I was wondering if there was something I could download, or something from the market that i could download that would make my phone say H instead of 3G? My vibrant is not rooted.
I'm wondering why... but there won't be an app to do that. The G E and 3G icons are held in drawables. So unless you make your own update.zip with replaces drawables, I don't that's going to happen.

Why do you want it to display that? The H is generally displayed when you're using HSPA/HSPA+. If you're connected t 3G it will say 3G. If you're connected to Edge, you'll get an E and if you're on the barebones cell network all you get is the number of bars you have.

I think he wants his phone to be like nexus one is, or other android phones are running custom roms, specifically cyanogen mod. With cm, it will jump from 3g to h icon quite often when data is used, does it to me in my area. I get hspa speeds here, but 3g is the only icon displayed. I like it this way more, the constant jump from 3g to hspa in notifications pane is annoying. Maybe he just wants people to see that his phone is on hspa and not 3g, because the icon doesn't change to that on stock rom.
I remember the first time my g1 said h... Had to call a buddy with a g1 and had to find an i*hone to make jealous...
Its worth bragging about...

Not true. I have a stock rom on my Vibrant and it does toggle between 3g and hybrid. It just depends on whether or not you have the new radios broadcasting in your area. Some markets have a lot of hybrid running, while many others have little to none. One of my best friends is an RF tech for T-Mo.
Haha "H" doesn't stand for "Hybrid"

No ****, Einstein! It stands for HSDPA, but ask any switch tech and he will tell you its hybrid. Right now in many markets, it is a true hybrid mix of HSDPA and 3g and not explicitly one or the other. Do some research before you criticize someone, retard!

I downloaded the user manual to the vibrant (not the one that comes in the box) and it definitely says that there is a 'H' icon. I wonder why they don't have it displayed when actually connected to a HSDPA+ connection?
This is the text next to the 'H' Icons:
Displays when the 3G+ network connection is active.
Displays when your phone is communicating with the
3G+ network.
What does it mean when there's just a G?
3G means 3G
E means EDGE
H means Hybrid/HSPA or whatever. I was out of town last weekend, and noticed that it was just a G.

Hello all - I don't know if there's any answer to this or not but thought I'd throw it out there. I updated Android myself to 2.1 since apparently AT&T doesn't feel the need to. That has been a fine experience and I've experience nothing negative aside from the wireless network speed. My phone now always has the H (for HSDPA from what I understand) instead of of 3G, but downloads, web browsing, and YouTube are all way slower than they were before. It takes 10 - 15 seconds to download a 750k app usually. I have ran the speed test app from speedtest.net and its results confirm this by showing 44 kbps downstream & 750 kbps upstream speeds.
Is there anything I can do to fix this? I know that HSDPA is supposed to be faster than 3G but this is unbearable - I am almost tempted to use EDGE exclusively because that is all I pick up at home (EDGE service that is) and I get better performance when using the browser than I do with HSDPA (although that is probably more mental than anything since when on HSDPA I am sitting there staring at the phone thinking "What is taking so long!" and when on EDGE I choose something and then don't worry about it for a few because I know it will take some time.
Thanks for any advice!

This is probably a network coverage issue and nothing you can do about it from a phone standpoint.
Ha! I love the first response had a joker pic because I was thinking of the joker when I wrote "why so sloooow".
Anyways when you say coverage what do you mean precisely? do you simply mean at&t hasnt done enough in my area for hsdpa to be effective? I do always have a full 4 bars of strength on it pretty much.
Thanks!

Yes, I mean AT&T. Having four bars means that you have a good signal. It does not indicate however how much bandwidth AT&T has allocated to that particular area/tower.
Think of it like a wireless router at home or office. On your laptop or computer, you see that you have a strong WiFi signal but, that does not mean that you have a fast connection as that depends on your DSL/cable connection.
Get my point?
Got it, that's what I feared. So in essence by improving my phone with 2.1 I screwed my phone (currently) with hsdpa

No, it did not screw your phone. Your phone is innocent here. It is probably the network. AT&T may have a problem in that area. Did you try the speed somewhere else?
Nope, haven't tried it anywhere else. I didn't mean screw my phone, what I, meant was if at&t is not so good with hsdpa in my area I am stuck with those speeds until that is resolved because I can't force 3g (my speed when I had iphone 3g was usually around 1 mbps)

I am on att also with the 2.1, luckily im in an area where i get around 2mb/2mb sometimes faster, sometimes slower. Did you try the setting in wirelessnetworks/mobile networks/network mode/ tick wcdma only if not on H. could help not sure, just a thought.

Your phone automatically switches between H/3G/E where available. I also have AT&T and have debranded my phone and did not notice any lag.
your problem is AT&T.
H is higher than 3G. if you got problems with it it`s because the signal is strong enough to use H but it preforms worse than 3G (cunfusing ah?!)
Well I was outside of my town the other day, in the country and noticed I was in hsdpa somehow so I ran a test and out there I was getting on average about 3.7 mbps. I guess where I am most of the time just isn't an optimal spot. Thanks all for the responses!

http://en.wikipedia.org/wiki/Umts - when the icon shows 3G this is what it shows
http://en.wikipedia.org/wiki/HSPDA - when the icon shows H
HSPDA is able to provide faster speeds, but I believe it's highly dependent on how strong your signal is
Not sure myself, but if you're on Tmobile or ATT it pribably stands for HSDPA. 3G would mean WCDMA I believe.
Sent from my Vibrant using XDA App, Bionix-v 1.21
Long story short... it depends on how the ROM has been programmed to display what protocol your phone is using for data traffic.
3G just means regular UMTS 3G data
H means that it is is using HSPA, a faster protocol for UMTS 3G.
It doesn't mean that you're taking advantage of the faster speeds... that is dependent upon a slew of other factors.
Just to clear some things up. 3G is an all encompassing term, that INCLUDES the following technologies:
UMTS
HS(D/U)PA(+)
W-CDMA
EV-DO Rev 0/A/B
LTE
WiMax
As noted in the post immediately above me, the symbol it shows, depends on how the rom was customised to show each icon for the corresponding protocol.
If you don't believe me, that's cool, but go look at the ITU declinations on what is and is not 3g. There is no 4G CDMA technology. Pure CDMA is dead in the long run. All the current 3G GSM technologies, use the WCDMA or OFDMA air interface.
OFDM is not 3G

This is false. WiMax uses OFDM and LTE uses OFDMA (the same, but for multi-user as opposed to single). WiMax as 802.16e is NOT 4g. Neither is anything currently available and anything being deployed in the next 2-3 years.
I didn't say it was 4G. I said that OFDM was not 3G.
It isn't. Taking the broad view, its pretty clear to me that code div mult access is what differentiates 3G from its predecessors.
With 4G it will be orthogonal frequency
Here's a mathematical formula that pertains to all Vibrant ROMS that use an H and/or 3G
3G = H
The answer is, there is no difference except for the way they look. Both are really only using 3g.
The phone switches from hsdpa to umts back and forth all day according to how you use the internet. It automatically switches from hsdpa to umts when it is not browsing the web. That is-- if you live in an area with hsdpa. In which case it would stay on umts all day. Which would make your battery pretty happy. My battery hates hsdpa

This is false. Your phone jumps on the preferred network. Usually, unless you have specified, it sits on the fastest preferred network available. As such, battery consumption improves when you disable 3g (which is HSPA AND UMTS).

If it's not 3g then what is it? OFDM is used on both current 3g and future 4g (LTE-Advanced) systems.

hi there,
I believe what you say and if it is just a matter in which the ROM is programmed, why does my stupid S3 still switches from H+ to 3g?
I dont know and I cant tell if either of the two is faster than the other, but it is annyoing the constant switching

H+ = HSPA+ = 3g. There are different names for the different 3g evolutions and technologies, but they are still 3g. It keeps hopping between the networks because you're unfortunately in an area with bad coverage for the faster network.
AT&T is secretly throttling all of its smartphone customers during phone calls. This was tested on several devices including the Galaxy Note.

I noticed this the other day as well. I don't use data very often whole on a call, and when i noticed the slower speeds, I attributed it to where i was.
If this is true, its yet another reason to start hating on AT&T!!

Yeah it's really noticeable when you do something try to send a picture message while on the phone. The upload speed is just crazy low.
No throtling being done here. From my understanding during a phone call lte simply cannot be used in conjunction with voice calling, so the LTE radio is turned off and voice is sent over hspa+(or whatever other bands its using) and data switches to HSPA+. So not neccesarily intentional throttling per say, just hardware and technological limitations. Once VoLTE is more common practice I'm sure this will change.

That's not really true. If it were then the faster the connection you have, the faster your on call connection would be. If what you were saying was true then when I'm in an area that gets 9 megs during a call, I should get better on-call data speeds than if I was in an area with 2 megs. Instead regardless of if I'm in a 9 meg or 2 meg area, my data speeds during a call still instantly drop down to around 1 meg and the upload ALWAYS goes down to the 20k area (even if I'm in an area that gives me over 2 megs of upload. BTW, it wasn't always like this either. It isn't a limitation of technology, it's a limitation placed by AT&T, most likely to save spectrum. The crazy thing to me is they air these talk and surf commercials but you can barely do it now. If you compare it to Tmobile, it's like night and day.
I saw that the other day when I was on a call. Thought I was just in a bad area. Just tested on my coworkers note while he's on a call, same thing. Lame.

How is it a hardware and technology limitation if the SAME PHONES perform DIFFERENTLY on different networks using the same technology?
Ok some of you guys really need to research more about how AT&T's 4G lte network works lol,Lte is purely for data so when not on a call the phone will sit on the lte band but the moment you make or receive a call the network hands off the phone to a hspa, hspa+ or edge (connection if the other 2 3g connections hspa or hspa+ is not available) . Once the call is done the phone should switch back to the preferred lte connection. Currently not being able to make voice calls over lte is a limitation by the tech, once voice over ip is ready to be implemented on lte then we're good to go.
Sent from my SAMSUNG-SGH-I727 using xda premium
I can confirm this on my Note. I thought it was just an odd quirk for me but I'm partially glad to hear it affects everyone. On my old HSPA phone I could maintain 2-3 Gbps at home even while on a call - useful for work so I could be on a conference call while also remoting to my work computer's desktop. Now when I'm on a voice call the data connection becomes nearly useless. I may have to switch back to my old phone next time I need to do this - which is ridiculous!
So even if a phone call does force you onto HSPA, they are still throttling you far below the available bandwidth.

This issue has nothing to do with LTE though. I know I saw someone earlier in the thread bring it up, but that has no bearing on what we're experiencing.
I noticed the same thing as well last week when I would make calls. LTE shuts off, 4G kicks in for calls. Hang up, LTE turns back on. Just like Verizon's no data while talking its simply a hardware limitation on the network for now.

From what I've experienced it goes beyond just kicking you down to the HSPA network.
They definitely changed this. Tested this extensively when the skyrocket came out
The hardware is not capable of both seperate radios operating at the same time and voice over lte has not been implemented.
Plain and simple.
When you make a call the lte radio goes idle. The hspa (3g and hspa+) radio activates
Speeds during call should be the equivelant of speeds achieved with a 3g phone...like we confirmed with a gs2 Back then
Now though
Slow speeds while on a call
tested 3g speeds...added the phone apn and select it. It may or may not work but if it works it will lock you onto 3g briefly enough to do a speed test. Compare that to your in call tests. or use a 3g only phone To get a comparison test IN REAL TIME
Technically att could begin throttling but it could be network issues as well.

That's what I was talking about. I could live with a fallback to HSPA until they implement voice on LTE, but the results are much slower than that.

Perhaps YOU should do a little more research...I assure you I am not a ROOKIE when it comes to these things. I have known for a fact that people were able to surf and talk on AT&T's network in the past without any problems. Now internet is practically UNUSABLE while on a call. Pages wont even load. There is something very underhanded going on.
Even by your own statement the phone should revert to 3g speeds while a call is being placed so why are speeds equivalent to EDGE/Dial Up when people have adequate signal strenght?
Ever since I've transferred to AT&T I've had laggy data issues. I finally rooted/flashed to AOKP, and while trying to address the issues of no APNs appearing or saving and no signal status in the status bar, I've come to find both AT&T and T-Mobile as Available Networks under some network setting. Am I chasing ghosts here, or is there something actually up?
EDIT: So I really need help troubleshooting the issue. I'll logcat, dump, or whatever necessary. I've been in many cities/areas and this problem persists: if I haven't used data or the phone hasn't been backgrounding traffic, it'll take anywhere from 5 to 30 seconds before a connection is made when I try to access an internet-related function on my phone (even though 3G/H is displayed in the status bar). Out of shear frustration (this has been happening since I got the phone, under stock ROMs and now under AOKP), I tried messing with *#*#info#*#*. I changed WCDMA-preferred to WCDMA-only -- no improvement. Oddly, I also tried GSM-only. Well, great improvement! Even though I only have E, there is absolutely no latency in waiting for a connection -- so pages and other data end up loading faster on Edge than 3G !
I have absolutely no idea why my phone takes forever to make a connection. Under 3G, I see only but a few upstream network activity blips (even under full bars) for as much as 30 seconds, before there is any downstream activity (and when it comes, it comes). Can anyone help???
P.S.: I'm going to try using a friend's SIM later for comparison.

I finally rooted/flashed to AOKP, and while trying to address the issues of no APNs appearing or saving and no signal status in the status bar, I've come to find both AT&T and T-Mobile as Available Networks under some network setting. Am I chasing ghosts here, or is there something actually up?

Because they both share the 1900MHz band I believe.

I'd like to know if it shows up for anyone else?

On AOKP it does for me too. Just ignore it.

An aside: does your phone stay on 3G and switch to H only under moderate network traffic?

The phone displays 3G because thats what it is... then when data is being processed, it shows H because its using the "what AT&T calls 4G but its really HSPA" side of the network. For just standby time with no data, its going to show 3G because HSDPA is traffic, not standby.

Well that's strange. I'm used to phones displaying what network-level they are capable of. So why would it not just display H for HSPA+ when HSPA+ service is available, instead of only displaying under traffic.
I'm going to go ahead an edit this thread to help troubleshoot what I think to be the main issue.
After some trials I see that the network indicator switches back and forth between 3G and H a few tines before making the connection and transmitting data. Hmmm...
Basically, "4G" will eat your battery alive so the phone idles at 3G and jumps to H+ only when you use data. If you were on a "stock" ATT rom it would always read H+, but this is technically false since when its idle the phone sits in 3G. CM9 and AOKP accurately display it which is why you see the switch.

I have a HTC Amaze for a phone and the Galaxy S2 is my media player. Sometimes, when I don't feel like carrying around two devices, I put my T-Mobile SIM in the galaxy and use it as my phone. I must say, Edge is not as slow as I remember it being. Maybe speed is contingent on network traffic. If thats the case, instead of using crowded "faux G" networks, I may defer to Edge to save battery life and get good dl/ul rates.
My phone does the same thing. I noticed it sometime ago. When idle 3g. Internet I get H+. This is with both Shostock2 and Phone Bricker. I was curious to know too but just blew it off because it really doesnt make any difference to me as long as Im getting decent speeds. Im not even with ATT anymore. Went with Straight Talk. Which uses ATT towers. Cant beat the price!!
They don't have the correct apns, but that symbol problem is because the phone doesn't use hspa+ passively, only actively. It causes some lag when downloading, but it is faster fit large data. But your problem is due to a supposed imei range with bad modems. Rehash stick, fix the triangle, and return it.
