Yes, but fast dormancy isn't working for me. My phone is constantly on H and never switches to 3G. Do you see your phone switch from H to 3G when idling?
I just got my N4 and I definitely notice fast switching from H+ to 3G. It does seem to be when idling.

Looks like it's working with only some carriers. I checked with 2 carriers in my country and it does not switch on any of those. My old S2 used to switch, so it's some setting in N4 itself and nothing to do with the carriers.
Just add ro.ril.fast.dormancy.rule=0 to your build.prop

Are you sure about that. AFAIK, ril properties differ between manufacturers so property from one manufacturer might or might not work on another.
My phone is always on H and never idles on 3G so I tried to enable fast dormancy by setting ro.ril.fast.dormancy.rule=1 and nothing changed.
On T-Mobile, my N4 will idle on HSPA-10, but will jump to HSPA-15 when I transfer data. In both cases, it will only shows "H" in the status bar.
HSPA-10 is 3G (7.2), while HSPA-15 is 4G (HSPA+).
up!

that's what its supposed to do, hspa+ only when data is moving.

Hey guys, I have extreme data transfer issues. After lots of searching, Fast Dormancy seems to be the most likely cause for this. Switching from hspa to hspap goes extremely quickly when I request data (web page, music, etc.).
However, no data is transferred for around 30 secs to 1 minute after a switch to hspap.
I've tried disabling hspap in the build.prop, this caused an unrecoverable bootloop on multiple firmwares (including stock).
Wherever hspap is available, I basically have no data connection.
I'm not the only one with the issue, multiple people on German android forums seem to experience this with the Nexus 4.
So is there a definitive way to disable FD?

Ok, first off my Vibrant has flat out awful reception.. fluctuates randomly between 4 bars and 0 bars on 3g and sometimes cant get more than 1 bar 3g in the middle of an HSPA+ city(Memphis). Its not a bar display problem, sometimes my speedtest shows download speeds as low as 150kbps. If that wasnt bad enough it takes forever to switch between 3g and edge, by forever I mean sometimes a full 60 seconds+ and if Im running a data using program (Pandora for instance) it sometimes refuses to switch at all... Is this a known issue or is it just my phone?? I know my G1 did not have these issues.
Try doing a master reset on your device.
If the master reset dosen't work, you might reflash the full stock rom from the android dev section. There's alot of people that have been reporting substantial increases in their reception and connection speeds.
And if you think it takes a long time to switch b/t 3g and edge, you ought to try owning an evo for a month. It takes FOREVA to switch the 4g radio on and off, at least 3 min for me, takes about that long to turn it on after a reset too.
Just because you're in a HSPA+ city doesn't mean you're on the HSPA+ network.
If you're having problems with it aquiring the 3G network try a new sim.
The G1 has mediocre reception but it is aided by the fact that the antenna is at the top and not the bottom like all other phones.
Bump,
I am actually having this problem too, I have tried a factory reset, I also tried reflashing the T-Mobile stock fimware, but it has not helped. I have good 3g and edge reception where I live.
Oh yeah, I am using ATT on the vibrant.
When this happens (ie. not switching between network or slow switch time), you can trigger airplane mode and then undo it and the phone will pick up the right network or switch network faster. For example, if use 2g network is checked, it will enter Edge, etc.
I see exactly what you guys are talking about, locking it on 3G will fix this right up. I was driving down the freeway and I KNOW I was passing 3G towers, but the Vibrant stayed on EDGE for way too long. I locked it on 3G and I never lost the signal and it was 4 bars for nearly all of the trip so I know 3G was there, it just wasn't switching back fast enough.
Looking under the Samsung debug mode, the Vibrant will hold onto 3G until -115 Recieve power, which is basically -115dBm under the Android network menu. Of course over -101 RSCP, it will show 0 bars so it's hard to know when reception is acutally really bad.
It should show -0 bars at -113dBm, 1 bar until -101dBm, 2 bars until -89dBm, 3 bars until -79dBm, and 4 bars until -51dBm.
just disable the extra frequencies from service menu and it will be super quick.
I'll try that, at any rate it should be remedied by Samsung.

I'm pretty sure hes talking about only having it on 1900/1700 (combi bands)

Does it matter if you flash from nandroid backup or oden?

That's an unintuitive user interface. sheesh.
Looking at Wikipedia, it looks like TMO uses 1700/2100 WCDMA and 850/1900 GSM (2G/EDGE). There's also a WCDMA 1900, but according to what I'm reading, TMO doesn't use WCDMA signaling on 1900, just GSM/EDGE.
To try it, go to the service menu using the steps for 3G locking and select 1700 only instead of WCDMA ALL. Then go back using menu/back (not the back button) twice and go to Combi Bands and select WCDMA 2100. That should enable just 1700/2100 WCDMA 3G service. Turning on PCS 1900 does seem to get me an EDGE connection. Enabling GSM 850 ONLY gives me emergency calls only, so it might be worth keeping on for 911 calls. 850 goes further so it might have service when the others don't.
I don't get 3G service in my basement, for example, so I would like to keep EDGE enabled. Hopefully enabling just the bands that I would use will help keep the search times down.

To really get a full re-flash, you need Odin right now. It should be possible to do it without Odin now, but I don't know if anyone has put together a stock ROM that way yet.
I didn't see any difference in speed/stability with the stock Odin flash, but others might have. It seems to depend on the network more than the local stuff.
Band IV 1700 includes 2100Mhz so you don't have to enable it. From what I can tell, no.. combi-bands doesn't do much for the slow 3G requisition. I'm just going to lock it on 3G when I'm not at home.

This didn't work for me. I would do this, and it would only work changing from 3G to EDGE. But, from when I would put it on use 3g, it would first change from airplane mode to EDGE, then take around 1 min to change to 3G.

How do I disable the frequencies? I can only seem to enable them.
When browsing or tethering, unless the connection switches to H it is basically useless - won't even load google.com. I am aware of the speed differences between 3g and HSPA but is this normal?
I'm running CM7 nightly.

Yes.
It's not useless, it's just slow - and having HSPA, your basis for comparison is subjective and flawed. Measurement with SpeedTest would tell you the exact differences in numbers - but in user experience, the difference seems way more than the numbers show.
Moreover, when your phone attempts to connect, if the mobile network stays on 3G - it can mean that it has no reliable connection.
for me 3G=HSPA
it says 3G until im pulling data and then it switches to HSPA, ive never pulled data while on 3G

3G is UMTS. HSPA is like 3.5G. They didn't call it 4G because it was more of an additional way to provide a slightly better 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.

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
So i finally got my nexus 4 and I'm on T-Mobile network and noticed that at work i notice my signal is constantly switching from H (HSDPA+) and E (edge). It's kind of annoying since edge data is very slow. Is this a common issue with the n4? When i get H signal, i have two bars so i don't think it is being boarder line signal. Please let me know, really hope i don't have to return this sweet phone!!!!
Are there any updated radios yet that i can try? I know with Vzw galaxy nexus radios helped a lot with 1x/3g/4g switching.

Any info on this? I know what the symbols stand for, however why can't this hold a strong HSPA signal for more than a minute without switching to edge even if the signal is 2 bar? Doesn't seem right
check your APN's

It happens to me as well but its not just my nexus 4. It happens to my iPhone and my brothers HTC one v. Its just that we have decent to bad signal at home. Signal gets spotty sometimes.
So if you're at home just use WiFi and leave data off.

Thanks for the reply, any info how how to change the apns and what the best ones would be? I have been reading many people say their n4 idles with 3g and then ramps up to hspa when it calls for data usage. Mine doesn't act like this and just randomly drops to edge
Mine stays on 3g and only switches to H+ when I use data (custom rom icons). I think its normal
There is an app that takes you into the menu where you can choose network types, this is what is used to turn on LTE. Go in and put it to WCDMA Only, that should make it stay only on H+ and not go to Edge.

If I try to go into the settings>Select Radio my com.android.phone FCs is there a way around that?
I am on stock 4.2.1
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.
