cant download except on gsm switch. rephoned tmobile and got through to another 2nd level tech guy and explained all my connection problems.he said that my phone had never been hsdpa connected and connected it for me. what do you know Im suddenly getting 950kbit/sec speeds and hsdpa cqi status shows all high teens or 20's. for some reason my battery is lasting allot longer and 5 months after getting the phone Im happy. moral of the story is to download fieldtest_157 from:
http://wiki.xda-developers.com/index...e=Hermes_Utils
and check hsdpa status because either lots of bull is being told to tmobile customers or there are some pretty stupid people working there.
I was getting lots of dns failures (except in gsm) and getting really fraustrated. I was going to ask for deactivation of hsdpa. Luckily the technician I spoke to (about the tenth person in 3 days) that eventually got me connected, new his stuff. He tried to trick me into admitting that I was using my phone as a modem for my computer and only connected me after I denied it. after he changed something on his side, he made me pull out my battery and do a soft reset. Everythings now how I expected when I bought the phone. It might sound like conspiracy theory but I got the feeling that he only connected me when it sounded like I knew slightly more than the average Joe. My hsdpa connection has been faultless ever since. Getting consistently high speeds even with 1 bar. On 3g!!
I had low fieldtest numbers before my proper activation. now all much higher teens or twentys
keep phoning tmobile until the problem is fixed!! and speak to someone who doesnt have to read a set of respone instructions and has some real knowledge.
Hope this helps
Cheers craig
No 3G in Glasgow. Was fine until 7-10 days ago. Phoned T-Mobile and the guy said they knew of problems. Asked for HSDPA to be activated, he claimed to have done this but no difference. Another post implies that they might not actually enable HSDPA first time of asking.
I bought the phone for 3G. It clearly has nothing to do with the handset since it worked fine for 3 months. Can I make a claim against T-Mobile?
i activated HSDPA and this resolved the issue for me!

More 3G woes in Glasgow

3g has been up and down a lot in the Glasgow area. Right now, I can connect but not actually do anything while connected to 3G (GPRS is fine). Can anyone else in this area confirm that 3G is not working? Is this a Glasgow thing or is it happening throughout the UK?
Bobby
Do you mean specifically for Tmobile or any 3G network in Glasgow?
Have you spoken to Tmobile about this?
I'm down south and having problem recently at my home address.
I mean specifically T-Mobile.
I must say, I am unimpressed with T-Mobile's fast data service. Their 3G service is down most of the time and they are reluctant to enable HSDPA even when you ask them to.

Hi
I use my Vario-2 connected to a laptop daily on my commute between Stirling and Edinbugh. Some days it works brilliantly, most of the time its so-so and sometimes it wont work at all!
Its a t-mobile issue, but they wont acknowledge it or fix it. They just keep asking me to provide them with 5 reports of it not working properly incl postcodes (which I do) then I hear nothing.
One thing I find all the time is that disabling HSDPA fixes many of the issues. Basically, HSDPA does not work well when I am moving. I notice this with downloads which may run at 70KB/sec when in the station, but as soon as th train starts to move they drift away to nothing. The phone does not switch back to vanilla UMTS soon enough when HSDPA stops performing properly.
I now run with HSDPA disabled except when I am stationary.
I wish there was a way to disable HSDPA without having to soft reset the phone for the enable/disable (of HSDPA) to actually take effect.

[Help!!]I can't hook up to HSDPA with my Kaiser anymore....

Hey guys, My device is Kaiser(TyTNII) and AT&T is my operator.
I live in Philadelphia, US.
Before yesterday my TyTNII can access HSDPA (with "H" symbol on the top right) when I try to use internet.
However, I use Kaiser Tweak to change some setting of my device and suddenly my kaiser doesn't recognize HSDPA network anymore, I mean it will only show "3G" on the top right. I have checked all the settings and everything seems fine.
HSDPA function is checked and same as in the Kaiser Tweak.
Can someone help me out here?
Thanks.
i have the same problem, cant go into hsdpa or even 3g only edge. and it seems to have happened after using kaiser tweak also.
Got some help over in the Kaiser forum that helped me. Go to your comm manager then settings/phone/ then go to band and switch your network type to wcdma. after it updated the network i switched back to auto and it seems to be working so far for me. hope this helps you out, something you could try.
I seem to have the same issue but the above solution doesn't help. Whenever I set the phone to do HSDPA through Connections I loss all data connectivity, once I turn it off HSDPA I get 3G.
Is it possible for radio settings to survive a hard rest / ROM upgrade or is the HSDPA side of my Tilt broken :-(
Any insight or help would be real appreciated.
Several times I have gotten "Warning: Unable to change GSM/UMTS Band, Please try again later."

OK is it possible for this to be tower related? What I mean is I drove about 4 miles from my house, got a better signal and surfed the internet using HSDPA. Now I'm back home and HSDPA is chocking and giving me "unknown error 0x80072f78"
What He!!?
One note on my HSDPA trouble, it must some how be related to the one tower nearest my home. When I go anywhere outside a 5 miles radius (I live near the tower) everything works fine.
Here is the weird part, every where else the phone will switch from HSDPA to 3G to Edge and back no problem. Here in town it locks into HSDPA and refuses to switch to 3G or anything else. I don't know if it means anything but it seems to get an IP address I can ping but I don't get any DNS info!.
Now how can I convince AT&T that there's a problem when their support person denies there is any HSDPA services and I should only expect 3G?

[Q] Poor 3G to 2G handover

Hey there, I enjoy reading this forum but I had little to contribute with as I am an android noob. So unfortunately my first post is a question forced by the fact that something is wrong with my DHD Thank you in advance for your advices!
The problem is - when in areas with low 3G coverage the phone keeps on searching for 3G for too long instant of seamlessly switching to 2G, which often has full signal bars. This way the phone acts as if there was no signal and sends incoming calls to the voicemail even though all it has to do is to switch to 2G as soon as 3G gets too weak.
My previous phones had no problem with this. In my city the 3G quality varies from area to area but the 2G coverage is perfect almost everywhere. So I used to be sure that my phone never really disconnects from the network, it only might have dropped the 3G signal in favor of 2G while keeping the calls and everything.
I know I can disable the 3G and stick to 2G and EDGE but this way using full data capabilities of the phone turns into pain instead of pleasure.
Just to make sure and to show I did my homework, this is NOT:
- the death grip case
- a network related problem /I suppose.../
- a problem with data connection /I have never run into any problems with this/
My questions are:
- is anyone of you experiencing this?
- is there a way to force the phone to hand over the connection from 3G to 2G quicker without "blind spots"?
- does any custom ROM improve this? /I am running the latest stock HTC DHD android 2.2 with Sense/
- is there any hint that android 2.3 gingerbread should fix this issue?
Thank you, hope to find a piece of good advice here!
I`ve found this service menu and I switched the preffered network from WCDMA preferred to GSM AUTO PRL. will see if it helps.
I havent noticed any more problems since I did the switch. I think it helped. I cannot be 100% sure but I think it did the thing for me. I forgot to mention that I also switched networks mode from Auto to European but I think this has nothing to do with the issue.
fortuneman had my answer. To access the service menu on the soft phone keypad enter *#*#4636#*#* and its under Phone Information.
Switching from 2g to 3g works seamlessly. But the other way around doesn't work that well. Nothing to do with the phone. Just the net tech that has its flaws. If your in a call and switch to 2g, the call will most certainly be disconnected.

[Q] 4G LTE Handoff to 3G Issue (Sprint - LS980)

Sprint LS980
Looks like most of my issues have been solved so far with this phone except for the fact that sometimes when a call comes in (or sometimes even out) the hand off between the 4G network to the 3G network is either very slow or doesn't take place; as in I get missed calls with a full signal or the phone gives up and makes me roam even though I have a full Sprint signal.
Anyone else have this issue or could offer any advice on a fix for this?
Are you aware of this?
http://s4gru.com/index.php?/blog/1/...-due-to-circuit-switched-fallback-technology/
Unfortunately I have read that article before. It does look like all of the towers in my area were upgraded last month and the service bulletin confirms this. Wasn't sure if anyone else was experiencing a hand-off issue; doesn't seem to be there when I set the phone to 3g only...
