My nexus keeps dropping all data! After a reboot ill have data for 3 minutes then bam its gone same with 3G! Is there anyway to dia *228 to update your roaming stuff or something i have tried eberything i have roaming on and have done multiple restores any ideas

add *22899 as a contact and dial it from your contacts. It will update your prl. Maybe this will work for you.

No good anything else?

I get the same thing. I updated my radio and seems to work a little better but still get data drop.

Well, I had the same issue a couple of days ago. But the issue was not with the phone....it was with the signal tower. You should call Verizon and see what's going on. Sometimes there are areas where 4G signals are also weak. I spent one night at South Beverly Drive and Wilshire in Los Angeles, and I got no 4G signal whatsover. If you live by the area where there are lots of tall buildings, you probably won't get any data signals. So you might wanna check both.

My first Nexus would lose all signal at random, even if I was in an area with 4 bars of 4G. Swapping the SIM card out didn't work, so I swapped the phone out.
The new one works perfectly in a 4G area, but in a 3G-only area (like where I live), it will drop its data connection a lot. It keeps voice, but the 3G icon disappears. Switching into CDMA-only mode didn't help. Flashing the 4.0.3 radios didn't help. I use a lot of data, so I'm left wondering whether I should swap this phone out, or just give up on having a Nexus.

I don't experience any connectivity issues so far(I live in Fullerton, California), and my brother, 2 of my friends, friends' friend, my girlfriend and her little brother!

It started after the 4G outage... Could have that hurt my phone? I highly doubt it but you never know...hmmm to verizon when I get back home from vacation
EDIT: Been on CDMA and it seems to be working, low bars, but seems to be. Maybe its verizon's network where I am, ill check again tomorrow. Hope its working this is really making me sad I really do love my nexus

Could it be your modem/radio? I'm using a GSM nexus, but I had loads of signal drops on the KK1 modem till I updated to the KK6 modem

I was wondering the same thing. Mine has been sporadic since the outages while my wife's charge is rock solid. I have tried to lose a signal with her charge and it won't do it. 3g is awful on my nexus. It'll be there for a minute or two then gone. Really frustrating cause I love this phone

I've been seeing the same thing but it seems to only happen when I'm on LTE. Example...I just went out and was in a 4G coverage area with full signal. Around every 15-20 minutes I would lose all form of signal for about 30 seconds and it would come back. I've found that switching to CDMA only allows me to maintain a solid connection. During the period that I was experiencing the outages my girlfriends RAZR has been rock solid. Looks like I may be spending some time on the phone with Verizon tomorrow.

My take on Galaxy Nexus problems (VZW)

I've had this phone now for less than a month. I know it's not a long time, but I think I've got a pretty good idea of how this phone performs. I have not rooted this phone, I am on 4.02 and PRL 15119.
1. The signal problem:
Coming from a Droid2, the first thing I noticed was one or no bars where I used to have full! I was losing data all the time, until I switched to CDMA only. My phone kept switching to LTE and back again, I spent more time in hand offs than connected!
I had the opportunity to have my Nexus, a TBolt, and a Maxx all in my basement together and did a few tests. All three phones had trouble holding LTE here when I was able to run a speed test, they all performed similarly, between 1 and 2 Mbps. When all three switched to CDMA, they displayed one more bar on and off than my Nexus, but showed similar pings and speeds.
I spend a lot of time in my basement and have never had troubles losing data (CDMA only) even though it displays 0-1 bars all the time.
Now, I do occasionally have problems with data, but it's nothing new to me. My Droid2 would show full signal and just not load a page or drop to 1x in locations known to be strong service.
I have not had this problem with the WiFi hand off back to cellular data. This phone switches faster than my Droid2 ever did. Like, by a lot. I work in no service building. Every morning I turn my WiFi on and just turn it off when I get in my car to go home. Usually I have cellular service before I can even turn off the WiFi.
I read a lot of reports where someones Nexus would be outperformed in a 4G speed test by another Verizon 4G device. Not the case here. My tests were constantly the same when comparing between the Nexus, TBolt, and Maxx.
I stopped in the Verizon store and two of the sales dudes had 4G phones, a Razr and another Galaxy Nexus. The Nexus guy was rooted on 4.04 and couldn't break 10Mbps while Razer guy and myself were fighting for 40Mbps.. Maybe there are some lemons out there
All in all, I may have gotten a good device (made in China, go figure), but I do not believe there is a real problem here. If this is your first android on Verizon, I can see where you'd think there are problems. Whenever I pick up my phone, I just ignore the bars and use it. It always works. Even in 3G, this phone loads pages WAY faster than my Droid2.
2. Battery life: I am not a real heavy user. There are times when I'll spend 20 minutes in the bathroom playing angry birds or reading threads, but that's about it. I got the Verizon extended battery before leaving the store with my new phone. This battery has 200mah more juice than the extended battery in my old Droid2.
I think this phone get's great stand by time, I got it to go 3 days off charger with a few calls and texts every day and a little bit of angry birds
On a whole, I'd have to say it get's as good or better life than my last phone.
3. Random reboots: I was constantly pulling my phone out of my pocket to find that it was off. I had gotten quite concerned after reading all the posts about crash reboots. It wasn't until I set the phone down while booting it up that I saw the screen shut off. I knew something wasn't right here and reproduced the shut down by smacking the phone in my palm while it was booting it up.
After looking closely, I noticed the battery would move up and down in its compartment. I solved this by taking some folded paper and taping it to the bottom edge of the battery. Pushing the battery up into the contacts on the phone. I also added some tape/paper to the top of the battery so the cover is pushing it down into the compartment.
Obviously I can't speak for everyone, but I haven't had a single crash/reboot. Just this battery connection problem.
4. Slow screen rotation: I have noticed this, it is VERY annoying when you first get the phone. Habit is to flip it landscape BEFORE launching the app you want to use. This is why you think it's so slow, because the home screen will not flip, it just refuses to. In any app, it flips just like you're used to. A non problem that I'm sure will get fixed.
5. Screen banding: I tried looking at the blank grey screen on any brightness, I could not get the bands I kept reading about. I guess I got lucky!
6. Overheating: I read this phone will try to use 2.4 and 5GHz spectrum's while on WiFi. The first thing I did was set it to 2.4 only and have not had any issues. I use WiFi 8 hours a day every day with out the phone getting hot. I also use the hot spot almost every night, as I don't have a land line internet at home. Never an issue, once again, to the touch this phone was not as hot as my Droid2.
I really like ICS and this phone seems like a keeper. I hope this inspires someone to go out and buy the Nexus!!

Over the weekend I went to the Verizon store to compare the vz nexus signal. Turns out every device with lte read -60 and then nexus -80. But there was one lg phone that displayed both signals at the same time, 1x and lte read -60 and -80. So I wonder does Verizon lte phones actually never show lte signal and always show cdma even when connected to lte?

Just earlier today I compared my Galaxy Nexus at -110 to my dad's Rezound at -80. Side by side at the exact same time. I'm sorry I didn't take a picture.
I'm unrooted stock 4.0.2 right now.

Silly question but did the salesman with the Nexus have LTE on?

How in the world could you go 3 days on a 2100mah? The most i can get is maybe a day or day and a half. Usually its under a day as i use my phone alot.

Lost the link but basically non ics phones show 3g signal instead of 4g or something like that. Its a different signal type that's why the gnex always shows less because its showing its actual signal

i honestly think its a hardware issue, but i have read all the threads and there is nothing concrete... my phone works perfect on 3g but i switch it to 4g and it just looses signal i could have 3 bars and then all of sudden it just looses all signal, it does not switch to 3g..im in a good 4g coverage area as well. im really angry and i dont want any other phone but the one i have . I hate blur so forget motorola

If they are not ICS devices, they do not show the LTE signal.

This was achieved over a weekend in a strong service area on cdma only. I was at a solid 3/⁴ bars the whole time. I was at a buddys house for a lan, so i was doing my surfing on the computer. I was doing most of my texting in google voice on my pc, so the only use the phone saw was calls and bathroom browsing lol.
Yes, the nexus measures signal differently and this is why it cant hold 4g, it thinks the signal is too weak and lets go before it should. If you had a vzw droid before and know where the strong 3g is, set it to cdma only and see how it performs compared to the old phone. If your getting data drops and dropped calls where you didnt before, then exchange your phone.
Ive read there is a way to force lte only, this would be the best test. But i cant remember how to do it.
Want to add, the ics keyboard is the best one ive ever used. Also, speaker volume on this phone is plenty loud. I have had problems with call quality when i have no bars. Just does not sound good and hard to unserstand people. When i have a bar or more, sounds great. Like theyre in the room.

Definitely lte. I am not sure what vzws theoretical max speed is on 3g, but in our area, max is about 1.7Mbps. I know theoretical is no where near 10Mbps.

Could the differences have been due to your radios? I'm on 4.0.4 with the new radios and I don't break 10Mpbs.
The speed is fast enough for me and I don't remember exactly the speeds I had on the earlier radios. I vaguely remember breaking 10Mpbs at times. I might reflash the older radios and do speed tests.

I'm happy to report I have zero problems with my VZW GNex since day 1

Now i didnt see these guys screens, i dont know what they were using for testing or what server they were connecting to. He told me hes never been able to break 10 megs. For all i know he rooted and flashed on day one. I cant imagine the members of xda would overlook something so obvious, but who knows. Give it a try eh? For reference all my mentions have been using the official speedtest.net app and chicago servers. Im tempted to root, but im waiting for 4.05 ota and have no idea how to do it. Ill get there eventually

I've found that LTE can vary wildly in speeds. You really need multiple tests with multiple phones at the same location/time.
That said, I saw a huge difference between FC05 and FA02. I found that the best combination for my phone was FC04 on the CDMA radio and FA02 on the LTE radio. It's a good 2mbits faster and much more stable. Signal in my house is borderline, so you really see the difference.

Thanks for the suggestion.
I flash the FC04/FA02 combo and in the spot near my house where I am disappointed, 4.5Mpbs down / 2.5 up, I got pretty much the same results. One difference I did notice is that the hybrid combo is slower to switch from 3G than FC05/FC05. I toggled LTE to force 4G connect.
I flashed back. Eager to see what 4.05 brings and also if the latest official IMM76K brings new radios.

Um, it kind of is since most of us come here for help.
Also, if your read the OP he was not complaining about issues as much as addressing them.

3G dropping constantly

So my GNex loses the 3G signal every few minutes, or sometimes more often than that. It dropped twice while writing this post. This is pissing me off more than I can put into words. I know others have had this issue, but I think that the connection problems are increased because of where I live... this either doesn't happen to me when I'm at work in another city or happens so little that I never notice it.
Is there anything I can do? Do you think it would do me any good at all to call Sprint?
I'm using the stock FD02 radio running CM9 with Samurai kernel and the Trickster MOD. But this happened just as often before I even rooted.
Help appreciated!

Tell sprint to give you a network extender. If it is the signal at your house that's all you can do.
"Long is the way, and hard, that out of hell leads up to light."

It is a known issue with the Galaxy Nexus that the signal is not the greatest. That is why I left Sprint for Verizon (only to have the GNex).
I had kinda decent signal with my EVO, SGSII and iPhone with Sprint...so I thought getting the GNex, with known signal issue would be the death of me. So I got the phone I HAD TO HAVE with a carrier that would at the very least "boost" the weak radios that Samsung has....and for the record, I have killer signal, unlike I've ever seen before....albeit, I'm paying out the ass for it.
(roughly 20 buck more a month then Sprint)
Now if I were in your shoes, I'd call Sprint. They might be able to trade phones with you, if you're willing to part with your GNex. If not (like I couldn't)...you may want to look into the option posted just above my post, or even do the unthinkable......
....go with Verizon.

I've heard of this, but I thought it was only for actual phone signal, not 3G. It's the AirRave thing what you're talking about?

It is the AirRave that he is speaking of, and it will increase your 3G yes. I had a friend who got an AirRave cause once inside his house, there was zero signal. Turn the AirRave on....and beautiful signal throughout the house (pretty much).
He also got it free.

I've never had sprint so I don't know if their network extender repeats EVDO or not. Verizon's does.

May be that's because the CPU clock is set to 350MHz as a base limit which causes the phone to drop signals when not in use. Try increasing the base limit to 750MHz and see if it make some difference. You can use SetCPU for that.

I'm having the same losing signal problem as well, and I do have the network extender. My problem is the phone says 3g on top but it is really only using 1x. Its a defective radio, Sprint is replacing my gnex.

Sprint is sending me an AirRave so I guess I'll have to wait and see how much it helps.

I have problems with that too. Only in low signal areas though. The data will kick off if I'm in an area that barely has 1 bar for example.

Note that data toggling on / off usually will kick it back on.

My colleague had this exact same problem and he fixed it by flashing a new baseband (radio from a post in this forum); you may wish to try this. And supposedly the Wifi performance will improve too.

While it is worth a try there are two separate radio issues at hand. One is a faulty device and one is a bad baseband.
Also the baseband won't affect wifi performance for the better or worse.

Am i the only one with 4G problems?

Looked in General and Q&A and can't find anyone complaining about 4G reception. This stupid phone doesn't hold 4G indoors ANYWHERE I go. My Galaxy S2 never had problems like this. This phone is always switching to EDGE. ALWAYS!!! Really causing me to regret my purchase. Also, my "4G" speed test has never gone faster than 3.5-4Mbps down, where my GS2 averaged 9-15Mbps. Only flaw I have had with this phone. I read Verizon users are having the same issues with their GS3. This damn phone annoys the hell outta me and hope the Galaxy Note doesn't have the same radio as this because I can't wait to replace this phone. I love it and how fluid the ui is, but I pay for the 10GB data plan, but this idiotic phone doesn't allow me to use it. And I've had it replaced twice. Gonna replace the SIM later today and see if that helps. So, am I the only one? And I live in an excellent 4G area according to T-Mobile.

This may not help, but could be worth a try.
Open the dialer and enter *#*#4636#*#*
Once u hit the last * it should open up a menu. Select Device Information, scroll down a little and there should be a box to click on. Choose WCDMA Only and see if you can get onto 4G now. If you can get 4G, you can go back and choose WCDMA preffered and see if it acts ok on this setting.
Worth a try at least. Good luck!
And have you called tmobile to see if they are having problems with any towers in your area?

I'm having some similar issues. I can get 4g indoors, but seems to switch around without even moving the phone. I'm wondering if it's a "feature" of the SGS3. Uses less battery to hold EDGE/3g and then when it detects data transfer, switches to 4g... I dunno.
That being said, you can try installing the new OTA which has a new radio. Or if your rooted etc, flash the radio zip Wild put up. I've noticed some improvements with signal strength, but it still seems to swap based on what I'm doing.
Anybody more knowledgeable have any info on this "smart data management"?

The phone will only stay at 4G during data transfers, while idle it'll drop back to 3G. I don't think it should be dropping to edge/2G though.
Did you try the method I mentioned in my other post?

Yes I did and thank you for bringing that to attention , I don't know how I let that slip my mind, I used that setting to fix my last two Samsung phones, Nexus S and GS2. They both would do this just not as bad as the GS3, now the phone holds its 4G/3G much better with WCDMA only turned on. Now I have zero gripes about this phone.
Anyone know what the difference is between HSPA:10 and HSPA+15? Is the latter the HSPA42 T-Mobile advertises?

hold the phone upside down. works wonders i swear lol. especially when you're trying to download something.

I have the same issue. I'm in the SF Bay Area and even though TMobile's site has where I live and work as dark green (excellent 4g) I am lucky to get even one bar. Half the time I get network errors. Anyone else with TMobile experience anything like this? Any chance it's something that'll get resolved before my 30 day return period ends?

do any of you have other tmobile phones to compare signals with? if so, do that and if there are major differences talk to a tmobile store about getting a replacement.
these might be isolated incidents, because the majority of people are getting fully functional units

my data speeds are *top notch*.
you are either in an area thats out of tmobiles footprint or have a defective unit.
best bet would be to wait till tmobile actually gets the GS4 on display in the store.
when they do, go to your nearest tmob, and do a speedtest.net comparison with the demo model, and yours. if they are similar, then your part of the bay is legacy; if there is a big difference; 3,4 5 etc megabit difference; your unit may be worth exchanging for a new unit.

What part of SF are you experiencing this? My GF lives by the ballpark & she won't switch with me if she gets ****ty service.

I have excellent reception (bars) on my S4.
Way better than my Note II.

I let you know. When I get my phone next week. I do a speedtest and a screenshot of the phone signal in the settings menu.

Still no signal inside my workplace. Will do more tests. It does seem the signal is more stable, but it's only been a couple days.
Also, 4G LTE flashed for a couple seconds at my house. I live in the D.C metro area. Nice.

I have the HTC One in the Phoenix market. LTE is difficult to find more than a few bars on. 4G HSPA+ has been very easy to get full bars on.
I'm somewhat convinced T-Mobile is still working on building out in even LTE and re-farmed markets.

Its funny how T-Mobile improves their network and yet many years later I still don't have service in places where I had no service maybe 5-6 years ago. And on top of this I noticed even more dead spots. I think T-Mobile should be working on that along with building penatration.....I would much rather have 3G everywhere then LTE almost nowhere.
Lately it became very frustrating since my wife has no service at work, i have no service at work, and i recently moved to different location and still no service....and God forbid I loose my wife in the mall, I have zero chances of finding her because no T-Mobile service inside.

Just got my S4 today and did not realize theres LTE where I work (fremont) which I never saw on my note 2. Even went out to lunch and was still getting LTE the next street over. So just to test I'm now back on my note 2 and it is not picking up LTE at my work. That tells me the radio on the s4 is much better.

I get bars and shows signal strength of 3 to 4 bars and i can make call but no internet in certain areas all around Los Angeles County/Orange County/Las Vegas/NYC. To test it i had my buddy go with me with his LG L9 and my buddy with his LG L9 phone would work fine on the calls and data/internet meanwhile my S4 would only get calls but no data as if it was a deadspot. i would have to go around like 1/4 or so before it would work again. its really strange not to mention annoying. I noticed this started happening to me after i upgraded from MDB to the MDL baseband and after i unlocked the phone using the "debug service menu". i wish i knew someone else with a stock TMO S4 to test my findings out more. I also cant wait for more tmo S4 modems. ive been thinking of ODINing back to stock MDB to test my theory, but i have just been lazy.

i think it was a TMO LTE tower upgrade issues. after doing the Settings > More networks > Mobile networks > Network mode > and switching between the WCDMA and GSM one or the other now will work. better to have some internet than no internet, weird how the S4 just wont switch over to the working GSM internet if WCDMA fails....i guess when they coded it they figured if u have bars it "should work in theory" but they were wrong ...personally i think this should be considered a "bug"

I thought I was the only one. I found that if i keep my diztronic tpu case on while in my pocket it destroys all signal for some reason. I take it off and its fine.

I further tested my theory and went without my case all day. It didnt appear to do anything different at all. I am on CM10.1, I think I might go back to stock for awhile to see if it changes the fluctuating signal issue.

Just curious on how everyones signal is and which baseband they are on?
I'm on M919UVUAMDL and I have seen up to 15% of no signal while my S3 had 0 signal loss in a regular day.
