does the g2x even have a 3g indicator icon?

ive noticed that i get a 4g and a 2g icon but wheres the 3g icon? has anyone seened it?

Travling through the middle of nowhere over the last 3 days I've seen, no signal, G, 2G, 3G, & 4G. It's there.

I also have not seen the 3G icon. I drive through the city and would think when I get out if 4G I would at least still be in a 3G area. Wonder if something may be wrong....

Same here but this is the first 4G device I have had and I know for a fact most of my city is covered by 4G. What is also weird is that in areas where I would have 1 or 2 bars with my Vibrant, it is telling me I have full bars worth of 4G with the G2X.

its there in the framwork i checked..
Im just wondering why it doesnt display 3G when its on UMTS... it sticks to 4G all the time...

very strange in the instruction manual it also shows 3g icon!

A lot of this has to do with the fact that T-Mobile's 3G towers == their 4G towers so if you're in an area where all of their towers have been upgraded to HSPA+ you will NEVER show 3G because you're always on a 4G tower. The only time you will show a 3G signal is if you're in an older area where they have pre-HSPA+ upgradeable towers. This is how T-mobile can say they have the biggest 4G network because almost all of their old HSPA/3G equipment has been turned into 4G equipment via software upgrades.

I have had my g2x for about 5 days and all I ever see is 4G or E never 3g. I have been checking in the settings/about phone/status and even when the phone is showing 3-4 bars of 4G it is still on umts. In the exact same location and within a minute or so when checking it with my Vibrant I will have 3 bars of H or 3G and in status it shows as hspda or hspda+. What is that about? I have checked this out at least 6 to 7 times a day and it is always the same only umts on the G2X and Hspda or Hspda+ on the Vibrant. I called CS and they wanted to send out another G2X I reluctantly said yes. I do really like this phone and will try to be patient but the device I have now has multiple issues. I am going to take the stance that this is an isolated case and the new one will be golden!!!

This is true. There's pretty much no need for a '3G' icon. Though, technically, it's debatable whether or not T-Mo's (or any other carriers) offerings right now are actually '4G' (according to the standards committees that define those things), but that's a different argument
tl;dr: T-Mo's 3G and 4G operate on pretty much the same technology, so if you're in an area where there was 3G, you'll probably have 4G. It doesn't need to switch back and forth or be toggled like the other solutions (looking at you Wi-Max)

[Q] Data speeds?

So I know all the issues with older 2g sims affecting speeds, I called tmobile, and they said that I was in fact registered with a 2g sim, so I had them activate the sim that came in the box, but I have no improvement in speed. I'm still getting nowhere above 2mbps, most of the time around 1. I know I have a 4g data plan, they added that when I got the phone for immediate activation, not next billing cycle. Even in areas where my old mytouch 3G slide got 4 mbps on the 3G HSPA network, I can't get much above 2 on the HSPA+ network. What gives? If the new 4g sim and data plan aren't working, what's the issue here? Anyone else having issues?

Are you sure that you're connected to HSPA+? And, even if you are connected with good reception to a HSPA+ tower, that doesn't mean that the tower has good bandwidth backhaul. If its a low traffic tower, T-Mobile might not want to pay for a large amount of bandwidth for it.

I suppose I can't be positive, but the icon says 4G. Although I've never seen a 3G icon, only G, 2G, and 4G, meaning they probably just replaced the 3G icon with the 4G icon since the phone can't technically display a different icon for HSPA and HSPA+, can it? I've never seen a 3G icon so I might just be connected to 3G. But even in populous areas, like downtown, at night, I top out at 4, MAYBE 5 mbps. I've heard people getting 4 or 5 on a bad day, 7-8 average and 10-12 if they're lucky. I'm wondering where that's at, maybe it's a flaw in the stock rom and an AOSP or other custom rom would be better. I seem to remember having bad speeds on sense on my Slide too.
During data transfer, I went to the about phone>network menu, and mobile network type reads HSDPA and then reverts to UMTS after a period of inactivity. It does not specify HSDPA+ though, it just says HSDPA. I understand that the 3g and 4g networks on tmobile are technically one and the same, HSDPA+ is just an advancement of the 3G technology, but I'm wondering if something just isn't clicking and the phone isn't taking advantage of HSDPA+. I checked the coverage map, and the entire region I live in, minus a few rural areas, are supposed to be covered by 4G data.

4G On My Skyrocket Finally Working BUT........

Ok...i added the Blaze Radio Mod to my Stock 4.0.4 Firmware on my Skyrocket. All went good. I see a 4G now. BUT...theres no bars in the signal. Why is this? And when i do the speed test now...keep saying try again. Ok...just now as im typing this...i changed the WCDMA to 1700....an now the speedtest gave me 3.00 Mbps download and 0.49 upload. But only 1 bar in my signal. Any way at all to improve that? I know my bar was more then that when i had edge or my other 3G phone. Let me know something if your reading this....and thanks.
THANKS TO ALL YOU GUYS ON HERE THAT REPLIED TO MY COMMENTS TO HELP. ILL TRY TO GIVE THANKS TO ALL OF YOU. THANKS AGAIN.

so on at&t uclf6 you were not getting 4G LTE? i have had no problems... i would not recommend using the blaze radio as it just never worked as well for me. have you tried some of the other ics radios? there are a bunch floating around. good luck

No i havent. People seem to be saying Blaze's Mod one is the only or at least best one. I mean...the 4G is there.....but no signal bars. Why would that be tho?
Oh..its unlocked using T Mobile now. If that helps.

I suspect the signal meter with with blaze mod is not that accurate. I routinely get in the a high percentage under cell standby time without signal, even in areas I know I have service. These are areas I spend multiple hours at a time at making and receiving calls.

Man..i dont know. Something is funny with this. When i turn my WiFi off....the 4G comes on...no signal bars...Market take a while to load. Few apps even timed out. And i KNOW im in a good coverage area. Is the Blaze Mod radio actually the best one? Is there others to use for us thats unlocked using T Mobile?

By saying 4G do you mean LTE or HSPA+?

It just shows 4G at the top. Is there another symbol? In my settings...about phone....it says Mobile Network Type:UMTS:3. I did see HSPA earlier for a bit. Guess i still have some fiddling to do. Wonder if there is another Radio that may give me more Bars. Mine shows 1 or none. But has the 4G symbol.

on skyrocket 4G isn't actually 4G it shows it when your connected to HSPA and I think also GSM not sure about the latter.
When your connected to LTE it will show 4G LTE.
Also by choosing WCDMA your actually choosing HSPA or at least that's how it looks to me.
Try different radios before working by stuff you read people say, each phone has different hardware, everyone leaves in different areas and thus each modem works differently for different people.
Also download network signal app from the market and check your dbm which means your reception, you can't count on bars because it's programmed differently for each modem -65 dmb and lower(or higher if your a match freak) is excellent -65 to -75 is good and the close it is to -100 is the worse reception you have.

Hmmm. True. Man..im tired of swapping all these Radios. Wanna find one that works decent at least. Some people say they get 1 to no bars in the house like i do. Then go outside an get 3 Bars. Im gonna download that Signal app. Sounds very interesting. I have it on LTE in the *#2263* now. Let me try the signal thing. Thanks man.
[Edit] Love the Network Signal Info Pro. Even tho its showing a frown for my mobile. But WiFi really good. I saw some Network Signal Boosters. I mean...do those really work if anyone know? Tried 2...didnt really see anything.

[Q] Why no 4g?

Well the name of the phone is the samsung infuse 4g. My phone is rooted running CM10. And for some reason, since I got it, it has always run on 3g (or some other network). Is it an additional service to pay for to get 4g? I have AT&T

It is not true 4g even though it is in the name.... AT&T calls it something like 3g+ with enhanced backhaul.

By editing a few image files, I can make your phone show that it's running on a 6g+ network.
The rom that you are using is probably showing closer to the real connection that you'really getting.

Exactly as both have said...infuse doesn't have real 4G...it has H+ which like pony said said is more like 3G+
And with a simple edit to the framework-res you can make it display whatever you want...doesn't mean you will actually
Have it but it will be displayed...back in the gb days I ditched out the h+ icon for a 4glte icon so the phone displayed 4g LTE even though it was on H+
Cyanogenmod only displays up to H. They also have a more accurate service "detector"

like they said. the infuse has faux-g not 4g. atleast not lte 4g. bassically att has had umts with hspa for a while which is technically 3g+ or 3.5 g in othe rcountries. att just decided to advertise it all as 3g so that they can say they have the fastest 3g network with a huge 3g coverage map even if the area didn't have the hspa aspect of it working instead of a huge 3g map and a small 3.5 g map. then they came out with hspa+ with "enhanced backhaul" which now things get confusing do they call it 3g++? or 3.75g? nope some government agency decide that since we have different technologies running on different networks 4g is not a definition of service type but as long as the theoretical speed is above 10mbps or something they can advertise 4g. so att does, they just put a little disclaimer in the fine print "4g speeds made availible through hspa+ with enhanced backhaul"
well the infuse takes this a step further in the factory firmware and doesn't report 3g, hspa and hspa+ as seperate connection statuses. it just assumes h+ anytime you have a umts connection.
so basically you've been lied to by your phone and deceived by marketing practices. all the cell companies deceive. they select the information that makes the look best and only show you that.

Its LTE not 4g. That's why it usually says H+ instead of 4g
Either way 850KB/s is enough for me. (Sorry for the weird picture my screen is 160dpi)
P.s. my GPS didn't lock in time. I'm in Sacramento and the server is 3000 miles away in Florida. (350 ping)

T-mobile LTE N4 vs N5

I just helped my son install the hybrid modem for his Nexus 4 and set up the T-mobile APN for it. I was about to tell him that he would have to go somewhere else to test it since I never get LTE at home, and then boom, the 4G icon shows up on his phone! I checked Network Signal Info and sure enough, it's got an LTE connection with about 6Mbps transfer rate. Sitting right next to him my N5 has only 3G with occasional switches up to HSPA and back, and a very low transfer rate. What gives? I am able to get LTE on the N5 in other areas of town and it works wonderfully, but around my home it is very weak and almost never runs in LTE mode.
Could it be that the N4 is connecting on a different LTE band? If so, why is the N5 not using that band as well? Is there something that can be done for the N5 to tweak it to improve its LTE reception or how it chooses how to connect to available LTE signals?

Both N4 and N5 have 1700 band so it should get perfect HSDPA.
It might be the towers in your area are busy or the signal is weak.
I use straight talk t-mobil and I get HSDPA around 15Mbps and my friend get a little more on LTE here in chicagoland.
Also for people on Straight talk if you want to get LTE att version you need to get a new simcard and change APN and for t-mobil
just get a new simcard and boom you get LTE.

Idk if I'd worry about it. In most places the HSDPA speeds for T-Mobile are the same or better than the LTE speeds you would get. I'm in the far north chicago suburbs and I get LTE and HSDPA downloads at 25mbps. The LTE coverage is still a bit spotty. Its probably only worth it if I you're in a developed urban area. However it is a bit strange that you guys have the same hardware, service and location but different connections. The only thing I can think of is that I've seen some people instruct to setup the apn as fast.tmobile.com. however mine only worked with fast.T-Mobile.com (with the dash). I would also check to confirm that your phone is set to lte preferred (LTE/gsm) and not gsm priority. Those are the only things I can think that I can think of. Hope it helps.

T-Mobile 4G LTE will properly works on fast.t-mobile.com, fast.tmobile.com is not the proper APN (the - matters)
There are just way too many variables. Maybe his modem has better reception, newer sim card, etc.

Fwiw there are other threads where people have reported that the N4 picks up LTE in the same place that an N5 does not. So you are not alone. N4 may have a stronger radio. That would be unfortunate... Never good to see a step backwards on something as important as that.

Good news everyone! I too has having this problem. My Nexus 4 was an LTE champ and then it was a huge let down that my Nexus 5 was treating LTE like it had cooties, but now my Nexus 5 works the way it should. What I did was go to my nearest T-Mobile store and told the representative what was happening. He called tech support and they ended up doing some sort of reset to my account. I also had questions about my SIM card and felt that it could have been at fault. He offered to switch it out to the new ISIS SIM and as soon as my phone booted up, it was on LTE. Since then, it has behaved like my Nexus 4. I am even in my office where the Nexus 5 wasn't picking up LTE, but my Nexus 4 was, and it is on LTE at the moment.
I am not sure if the reset that tech support did solved the problem or the new SIM, but I would definately give that a try--it didn't cost me anything and now I am happy with my Nexus 5. Good luck!

In my experience my N4 has slightly better signal pickup than my N5.
The real reason is probably differences in the radios' priority algorithms. Set your N5 to LTE-only and see what happens, I imagine you'll get LTE.

Did you not get LTE at all, or really poor LTE signal/speed?

I would get LTE eventually only to lose it when it reached 2 bars or lower. It was really weird. I would be in areas where one would get 5 bars of LTE and the phone would sit on HSPA until I would show the phone it was on LTE by switching to LTE Only under the secret dialer menu and then back to GSM/LTE (if you use LTE only, you will lose voice). Then it would hold LTE until it reached 1-2 bars and then go back to HSPA.
I hope this helps.

I am seeing strange readings of signal strength. I see a 10+ db difference between what is reported in the phone status and an app like rootmetrics.
I don't know which one is misrepresenting the signal strength but it seems the roometrics is more accurate because my nexus 4 the signal strength is roughly the same on lte.
Can anyone else confirm?
