Biggest Rhodium Disappointment? Phone reception.

Since I have gotten my Tilt 2 (ATT), I have not ever gotten good reception. I've flashed every ATT Radio, the newest radios (even non-att) and am running EnergyROM latest and can never maintain good phone reception. I always drop calls.
I know it's not my area, as I got great reception with my previous phone!
I feel like there is no way to get phone reception!!
Very disappointed in that
You guys experience the same problems?

no but theres no dead zones at all in houston.

yeah, i have nothing but good reception in my area (austin, texas and surrounding areas). Maybe you have a faulty antenna on your device. Have you called in At&t and tried to get a replacement? Head down to a Device Support center and talk to the guys there and they might change it on the spot for you, which i've had done many times with my original tilt and fuze.
Good luck.

Well, I changed my GSM Band to 1900+850 and flashed the latest radio and I seem to get better coverage.
One problem though (though it is minor): with these settings, it doesn't use HSDPA, only EDGE, which is slow lol
Any suggestions... please? Haha like maybe ghetto-rigging it with tinfoil? Ha I'm desperate

have you checked the coverage map of AT&T in your area? and also the material your house is built can also play a major role in signal, do you get more signal outside?

Calling all At&t users with a custom 4.0.3 rom installed.

I know Google recommends xxkk6 or UGkk6 with 4.0.3 however I get abysmal battery life with xxkk6 and I get frequent cell service drops with the stock xxkk1 radio.
What radio are you guys using?

xx seems to work better with AWS/1700 bands. Try the UGKK7 and UGKL1 basebands. Those were designed for canadian carriers which should use the same bands as AT&T.

T-Mobile user here, but considering the phone isn't out here we're pretty much all in the same boat. I've tried XXKK1/6 and UGKL1/KK7, and UGKL1 was by far the best reception for me. My buddy on AT&T said the same. UG designated radios are North American.

My phone came with XXKK1, and when I unlocked the bootloader and switched to a 4.03 ROM, I switched to UGKL1. While I'm getting less "bars" than I used to with my Motorola Milestone, my actual signal strength is about the same (-60dbm in great areas, -90 in my house). I feel like UGKL1 is slightly better, but its tough to say.

[Q] Best radio to use with Galaxy Nexus on T-Mobile USA

So the official GSM version of the Galaxy Nexus (http://code.google.com/android/nexus/images.html)
is supposed to have xxkk6 radio (radio-maguro-i9250xxkk6.img)
I read in another place that the Asian varian has a different radio, and the canadian varians also have different radios. So being that the GSM Galaxy Nexus is not officially in the US on ATT or T-Mobile I was wondering wich radio is best to use on the T-Mobile network?

North American code is UG, I think UGKL01 is the newest released radio.

I am using ugkk7. Look in dev section to see if there are any updates.
Sent from my Nexus in Texas.

I'm using XXKK6 - it's been working fairly well for me. Probably gonna try out one of the UG roms.

i'm currently on UGKL1, live in denver colorado (where t-mobile has 4G coverage) and i dont get any type of HSPA+ speeds, on a good day my down is only 5891kbps and my up is a mere 1243kbps (same speeds as my Nexus S).
maybe US radios are optimized for CDMA networks, i'll switch to XXKK1 later and see if it helps - anyone actually get 4G speeds yet? if so, which radio are you on?

Probably best to use a UG based radio if you're in NA. I'm on UGKL1 and it's fine. I accidentally flashed an XX radio before and data would cut out a lot...

i updated to stock 4.0.2 for tmo and i'm getting 10mps down and 2 up around my area of the woods.
kk6 radio band.

I got 8.99Mbs down and 3.69Mbs up, in the Tech Center this morning. I usually get around 3-5Mbs down Downtown. I'm on the stock 4.0.2 XXKK6 radio.

I get about the same down in Parker with the same stock radio on 4.0.2. I have not tried any other radios yet, but my wife's HTC Amaze is twice as fast as expected.

If your tower doesn't have any more capacity available, it doesnt matter what *you* do. There's only 21mbps (or 42, depending on where you live) per tower sector to go around to every user in your sector. If it's 21mbps, all you need is 3 other active people on your tower to get those speeds (factor in radio link loss too).
Long story short, not a single thing you can do to control your speeds. And judging a radio's "ability" based upon speed test results is extremely inaccurate.

And the nexus only reaches 21mbps on T-Mobile anyways so there's that. The north American radios are optimized for Canada.

So my area JUST got 4G on a partnered carrier that TMOUS shares. Im getting 4g on my Sensation but am thinking about getting the GSM Galaxy Nexus. We went from Edge to 4G. All i want to know is if i will be able to get 4g on the Galaxy Nexus for TMOUS?

If you get it on the Sensation theres no reason why you wouldn't get it on the Nexus.

I was using the KK6 radio that came with my phone (assuming it was a UK one since it had a UK style plug in the box) but within 2 days of getting the phone I had dropped signal errors where only a reboot would fix it. I moved to UGKK7 and haven't had any issues since. Pretty sure my speed is slower though (haven't testing yet) so if you have no issues with KK6 keep it.

i've been on KK6 for about two weeks now, speeds never go above 5.5down - i guess i dont have very good HSPA+ coverage north of denver. i also have to turn on and off airplane mode once a day to fix connection issues.

I'm using XXKL1. I get speeds near 5-7 Mbps. Sometimes 9-10 if I get lucky.

I'm also in Chicago on the xxkk6 radio and I never seem to be able to get above 3-5mb down and .5-1mb up. I've also noticed that it shows "3g" as the connection status most of the time, save for when it momentarily shows an H at times.
Anyone have a clear answer on what is displayed when you attain an HSPA+ connection w/ this phone? I find it weird that with the dense 4G coverage in Chicago, I can't seem to get any better speeds than what I get w/ my N1.
Cheers, dudes.

Those sound like pretty standard 4g speeds to me. On a good day I get 10mbs. It really depends on how many people are sharing your tower. People with Verizon LTE are reaping the benefits of new technology without many users.
As for the icon I believe the GSM radio switches to 3g when no data is being transferred and switches to H when active to save power.

[Q] Gnexus Signal/Wifi Quality?

I purchased a Galaxy Nexus from Verizon shortly after release and I ended up returning it due to connection issues. The signal was very weak in areas where I normally have a good signal strength. This was causing some missed calls. Also, I had troubles staying connected to my wifi from the bedroom when every other wireless device I own had no such issue.
I am not overly impressed with SGS3 and I find the $399 no contract Galaxy Nexus to be very attractive. I am considering giving the GNexus another try but I don't want to go through the hassle if I am going to have the same issues.
Finally, my question is, will I have a better connection with the non-Verizon version of the phone purchased directly from Google either due to it being a different version or due to updates since I last tried it with Verizon shortly after release?
I enjoyed the phone other than the issues I mentioned above. I am currently back with AT&T and off contract since I returned the Verizon phone. Thanks in advance for your opinions.

Well I didn't get a response here, but I ordered mine from google yesterday. Hoping for the best and will post what differences I see in case anyone is interested.

Honestly don't think the WiFi will be drastically better. They're pretty much the same, although I've never particularly had issues on my GSM model.
Hope it works out.

The GSM doesn't have cell signal issues like the Verizon one. But wifi will be the same. I've found the wifi range to match my atrix for distance from router. I ignore the bars and just read the signal dBm and its fine.

I've had my GNex for a little over a week now. At home and at work, I get great signal for GSM/3G, and Wifi is excellent, as long as it's 2.4GHz. 5GHz works, but is weaker due to higher frequencies not penetrating walls as well.
Out and about, it's a different story. MANY business that I go to will have ZERO signal indoors, and I will have to go outside to do something as simple as a Yelp check-in. GPS also falters pretty seriously. I upgraded to 4.0.4 as soon as I could. My phone is rooted, but has the stock ROM. My Captivate got a MUCH better signal than the GNex, and was about to ask if anyone knew a way to boost the signal. My battery life is phenomenal, but I would gladly sacrifice some of it to be able to get a usable signal inside a building made of something other than wood.
UPDATE: After I did a bit of research, I determined that the GNex that shipped from Google had the XXLA2 radio on it, which is odd since it's a phone that's only sold in the US. I did a bit of research and changed the radio to UGLC1. If I'm right, the European baseband won't do anything on 850MHz, but the NA Baseband will. I'll test it out and report back here. If I'm right, then shame on Google for shipping a phone with the wrong radio!

OK then it definitely doesn't seem as wide spread as the cdma one. Solid signal for me personally.

What would you consider adequate dBm?

OK, I've had my GNex for a little while now and I can definitely say that I'm happier with GSM version. I have none of the signal issues that I had with the Verizon version. Thanks to all that replied!

What Radio Are You Using? (Australians)

So I wanna know what radio your using. And what carrier, I'm on optus and I don't know whats best. Im currently on KK6 as it gets the best speeds...

I'm on TPG (Optus reseller) using stock radio...the speeds for me **** all over what i was getting on my Sensation last week

UGLC1
I am with Vodafone, and recently (3 days ago) flashed UGLC1...works very well for voice calls, I'm getting roughly the same speeds on my phone as I do on my broadband at home (tonight 3424kbps down, only 422kbps up; on 6/5 I had 3934kbps down, 1757kbps up), and my wireless strength seems to be better than it was on stock too.
I had major call quality issues with KK6, and trouble getting a signal at all with KRLB1 (though I was fiddling around with radio bands at the time and got stuck on AUS rather than AUTO, so that may have interfered with my results).
Basically, the best way to do this is to back up your radio (use the Galaxy Nexus Toolkit), and then download some off xda and see if they work. I'm sure you know that Speedtest.net has a great app to use for benchmarking.

I'm using the XXLA2 radio with the Swedish carrier Telia and it's so-so.
What's the difference between having "WCDMA Preferred" and "GSM/CDMA auto (prl)" as was pre-4.0.4?

There's some detail on this thread:

they are carrier dependencies and refer to how a carrier handles voice calls...GSM is the standard most used, WCDMA (i think) was the early 3G

I'm using XXLA2 with Optus. It's better than the original KK6 for me in terms of reception I think. I haven't really tried changing the radios just because I don't really have any reliable way of benchmarking them lol. Keen to get an answer here

XXKK6 here on TPG (optus)
never had any problems with it so haven't touched it, though I never download any large files on mobile data so can't really say anything about speed (I tend to stay under the 50mb/month 'free' PAYG data lol)

I just tried the SC04DOMLE3 radio, with not very good results...a couple of calls were fine, but one was garbled and one dropped out unexpectedly.
I've reveted to UGLC1, which has been pretty stable for me over the last two or three weeks since I flashed it
