HSDPA icon stuck!

I turned on my Tilt this morning and where the 3G icon used to be it is now a H icon all the time even if I am not connected to the network or downloading data. I have tried disabling HSDPA and reenabling it, but that hasn't worked. Disabling and reenabling the icon itself also doesn't get rid of the problem. I haven't installed anything. Does anyone know how to fix this or is this some kind of newly discovered radio bug?
Running on AT&T network.
Thanks

dont complain.. ur not stuck in H u now have full blown H in the area.. my girls 85 has full H now and so does my tilt

does this mean I have HSUPA too?
What exactly do you mean by full H? My download speeds didn't change at all

I am currently faced with this same stuck H issue.
I am running the stock AT&T ROM ver ... 1.62.502.0, Radio version 1.37.14.09
Sometimes when I travel to a particular work office I use dutty's 10 button Comm Manager to turn 3G off. This particular office is built like a fortress and I barely get signal inside. If I leave 3G on my battery is dead in a matter of hours.
So I turned 3G off for the first time since upgrading to this ROM, and later when I turned it back on I find I have a constant H indicator rather than the 3G I normally see.
Yes I am in an HSDPA area, but normally I would only see the H when downloading.
Yes, I use direct push with a hosted exchange server.
I've tried disabling HSDPA in KaiserTweak, and I get back to the 3G indicator ... But as you would expect my download speeds are limited to 300 to 400 kbit/sec.
With HSDPA enabled I average twice that, with bursts over 1mbit/sec.
Can anyone speculate why I have the constant H indicator now instead of only when downloading?
Everything still works, I just wouldn't mind knowing why I am seeing this change in indicator.

I have since found out that the the contant H icon is a result of AT&T upgrading their network. Since then, my download speeds have roughly doubled. Turns out the contant H is a good thing.

I went away on a business trip for a week and now upon returning I too am seeing the constant H, whereas previously I'd see 3G which would change to H and back when using data.
But that's not the part that is worrying me.
The problem I see is that the data connection is active all the time; it never drops. So besides the large H indicating HSDPA availability, once any data connection is made the 4 bars plus plus small triangle changes to 4 bars plus small H and *never* changes back. In the past I'm pretty sure the data connection would come and go as needed.
Is this bad at all? Seems like it would suck battery power to have the data connection active all the time. It's as if the KaiserTweak "always on: AT&T MediaNet" is stuck on (but I never actually did that tweak and it is actually disabled in KaiserTweak).
What's going on?

Have you done an upload speed test?
Apparently a constant H icon can indicate HSUPA support.

Little more info ... however finding a map of what was upgraded isn't that easy.

AT&T Nears HSPA
By Brad Smith
WirelessWeek - April 02, 2008
LAS VEGAS—AT&T will have all of its 3G markets enabled with the high speed uplink capabilities by the middle of the year, according to Hank Kafka, vice president of network architecture for the operator.
AT&T had 255 major metropolitan markets with W-CDMA/HSDPA at the end of 2007 and continues to add markets. Kafka said at a GSM Association roundtable on HSPA that AT&T expects to cover 350 markets with 3G by the end of 2008, including all of the top 100 markets.
The operator started installing HSUPA last year and now is in the process of rolling it out, he said. By mid-year, he said all of its 3G markets will have HSUPA. He says typical data rates on the downlink now are between 600-to-1400 Kbps with a peak of 3.6 Mbps, while the downlink typically is 500-to-800 Kbps.
There are upgrades for HSPA which take it as high as 14.4 Mbps and Kafka says AT&T is studying those. But he declined to say when or if AT&T will raise its data rates to those levels.
Kafka also said AT&T has seen significant data usage increases for customers using 3G.

Yea, I have the constant 'H' as well, but I think it's the same as having a constant 'E', meaning that you're connected to HSPA and everything's good.

switching bands
switched bands sometimes helps changing the icons from edge to 3g,to disable HSDPA you need to disable HSDPA through kaisertweak,schaps advancedconfig or hsdpa switch whether cooked into rom or manually installed to switch back to 3g

AT&T - indicator show H all the time

Before, indicator (G, E, 3G or H) show 3G and then phone make data call its shows H, but form today morning its stay H all the time
Any ideas?
p.s.
Im using new att rom 1.62

Chances are, your area has been upgraded to HSDPA coverage. My was a few months ago (NYC)

Thats correct. My icon is also on H now all time. (PHL)

Philly area
I live in this metro area myself. The H icon does mean HSDPA however you can set this off using Kaisertweak. Once you're phone resets it should go back to 3G icon. If you want to me more technical with switching bands, you can use the newer comm manager and advaned config to add a 3G on/off button for toggling between edge and 3G. Remember HSDPA is a faster form of 3G, the 3G icon just refers to the slower form of it which once was a default until the recent upgrade.

very wierd...i always have 3G turned off....so I'm always on EDGE...tonight i opened up the comm manager and turned 3G back on...now i have H at all times....
But! with the H or the 3G i get less signal strenght....on Edge i get full everywhere

EDGE data coverage is from the GSM side of the network.
The H is from the 3G side of the network. The technologies are different, and so is the coverage. The footprints are not exactly the same.
However, with 3G... you only need 1-2 bar to be able to place/receive phone calls. Voice quality should be reasonable.
Just an FYI.

oh...so what should i leave?
the EDGE or the H?
i dont have a data plan if that even matters

How do they fair up for battery life?
I hear that 3G uses less battery than EDGE does...is this true?
What about HSDPA?

Um, no you've got that backwards. Edge uses MUCH less battery than 3G and way less than HSDPA.
If you don't use data, stick with Edge.

but the H icon makes me feel special

PDX area just switched over to HSDPA a few days ago - I'm so happy!
To make things even better, then guy in the store dropped my plan down to $30 a month (no txt messages) which was unavailable when I first bought the phone! Sweet Deal!

Suddenly no 3g, always H?!

My carrier had some little problems during the past weeks, aparently they were working on something. I sometimes, for short periods, did not have data connection or no servic at all. Now the problems are gone and a speedtest today showed that at my home, the download speed went from an average 1 Mbit to over 5 Mbit!
However, the H symbol won't go away anymore! It used to switch to 3g when not data was transferred. I assume that this will influence battery life.
Is there anything I should be worried?

From what I recall, H is faster than 3g, as long as your in a good signal area, the H will always be visable, it will only drop down to 3g if the area your in has no H signal... and if there is no 3g it will drop to a 2g signal... simples, having the H does not meen that data is being transfered!

I am aware of the different speed levels, what I experience now is that the H symbol stays all the time, whereas it used to change to 3g when idling even in areas with very good reception...

Wait, I don't get what you're saying. Let me clear it up:
Very good reception = H
Not so good reception = 3G
You want to see H (means HSDPA which is a a type of 3G data, but it's faster).

Okay, I'll try that too!
I live in an area with very good reception and therefore the phone used to switch from 3g to H whenever data was transfered and back . Now, however, it stays on H all the time and does not switch back to 3g when no traffic occurs.
It is just a change in the pattern my phone behaves so I wanted to get some info on that...

Hi, it's your phone doing what it should by seeking the best signal.

H refers to HSDPA which is based on UMTS (3G). Consider it a 'turbo' version of 3G. It's sometimes also referred to as 3G+ because it's faster then 3G but not really 4G technology. The tower in your area most likely got upgraded to HSDPA that's why you don't see the 3G icon anymore.

Not correct, he mentioned that his phone was using H on demand before, so the capability was there already.
The problem is that H mode uses more battery than 3G, which is why it normally only switches to H during data transfers instead of continously being on.
Possibly your provider made a change which forces your phone to stay in H mode. On hardcores homepage (see speedmod kernel thread) he describes a method to manually deactivate H mode if you want to play with it.
Hope that helps.

seems to be the explanation... Suddenly I have ~6 Mbit, so almost unsurprisingly there had to be a catch
as for disabling H, it would be permanently so not quite an option. I guess, I'll have to live with it but nevertheless I'll call customer support..

Hspa and 3g are actually different technologies, but can be used on the same site and freq. If you have noticed that your phone is nowdays all the time showing H ( hspa ) and not in 3g like before it means that your carrier has expanded their hspa features and capacity of the network on that area. Main difference between these two tech is of course the speed and how network resources are shared between the users. In 3g you have dedicated ones, but speed limited and in hspa you are sharing the resources between other ones under that cell area. hspa is good if you are near by the cell and there is not too many users from battery consumption point of aswell from througput point of view, 3g is better if you are on the cell edge due to dedicated resources reserved only for you. Main point is, battery consumption of your phone depends mainly how you use your phone ,what kind of applications you have and how often those are connecting/contacted by the network.
Browsing in 3g sucks!

[Q] Stay on H+ rather than H connection

I have already disabled fast dormancy using *#9900# code in my Note, but now my phone switch between H and H+ icon. When connection is idel, it falls back to H. If I browse a webpage, it takes more than 10 seconds to connect to H+. And yes, H has no data trafic avalable. That means I have to wait the phone to change to H+ if I want to browse the internet.
Does anyone know how to stay with H+ icon?

OMG no one knows?

I think it depends on your rom..

It depends on your Network and rom + modem u using.
Post the details here and lets see what the community here can find.

Data works fine on H. It certainly seems faster on H+, but, as you say, the phone spends so long finding and connecting, the speed is wasted. I'd be happy to stay on H myself.
I agree, it would be nice to keep to one. My connection jumps from 3g to H to H+ and even to E, especially when moving on a train.

I think it is network dependent
E - Edge 2G
H - 3G
H+ - 3.5G
When you set your network mode to auto, it searches for faster avaiable network. If you set it to only WCDMA, you won't get E, but i think there is no setting to select 3G/3.5G.
Another problem to select WCDMA is, whenever any place dont have 3G coverage, your network will lost.

In germany it is also other:
G - gprs up to 56kpbs
E - edge up to 128kbps
3G - umts up 384 kbps
H - HSPA up to 14 mbps
H+ - extended hspa up to 21mbps
But H+ is only active when it is needed and it is all carrierer depending. If i am on H+ i can se my battery dying

It is network related there's nothing your phone can do about it.
H+ is actually using the 64QAM modulation over the air interface which gives you 50% more throughput ideally than H.
3G is up to 384kbps
H is up to 14.4Mbps (16QAM)
H+ is up to 21Mbps
The above is the throughput on the lower levels, so at the application level you will get around 10% less (and that's if you are alone using the base station and your carrier is not limiting your throughput)
Everything that goes through wireless interfaces has to be shared between users. Therefore, the network has to manage valuable and limited resources to serve everyone and provide a best effort service. In order to do that, idle users or users below a certain threshold will be down switched from H+ to H (this usually happens due to radio signal conditions) and to 3G. After that it kicks you back to idle mode, so even if it says H, your actually not connected until a new session is triggered and based on your needs and availability, you are up switched to a faster channel.
Depending on each country and their marketing:
2G
2.5G is GPRS (G)
2.75G is EDGE (E)
3G
3.5G is HSPA (H)
3.9G (4G in the US) is HSPA+
4G is LTE
Fast dormancy is a new feature on 3G networks (not available in most networks yet) that improves your switching between different channels (H+, H, 3G, idle, ....) and it has a major impact on your battery life and the speed of establishing a new data connection once you are idle. This is also controlled by your network. Anyway, some people believe that turning it off while it is not supported by your network can help improving battery life. Which I don't think is true, since by turning it off you are forcing your mobile to ignore this new feature (and if it doesn't exist there's nothing to ignore anyway) and turning it off shouldn't have any effect unless it is active on the network and your carrier is not managing it correctly.

There is a short code for turning off h+ my phone would always time out when trying to connect to h+ so disabled it. And it works great now, can't for the life of me remember what the short code is though!

Is there a code to turn on H+ too? Because my phone used to show H+ but now it only shows H although I have not changed any settings.

Force HSPA+ instead of 4G?

Does anyone know how to force the note 4 to use HSPA+ instead of 4G?
The reason why i ask is because in areas where i cannot get 4GLTE the note 4 goes into 4G and its basically unusable (~1mbps maybe, most of the time i cannot even perform a speed test) eventhough the 4G is with 5 bars. In the same exact area HSPA+ gets very good speeds of 6mbp+
To test this, i forced 4G on my note 4 at my house and got a 1mbps speed test. Before upgrading to the note 4 from t-mobile i had an old note 2 from verizon running H+ getting 6mbps+ at my home.
Update: i really think the note 4 or the modem is causing the issue. Testing again my my house. When i first force the 4G connection the speed test are horrible. (< 1 mbps). After some time it seems idling in 4G it seems i got pushed into H+ reframed?(but still 4g icon) and getting consistance 6mbps.
I also noticed that the note 4 drops LTE to 4G at 2 bars or so when LTE speeds is definitely present and running at 20mbps

Hspa+ shows as 4g. If you go to other network settings where the apn is you can select lte,wcdma, options. In remote areas my 4g speed is better than my lte . The lingo is kinda weird so every carrier has different definitions of 4g. Hspa+ is technically 3.5g lol.

The app Advanced Signal Status let's you choose your network type.
Install it from play store and lock it to what you want. Try phone calls and SMS for the modes you try because some modes will be data only.

I noticed this today at home. I forced it to WCDMA mode only, it took like 10 mins for it to eventually show "4G" at my home office. The signal and download speed were terrible when forced into WCDMA hspa mode+ (4G) . In the same room and home my Note 3 would get a very good signal this time last year when I used the Note 3.
Perhaps T mobile has done something to the cell site here? Or The Note 4 isnt working as it should?

Ive had the same issue. So i work in one city and live in another. So when i get to work my data is slooooow. I force it to 4g and after a while back to lte. Speeds are fine. Same thing happens when i get home. Tmo told me to just restart my phone but that doesnt always work

Same situation with me. LTE tower doesn't reach my room but I got 10mbps in my living room....and my room I get less than 1mbps and goes to lte to 4g often with very slow speeds. I even have a LTE booster which doesn't really help much with speed. Without the lte booster I get almost 0 signal in my room

I used to have same problem during lte upgrade in my area. On lte around 8+ up and down while on 4g speds were 15-20 down and less than 2 up. Ping times were longer on 4g. After upgrade I no longer need to switch between lte and 4g

But is T Mobile removing their 4G HSPA wcdma towers? I used to get a very good db signal in my office, now -115db at best for 4G in same location but band 4 700Mhz is now present? Any relationship between these ...

See the below screen shot. On that menu you can pick the non LTE function and force H+. You can also switch back to LTE.

Thanks I had already figured out how to.force a specific data connection , hence why that thread I posted was asking what the default option is, since I didn't write it down.
But back on subject, 4G next to non existent now at home after 700mhz band 12 availability.

What is UMTS? I never get Hspa+

I've found that my data is ridiculously slow (I'm talking edge speeds) when I turn WiFi off, even when I am in an area that gets a strong LTE signal. I feel like my device does not automatically connect to the best available tower; rather, it seems to try to latch on to whatever tower it was connected to before I connected to WiFi. Toggling "mobile data" off then on again seems to reconnect my device to the closer/better tower and the speed improves drastically. (It's possible that toggling airplane mode or network modes will do the same thing). When you are in an area that has poor LTE, you might consider keeping it off. Change the selection from “LTE/WCDMA/GSM” to just “WCDMA/GSM” and you'll be on the slower HSPA+ network (though, I believe it still shows the 4G icon). You can always change it back when you are in a better area.

4G is back up and running in my home location. Must have been temp disabled when they rolled out 700mhz band 12 LTE in my area.
