Hi
Does anyone know how to fix this issue? I am in a good area for signal and with previous phones am consistently on H. With my S2 it frequently switches between 3G and H even if it stays in the same spot. It will do it every few minutes.
This is causing havok when I try and tether and my Transformer and laptop keep getting signal interruptions.
Does anyone have a fix? I have Fast Dormancy disabled and I'm aware there may be some other engineer menus that have signal settings in that might work?
Thanks
Paul

Interesting.. And I thought it was just my network vodafone
Mine also switches between G/H/H+ all within 5 secs... yeah 5 seconds and it is kinda annoying.
Are you on GIFFGAFF as stated on you profile? or other network? cause I thought if might have do to something with vodafone..
Otherwise may be its something to do with the hardware settings, I too would like to know the answer
I've kept mine to use WCMA all the times...

Yes, I'm on giffgaff.
Glad its not just me. Maybe the antenna is a little too sensitive.
Anyone know the secret code to get to the GSM/UTMS bits?

This thread has lots of codes, if any help i have no clue which might help us
OK. Found the 2263 code but that seems to want to enable/disable actual bands.
Am I looking into it too hard!?

Now, for me wouldn't 3G and H/H+ both be considered as WCDMA under Mobile Network Settings? G and E would be GSM right?
If that is the case, staying on WCDMA wouldn't fix the problem.

Your phone shouldn't lock onto a H/H+ signal unless it has started to download data. That's how the protocol works.
If your phone is sitting idle it should be on 3G.
You should only get H/H+ when your phone is actively downloading.

OK. So how can I stop it flicking between the H and 3G. For instance when I am trying to stream it will get interrupted, or if I'm wirelessly tethered?

i'm from tunisia and have the same pronlem here.
Please developers help us to get rid of this 3g/h issue.
Guys,
I got the same problem here i n Brazil using a VIVO carrier.
I set in CONFIG -> WIRELESS AND NETWORK -> MOBILE NETWORKS -> NETWORK MODE -> WCDMA ONLY
I don`t know why it worked but now its working fine.
Could you test?

No problems to report in Amsterdam.
I'm biking through the whole city to get to work, no disconnects using TuneIn or Google Music. Provider is Vodafone, HSDPA+ all along the way.
Its Android issue
Think when iPhone, Windows phones have not had this issue, wat else other than Android. I have tried 3 different handsets. 3 different network - 3, O2 and Vodaphone. All has same problem. Android is the only thing common. I have been scouring the internet and posted everwhere possible since Dec 2010 from when I became Android user. There is no solution. Everone seems busy making their own Android versions and apps. Result there is no basic data and voice stability on Android. Have been relying on my decade old treo to receive n make important calls. Wonder where this is going. My heart n soul seems to sway to the iPhone lately. Atleast wat they give works well.
Its Android issue
BTW those config settings are useless too. I have even used the code to get into hidden menu and change config but no use. It's the same issue. From H to 3g and from G to E I gsm.
Sorry for the question, but whats the problem with switching? I have the same thing but is not a problem for me.

Nobody should get worried about that switching, THIS IS NORMAL!
H/H+ is an high speed 3G protocol.
Basically:
1. 3G means DL 384 Kbps tops. The modem is under 3G signal most of the time. Whenever something on your phone starts checking/d-loading it communicates at THE BEGINNING under 3G protocol. Also, long ping time> 210 ms.
2. HSDPA max 14 Mbps/HSDPA+ can go as high as 42 Mbps ( topped only by cell tower). If there's need for large packet data or shorter ping time, IT AUTOMATICALLY SWITCHES TO H/H+(IF AVAIL). Hsdpa consumes more power and it's a communication protocol. When connected under H/H+ error correction bits are transmitted along data stream. It's like switching your home wifi on b/g/n. ...or like the automatic gearbox going to overdrive.
If you see a lot of this switching it means there's a lot of downloading/uploading going on.
I have it switching too between 3g and h on o2 and its making the internet so unstable you cannot do anything at all. This is certain not normal as the switch happens every second and continues to do so until phone is off
Mine is also switching to 3G once connection is idle for about 3 seconds. So far no problem and it uses less power than my SGS1 for browsing since my SGS1 doesn't switch to 3G when idle.
Mine is no problem between this signal switching, check your area or check your country maybe too much communication devices there so that's why it is distorted. Just use the common carrier with plenty of cell sites for a good signal of your phone.
What do i need to dial to fix it to 3g only from 2g?
As the title says, periodically wifi connections will cause my note to loose connection to the network. I will get the "no signal" crossed circle where the cell signal strength bar would be located....after that happens i have to restart my phone to reestablish the network connection. Wifi is not affected. No amount of toggling radio switches or going into airplane will affect the network loss...only a restart.
I am on the stock att Rom at the moment.
Anyone else experience this?

Every time I've encountered quirks with WiFi and cell signal on my android phones airplane mode for 15 seconds or so has fixed it. Odd.
Hopefully someone else chimes in for you. Bump.

could be a placebo, but i have noticed it seems to work as well.
Same here, but I do airplane mode on / off quick fast no wait.

Anybody have a fix for this issue?
Seems everyday, I will have to turn on airplane mode to jump start my mobile network. I'll see a signal (3-4 bars) and 4G/4G LTE...expect the signal bars will be gray. I always have to activate airplane mode and then turn it off, to reconnect to the mobile network.
I've reflashed my custom GB ROM (Flapp's) and no luck. I still end up having to do this at least once a day. I don't know....
RIL / Modem conflict perhaps?
Since getting my replacement EVO LTE, I have been having weird WiFi problems. I can connect to 5GHz WiFi networks without any problems, and the phone shows great signal strength. However, when connected via WiFi, most programs (Chrome, Play Store, etc.) can't access the internet. The weird thing is that the Speedtest.net has no problems running when I'm connected to a 5GHz network, and I get speeds around 15Mbps. The internet works perfectly when I'm connected to the exact same router at 2.4GHz, and my laptop has no problems on my 5GHz network.
Anyone else encountered this? The fact that Speedtest.net works makes me think it's not a hardware issue, but my old EVO LTE didn't do this.
Sorry to hear. Honestly I didn't know we had 5 ghz wifi. Thanks for the info.

I have a dual-band router and my 5Ghz band connects and transfers data at 60Mbps.
What ROM are you running? What kernel?
Connect to your 5Ghz band and wait about a minute. Then in the WiFi settings, tap on your network name and what is the speed it is connected at?

Ive read many people complaining about LTE, but does anyone else have issues connecting to 3g? Almost always when I leave WiFi range my phone wont connect to 3g unless I restart entire phone.
Sometimes Ill pull out my phone at random places to use google search or something and Ill have full bars but no internet connection (Yes my mobile network is set to on).
This problem happens next to my girlfriends galaxy which works just fine.
Its driving me nuts!
Happens to me alllll the time. I have to turn off wifi to get my phone to connect to the mobile network. Otherwise I'll be 30 miles from home and still "Connected to Wifi"
I thought HTC fixed the Wi-Fi connectivity issue in the latest ota, or was that just the one x

Originally i had that issue on my EVO LTE. but after the updates its been fixed.
Ironically my GS3 started to not want to connect to 3G after it was in an LTE area..
So i have been using my ole reliable EVO LTE..
At the moment although I'm not on a 4g plan I currently get amazing speeds on dc-hsdpa and this is displayed as "dc" next to my signal bars, however everytime it drops to "h" (assuming hspa or hsupa) my connection fails instantly and I can't load a single page till it goes back to dc-hsdpa. It only seems to happen in the area I live in really but it really is causing problems for streaming and Web browsing. It switches between the 2 bands constantly and very occasionally will pick up h+ but I can't understand while on h it doesn't seem to connect to anything? Sometimes it's so bad that I have to switch data connection off/on again! Any ideas? So frustrating!
