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

Strange LTE / 4G issues HTC One T-Mobile

My T-Mobile speeds are pretty good. According to speed test pointing to the same server my speeds for the last few months were
4g (non-lte) up to 15 down, up to 5 up
LTE 35-50 down, 20-25 up
Yesterday I had issues with LTE, it was around 5 down. I thought too many people must have gotten T-Mobile in my area
Then I tested it again at night, same deal. I switched to 4g hspa (GSM\WCDMA Auto) and my download was crazy fast, up to 25mbps, while up was still under 5. Then I tried switching back to LTE (GSM\WCDMA\LTE Auto), but the icon wouldn't change to LTE. My samsung sitting a few inches away was showing LTE, but I didn't test samsung because it has used all high speed data. I rebooted the phone, still showed 4G, not LTE. Then I pulled the sim out of HTC One and put it in Nexus 5 - Nexus showed LTE right away and tested at over 35mbps. Put back into HTC One - this time LTE showed up, but speeds were still less than 5. (I did all tests at exact same place, with the phones laying in the same spot on the desk). I called T-Mobile tech support - no help
Then I took HTC One closer to the window, and speed went up to 30. Put it back on the same spot on the desk and speeds are fine, over 30. Tested 4g hspa - under 15. Today, speeds are up to 50, while 4g hspa again under 15.
What's the deal? Did T-Mobile guy do something? Hardware issue with my HTC One?
To summarize:
1. When LTE on HTC One was very slow, HSPA was very fast and Nexus 5 LTE was very fast (I didn't not test Nexus hspa unfortunately)
2, When switching from LTE to 4g hspa, switching back didn't work. Rebooting didn't help either. Trying the same thing today - it works but takes a while. I noticed if I switch from 4g hspa to LTE and then switch wifi ON and then OFF, LTE comes back right away. But without toggling WIFI it takes over a minute.
3. One other interesting thing - when I place a call LTE switches to 4g. After you hang up it switches to LTE, BUT -
On HTC One - it switches right away!!
On Samsung - always takes a little time. maybe even over a minute
On Nexus 5 - sometimes a few seconds, other times up 5 minutes!!!!
Why HTC One is able to switch to LTE right away, while Nexus 5 may take up to 5 minutes? is there an easy way (via some program) to force Nexus and Samsung to switch right away?
Thanks.
P.S. Another issue with HTC One - wifi is much weaker when further away from the router. I'd get 5mbps where Nexus 5 and Samsung would get 15-20. I had same issue with my previous nexus 5 but my new nexus 5 seems to be much better on wifi now. I know it has a lot to do with the router and replacing the router may fix the issue, BUT from my experience phones that aren't ok with home router may not be OK with public wifi either. I tested the public wifi with my old nexus 5, it was 30-50% slower than samsung.

D5803 AT&T LTE sticking on 1700mhz when 700mhz is available

Loving my Z3c so far, but I'm having one weird issue.
My APN settings are correct and I'm getting LTE, but I noticed that I was only getting two bars at home and my dBm was super high compared to my other phones (I normally get full bars with every AT&T phone at home). I rebooted the phone and it came back at full bars, with a really low dBm. Today, I went to work and after I came home, it was down to two bars again with a high dBm. I toggled mobile data off and on and it returned to full bars and low dBm.
Here's what I THINK is happening: I believe that at home, it gets on the 700mhZ LTE network and all is fine, but at work, it gets on 1700. Then it gets stuck on 1700mhz and stays that way until I toggle the connection off/on. It still gets LTE and decent speeds, but the dBm is high and the bars are low. I don't have any other phones that do this.
Does anyone know if there's a way to disable certain bands. On the LG G3, you can turn off LTE bands that you don't want in the phone menu. I'm wondering if there's a way to disable 1700 so this won't happen. Also wondering if anyone else on AT&T is experiencing this. I'm stock, not rooted.
Thanks!

5.1 giving better radio signal?

I have noticed that with 5.1 while I normally got just 1-2 bars at home of signal I am now getting 3-4 and better speeds. At first I thought I was now getting Band 12(tmobile) but LTE Discovery says that I'm still on Band 4.
Anyone else seeing this?

When I am in a very weak signal area, I am definitely getting a better LTE signal. But voice/calling (GSM) is worse on AT&T. Where I could make a call previously, on a very weak signal, now I get nothing.

Just finished flashing 5.1 and setting it up - and I'm definitely getting higher single indicators for LTE now (T-mobile Band 4) - I rarely used to get 1 bar in my house, but now it constantly shows 2-3 bars. Whether the coverage is actually improved is yet to be determined...

5.1 is definitely giving me a better radio signal in my house as I usually only had 0 to 1 bars. Now i'm getting 3 to 4 bars and my messages are sending without without delay now. I'm on AT&t.

Not for me!

I'm getting better "signal" on 5.1 (more bars) However my lte speeds are horrible now Was 15-20 mbps and now its consistently 3-5 mbps on Tmobile.

Indicators can be changed to always look good. Actual signal probably didn't change.

This.
Its showing 3-4 bars of LTE in my house now, where before lucky to have 1.
But dbms are literally the same for me at least.
At work, inside thick concrete walls, inside of more thick concrete walls...I used to be able to keep a solid 4G signal. Now it barely keeps connected, and when it does it never goes off of EDGE. I'm on TMO btw.
I think I'll be switching back to the last radio. Not impressed with this new one from the 5.1 update.

Another thought is the transition from LTE to HSPA might be improved. I wasn't able to make a phone call in my basement at my desk. Now after the 5.1 update I was able to call and hold a conversation in the same spot.

The 47E radio is the best radio so far (for me at least).

T-Mobile speeds = ugh on the LTE International (T705)

Dangit, just got my T705 in today from Amazon.
Promptly inserted my Note 4's SIM into it (LTE SIM) and ugh... haven't managed to get past 1.3Mbps download speeds yet.
Tried another APN from the thread below but still no luck.
https://forums.oneplus.net/threads/guide-how-to-make-lte-faster-and-fixes-for-your-problems.77304/
I knew the T705 (verified Exynos) probably wouldn't have the 4G LTE bands for T-Mobile but sheesh, 3G should be faster than 1.3Mbps!!!!

I updated my TouchWiz to the latest and had the same poor speeds.
Then I installed a couple different modems, all with same slow, ~1Mbps speeds.
Tried some different APN settings I found here and there. No change in problem.
Then I installed this CM12 ROM and now I have ~5.5Mbps down and ~2Mbps up which is more along the lines of what I was expecting to see for 3G (at the location where I'm at in my city).
I'll probably get even better speeds once I'm downtown.

Okay, I'm happy now. :good:
Could not get LTE but I knew I probably wouldn't. That's most likely some hardware limitation.

what speed do you get on 3G on your note? You can make it use 3G only in the settings. Problem is everyone is on 3G, some are on 4G so the contention is huge. Have the same issue where I live but my Tab S is no worse than my S5.

Took the Tab down to T-Mobile and got it onto my data plan and they put a new MicroSIM in it, gave it a phone # (which cannot call or be called) and configured my APN.
Still only getting about 5-6 down at my house but I did hit 16 mbps download in the city. While my Note 4 on LTE got 34 download at the same location.
16 is plenty for Pandora/etc.
