Are you rooted?
P.S. Your wife works in a low reception area?

Looks like this is becoming an issue, there's two existing threads on it so far:

I'm hoping there's a fix soon because I love the phone and don't want to return it.
Edit: Just happened to me again sitting here at my desk with good signal.

Nope not rooted.

I know the Nexus had a crappy radio but I never lost connection with it, especially at my home where I lost data/cellular connection twice so far

Unfortunately I cannot say that I have experienced this, while I am at work I have my Wi-Fi on 100%, and whenever I step outside of the office to use the bathroom, or to go to the vending machine (Wi-Fi signal still barely reaches), There have been several times that it would drop the connection because the signal was too weak. However as soon as I got back within proper range It would reconnect immediately with no problems.

well I called sprint last night and the reprovisioned everything. They said this is the first that they have heard of it and are sending the info to sprint and samsung. I will report back later if this fixes her problem. I doubt it will though, because other post have shown that this is just like doing a profile and prl update.

I just tested my WiFi again at work. I am standing next to the WiFi Router, and cannot get a connection unless I reset the phone. I am frustrated. I cannot reset my phone everyday when I come to work just to get a signal.
I just jumped ship from AT&T's iPhone to this, and need to decide where to go next. Verizon Bionic?

I had same problem happen last night. Showed the international no symbol and didn't get a signal until I rebooted.

nexus dropping connection

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
Sent from my Galaxy Nexus using XDA App

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.

Hows the radios working for ya??????

Ok, ready to pull the trigger on a Note 2 but having the ET4G and the issues with reception, Im a little hesitant on Sammy phones now.. I love my Epic T but low up and download speeds kill me. Im missing calls and its not showing up in my call log and texts messages too. I have friends who have the GS3 and some love it and some hate it. Two friends can sit side by side with their SG3 and have totally different reception, I dont get it. I hear the radio and antenna are the same from the GS3 but wondering if the size of the antenna in the Note 2 has changed and if so, is that change enough to help reception issues?
Any input from those who just got one would be greatly appreciated.

I haven't seen lte, but 3g is just as good as you can get on Sprint

I too have the epic touch, a d then the s3.
Although I cannot comment on note 2,because I don't have it yet, the s3's radio is much better than epic touch.
Instant gps lock and no LOS

I too have the E4G and have just been patiently waiting....I almost jumped on the SIII, but thought I would wait. I think GN2 is what I have been waiting for.
The missed calls (never ringing), daily lock ups and reboots are driving me crazy!

I picked mine up this morning, I'm very happy with reception so far, seeing a lot of improvement over my old epic 4g, and the download speeds seem a tad inproved in my commonly trodden areas

I cannot hold a steady 3g data connection. Network mode is set to cdma/lte/evdo and it keep bouncing on and off for 3g. just came from the Evo lte and that phone at the same spot can hold a 3g eHDRP or Evdo just fine. Going to see if sprint can reprovision this phone for me. If this is a normal thing with samsung phone then I have no choice but to return it.

Update:
Phone is now connecting better after switiching perferred roaming from automatic to sprint only. All my previous phone have no problem when set to automatic roaming. Well at least now my data is not dropping like it was. My real test by putting it on sprint only (home on samsung's phone) is to see if it will connect to LTE where's LTE is available. I will find out after work when I'm on my way home since I get no LTE connection here at work.

Anyone coming from the galaxy s3 miss the simultaneous voice and data? I can't believe this phone can't do it unless connected to lte.

How is the wifi? The S3 was weak on stock rom, then improved with AOSP roms.

NYC and Data Coverage

So I live in the city. Right now I'm using MOAR v4.01 and I cannot achieve a connection other than 1x no matter where I am in the city. I had this problem on other ROMS so I don't think it's MOAR.
I was using the Anthrax Aosp rom a few months ago and noticed I achieved a 4g connection on the upper east side but ever since then I cannot get higher than 1x.
Is there anyone else in NY getting a 3g or 4g connection? Does anyone know what I can do to try to fix this? I am using the MD4 modem (had the problem on MB1 too) and update my profile and prl often. I am really getting frustrated paying for services I can't even use. I am hoping that I won't have to unroot and reset my flash counter to bring the phone to a sprint store.

I'm nowhere near NYC (in fact, Southern California is pretty much as far away as you can get from NYC without going to Alaska or Hawaii), but it sounds like Sprint might be updating their network. I know in many areas (myself included), Data services were extremely crippled when they were installing 4G. I would regularly get 1x in areas where I would get decent 3G. Then a few weeks later, the 3G was back. Then a month or so later 4G was up and running (it's pretty nice here at my work desk). Others have reported similar issues when the network is being upgraded.
So maybe it'd be worth a call to Sprint to see what's up with them. A part of me doubts that most of NYC would be upgraded at once, but maybe in your area there's work going on. It's worth a (relatively) quick call.

Yes, I get 3g and 4g depending where I am. I'm stock rooted md4.
Had that issue once but update profile and prl over wifi fixed it for me.

I emailed them and they told me there is network outages in my area, but then the guy above me just said he's getting a 3g and 4g connection. Sprint really frustrates me. When I got my phone, it would say I was connected to 3g but after doing speed tests I would only get about 115kbps down. Now I'm using MOAR and it shows 1x and if I do a speed test on 1x its about the same. However, I used to get a 4g connection on 44th street and 6th ave but now I don't. I think I'm gonna go to the store today and ask them. If they tell me to bring my phone in I'll have to unroot it and reset the flash counter :/

Yes, certain spots in lower Manhattan I get signal but can't use the service. It just don't work. Text won't send or calls won't go thru.
Yes sprint turns on and off the 4g.

So I found out what was causing the issue. I went into the ##3282# menu and navigated to Others > HDR/1X Selection and turned it to Hybrid mode and now I can access 3G and I'm gonna test 4G after work.

Anyone notice their service getting worse?

At first I thought it might have been my rom, but it seems it's happening with my GF's note 2 also.
Coverage we used to receive in some areas is almost completely gone. It will show signal and the 4g symbol but basically have NO internet service whatsoever.
On a better note, we've been receiving coverage in some areas we don't usually have it.
I'm hoping this is just a temporary thing due to the attempts to upgrade towers for LTE.
I don't know if it's because of the UVBMB4 update, but t-mobile service has been pretty crappy lately. Period.
We're in the San Gabriel Valley area.
Link for older UVALL4 modem below, people seem to experience better service
http://forum.xda-developers.com/show...php?p=36786363

I believe my service has suffered as well. Before the last update that enabled our Lte radios, I had great speeds, now it's slowed Way down. I'm in San Diego CA. Hope that it's just as the Op said, LTE towers being updated and what not.

Definitely have noticed a deterioration of service over the past month here in NYC.

Its because for some reason that new LTE APN is slow on HSPA+.. unless you have LTE in your area switch to the EPC APN. You can find the settings online. Its litter ally consistently a difference of 6+ mbps I have extensively speed tested lol..... click thanks if this helped

I also had problems even with old apn.
Flashed previous radio and service is top notch again.
Sent from my SGH-T889 using xda premium

Same here, I thought it was rom related.

YES! My service has sucked royally for the past month or so. Data latency/hangups/slowness, and the signal will just completely go away sometimes. I noticed that it started as soon as I flashed the most recent radio too, I'm about to go back to the old one.

Count me in, even my regular phone reception went from 4 bars no 1 or 0!

Can anyone point to towards old radio to flash? I go from no signal downstairs to full bars upstairs...theres an obv issue with new radio.

Yup I've noticed this beginning this week I've made zero changes to the phone. I used to get full bars at work and this week it bounces between full and 1 bar regularly. Theure messing with towers for sure

I'm also experiencing significant decrease on data speed. Has your data speed improve after flashing with older radio and APN setting?

I was getting about 9/0.6 and with flashing back Im getting... 14/2 Though Ive been on HSDPA 15 & 21. Though Im not getting 4G as much, but it was sporadic anyways and I lost signal...and now I am not. So, Im happy now even though I am on 3G. However... in my corner big red has same problems as they wanted to not have tons of towers in this corner and theres only a ATT Tower....for a decent distance. basically reception fringe. though I am a new subscriber so i haven't experienced normal TMO, I literally got my device yesterday around 6pmish but it def wasn't normal and flashing previous radio did fix it like it solved everyone elses issue

my problems started last friday. i have limited to no service at all; no data, no voice, even no signal at times (circle with line through it, not just no bars). when i do get a signal, the phone refuses to register on the network. when im at home, i have intermittent service. i miss calls, texts wont send, if i do get a working call, it drops after a bit. there are times when it works fine, even on LTE but it never last long. went to the tmo store last night and they gave me a new sim which didnt do squat. already done the factory reset option (twice). phone has never been rooted, all stock. im in the KC metro so not like in the middle of nowhere. they said my next step is a warranty replacement phone if the sim didnt help. not sure if my problem is at all related to everyone elses in this thread, but yeah, service has sucked.

One of the issues, especially if you switch from 4g to edge to gprs a lot, is a setting in the new modem.
It's something called acquisition order. It has 3 settings:automatic, gsm_umts, umts_gsm. In short it tells the phone what kind of network to prefer. It will search for and use that type of network first.
Prior to the latest update it was set to auto. Now it is set to prefer umts. For some reason this has caused an issue I've come to call phantom 4g. Where it'll say 4g with no bars and no data service.
That is my guess. I'll look into it further.

Thanks guys for the heads up on switching to an older radio, I dont have LTE in Miami yet and was having slow internet for the last 3 weeks, I just switched and wow! What a difference. I'm also using the Epic APN.

I also noticed that speeds were degraded after the update. However, there is a simply fix to make your web a tad bit faster....
Go into your network settings, and switch your mobile network from LTE/4g/3g/2g to just 4G/3g/2g
your device will stop looking for an LTE connection and will just utilize HSPA+
Made a world of a difference on my own device. Connecting to the play store, opening web pages, everything was right back to where it was before the update.
Obviously if you live in an LTE area, there is no need to do this...

So I'm gonna be a noob here for a sec. When people say they are flashing the previous radio (I'm referencing the link that was posted) are people just flashing the modem from the section under the most recent? (the one with the January date on it). Just thought I would ask. Better safe than sorry. Thanks!

Yup, radio is synonymous with modem in this case. UVALL4 is the previous version.
