3G not working, but HSDPA is.

Hi All,
For 2 weeks or so now I've been having an issue with my Hero's internet connection. Didn't notice specifically when it started as it only affects the 3G connection and I mostly get HSDPA in my area. I use WiFi at home anyway.
When the notification bar shows 3G, the upstream arrow flashes periodically but there is no traffic downstream. Market downloads fail, anything which requires an internet connection will timeout.
However as soon as it switches up to H connection, it starts downloading immediately. If I switch to 2G only GPRS and EDGE connections work fine too.
Around the time the issue started I was trying a few different 2.1 roms for the first time. Have flashed several different roms since and have the same issue. Currently using VillainRom5.5. I was already using Radio 63.18.55.06JU_6.35.09.26 but have reflashed this too. Have flashed the stock Orange RUU, RUU_Herrange_UK_2.73.61.5_release_signed_NoDriv er.exe, but the issue remains.
Didn't have a problem, especially at home, before trying the 2.1 roms. I have good signal regardless which connection I have, currently 3 bars.
Thought it might just be an issue around my house but have tested all over and it's the same. Became an issue this week as I was visiting Somerset and in area's without HSDPA. Had to switch to 2G only in order to get internet connection.
Have searched here and other forums but cannot find anything specifically like this, any help greatly appreciated!
Cheers,

hello,
I had a lot of problems with connections (3G/HSDPA/2G) with loose of signal.
I tried a lot of ROMS to solve this problem. But It wasn't the right way...
In fact, My SIMcard was defective. I had to change it, and now all is OK.
I'm not sure that it will be the right issue for you, but perhaps It could be...

Cheers for your reply.
Have contacted Orange today, the customer services guy tried some stuff and asked me to test and call back. Hasn't helped so will call them back in a mo and report back.

Hi,
I am having a very similar issue and I am also on Orange. My issue started after around the time I flashed Villian 5.3 but I doubt this is the issue as I have flashed other ROMS since and have the problem. Have you also done the 2.1 battery stuff by *#*#4636#*#*? I did this around the same time the issue started and I thought it was because I had set it to GSM (auto) but I put it back to WCDMA but that made no difference.
My phone keeps showing 3G then swapping to HSDPA. This is both an my house and in the city. I always got H no matter where I was but now keeps swapping after a couple of mins or when I use internet. I've reflashed ROM, radios and tried a friends Orange SIM and I get the same.

I also have the exact same problem on the 3 network in the uk, definately not a sim problem as before I rooted and flashed it all worked perfectly. Hasnt been too much of an issue as most of my city has hspda coverage but if I go out of town its a pain.
Problem started as soon as I flashed a villain ROM and is present in all 2.1 ROMs I have tried although I have noticed that the legend ports seem more stable and connect a little better, so am currently running the villain 4 ROM. Updating the radio made no difference and I am starting to wonder if it is some thing to do with using a CDMA port?

Yeah I did try that stuff, I too have set it back to WCDMA Preferred. Now you mention it I guess my issue did start around this time too so its likely to be linked.

It does seem too coincidental that we have done the same things and are having the same issues on Orange. I'm going to wait to see if ROM from the official 2.1 build sorts it out and if not swap the phone out. I've had Villian and now BeHero + and still have the issue. I've flashed different Radio's as well and that has not fixed it.

Ive had this problem for well over a month now, way before the gsm auto trick came on the forums and I started using it, I dont think thats the cause, dont think its a radio issue either as had it on two diff radio versions.
My issue started as soon as I flashed a eris port which as far as I know is cdma based and isnt that a different kind of network than we use over here??
Any devs want to chip in here and help some noobs plz?

I've always had this issue with Orange as well, regardless of ROM, prior or after to flashing. I thought it was just the Orange network capacity as when I use the phone out of peak hours (2-7am) its fine.

I have the stock Hero with 1.5, no roots or custom os & it happens to me on Orange UK.
No idea why, but don't think its to do with custom roms!

Yaeh i have the exact same issue, tried many different roms, including official orange roms. This issue started before i started playing with customer roms.
Anyone have any suggestions?

Just adding to the list. Same issue for me, Orange UK - not specific to any ROM (Stock or Custom)

I'm going to join the party and say I have this problem too.
Although I didn't notice until I read this and checked, I just assumed Oranges 3G network was unstable in peak times

I too am on orange uk and tried this and experienced the same issue.
The solution is just reflash rom and radio (no wipe etc so data remains). That fixed it for me.
Also don't mess with *#*#...... settings

I'm still having this issue, maybe it is just the Orange network thats to blame? Seems to be to a number of us cropping up.
Gonna get back onto Customer Services this weekend, see what they say this time.

Same problem here. I'm on Orange UK too. Seems like an Orange network problem rather than a ROM problem

Saw this on my G2 Touch Hero on t-mobile when using villainrom 5.2. Not seen it recently and don't think its related to flashing 6.0.

Thought I'd update this.
Been living with the issue since posting, tried a few roms, all with the same issue.
Tried the latest radio, that didn't help.
Flashed EzHero rom few days ago and 3G has been working fine since! Don't know whats in this rom which might do that, it doesn't display the 'H' icon anymore which is the only visual difference. Might just be coincidence but either way glad its working consistently again.

I've had the same issue here on the other side of the pond in Canada on the Telus Hero. I think it has something to do with the phone trying to default to the fastest connection. I'm assuming the providers don't want us connected to the faster networks constantly, so they have a disconnect on idle response; which in turn is being counter-acted by our hero's need for speed. That is one theory, but I have to include that when I first got my TELUS Hero, before rooting and installing MaDaCo 1.5 I would have stable 3G connections. Any ROM installed following the root of my phone has caused this same dilemma.

This is a big issue on orange one which I have never got to the bottom of.
Now my phone seems to work 99% of the time but it always switches to H before downloading.
It might be something to do with Orange switching to new "next generation" towers. Apparently last time I phoned orange my phone was connected to two towers (only supposed to be one) so it was impossible to triangulate my exact position.
This might have something to do with it.

Possible fix for data stalling issues some of us are having.

Right, a little back story.
I brought my SGS2 at the start of May in the UK on O2 so I have an early model which came with the firmware before KE1. I rooted in the first week and was flashing Villainrom 1.0 before too long with no data problems.
I think it was around KE2 with Lite'ning rom that I first saw my phone constantly switching between H & 3G and stalling when receiving or sending data. This behaviour has continued through all the firmwares I've tried with many different modems. I moved onto to Cognition when it was v1.01 and have been using it all the way unto 1.2 with the KG3 modem. Again still with data connecting problems.
Things I have tried -
Turning off fast dormacy
Editing the build.prop http://forum.xda-developers.com/showthread.php?t=1097612&highlight=build.prop pages 1-5
Switching off HSDPA/HSUPA via the *#301279# command
Disabling juice defender
Switching to WCDMA only
Changing modems
Full hard reset and reflasing of roms
Even with the above on multiple roms and rom versions my data connection was unreliable at best and killing spree warranting at its worst.
Possible fix-
What i found lurking on XDA on a slow day at work was the command below
*#2263#
This allows you to select which bands your phone uses. I selected option 2 then tested the 4 available bands. They all resulted in a complete loss of reception except WCDMA 2100. this is probably network specific you'll need to try it yourselves.
The results and current settings
Now when I try to use my data connection the phone no longer switches between H & 3G. It will start on 3G then find H and stay there, I see a slight delay if its been in deep sleep or JD has cut the connect but this is normal for the phone to start on 3G to save power.
Fast dormacy - off
build.prop -stock/unedited (I found this worked for me for a while but since 2.3.4 it didnt seem to help)
HSDPA/HSUPA via the *#301279# command - both on
Juice defender - on
WCDMA only selected as when picking a band it doesn't seem to like having a GSM band selected as well (happy to be corrected on that)
Modem KG3 -
Rom cog 1.2 - I'm patiently waiting 1.4 based on KG6 to test my findings.
Conclusion-
Okay it could be that selecting a band does F'all and that I'm seeing better results for a completely different reason. I'm not a developer so my fixing skills amount to playing with stuff I don't fully understand and seeing how more or less broke I've made it.
After thought -
Ive seen on the sensation forum they have discussed the wrong IMEI code being the cause of poor data speeds so I may look into that next.
Please share your experiences and anything else you've tried.

That should be no connection as IMEI belongs to phone and handshakes with network first .
KG6 modem some report as better .
jje

I will have to give this a try and see how it works, thanks for the share.

I am in the same boat, it is VERY frustrating to say the least. A typical scenario for me is: reading a web page on my S2 for a good few minutes (3g has gone to sleep mode by the time I have finished reading), I click on a link, 3g flashes, H comes up and flashes once.....wait.....wait.......wait......10 seconds later it decides to initiate a connection and take me where I want to go! It does the same thing with the XDA app. I have been onto O2 about this a couple of weeks ago, all they did was give me the settings over the phone (which were the exact same ones I already had) and they also sent me a replacement sim card, suffice to say, there is no change. Now I am convinced its a network problem of some sort, I have a three sim card which I have been trying out and the above problems do not exist anymore when using three, I click a link after 3g has gone to sleep and it goes from 3g to H and initialises the data transfer in one smooth motion. It looks like I'll be getting my PAC code and moving to Three!

would be interested to hear if switching to the 2100 band helps at all seeing as your on O2 as well

Mine is O2 via Giffgaff and no problems at all .
Tested KG6 modem Wi|Fi only and it is a stronger signal .
jje

Yeah, forgot to mention that, I have just enabled it. I can't test at the moment though coz there is no 3G coverage where I am. The only problem with enabling it is you will not be able to connect to GPRS or Edge if you need to. But it is worth testing regardless.

Just been out and about and tried that setting, didn't make much difference unfortunately

Maybe it was a combination of tweaks on my end. What rom & modem are you using?

Villain 2.3 with KG3 modem. The problem has been the same whatever ROM I have used, I even flashed back to O2 stock a couple of weeks ago to see if it was a ROM problem, but that was the same. I can't remember what it was like when I first got the handset though, mine was the first batch as well.

The wife is on Giffgaff so I think I'll give that sim a try before I get my PAC off O2.

hi
i am just testing now this fix. i have an o2 phone and i did the same changes you did, disable fast dormancy, changed build.prop settings, will let you know after going a few times underground ;-)
gabrio

confirm, this is working, even when i go underground or when the signal goes away, it gets back to H/H+ and works, gabrio

Give it a little while, I think you'll be back saying it didn't work
Personally, I went ahead with my threat and moved over to 3uk, never looked back since with this problem, been perfect!

I've tried it all. Disabled fast dormancy, hspa, toyed with band selection, edited build.prop (btw, don't bother with it, the network settings you find on the web to type in don't work on the s2) you name it - but it would still cut out. Luckily, my phone is unlocked so I switched my provider and now it works like a charm with all the bells and whistles enabled. I can ride the tram all across warsaw and maybe have a handful of 2-3 second hiccups when I'm listening to online radio. Curiously enough, on my previous provider I've noted that there are some areas (like a busy mall - Arkadia) where it would not stall as well as a few other places, and most other areas that were notorious with data hanging. I'm convinced now that it is an issue on the telco side (*cough*Orange*cough*), and too bad because I was on a prepaid plan with them that for roughly $30 I had 7GB of transfer. I guess they figured they can promise the world on their trash network, because nobody would actually use it up. YMMV.

Had this issue with a UK GS2 purchased from Negri using it on AT&T.
Since upgrading to the latest UK firmware with 2.3.4 I have not had the issue going on about 2 weeks now!
Man was that issue annoying. Had to restart the phone sometimes to get data back.
Joe

Ok I did that too though how abt lag? Phone lags a bit opening large sms conversations and browsing home screens.. But peace. Yours too?

s4 data connection issue comes from my 9505...

Helo all..
I just brought that phone s4 9505 lte version for 1week ago. And at that time I did not find any issues on my phone. As u know I only checked using wifi and play games. It seems to work well everything. But today I am realized that something wrong in my galaxy s4 particularly when I use data network. The main problem is in the H symbol that always appear in the top of the screen with 2 sides arrow. When I do nothing with my phone or idle for a short while, the data connection suddenly stop working which means u can not browsing at all even making a call and texting. So the only way is to refresh the network or change the mode or restart your phone.
I dont know why it always happen in my phone many times. I have tried to refresh network and change the mode then give back to the wcdma mode. It occurs same issues again after a couple hours. But I did not notice where I use gsm mode.
About my signal is good. No drop signal at all. But I always encounter that problem. Maybe anyone who has the same issue .. plz inform then we can try searching out the solution. Thx

Addition information.. I buy this phone from singapore comes with official local warranty.
Actually. I have not tried to change another provider and I hope this cell is not fault factory.
I will try with different area and provider first then decide possibility

Are you on vodafone? There is quite some discussion going on in german forums where the lte - 3g change seems to be problematic when on vodafone network with the i9505. If so you might want to check forums like android-hilfe.de or so. Btw. Im in switzerland on provider swisscom and have the same problems. Data connections drops completely every few minutes. Very annoing.

Yes I notice in other sub thread there are quite a lots number signal problematic. Yet in my case is different from that case..
I just tested set into wcdma mode along night and until now it still work perfectly. This problem can not be predicted when it will occur. Sometimes I browse internet for 2 hours..afterwards my phone can not be used completely even testing and calling. I hope this is a provider caused.

[Q] i9505 stuck out of service

Hi,
I have a weird problem with my S4.
At work I have some areas with really bad coverage so sometimes the phone can stay for a few minutes (or even say 1h) out of service.
This is all normal. The coverage sucks, the building is weird, not problem here.
The problem is that when I go outside where the signal is normally full it does not register back to the network.
Even more it does not even go to "emergency only mode". On a few occasions I arrived back home (10Km + drive) until I realized people can't call me because the phone is out of service.
What is even weirder is the fact that on some occasions, even though the (no service) (/) sign is displayed mobile data works just fine.
My previous iPhone did something similar too - it took a while for it to recover signal after exiting the coverage black spots but never more than maximum 5 minutes.
To me it looks like a radio modem issue and maybe this is aggravated by the fact that my carrier uses the same 2100MHz frequency for both Data and Voice.
I would like to know if any of you have experience anything like this or if there is some app available that can monitor what's happening.

what network and firmware you on and wich s4 variant:thumbup:

It's Europe standard i9505.
Network is Digi.Mobil Romania - but I doubt it's relevant since it can't get even emergency only (other networks).

so... any idea?

Android needs to work on it's notification. No Service and the reception bars only gauge voice coverage. You can test this out by using Service Mode to do a PS Only (data) attach instead of the standard PS + CS (voice) attach. It'll say no service, but data will be fine.
Emergency only, is when there is coverage from other operators but not yours. No service, means your way off the grid.
I've noticed the issue you describe and it's only on some firmwares. Try a newer one and see if you still have the same issue. But you might notice a drop in your battery life because your phone will be scanning all the time. If you're happy with no coverage at work, best to just turn it off and then turn it on when your outside.
Best option is to tell your operator about the lack of coverage. There's someone in charge of stats who get's beaten every time you drop a call. You'll get extra attention if you've got other businesses around you, so let them know that too.

Thanks for the reply.
I am already on the latest firmware and I noticed the same behavior on the firmware before this one.
Unfortunately I can't try out other modem versions (from other FW packages) as that would void my warranty.

but...what about reboot phone? i know isnt funny but until u find a problem u can just reboot ur phone while u are going out from ur office...or just try to enable and disable airplane mode

Of course reboot works but I am looking for a solution, not a partial workaround.
The most annoying problem is that if I forget to reboot it when I leave work it will not recover network connectivity even if I am in areas with very good coverage, areas where you would expect your phone to work.
It looks like when it decides to give up it does not try again. It is very weird that it also drops the signal from other networks (the "emergency only") even if it's well in their coverage areas. I guess I will have to switch phones... Even if this issue was present for the iPhone too it never took more than a few minutes for it to recover on its own. And I'm not an apple fan

Just to do some brain ecercise...do u keep in power save when u are out of signal ? Its possible that disable check after few tries
Sent from my GT-I9505 using xda app-developers app

It's not in power save. I only use that function in case of battery emergency.

Same problem here
Hello, I have the EXACT same problem here. I am in Argentina.
Now, I've been in the USA for a few weeks, visiting, and while my phone was roaming, I didn't have a single problem with my phone.
Since I came back, 3 days ago, I haven't had any problems in Argentina, either.
Is it possible that something got activated when the phone was registered to another company? (it was AT&T i believe)
If that's the case... maybe you can try putting a sim card of another company and see if you still have the problem?
Please let me know if you still have the same problem or if you got it solved. I would love to know something more scientific about all this.
I don't know if this is relevant, but my compass is off by about 30 degrees. Maybe my phone is defective?
THANKS FOR ALL YOUR HELP YOU CAN GIVE ME WITH THIS

Hi I have similar issue,
My phone says its out of service or no signal or no network also I checked my sim card in other phone in the same place and it is fine. The i9505 model in ireland meteor provider was running ok until deicided to give a try to another network operator, when I changed the sim card it didnt only catch up the signal from new network provider but also it refuses to catch the old network provider. Funny thing is that I am receiving 3G but no signal bars and no service sign is beeing displayed. I am running latest official BTU (UK) firmware, the phone was never rooted, altough I had to remove the simlock and instal unbranded firmware. The phone worked fine with the newest updates for a month and now I am facing this trouble.
No factory resets nor installing same radio (couple of times) have helped. Also I used odin to instal same firmware (as it has locked bootloader) so I cannot revert back to other stock firmwares, but still no joy.
hope that someone faced the same problems and describe how to solve this issue. thanks

I9505 Signal problems

Hi
For a very long time I've been having signal problems, it just suddenly stops working and I have to reboot to get any signal back (airplane mode on and off doesnt work).
Its a GT-I9505
4.4.2
Goldeneye Rom
Greetings

which network? might be a local network issue?
I'm with 3, and although officially their website says that there's no planned maintenance in the area, i quite often drop signal when I'm at work recently, even though it's worked fine until now. I think a lot of people on various networks get the occasional network issue though. I think companies are constantly "upgrading" things, leading to network outages. I don't know why they don't just leave things alone. I used to have perfect signal on t-mobile when it was 3g, but as soon as they changed to ee and started to move to 4g, I got no signal, ever....that's why i switched to 3 in the first place, but now that they're "upgrading", same stuff again!

Its not the provider, know a lot of people on the same company and only me and my brother (same phone same firmware) are having this problems.
I read it coul be the 4.4.2 firmware, but dont know if only updating would fix it.

I had this problem on an earlier version of a cyanogenmod nightly. Most likely is your custom rom causing it. You said it yourself. Both you and your brother, same rom, same phone. Try a different rom or different version of the same rom.
