Is this the infamous Nexus 3G problem?

before I got my phone I read about all the 3G problems people were having.
when I first got my nexus, there were no issues at all. no dropped service or connection.
I'm in a 3G area (looked at tmobile coverage map) and I see no reason for this to be happening.
my phone will show that I have 3G connection (UMTS) but when trying to use anything that requires a connection, it fails.
on the other hand, HSDPA network works fine and so does EDGE.
I got my phone over a month ago and this hasn't started happening until recently.
I'm always on EDGE network now and if I'm not on EDGE, I have to be on HSDPA in order for me a to send messages or use data connection.
UMTS is broken and does not give connection. I want to call HTC and see if they can replace it but I don't think they'd do it.
anyone else have the 3G problem? I'm sure a lot do, but is it only with UMTS?

This is not the "3g issue" everyone talks about. This sounds like you are either having network issues in your area, or did you flash a new ROM to your phone recently?

I had been on a CM test build and hadn't flashed a rom in a long time.
network issues isn't the problem because my friends G1 yesterday had 3G and I had EDGE.
I don't think it's my SIM card either, not even two years old.
I'm tempted to call HTC because this happened out of nowhere after a good month of no problems.

99% of the time it's a carrier issue.
When the number of users on a carrier grows or jumps on the carrier, the tower signal shrinks it's radius. And if you're in two competing tower areas, then your signal might drop/fluctuate because the phone is swapping between them.
Nothing the phone can do about it. It's probably your carrier issue.

how can that be when my friends right next to me have full bars and 3G while I'm on edge?

Change your settings to WCDMA only then.

I've tried and all I get is no connection or occasionally hsdpa.

I have experienced something like this. I am unrooted and few weeks after having the phone I would see a 3g symbol but be unable to access any data. It has been very frustrating once but generally it kicks in again with a reboot.
A similar issue since installing froyo is that the stock browser wouldn't connect. Other browsers and applications could access data but the stock browser couldn't. It started again later but I now use xscope.
I love android but I hope that the continue to work on its stability because it could be improved

so is your 3G working now? I'm just going to call HTC and see what happens.
I've tried WCDMA only, flashing a radio, and anything I can find on the web but no luck.

Have you tried modifying your build.prop? If not, do a quick search and see if modifying it helps...

3G dropped.. not a reboot fix type drop, just won't come back drop..

Ok, So far I've been loving this phone, no hiccups, no reboots, no problems and loving the battery life.
I live in a 3G only area so I have the phone set to CDMA only all the time. Last night I was having a chat on Google Talk and my 3G dropped, I figured, meh, it's just gonna need a reboot or let it sit for a while to come back. Well it sure didn't.. that was 12 hours ago from posting this. I've tried every toggle known to man, reboots, etc.. Nothing will give me my 3G back. Can someone please help me to prevent from having to call Verizon and go through all the reboot your phone, return to factory settings crap. Then end up with a factory like-new phone when my phone isn't even a month old yet. Wifi is working fine here at work, but I need my 3G.

Mine is screwed today as well... If it takes a factory data reset, I'd just as soon do it on my own. Update to fix isn't due until November... Grrrrrrrrrrrrrrrr...
Anyone with any real solutions? All the reboots/battery pulls/airplane mode toggles have been performed.
Thanks!

If both of you are experiencing issues today it may be something as simple as a network issue.

I thought so, but other people with smartphones around here on verizon aren't experiencing any issues. So I've eliminated network issues as the problem here.

yeah i think must be a network issue

Yep, same here... I even have a guy in another department in the plant with a Bionic and his is working just fine while mine sits brainless. it's definitely not a network issue for mine. aCk!!!

A new SIM card later... DoH

I have been dropping data connections also and it takes awhile to come back on sometimes. Usually if swith from 3g to 4g and such it comes back but I am getting frustrated with it. Other than that I love it.

Yeah, I'm really getting sick of the dropped 3G too, I can't figure out a pattern to it either, just drops out of nowhere sometimes.

I am having the exact same issues......I have power cycled, done battery pull, etc. Does not seem to be a network issue as 3G can be working fine one minute, not working the next, then go back to working again 5 minutes later. The duration almost seems random in nature. Very frustrating. Other than that I love the phone.

Same as pretty much everyone else. Really intermittent data connection problems. Have gone through 3 handsets so far.

Isn't there a number that can be called that updates your phones tower info?
Just found it. Try dialing *228. Not sure if it does anything or not but I have been dropping 3g too. So far my signal is much stronger but time will tell.

I'm having the same problem, but only at work. The signal fluctuates almost constantly from 4g to 3g with 4bars, to no data connection. Outside I get a stable 4g connection. My T-Mobile phone had a stable but weak signal here.

I thought *228 doesn't work on LTE phones? Mine won't even make the call when I try it.

It doesn't look like its dialing out. However, I am getting a message that my verizion sim card has been updated. So far I have not lost service in places where I would frequently lose 3g. Could be a placebo effect though.

Alright guys here I go I should of posted this on a topic thread I started couple of weeks ago but whatever here it goes and i hope it helps... So I went through 2 hard resets and one new SIM and so far this is he only thing the worked. Called big red and got a level 2? Tech support and since then have had no problems going on couple weeks now... Didn't see anyone mention this in previous posts. go into settings> Battery and data management > make sure you have "background data" and "data enabled" both checked. Hope this helps has for me and i hope I'm not repeating this info

Did the hard resets and sim change do anything? I have looked at my data settings and both items you mentioned are enabled on my phone.

Well yes on the hard resets and questionable on Sim card but data was still lost Week.later again and this new trick has been working since I did the changes going on about 2 Weeks now

Mine dropped today, one week into using this phone. Could be a fluke, but here's what worked: toggled LTE back on (no 4g here), then rebooted. Viola! 3g immediately. I really hope this isn't a constant problem...

Bionic 3g/4g is not working (DROP) "FIX"
After searching around a few days for solution n test many apk and many many methods... Finally found the fix.
Just download "BionicTCP" from market (Play Store) (REQUIRES ROOT), and click on "Large TCP Buffers". It makes my Bionic xt875 3G/4G NO DROP AT ALL.

[Q] Worth buying Droid 4 as GSM phone?

I thinking about buying D4 as my prime phone. I already find out that It supports GSM and how to unlock this feature. But is it worth to buy this phone to work on GSM? I noticed that there are many issues with it:
- not working callout on 3G on Android 2.3
- Verizon lockscreen that wants to activate phone
- problems with APNs
etc.

Yes! It's definately worth it!
The 3g callout problem is a temporarily thing, I'm sure of it. We're still playing with settings and drivers to fix that. In the mean time I use my phone on 2g for voice and 3g for iinternet. With one press of a button I can switch between 2g and 3g (There's an app for that )
The verizon lock screen pops up only once. Once you skip it, it doesn't return until you reset your phone to factory defaults.
Problems with apn's? Depends on your provider. I didn't have any problems at all.My apn settings were transferred automatically to my D4 when my provider detected that I was using a new phone. Even after installing different roms.
I'm using my D4 a couple of weeks and everything still works like a charm.

Mainly I work on 2G because of battery saving (it last for much longer!). But bug with callout has been patch in leaked ICS and what I heard it don't have Verizon stuff installed. I can't wait that some CFW ICS would use its libraries and kernel.
Unfortunately for now I can't afford on buying it because last 10 days jump over 10% according to my currency so it, when previously it had very good price then now it isn't.

I love it. I'm in Canada on Bell Mobility and everything works perfectly on Gingerbread, including outgoing calls on 3G. I think the voice issue is only affecting those within the USA on other carriers such as AT&T.

Whats the difference in using 2G or 3G for voice calls?
Isn't it the same?
Also, I wanted to use this phone on AT&T in the US. I just have voice and texting. Will this phone work for me?

Hi there,
did you have the chance of direct comparison to the Droid 3's signal quality, 3g speeds and call quality? I may consider importing it, but still not sure.
THANKS

It seems to work just as well as my Droid 3 did. The only issue I have is that the Droid 4 seems to underreport the signal it is receiving in the status indicator, the highest signal I've been able to see is 3/5 bars but it still seems to perform as if it were at 5/5.
I'm sure it is just tampering by Verizon and doesn't hinder the device's operation at all. I haven't tried any of the AOKP ROMs yet but will report back once I get a chance to install one.

Thanks for the reply!
Thats interesting, it's like the Droid 3 cheating on us that the GSM Signal would be very poor. Would you please have a look in the build.prop if there is a value ro.mot.phonemode.vzwglobalphone and set it to 0? Then prove if the signal gets better?

Interestingly enough, in the ICS build just leaked that has global support enabled by default, that value is set to 0 in the build.prop.
I am in the US and a VZW user, so I can't test the GSM radio performance on the D4 because they have disabled it for US carriers via another band lock or other mechanism.
I have been dumping and comparing the NVM of the various builds to try and isolate any critical differences to find the key. It may not, in fact, be in the NVM at all, but elsewhere in the radio image.
Just an FYI.

There is difference in voice codec (on 3G you should get better quality, but it also depends on the second side). Also at 3G you can use front cam for video conferences.

Yeah, the first thing I did once I could was look at the build.prop settings but I noticed that ro.mot.phonemode.vzwglobalphone is already set to 0, with a note in the comments above it that "the definition moved to cdma_maserati.mk to support different config for factory", which suggests that maybe their tampering is a little more hard-coded into the Blur interface.

No APN specified on the device - Driving me insane!!!

So yesterday I rebooted my phone and this popup keeps showing up saying 'No APN specified on the device'. I haven't changed anything, the old APNs are still there. Tried deleting and reentering APN but the popup still persists and now even my internet does not seem to work. To add to the trouble, the phone gets all laggy and jittery when this happens. However, once I connect it to a WiFi network, the popup goes away and the phone works fine once again.
Theres no problem with the network as my other phone seems to be working just fine, internet et al. Someone please tell me theres a solution to this :crying:

Which carrier are you with? You could try a SCRTN by dialing *#*#72786#*#* on the stock dialer if on sprint. That will reset the radio and the phone and force a reboot to do hands free activation again. Alternatively you could try to do a profile update through the settings menu. Though that then becomes more carrier specific as well.

Try a new SIM card?

[Q] Sprint G Flex loses service

Has anyone else experience complete signal lost in about every 15-20 min? Ive attempted a factory reset also a ##UPDATE# .

Goto settings->more...->mobile networks
Change it from Global to LTE/CDMA (if in Sprint variant) and reboot
I had the same issue as it will disconnect to search for a global GSM network to connect to every few mins and then reconnect to back to its home network when in global mode.

I live in LA and I get fast Spark speeds @ 30.00 Mbps on average. But what I notice is when I drive in my car or go to neighboring cities it constantly drops from LTE to 3G and the internet would be intermittent until I become stationary and would go back to LTE.
I will try lostsoul77 advice and report back to you tonight.
But yes, every 10-15 minutes it switches between 3G and LTE,

I attempted to change the settings to no avail. I've come to the conclusion that it may be a defective device and will be swapping out for a new one.

Did you reboot after you changed the settings. Try changing the setting, then update profile and prl and reboot
Sent from my LG-LS995 using xda app-developers app

I actually tried that as well! By the way I did end up exchanging for another unit. And unfortunately im still having this issue! Ive attempted update profile, update prl, ##update# , factory resets, settings mobile networks to LTE/CDMA instead of Global, and even manual programming using the MSL code. Maybe its something with the Sprint variant G Flex? Ive contacted LG and they want me to send my unit in for diagnose and repair.

I've had the same issues, here's what I've discovered.. Alot of us don't have band 26 and 41 up yet. And it's sprint wide.. Looks like the next firmware update will have the problem solved.
