[Samsung Galaxy Nexus] kangxi:
You aren't really troubleshooting, just speaking regarding something that really can't be fixed with a software patch.

And no, my apartment has very thick walls. T-Mobile wasn't able to get any service at all in there. When I had the RAZR, I got service in there. Low service, no 4G. My Nexus continues to get the same.

At work, my cafeteria is the same as the apartment. No service. RAZR got service in there, even the elevator. Nexus does the same. What I'm saying is that the same places I got service with the RAZR, which many people hail to have excellent service, are one and the same with the Nexus.

The people with problems of course are going to be most vocal. I'm simply saying that more than likely, something is wrong with your devices that you should bring up to Verizon. After all, you all paid a lot of money for these devices. All these threads and people are leading everyone to believe this phone is a piece of crap and they all have crappy radios which isn't the case. If 4 out if 10 people say their reception is great, then wouldn't you think the other 6 could have defective devices, especially if they didn't have problems before?
[Samsung Galaxy Nexus] jumpinj:
I'm in the exact same boat as kangxi. I'm in Orlando, as well, and had a RAZR for a bit. It would get a 4G signal (albeit a weak one) in places that my Nexus won't even consider. Now, I can't even get 3G data.

All this with the new radios flashed back on the 21st. The new radios did seem to work for a day or so, with seemingly better "signal stability" and hand off from 4G to 3G. Then, I drove south to visit family, and now, upon my return, I can get 4G in certain parts of town, but no 3G at all. At home, I get WiFi data only, even though Sensorly shows -80 to -100db signal on CDMA...but no 3G.

I'm beginning to think my device is just defective.
[Samsung Galaxy Nexus] sc4fpse:
Radios didn't seem to help me get 4G back in areas where my Nexus can only pick up 3G, but my Thunderbolt pulled 4G no problem. However, battery life is a million times better. No longer do I have the "10 minutes off-charger, 10% lost" at my parents' house, which is an incredibly low signal strength 3G area.
[Samsung Galaxy Nexus] TEK112:
We have been troubleshooting, not just here, but at rootzwiki and droidforums. Trying different radios and posting results. Mixing radio parts and trying different ROMs and kernels to rule out app/system interference. There has been an investigation to see if antenna placement could be an issue. There is a youtube video about that. A software fix can definitely improved radio stability. That's what firmware updates do. It may or may not work in this case, but I am willing to try.

It has already been seen that the newer radios have improved handshaking globally and in some instances has improved reception. I personally have signal connect has improved dramatically with the 4.0.3 radio, however, the reception is still erratic. As I said before, I am willing to accept that it could be a defective unit. However, I am going to hold out to exchange if an update is released before then.
[Samsung Galaxy Nexus] stopswitch:
San Diego, CA here. Flashed these radio leaks three days ago and I must say they are way better. I do not get better signal strength, it hasn't changed at all. But I do not lose LTE anymore in the city area of San Diego. The hand off from CDMA to LTE and vice versa is way faster. The biggest pro for me was battery life. I am 6 hours into the day with LTE always on with moderate use and my battery is at 75% this is with auto brightness, no wifi, nfc on, LTE always on, GPS off.

Thanks for the leak guys.
[Samsung Galaxy Nexus] Skilover:
Under phone in settings it still says 4.0.2 after what appeared to be a successful flash. Anyone else? Tried twice. No error.
[Samsung Galaxy Nexus] kangxi:
The Android version isn't going to change, the baseband is.
[Samsung Galaxy Nexus] techbeck:
made no difference to me at all with the new radio.
[Samsung Galaxy Nexus] michaelkahl:
Real unscientific but I still found it interesting. I'm on factory radio/stock 4.0.2.

I'm at my Moms for Christmas, no 4g. I'm on 3g like my sister and both phones report -75 db and mine pulled 2mbps on a speed test which is inline with past experiences out here.

I still have issues getting 4g in areas where my TBolt did but I'm not terribly worried at this point.
[Samsung Galaxy Nexus] dynamicpda:
I don't have a Tbolt for the sake of comparison.

I'm coming from Sprint with the Evo. In my house, I just pulled 7/1 mpbs on the Evo via WiMax. With the Galaxy Nexus out of the box, I could hardly get a connection with frequent swaps between 3G and 4G. The 4.0.3 radio is a lot more decisive, definitely no 3G or 4G data in the house.

On the street, 4G seems to be fine. Will have to try it out more in restaurants and clubs. It's really sad that with such a great phone that something as basic as the radio has to take a step backward.

I have WiFi at home so this situation is OK but sometime I will be in a situation where I don't have WiFi and a proper radio will mean the difference between data or no data and I will be pissed at Samsung.
[Samsung Galaxy Nexus] Flip35:
hey guys quick question, i notices we have the leaked radios for 4.0.2 n 4.0.3 now i havent had issues at all with my signal on 4g or 3g should i still flash them, would that give me an advantage or since i have no issues that i can tell is best to not even mess with them, im running right now the rom ZYgot 1.8 but i really havent been out since ive been running this rom and i use my wifi here but i dont know what to do, im scare to flash them and then i start having problems but im also thinking if they are supposed to be coming that means we need them, trying to get some ideas on what to do, thanx
[Samsung Galaxy Nexus] dynamicpda:
Best to do nothing if you are worried about giving up a good situation. If you were on stock, you would have upgraded to the 4.0.2 radio and eventually to the 4.0.3 anyway.

I haven't had a problem flashing the radios on any device. You could always flash back if you didn't like what you see.
[Samsung Galaxy Nexus] Flip35:
i guess ur right, theyre there for a reason so that means we eventually are getting them so if not i guess i can go back so ama give it a shot, thanx
[Samsung Galaxy Nexus] pattont:
I loaded the radio tonight since I am out of town at relatives and they are on the fringes of getting 4G and my phone was having issues going back and forth between 3-4G. After loading it the change over seems instantaneous. Also, the wifi handoff back to a cell network seems better.

Cool!
[Samsung Galaxy Nexus] FruitBowlMafia:
No signal strength increase, VZW should be ashamed. I have a RAZR as well, put the SIM card in and it picks up a full signal. Put the SIM card in the Nexus and I get about 20% signal. Also the hotspot on the RAZR is running around 1.6MB down and on the Nexus I get 500KB down (just 3G at my house) VZW told me is was a false reading on the device and I was really getting full signal. It's an outright lie Big Red
[Samsung Galaxy Nexus] Stadsport:
I flashed this a few minutes ago, running ARHD 2.1.2. In the same spot, it went from -100db (1 bar) to -93db (two bars). So I'm pretty happy there, but I'm mostly interested in battery life gains!
[Samsung Galaxy Nexus] kangxi:
The bars on the RAZR do give a false reading so the rep was correct. You shouldn't look at the bars, look at the dBm.
[Samsung Galaxy Nexus] shoman24v:
I'd rather see dbm over bars any day.
[Samsung Galaxy Nexus] weedahoe:
Stock 4.02 works fine for me but then again, im not in a 4G area. I flashed to 4.03 and noticed two issues.

Wifi Tether will not work with 4.03. I consistantly get errors in the startup log. Even worse, when on wifi at home im fine and my signal icons are blue meaning im connected to google servers. But if i disconnect off wifi and use my cellular 3G connection my signal icons stay grey and will not turn blue.

I had to flash back to 4.02 and instantly got blue icons on 3G and now my Wifi Tether works.
[Samsung Galaxy Nexus] locust43:
*22899 is meaningless on LTE/CDMA phone's. The IMS Map Core on the LTE network via. eHRPD takes care of updating the PRL.

But the old saying updating the PRL will fix network issues is bogus anyways, except for people in Alltel area's during the integration or when they roam.

Native Verizon tower's don't change and even when new tower's are added a PRL update isn't needed. Also the LTE network doesn't use a PRL, it uses an HLR method.

PRL update's are automatically pushed when you power cycle the handset.
[Samsung Galaxy Nexus] oz1421:
Hey all - thought i would chime in with my experience (did a search didn't see anybody mention this happen) - i flashed the zip file phone restarted - and my Baseband was "Unknown" so i had no signal ... that was an o sh!# moment to say the least - anyway just went back flashed it again and that seemed to have done the trick

in case anybody runs into that.
[Samsung Galaxy Nexus] maybeiknowstuff:
I got 4G long enough to do a speedtest, then it went away. Of course this isn't final release so I hope Verizon and company can figure out rest of the kinks. I'm in the boonies for Christmas so it was worth a shot. No noticeable change in dBm (93 to 93) That's clearly is something we can't trust in terms of CDMA. Should be more to come in the future.
[Samsung Galaxy Nexus] driniM3:
First post on this site. Hi to all. Just flashed the antennas. No noticable difference in signal strengh or speed tests. It does however seem to switch from wifi to 4g alot quicker. Instantaneously in fact. I will be able to really test this out more during the week because I do alot of driving and my phone is always switching between 4g and 3g while driving which is annoying because i am usually streaming music and 3g seems waaaaaaay too slow after using 4g as Im sure everyone has experienced. Anyways we will see if it is able to keep a more stable connection to 4g and I will post my results.

As far as battery life goes I cant really comment because my phone is plugged in my charger at work, car, and home so i haven't really been off of it much.
[Samsung Galaxy Nexus] FruitBowlMafia:
What about the bandwidth then?
[Samsung Galaxy Nexus] stopswitch:
Flashed this four days ago, bandwidth is amazingly faster. When I first got the phone my downloads were at about ten mbps and now its climbed into the 30s most of the time. Pretty impressive for a firmware patch.
[Samsung Galaxy Nexus] pattont:
I have the 4.0.3 radios and the beta 9 version of the wifi tether and mine works fine.
[Samsung Galaxy Nexus] vismal:
Am at my girlfriend's parents house in the boonies. Old radios gave me 3g with good signal. New radios flashed and now I'm 4G with 1 bar!
[Samsung Galaxy Nexus] FruitBowlMafia:
:mad:well you must be under a tower with a charmed Nexus because the radio on this thing is a POS:mad:
[Samsung Galaxy Nexus] triphumphrey:
So I just wanted to check in with everybody to let you know how my data gathering is going. I have about 40 observations so far...but I had to travel for the holidays and I didn't want to mess up my data adding a different location as a variable.

I will resume my data collection when I get back home and then proceed with flashing the radio.
[Samsung Galaxy Nexus] player911:
Anyone not seeing 5ghz WiFi networks after this? My neighbor has a dual band router with normal 2.4ghz and a 5ghz network. Now I can't see it.

My neighbor and I are IT guys and holidays always spell trouble because people get new routers and don't program them properly. Occasionally ALL networks will start going crazy and I've been trying to figure what is causing it (cordless/baby monitor/etc). Well I remember seeing his 5ghz on my nexus the other day (pretty sure) but a few days ago it disappeared. I've reset a few times and even double checked with him. My Roku box also see's it. But not my nexus now.

It could be anything (CM9 Kang or new Radio). Just curious. I read a thread here about 5ghz disappearing and others have been using theirs just fine. It didn't say if he was on a custom build or not. I can't find the thread anymore but I figured here would be a good place to discuss this (better then another thread).

[Edit]

Just tested and seeing it now. Maybe it was his router being stupid. He has dual band enabled but doesn't use the 5ghz frequency.

So anyone still seeing 5ghz networks with the new radio?
[Samsung Galaxy Nexus] kjwalker:
I can't even see my 5ghz network WITHOUT flashing the radios. Running Revolution HD 2.1.2 :(
[Samsung Galaxy Nexus] pakxelaos:
Yeah...still can see it

No problem here
[Samsung Galaxy Nexus] donlad:
I am able to see 2.4 and 5 GHz signals in both the 4.0.2 and 4.0.3 radios
[Samsung Galaxy Nexus] oc3rulz:
Yeah I can still see and use 5Ghz WiFi no problem at all. Must be the kernel in the rom that you are using causing your issues
[Samsung Galaxy Nexus] profundus-sanus:
well, i was hoping for a larger improvement from this.

at my parents house for christmas i see -120(lucky to even make a call), my brothers x2 -90, moms droid 3 -90.

can hardware really make THAT much of a difference? i'm really contimplating returning the phone, i love everything else about it so i'm trying to make sure i've given it every chance.
[Samsung Galaxy Nexus] kekspernikai:
I haven't had signal issues myself. It has been noted that Galaxy Nexus and 4.0 are the first LTE phones that actually show accurate numbers and signal bars for LTE, rather than the CDMA numbers. Were all the phones on CDMA only?
[Samsung Galaxy Nexus] letus:
I don't mean to be flip, but you are kidding right? Hardware makes all the difference in the world. Antenna design, componenent interference , trace length, pcb quality.... the list of hardware defects that could/can ruin a radio is pretty damn long. In fact for a radio to work well, nearly every part of the system needs to be higly optimized. No amount of software can rectify bad hardware.
[Samsung Galaxy Nexus] profundus-sanus:
i mis-spoke, i appologize. i meant to say software instead of hardware.

yes. all were on cdma only
[Samsung Galaxy Nexus] sorb3t:
Connection seems to be a lot more stable, no random data drops. I definitely, think the new radio is better. Battery life OK, maybe a little better. Thanks for the update!
[Samsung Galaxy Nexus] kangxi:
Your device is probably defective unfortunately. There shouldn't be that big of a gap between devices.
[Samsung Galaxy Nexus] FruitBowlMafia:
Yes, still running on 5Ghz here too.

Sorry bro not sure what the issue is, you could revert back to stock and start all over:(
[Samsung Galaxy Nexus] champers:
Updated to 4.0.3 radios and my signal dropped from -93dBm 2 asu to -120 dBm 99 asu. Slight drop in download speed, equal upload speeds.

I'll test the 4g/3g hand off next time I am in a 4G area.
[Samsung Galaxy Nexus] TEK112:
Are you sure that it wasn't -93 dbm of 3g before the flash and after the flash changed to -120 dbm 4g?

That seems very irregular if 3g changed this much.
[Samsung Galaxy Nexus] qwho:
Here is a screenshot of my battery performance after flashing the leaked radio. This is by no means conclusive, will continue to test. Could be that I just never opened whatever might have been sucking down all the battery before... but man, this looks promising.
[Samsung Galaxy Nexus] DeWitt_A:
Call me happy with the new Radios. I was having a problem when I would walk into a weak signal area in my building and it would stay in 3G for quite a while after I returned to a "good" area. After the update it switches back to 4G almost immediately.

Using speedtest, (Same location, same time of day) my 4G download speed almost doubled. Was low 6's yesterday, now 12.2 Mbps with the new radios.
[Samsung Galaxy Nexus] aohus:
been waiting for official word of 4.0.3 update but none. i think i may flash this leaked radio kernel.

i can always go back to stock kernel no problem correct by flashing it via CWM?
[Samsung Galaxy Nexus] madpoet:
I'm sitting beside a coworker with a Rezound. He has 2 bars on 4G LTE. I have about 3/4 full 3G and cannot get it to find 4G at all even if I force the radio mode with LTE Switch. He is getting about 9Mb down on Speedtest, I am getting barely 1. I am about done with this phone :( I've tried every radio tweak known to man, it just seems like it sucks. Badly.
[Samsung Galaxy Nexus] TEK112:
Correct...
[Samsung Galaxy Nexus] kangxi:
4G has been having issues today.
[Samsung Galaxy Nexus] pjd2011:
I have posted in these forums before about how bad my 3G signal has been with the phone. While at my home for the holidays I could not even reach 1mbps down and past 50KBPS up. I'm in Florida on training trip and have had amazing 3G speeds. While heading to the airport my 4G speed topped out at 36mbps!!! Blazing fast. I can't comment on reception with 4G, though, as I don't have anything to compare with.

I'm guessing it was just the tower at home. Even though other phones were flying by.

These tests were with the 4.0.3 Radios

3G at my home. Again I was to the point of taking this back with these speeds.

3G in Plantation, FL

4G signal from Indianapolis
[Samsung Galaxy Nexus] madpoet:
Doesn't explain why he would be getting 4G and I couldn't :(
[Samsung Galaxy Nexus] aidman:
I'm pretty sure -120dbm means no signal. So if you're seeing -120, and getting data, it must mean the signal measurement is for 3G and you're using LTE or visa-versa. A google search seemed to back up my theory.
[Samsung Galaxy Nexus] TEK112:
No signal means no signal. I have had data connect at -140dBm.
[Samsung Galaxy Nexus] CBMC:
I didn't think the scale went that low. I thought -120 is no signal.
[Samsung Galaxy Nexus] TEK112:
Before you completely toss it follow the route I am taking. I had them swap my sim yesterday. It has improved slightly, but if it continue through next week I am going to swap out the whole device. I have until January 15th to return the phone and if by then a new device, new sim and OTA doesn't fix it, I will sadly return it.

---------- Post added at 09:20 AM ---------- Previous post was at 09:09 AM ----------

Like I said, no signal means no signal. Showing any signal strength indicates a connection. Now don't get me wrong, you are not going to check email on -140dBm or stream music at -120dBm. We are talking basic packet transfer and even then it will be flaky. At that low of a signal, wind is a great factor in a stable connection. On eHRP at -120dBm I can successfully make a phone call and send texts. I was at -140dBm so briefly I could not test it.
[Samsung Galaxy Nexus] kerms:
I believe it shows -120dBm when you go into airplane mode, which is why some may think that means no signal.
[Samsung Galaxy Nexus] ToyTank:
I can verify I am at -120db at all times in my house.

I am not in a 4G market area.

I can call text and get flaky data speeds down(~50k) and decent upload(600K)

I am about ready to return this phone. Poor radio performance and having to toggle airplane mode several times a day to get data is BS. If I go stand under the tower I get good speeds if I can get it to connect.
[Samsung Galaxy Nexus] TEK112:
Go into settings-wifi-press the menu button-advanced-WiFi frequency band and make sure it is set to auto.
[Samsung Galaxy Nexus] aergern:
System Info Widget on mine shows -93 dBm but I get 14-16M down and 5-9M up in my house ... I get better transfer rates outside of course. I saw this same behavior of slower speeds with the Thunderbolt for the first couple months I had it ... BUT 8 to 9 friggin radio updates later the same phone in my house was regularly at -62 dBm and my speeds were twice what they'd been when I first got the phone. I don't know why it takes so many radio updates to get it right but apparently it does.

I wouldn't give up on the GN just because it's the first Android 4.0 LTE phone on VZW's network .. you adopt early and you have to go through these things .. it is how it is. I'd say by end of Feb. most of this silly stuff will be fixed and everyone should be happier.

Also, just at the store *I* went to ... there were at least 80 people in line ALL for the GN. This is one store out of hundreds ... and there were 3.7M Android phones activated in the 3 days before Xmas and in the 2 days afterward ... imagine how many new VZW LTE customers fit into that 3.7M. I think maybe VZW is a bit overloaded ... just look at the two major outages since 12/15 and you might think the same.
[Samsung Galaxy Nexus] TEK112:
Hard to disagree with that logic.
[Samsung Galaxy Nexus] clichename122:
Before, I got -85 to -90 at home. After installing these new radios, I get -100 to -120. :(

Does this only help with stock roms? I'm running Android Revolution HD.
[Samsung Galaxy Nexus] TEK112:
Are you sure you weren't on 3g before the flash and after the flash you are now seeing what little 4g there is in your area?
[Samsung Galaxy Nexus] clichename122:
I'm pretty sure my area is supported. I had a bionic before this, and I always had -70 to -85.
[Samsung Galaxy Nexus] TEK112:
Regardless, did you confirm which network you were on? You may have only been seeing 3g before and this update could have let you pick up 4g. This thread has already shown the Rez and Bionic get better signal that the Gnexus so I really wouldn't compare the two as they all have different radios.
[Samsung Galaxy Nexus] clichename122:
Yeah, I was on 4G. :(
[Samsung Galaxy Nexus] TEK112:
Flash back the stock radio and see what happens.
[Samsung Galaxy Nexus] AlphaVFR:
Tested and it's working for me. About a 5 to 10 dbm decrease for 4G. 3G stayed relatively the same. Switching from wifi to 4G also seems faster now.
[Samsung Galaxy Nexus] aergern:
Nope. I get better reception with the new radios and I'm running ARHD 2.1.2 while the wife's GN is stock as a rock and not even rooted .. unlocked yes ... rooted no. She sees 1-2M down and 1M up slower then my phone. NOW .. if she would just give me the damn thing for 5 minutes I'd root it and flash these radios. ;)
[Samsung Galaxy Nexus] scribbles395:
You said it. I had the tbolt, bionic, razr and now the nexus. The radio in this is horrible. I flashed the new radio and no difference except for faster handover.
[Samsung Galaxy Nexus] aergern:
Yes, BUT ... it took the Thunderbolt months of updates to get the LTE connection right. SO ... it may not be the radio but the firmware ... the leak is a step forward but patience might be required.

Also, VZW announced they are making quite a few updates/upgrades to the LTE network now and over the next month ... they got a metric ton of new 4G subs in the last 3 weeks and their network IS not handling it. My buddy in StL is regularly getting 36M down and 12-16M up ... WITH his GN so it can NOT just be the radios but think what you like. I know in the tech heavy Bay Area where I am that the connection varies wildly but that's because of how many are connected to the network. Like I said in an earlier post .. quite a few traded up from their 3G Droid 1, Dinc and whatnot to the GN as they were waiting on it since last summer most likely. I would say the radio part of this is only a 1/3 of the reason issues are occurring.

Again, early adoption means a bumpy ride for a bit. It is what it is.
[Samsung Galaxy Nexus] scribbles395:
I'll hold on for the ride. I understand that as with any new technology there are going to be glitches that need ironing out. I hope sooner then later.
[Samsung Galaxy Nexus] jhpk13:
Comparing the GN next to the Razr, speetest is about twice the speed for the Razr compared to the GN with stock radio. Anyone happen to do a side by side after the new radio?
[Samsung Galaxy Nexus] jjrudey:
With the new radios I had -120 in my room. The old ones are a little better actually, but my old Droid pretty much always had -90 or better. I'm also in an LTE market so I don't know what the deal is.
