So, LTE signal in my area has been from 1-2 bars to nothing(though, I'm not sure quite why, RSRP(dBm) shows -96, RSRQ(dB): -7, but I don't know what that second one means.), and for some reason instead of going to HSPA+ when I dont have enough bars, the device goes to "H", which I believe is just HSPA, and speedtest.net app confirms this (2-3Mb/s down). Is there a way to get myself onto HSPA+?
I'm on an int ROM atm, but from what I can see the issue carries over to my stock rom.
Also, is there a chance that flashing the radios from the int forums would improve things (are there newer radios that might help with the LTE signal issue, rather)., or is that a no no?
edit: huh, actually the 2-3 down I'm getting shows as HSPAP (which I assume means HSPA+), so I guess that means I am on it and ATT's HSPA+ network just sucks where I live.

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.

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.

What 3G speeds do you get with your Vibrant running on At&t's network?
I tend to see about 1.0-1.5mbit down and the same speeds up when i have 3-4/5 bars.
Also when you go indoors do you see a dramatic decrease in signal? I sure do and it annoys the heck out of me. But the weird thing is most of the time I still pull in at just under 1.0mbit down and same up.
Signal depends where you are at, In Hawaii I got decent ATT (TMO edge only) most places,
Here in SFO area I get Great connection with ATT indoors or out (I tested to see how it works here)
So, in Hawaii, 1-up 1-down on Att Here in Ca 3up 1.5 down
In Chicago area with strong signal I get up to 5.9 up and 1.3 down.
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.

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.

I attempted to do my homework on device compatibility beforehand so as to avoid the shock of something like being stuck on EDGE for data. Nevertheless even with a video review showing the DNA operating HSPA+ on Solavei I am stuck on dreaded EDGE. The activation period took a couple of hours with my new phone (DNA) being able to dial out but SMS/MMS non functional as well as calls to my handset. EDGE was running during this time but after a bit I saw it flash to 3G then H.....success! NOPE. At this point I verified SMS and all calls were working and my phone seemed to want to connect to HSPA+ but was having network communication issues when trying to run speed tests. I attributed all this to my home location, it having always with any carrier been quite on the outskirts of general coverage even though I'm only 1/4 mile from town which is a bit ludicrous in itself. Later that night I drove a little into town to test the data and alas H+ lit up, ran a speed test 2.5MB download...not to shabby IMO. Next day I drive to work and into the center of my home area where the best coverage is for ANY carrier and the entire trip H+ only lit up for a few seconds. Ever since there is no change in data always on E. I called Solavei and told them the issue and they pretty much gave me the runaround and couldn't definitively explain why it worked for a short period but wouldn't now. I can't 100% confirm that T-Mobile has refarmed the area to 1900Mhz but I read my city in a list of 49 in an article that said they were done. This being said I'm forced to let this month play out until possibly switching carrier perhaps one that uses AT&T instead. I asked Straight Talk about my device and they said they offer SIMs for both AT&T and T-Mobile but AT&T is limited to 3G service only whilst T-Mobile should work for HSPA+. I don't know if this a T-Mobile issue or a Solavei one or it's just my phone, but don't see how it could be the phone since it was up and running briefly.
I use T-Mobile and my connection is all over the place at times, refarming is actually the reason I think, its going for the strongest signal, if its edge, it gets edge towers, until the refarm is done I think we'll continue to see this kind of behavior for awhile. As time has gone by its gotten better around here with less time on edge and more on 3g/h+ since I first got the phone.
I can't vouch for at&t but no h+ sounds a little strange to me, if anything bands wise they should be more compatible then T-Mobile.

It sounds like the refarm is much more of a gradual process than a one and done. At least I hope so or else there's not much to look forward to there. I know the Solavei rep was full of complete and utter BS since she told my phone was incompatible since it wasn't on their database of phones to service APN settings OTA. I may try out Straight Talk or Net10 just to see how the AT&T network speed performs.
Sorry for my ignorance, does the DNA really get H+ (42Mbs) ? On GSM network?
Thanks

No reason it can't, hardware supports it if you have the connection to do it. In my coverage I'm usually edge or 3g so I can't say for sure.

I ended up leaving solavei (T-Mobile) for net10 (at&t) The coverage is worlds apart in terms of hspa. I get it everywhere though the speeds fluctuate but are decent. T-Mobile definitely needs to expand coverage it was not good where I lived about 80% was edge.
Does anyone else notice that the LTE signal on this phone always seems on the weak end? For example, with the T-Mobile cell site about 10 yards away, my LTE reception is -90-95dbm. When sitting that close with my AT&T iPhone 5 (work phone) the signal is about -75-80dbm. What gives? I also notice that the phone does hold onto weak LTE signals, but I am seeing weak LTE signal more often than not. I have seen a -115dbm-120dbm LTE signal. Yes, data still works, my only concern though is that the battery life is getting sucked out of my phone?
Running stock, T-Mobile also likes to show 5 bars for a -109dbm LTE signal. That couldn't be more of an exaggeration could it? Also in my tests, I have noticed if you set the phone to WCDMA only, the signal is a lot stronger.
Anyone care to comment on this?
No issues for me. Even in the factory that i work at i am getting 4G LTE over people with ATT and its quite strong. LTE Tower is a good distance away.
Have you rooted or flashed anything? If its 100 percent pure stock, ask for a replacement. Or even re-flash the latest update to see if that helps.
The only issue i have and others have is where the outgoing data arrow constantly lights up but no data is coming in. I think its a T-Mobile programming bug in 4.4.2 as the issue didn't exist in 4.3 on my S4.

Yes, but on average what is your dbm? Not going by bars.
T-Mobile also does not have a dense cell grid in my area which could be why. Already past the 14 day return window. Absolutely no device modification has even done.
I'm at full 5 bars on LTE 4G signal strength @ - 97 dBm

Appreciate the response. Been doing some research lately, and I think its because t-mobile doesn't have many sites in my area. I don't think their frequencies travel far either. Maybe I am wrong, but wouldn't this cause very low LTE signal?

If the towers are far from you, I would think that would cause a weak signal.
You can try this app.
It may help to see where the issue may be regarding towers, etc

It does give you a more accurate signal bar strength indicator consisting of 14 bars and not 5 bars, as the stock indicator does. I'm at 11 bars.

Ahh. I will have to check the dbm. I don't get full signal but i get like 2 bars. Sometimes four depending where i sit. Then outside, i get full bars. I'll double check the dbm outside with full bars. It should be in and around the -90s.
