Okay so i've got an aria rooted and flashed with the Liberated 2.2 rom. I've been using it for the past 3 months and I've noticed that I will go from full service while a phone call is comming in and complete signal loss when I answer it. I have set the phone on a table and watched the network signal strength go from -113 dBm and 0asu to -81 dBm and 16asu and vise versa. I have also noticed that when I lose signal my "H" for the data goes with it and service comes back a few seconds later very strong but showing "G". From there it will go to "E" then back to "H".
Could anyone explain this or have a better reason as to why this is happening? Maybe its just based on the connection where I live but I've used the app Antennas and the tower is about 1/3 mile away.
Any info or help would be awesome
Thanks
i'm not sure why this would happen outside of a poor bit of service where you're living.
i used the various roms for the aria and never had any sort of service loss issue.
as far as the icons switching around, e = edge network (2g), h = hspa (3g). when your phone drops its connection, it tries to reconnect as fast as possible, usually with edge, then after its strong it looks for the 3g connection.
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.

nvm
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.
AT&T in the U.S.
same problem, mode switches around when using data, 3 australia
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

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.

Please help:
I'm on CM9 19 6 nightly. Using Semaphore kernel without any modifications to the scripts.
The problem: My signal keeps on going out at regular intervals.
I've used XXJVU, DDJV5, XXJVT, KF1(Nexus modem for ICS) and various more. I stay on the modems for a week and then change to another one. The latest one is DDJV5 which I have been using since the past 2 weeks.
Tried all of the modems I could lay my hands on. Nothing works.
But the moment I come to work, the signal keeps fluctuating over the day. Sometimes it would be out for 10-15 minutes. When it's back, it would get back to giving -65 .. -71 dBm. It would stay like that for a few minutes and then it would be gone again for another 10-15 minutes or so.
It has turned into an OCD where I keep checking my signal.
This does not happen when I'm back home and then I'm back to getting good signal.
Yes, this looks to you like a locational issue. I thought so too. BUT, how did I get so good signal till a week back at work?
Question: What could have made this mess to my signal reception? How can I solve this?
No, all my syncs are OFF. I keep my 3G turned off and only use it once an hour or so for a few minutes. I don't use any signal consuming apps.
Also, sometimes the 3G would work even without the signal.
Another thing, sometimes there's a (x) sign at the signal bar thing and sometimes there is no (x) without bars.
As a cure for the OCD, I've taken an off from work today just to get some rest from checking my signal every now and then. And maybe find a solution.
I'm on Vodafone India.
Indians, I am on Vodafone India in Pune, Hinjewadi Information Technology park. Maybe Pune guys can help me out too?
maybe the phone changes the network mode.. 2g 3g or i dont know , try to put in in 2g only mode , or gsm only mode.
When the signal bar shows with a "x" it means the network is not available...go to settings and change the Network mode to "GSM Only". It will solve the fluctuating issue but network speed will be limited to 2G only.

Is going to 2G mode my ONLY option?
How can I fix this and get back to using 3G?
Update:
Changing to 2G mode fixed the problem. BUT...
I have a few questions now:
I want to use 3G but at the same time I don't want the signal to fluctuate between 2G and 3G—want to get constant 3G connectivity without signal fluctuations. Is there any way I can fix that?
I remember reading somewhere that going to recovery and changing permission helps this.
Anyone knows how to change the permissions so the signal fluctuations stop?
I have done a lot of reading on XDA but I haven't noticed an issue like this.
CM9 guys, anything please...

I have the same issue mate...using 2G is the only option to get signal without any problem.
The problem doesnot lies on your phone but the problem is with the operator. The area where you live hardly 3G signal reaches there (same problem with me).
You got two options to fix this issue:
1. Change your Network Operator
Or
2. Settle to another location where 3G signal is fully available
Sent from my GT-i9100 equipped with Grenade Launcher and Remote Explosives
Both the options look impossible for me at the moment.
I will start living with the hope that the operator brings us some decent 3G signal here.
Thanks a lot anyways. It was helpful. Hope others facing the issue can learn from this thread. :good:

Complain to your provider, very loud!
:gooditto the same problem occured to me on Vodafone (Chennai) tried all modems listed above nothing worked ...Used to lose signals all the time with 2g data on especially at my workplace intermittently for 3-4 months ever since I upgraded to ICS..Sometimes used to lose signal even if data was off..multiple reboots/restarts gave no solution ..issue persisted across all the 15+ roms i might have flashed over the past 6 months..
Finally fed up I ported the number to AIrtel..everything works like a charm on JV9 I must say now..can vouch it's a network issue at the location
I am getting constant 5 bars on the 2G network. 3G gives me 2 bars at max.
Asked Vodafone about the future of 3G in my location and they said "We are spreading, sir. We will keep you informed".
I've had this problem too when the phone was constantly switching between 2G and 3G/3.5G. Try adding "Toggle 2G/3G" to notification drawer, set the "Network modes" for it to 2G/3G Only or 2G/3G Only/3G+2G. Switching between modes can take 10-20 seconds, but you should be able to test if you can get good enough 3G only connectivity (in case it is just a network switching problem like for me).
If you want 3G only, Dial *#*#4636#*#* - Phone information - WCDMA only.
this phone has started playing up, 4G wont connect at all and 3G is constantly changing between H and H+. Phone calls dropping and battery draining fast.
Have tried factory reset
flashing older Samsung firmware
Nothing is making a difference. Tried my SIM in another phone and it instantly connects to 4g.
This only started about two weeks ago.
Any one else have this issue? i'm in the uk on the 3 network.
UPDATE: it appears the 4G radio is faulty - setting it to 3g only solves the issues.
UPDATE : I'm so gutted that this phone 4g/3G is ****. Love the phone but loads of people and reviews suggesting 4g/3G issues with this phone and high number of call drops. I did a test today, I put my sim in an iPhone 6 and instantly connected to 4g and speed test was through the roof peaking at 38mb. Put the sim back into the s6 edge plus and only connects to 3G. But unable to browse the Internet. This confirms my fears that the 4g chipset/antenna are ****. In this phone. Which is a real shame as the phone is my favorite ever. Going to get an iPhone now. Connectivity is the most important thing and I can't be dealing with this crap from such an expensive phone. Shame on you Samsung.

I have the exact trouble as yours whichs about constantly changing between the H and H+. (4G is not matter, its new around here). When it turns on H, doesnt connect any site and application which need data connection. But H+ is doing normal. I bought an unlimited data package is provided for up limit 7.2Mbps. Dug something and saw that HSDPA(H) technology's up limit is 7.2 for our carrier. Then bought limited turbo data package(shows as up limit 43Mbps) but still changing H and H+ Thats not such for current device. It was in such an annoying situation since H+ available to connect. Tried to force use H+ but no luck. Sorry for long article and bad grammar. Just saying. Thanks.

Been doing a lot of research and it appears to me that this phone is crap at holding 4g/3G signals. I think this is a hardware/design fault. Most people won't release this until they test this on an iPhone in the same location and see the huge difference. Can't believe Samsung would release a huge pile of crap.
