Diamond/o2 Germany HSDPA idle bug on HD? - Touch HD General

Tried the Diamond/o2 bug yesterday on the HD. With o2 SIM, HSDPA would disconnect every 30 seconds, and mostly not re-connect automatically. This happens while you are reading online, device waiting for your next input. HD icon also jumps from H to 3G after 30 seconds, but seems to stay connected. Pressing the next link jumps back to H. Can you please test this on your HDs?
With o2 SIM, surf to link in HSDPA mode, wait 30 seconds, see H jump to 3G, then follow another link - jumps back to H. I hope this is not indicating a disconnect, but only a speed pausing. After following another link the apperance of the next page seems to happen to fast to make me feel the connection was disconnected. Your views?
Update: Since spoke to o2, the fallback from H to 3G is a network "feature", and there is no disconnect on the HD.

A very interesting predicament indeed ie HELP

so here i go
i have just received my jasjar from SBE after them having it for over two month (complete morons over there dont EVER use then unless you are obliged to). got it back, worked fine for a week and now, it will ONLY log on to UMTS networks for example im sitting at home i have a U symbol and 2 bars signal strength. I go into phone settings and select GSM instead of auto and it stays searching for 10 minutes then says no signal, i can get it to join the network if i select manually my network but i can then make no calls or texts or log on to the gprs network. i am using pocket phone thingy for the today screen. and here comes the wierd part. when im out of signal in a non umts area the today screen plug in reports a signal strength ie 63% and above it it states attempting voice connection. and HERE THE REALLY WEIRD PART. i still receive my cell broadcasts when out of gsm signal. ie its searching and ill get a 'text' saying 0208, 01829 .
Please help and dont tell me i have to send it back to the idiots at SBE

using data connection during a call

im sure this usd to work, but recently ive noticed it doesnt. when im in a call, my data connection disconnects. normally this isnt a problem, but sometimes i will want to look something up on the internet while in a call. like i said, im sure this used to work, but now it doesnt. im on t-mobile UK with an unlimited data plan, i have a near full HSDPA signal. im running the CleanEX DsE v15 ROM with Radio 2.11.
any thoughts
should work on 3g, not on edge or gprs
don't be confused by the left hand network symbol showing an H, that's just what your network is offering. the signal bars icon must also be showing H
i have a H as the left hand icon, and a little h above the signal bars. when i start a call, the smaller h changes to a picture of a phone. if i try and use any web features it just times out. when i hang up the call, my data connection seems to have been disconnected, as it shows a T shape above the signal bars, then changes back to the H after a few seconds

Only using data/internet with 'H' or 'H+', not 3G

Something strange I've noticed with my Galaxy S II is that data / internet will only work if the 'H' (for HSDPA) is in the status bar, but not with '3G' there...the green arrow will appear next to the 3G when I try to connect to something but it will just time out unless it happens to switch to 'H'.
Anyone know why this would be? Is only the HSDPA network working with my phone, but regular 3G won't?
It is possible that the 3G cells in your area are fully loaded with users.

i didn't read it well
Same problem here, on 3.
Wondered if it was the phone or the network! If it's a problem with the phone it'll be fixable/covered by warranty though, right?
Same here, it sits on 3g then i try to load a page etc and it goes to h like it carnt use 3g , im on t mobile and they have full coverage where i am

I found an older thread that says it's a feature, keeping the phone in 3G mode to save battery until you do something that requires data which switches it over to H. I've kept a closer eye on my phone and that does seem to be what it's doing, usually taking a second or two to switch over each time I use data.
However, there have still been some times where it stays on 3G and is unable to load data.
Yeah i think your right and also it does not change sometimes and kinda hangs, be nice for it to switch over to H abit faster without battery drain.

I have the same issue with my phone to on t-mobile, not working on 3g then working on H.
It is a right pain to be honest.
No way of stopping this battery save? I would rather use more battery.
It's the network. I have no explanation but only Edge and HSDPA work whether on Samsung or Nokia.
Just tested, this does not occur for me, at least right here, right now. Comfortably loading pages on Google with just 3G signal (T-Mobile UK).
It's faster when I stand on my bed upstairs for HSDPA but 3G does work. Stock firmware from T-Mob, no modifications.

Hey mate,
I have the galaxy s i9000, with optus here in sydney. same problem, only switches to "H" when i make some sort of data request (load a page, open an app that uses internet), it takes a couple of seconds to switch from 3G to H. Sometimes, it keeps flicking back and forth between 3G and H like its having problems connecting to H
I complained to optus, they reckon i'm lying. Go figure.

Sorry.. just to add on, i've tried about 13 different modems on my i9000 and it happens with all of them.
The only fix I've come by? dial *#301279# and disable HSDPA altogether thats the only way my phone will actually load any data on 3G
I have the same thing, but as i understand H and H+ are the highest form of 3G, not a different thing. So I am wondering what mode we are in when 3G appears. UMTS?
Its all very annoying to be honest.
None of my other phones have this problem as they always stay on HSPDA
Same problem here to the extent that pages fail to load on 3g and come up with the error then when I refresh the page once its on H it loads straight away.
Actually this problem is making my phone more or less not usable.
I use the slingplayer alot, keeps skipping on the Galaxy S II as it seems to keep switching between H and 3G.
Put the sim card into my ZTE Blade (Orange San Francisco) and streams constantly with no problem with signal staying on H.
With all the threads relating to 3g and connectivity issues..we can deduce that SGS2's modem really sucks big time..and still no firmware update to correct this even though large number of people is facing some sort of problem with mobile internet which is a main function on todays smartphone.

Anyone know who to e-mail with examples at Samsung?
I guess they won't fix a problem if they don't realise there is one.
Some people will prefer longer battery when its on 3G then H, others will want the constant H.
I got mine a week after it released. The first two updates mine did the same thing, but instead of timing out, it would drop all signal and display the circle. After a reboot signal would come back. From KE7, it has not done it again.

same problem, mode switches around when using data, 3 australia

Fix/Workaround for mobile data connectivity problems (3G/H/H+ dropping connection)

I've been following the mobile data connectivity issue that some users are experiencing (where data connection drops randomly, apparently coinciding with a lot of switching between 3G/H/H+).
Initially, people suggested disabling 'fast dormancy' using *#*#9900#*#*, however, this did not work for many, including myself.
In this post http://forum.xda-developers.com/showpost.php?p=15250511&postcount=6, there appears to be a solution, albeit a workaround.
I have started this thread, as there are so many separate threads about this issue, and only the Telstra Australia thread had this answer (as far as I've read). I have copied the post (a repost from whirlpool) by dusty_nz below. Basically, the problem is serious, the guys from Samsung have insisted this will be fixed in KE9, but there is a workaround in the mean time (disabling H+ and H, or just disabling H+ using *#301279#). This may seem drastic to speed freaks, but 3G connection alone should still give you 1.5 Mb up/down if you can put up with that. This has worked for me, no more data stalling, no more server errors etc. etc. I hope H/H+ will be fixed in future firmware.
Here is the post:

****************** FIXED ******************
After contacting Samsung for an insane period of time (ended up on an international call to England i think... or now that i think about it could have just been some English guy in Aus lol) I have got an official explanation and confirmation that this issue is being looked into for KE8 (but it appears that KE8 has been launched in India already so it might be KE9).
*disclaimer*
I am no expert on mobile technology this in-depth however the (probably very) dumbed down version the Samsung guy told me was this;
*end disclaimer*
The problem stems from the fact that this phone has 3 forms of data connection, 3G, HSDPA, and HSPA+.
3G is what we have all had since 3/Telstra launch 10 years ago.
HSDPA is the 7.2mbps connections that we got after that.
HSPA+ is the full fledged 42mbps Next G stuff that only Telstra has.
The problem is, when you are just using the phone as "a phone" it idles on a 3G connection to save battery and when you initiate a data connection it flicks on to the higher connection protocols for better speed.
What is supposed to happen when you initiate the data connection is the phone checks for H+ connection, then for H and then finally 3G. For some reason if you arent with Telstra or are in an area without HSPA+ the phone gets hung up for too long attempting to initiate the H+ connection and refuses to drop back to H!
Also, even if it does give up on H+ it then has an issue with falling back to 3G. Resulting in the problem that if it cant get H+ or the tower is too flooded for a H connection you get absolutely nothing until you restart the data mode within the phone, renegotiates with the tower and BAM, you are back in business.
So... there are 5 fixes;
1. Wait for KE9 (or what ever firmware fixes the modem timings etc)
2. Get a Telstra sim and never leave an area that has H+
3. Turn off/on data mode whenever it happens
to which i told him they were stupid answers and completely unacceptable, but then he came out with this complete gem!
4. using service code *#301279# you can turn off HSPA+ completely forcing it to start the data connections on HSDPA
5. using *#301279# again you can just turn off HSPA+ and HSDPA meaning it instantly starts downloading the data on 3G without delay
Now yes, i thought... great... ive bought this $779 phone that has all the latest and greatest technology and I cant even use it! But, I did some testing!
First of all my normal sim is Vodafone so turning off HSPA+ is an obvious one for me, im never going to get it so why bother. So now that the phone only attempts to get a connection with HSDPA the need to turn off and on data connection was getting more and more rare but still having the problem (i have a feeling that is due to congestion?). So i bumped it down to 3G only and it works perfectly 100% of the time!
The point of these faster connection protocols is speed so i did testing.
Vodafone sim, 4 bars of signal in the middle of a shopping centre.
HPSA+ turned on = 4mbps down, 1mbps up
HSDPA turned on = 4mbps down, 1mbps up
3G only = 3.5mbps down, 1mbps up
did this over and over and over again and to be perfectly honest, im willing to lose 500kbps to make sure that data always works and if you are just doing general web browsing the time it takes to initiate the HSDPA connection wastes more time than the slightly slower speeds with 3G does.
Now obviously this only works fine in my situation, if you are with Telstra and going from HSPA+ down to 3G means going from 20mbps to 3... i would be pissed. But for the rest of the country you are talking about a loss of less than 1mbps so in real world situations with just small amounts of burst data its fine
TLDR; Try and go online and the 3G up arrow lights up but never actually downloads anything
Dial: *#301279# – Change HSPA revision – Release 5 HSPDA only
test, if still a problem
Dial: *#301279# – Change HSPA revision – Release R99 HSPA off
Your welcome, Peace out!

this works! thanks!

Just tried this and I got 1800kbps on 3g!!
Hmm, i played around with those codes. If i choose to drop H+ and H, stays on 3G, but speed is crappy for me. So i want to drop only H+, but when i do that phone stays only on 3G too, not attempting to connect to H. Am i doing something wrong ?

*#301279#
Option [1] Release R99(HSPA OFF) - This should turn H+ and H off
Option [2] Release 5(HSDPA ONLY) - This should turn just H+ off (what you want)
Option [3] Release 6(HSDPA/HSUPA) - This should turn H+ and H on
To test this, you might want to make sure you are in an area that can pick up 3G, H and H+.
One week on since I selected Option [1] and I have not had any data stalling issues, before I was having data dropping every few minutes whilst browsing.
I tried Option [2] and still had the stalling issue.
Good luck.

I hardly ever get H+, which is why i want to turn it off, thing is if i choose option 2, i only get 3G, while with option 3 i get 3G and H (probably H+ too if i were in the right place). Option 1 works fine, doesn't seem to stall, but 3G speed is crap in my network, that's why i wanted option 2.
Tried all three settings and I am getting about the same speeds with all three settings, 3600-4200 down and 1550-1620 up. So will try setting 1 to see if my connection carries on dropping out.
Thanks
Wat is the code for miui
Sent from my GT-I9100 using XDA Premium App
I actually tried this before on a few different radios and it didn't really work. The real problem I have is when I get in an elevator for a minute and get out shortly. It's not long enough in the elevator for the phone to say "No Signal" but it's still long enough for the data connection to hang and never bother hooking back up when I get off the elevator.
I'll try again though... will report back.
same here .... i tried the three options but problem persist
I have tried the codes above, including disabling dormancy but my internet still will not connect to the internet. Please help.
I'm with Optus (TPG) and I never really see H. It's either 3G, or H+.
I tried disabling H+ (option 2), and like the other guy now I only see 3G.
My Speedtest with only 3G was:
Down - 228.2kB/s
With H+ enabled (option 3), my Speedtest was:
Down - 482kB/s (but it's been as high as 1103.9kB/s in previous tests.
For now I'll just keep it as it is and put up with the occasional freezes. Hopefully it's fixed soon in a firmware release.
i cant seem to get the codes working.. after i dial *#301279# nothing happens, no menu nothing. tried on my wife's galaxy s 2 same thing.. is there an app to disable HSDPA?
\\Issue solved
Is this issue mainly due to the carrier?
I did not have this problem b4. Now I found that my phone might suffer from this.
Tried to disable the H+ or H & H+ at the same time, it seems the issue is still there.
I am on Vodafone Australia network. And I just raised this similar topic on Whirlpool, if you guys would like to discuss this network problem on an OZ forum, plz refer to the below

For me it's still the same, coming from KF2 to KG2. Will try KG3.
Any one with new modem firmware that 100% fixed the 3G drop/stuck connection(only see upload sign lit) bug? I am running KG1 modem(stock rom no root) and still experiencing this issue on ATT in Bloomington, Indiana USA.
I also realized S2 uses Infineon modem chip which is the same supplier for the iPhone3G that had the 3G slow down, drop call issue..
Could this issue be the chip at the end?? Why would Samsung taking forever to fix this critical flaw on I9100??
I'm on 3 UK. Had the cutout on KG1 and KG2. But it's definitely gone away in KG3.
I'm on Airtel India on KG3 and I still have the data stalling issue.
Seems to me like this issue surfaces more when I'm at home on wifi and then step out to data.
Trying out these service codes now to see if it helps to turn off high speed data.
It would make sense for Samsung to include these settings in the rom itself even for those without issues but want to save battery.

T-mobile 3g/H+ switch delay/lag

I have a lag that takes 3~5 seconds for data to connect.
I am using PTEL, which rides on T-Mobile network.
The symptom is that, when I am Tmobile 3G/HSPA and trying to connect to internet from cold, I have to wait 3~5 seconds.
When the phone is idle, the icon stays "H". When I am trying to pull data, it takes a moment to change to "H+" and starts to pull data.
For example, when I open an article, I have to wait 3 seconds to connect to H+.
After finish reading it and try to load another article, I have to wait again to connect to H+.
My friend has Verizon LTE and when I use her phone, I am amazed how quickly I can browse through just like when I am on my computer with strong WIFI.
This is annoying and makes the battery drain.
On wifi, Nexus 4 can idle for hours and only lose 1% per hour.
But when it is on 3g, even when it is idling, it loses 10% per hour.
I think this 3g/HSPA lag causes the phone to be awake longer then needed to sync data.
I notice this because, sometimes the phone hangs forever waiting for data pull.
In that case I had to exit out of an app and go to chrome and try to access any website.
That helps other apps connecting to internet.
It seems that when I search about this connection lag, most of them have T-mobile.
I am wondering if anyone had similar issue and found a solution for this?
Is this also happening for folks who have Tmo LTE?
By the way, I am using Nexus5Experience rom and have left network configuration default.
I have apn that PTEL recommends which is "wholesale".
I tried "fast.t-mobile.com" and "epc.tmobile.com" and both have worst result than "wholesale" apn.
Thanks,
