I am wondering if there is way for me to shut down the 4G service on my amaze and have 3G instead. I know on some android phones it is possible. signal drops on 4G is really pissing me off

if it drops 4g it should automatically switch to 3g, if its not, its either cause you have no data reception at all at the time, or you have a screwed up phone, probably not the latter. There are some toggle apps you can look into on the market though, elixir is really good, and beautiful widgets has a 4g toggle i believe as well... hope this helps ya...
I'm using LTE switch. cuts it down too 4G

the LTE switch works for HSPA+?
It's kicking my phone down too and showing 2G and after running a speed test it's like 200kbps. I haven't really tried to kick it over to 3G.

Your choices are 2G or 3G/4G. The 3G and 4G signals are essentially the same, both WCDMA. This is why you don't see a 3G icon, it is all wrapped into the 4G icon.
If you want to stop 4G data, you can download the widget from the market or go to Settings > Wireless & Networks >Mobile Networks > and change Network Mode to GSM only.

This.
4G and 3G use the same "part" of the network.
T-Mobile's network is not like Verizon or Sprint, where a completely different communication channel is being used.
The functionality is quite similar to WiFi...With 802.11 B and G, they use they same frequencies and talk on the same channels. However, 802.11 B tops out at 10Mbps, while G is capable of hitting (theoretically) 54mbps. The only caveat being that both the access point and the client, must support the updated protocol.
So yes, although it's doesn't seem logical, your choice is either 4G (HSDPA and HSDPA+) or 2G (EDGE).
If 3 and 4g are the same on Tmobile's network, then when you're on 4G, does it use any more battery than it does on 3G?
My user experience says yes. The battery hogging is on par with the EVO and Sprint's wimax. There was a switch to revert to 3G, and all sprint users that I knew never used 4G because it drained the battery in a matter of a few hours.
On an AT&T iPhone 3G, the battery never drained this quickly.
Please keep all question based threads in the Q&A section.

As long as i am not leaving the 3G or 4G area, i set mine on wcdma only. Problem solved. When i travel into 2g areas, i put it back on auto.

Someone correct me if I'm wrong.. But our 3g and 4g has no dependence on our radio. It's dependent on the signal we receive. So to answer your question, no power is saved because 3g and 4g use the same part of the phone. Only on 2g because a lower power radio is receiving the data signal
Over 10000!!! You bet I am.

Does anyone think or know why or why not we can flash the radio from the G2 to work on the vibrant to get the HSPA+ network connections. or is this a hardware thing? im not a dev but wouldnt mind learing so i can contribute too.
it is a hardware thing. the vibrant can get hspa connections but not hspa+. hspa maxes out at 7.2Mbits/s though, so that's still pretty good.
How would we be able to get hspa working? I think my touch pro2 was on hspa. I always had the H logo in the tool bar.
Sent from my SGH-T959 using XDA App
This same question has passed my mind as well. More often then not I notice in the phone status that the signal is UTMS, on the rare occasion is may say hsdpa. So i wouldn't be surprised if in the radio settings, utms is the preferred signal type.
we already have hspa. hspa+ is what the g2 has. hspa is just 3g...
From past experience with all of my previous smart phones the radio firmware upgrade is hardware specific.....So a Samsung radio will not work with HTC(G2) firmware.
for t-mobile, when you're on HSPA or UMTS, it just uses the 3G logo on the notification bar.
you can check at settings->about phone -> status to see what mobile network type you are on. mine says HSDPA right now, but when i'm at home, it usually says HSPA.
when they update your cell site with the HSPA+ cell, you will probably get an increase in speed because they will probably upgrade the internet connection to the cell to support HSPA+ speeds which means you get up to 7.2Mb/s. I think someone said earlier that most 3G sites only have two T1 lines as the backhaul, meaning you will probably get max 1.5Mb/s in a speed test.
Hardware thing. MIP
HSPA 7.2 is good enough for me and when HSPA+ rolls out in my area I ought to get closer to that theoretical speed more often. I've seen speeds like 5.9 Mbps on Speedtest.net when I'm near a regular HSPA tower.
I do wish we could mod the icon to display an "H" on HSPA connections like the G2 (G2 shows an "H" for regular HSPA as well as HSPA+). I remember running Klick Hero on my G1 almost a year ago, and getting the H icon from time to time on that old thing!
You can confirm you are on HSPA with the Mobile Signal Widget.
Itll show h on 2.2

The reason you cannot flash the G2 radio to get HSPA+ on the Vibrant is because the Vibrant DOES NOT HAVE A HSPA+ RADIO. Flashing the radio/modem software onto the Vibrant will not help and will probably damage your handset.
Adding software to the phone to use hardware it does not physically have is pointless.

You don't do anything to "get HSPA working", because it already works. If the cell site your handset is connected to is HSPA, then that is what your handset will connect with.
Just because the icon in the notification bar says "3G", this does not mean that you are not connected to a HS(D)PA network. Check "Settings > About phone > Status > Mobile network type" to check which type of network you are connected to. Mine currently says "HSDPA", but I have a "3G" icon in the notification bar.
Does anybody think its possible to take a baseband chip from the Epic 4g, and solder it into the Vibrant to get it to work with Sprint's WiMax network?
Only way I see that happening is of you mod the phones hardware then mod the software drivers to make it work...it can be done but is a huge pain in the butt....I use to mod our sat phones and radios over in iraq to bump signal for direct calls...the hardware side is easy little patch work needed....software side to make it work is where the work would really come in...mod for the kern...then drivers...then fixing all dependency issues for the radio...then last part is the battery issue...you would have to find a radio that wouldn't eat like it was at an all you can eat dollar dinner....but if you are into hardcore mods keep everyone posted...lol

Not without a ton of programing knowledge.
i would venture to guess no, because more than the baseband chip would probably need to be included. you'd probably some of the receivers as well. At the very least, the chip marked wimax power amplifier.. http://www.chipworks.com/samsung-epic-4g.aspx
why would you want to do that anyways? the phone isn't designed to support two baseband chips so you probably wouldn't have any way of having both tmo and wimax. might as well just buy both phones

The shipped ROM on the Vibrant does not display an "H" for HS(D)PA connections ever. It will only show "G" for GPRS, "E" for EDGE and "3G" for UMTS, HSDPA and HSPA.
Try phono which shows real time signal. I was able to find the right spot for signal at work.

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
Tarzanman said:

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
Thanks

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.
This may be a lame question, but if 4G becomes active in my area, is there anything i need to do? or will the 4G notification just turn on when a signal is detected?

Its not lame, its how you learn. In theory, no.
There are settings for CDMA and LTE under the mobile networks area so assuming you are set to CDMA / LTE, running stock and you are close enough to a LTE tower you should switch to LTE automatically. If you search there are a number of tweaks and additional settings also available in case you aren't successful.
If you never change your mobile network mode from cdma/lte in your settings then it should automatically connect if you ever get lte in your city.
The above posters answered the question, but if you would like to know more about when LTE might be available in your area head on over to www.s4gru.com

so i don't really know alot about the CDMA/LTE stuff... but on the original Evo the 4G was on the CDMA network correct? The New EVO just has 4G on the LTE network? Meaning if i was able to pick up 4G in my area with the original EVO i won't be able to get 4G with my new EVO LTE until they add LTE in the area?
am I understanding this correct?
Correct, 4g was on the wimax network, now 4g is lte. Wimax is still available, it will eventually be phased out.
That sucks... I live in bumf so doubt I'll have LTE anytime soon... But at least this phone is still awesome

Hello, I recently switched over to Tmo from Big Red. I have mixed feelings about the switch. Overall I'm satisfied, however the signal strength near my house sucks!!! When I have LTE, it's great!!! My major/question is how is it 2013 and have no 3G? I go from 4G/LTE to 2G in about a mile. Does Tmo not support 3G?

Use the app Open Signal from here It will show you when your using 3G because even if when you are on 3G it shows 4G icon on tmobile because the 4G is the upgraded 3G
When you run the speed test it will tell you if you are on 2G, 3G, 3G/HSDPA (which is 4G), HSPA+ or might show as HSPAP which is the 42Mbits, and then 4G LTE

also you can put up a widget on your screen from Network Signal Info. I use it all the time. Great little widget that will show you your current connection type, signal and a whole lot more info.
What i use it for is to watch my UMTS connection and see if i am on HSDPA or + aka 15 or 21, then it also shows LTE when your connected to that..
If your in a spot where your not sure what connection you have this widget works wonders.
Would you use a 3G only option if it was available on the G3?
I spoke to a Verizon Regional Exec today about the G3 and other Verizon phones that no longer have the option to run on CDMA only. The rep has an iPhone and regularly sets it to 3G only, especially when he let's his kids use the phone. He could not give me a reason why the G3 and other phones no longer has the ability to go to 3G only. He said he would look into this and see if it could be delivered in a future update.
Honestly I rather not have data at all then be stuck on 3G, just my opinion
I would like that option. There are areas where I play Ingress, for example, where the 3g Verizon signal is strong and uncluttered so its a much better option than LTE, which is either weak and eats battery trying over and over to reconnect, or is good but WAY oversold so there is no way to get good speeds on my unlimited data plan, much of the time.
One of the tricks we used to use on the VGNexus phones was select 3g only and save much battery life. 3g can sometimes be faster than 4g and it saves power by not running the rg radio.
Sent from my VS985 4G using Tapatalk
I can do this using com.lge.hiddenmenu. it has an intent that if launched will allow you to pick your desired frequency/bandmode. it includes lte only, cdma only, evdo only, cdma/evdo, and lte/cdmA/evdo as well as global.
i often have poor band 13 lte coverage and so it saves a lot of battery. sometimes it is nice to block 1x to improve speeds and force 3g if the signal is producing more speed then 1x. just my 2 cents,,,and if you get creative you can create a shell script to "su" then run the intent and then exit. place a shortcut on the homescreen and profit.
im reflashing my softbrick now or i would put the exact intent needed, maybe tomorrow if i remember but its network selection, network mode, something like that and way towards the bottom (last third) of the intents i viewed within hiddenmenu,apk
Please conform that the coma,option is available on works on the vs985

The GNex was one of the last phones to be affected by that. Since Qualcomm took over Android, their integrated LTE radios use no more power than 3G radios.

Basically. I think a full 3G signal is a little faster a very weak LTE signal, but at this point anywhere there's full 3G there's LTE.
Just download a massive amount of data and the carriers will throttle you down to 3G or lower, with occasional 4G use. As for some people saying that 3G is never faster, it depends on the carrier. Verizon throttles all 3G usage in an effort to convince 3G users to upgrade to 4G.
