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.

4G Data issues

Hello guys,
So I just bought my HTC one about a week ago. I'm.. pretty much in love with it. I haven't had time to sit down and room and customize it and such, but plan to soon.
However, i'm having an issue with it. The phone shows that it is connected to 4G and has full signal. However, it will not load anything whatsoever. Sometimes it works... but most of the time it does not, and I cannot figure out why. I also really hate that I can't manually toggle JUST the 4G on/off without diving into the settings. Waiting for the phone to decide to search for a 4G signal is frustrating. I'm somewhere I know has 4G signal, but the phone takes a long time before it realizes.
Is there anyone else who has these issues or someone who knows what I can do about them?
Thanks

I've actually been having that issue for a week or so. No matter what ROM I'm running. Very strange. Maybe Sprint is "upgrading" their towers....lol. I'm in VA, are you in VA by chance?

Maybe someone can answer this better but 4G doesn't have "bars" the bars are for your 3G do you may show full bars but still have a weak 4G signal.
The best way I have found to address this is if your connected to 4G and you aren't able to connect to anything go into your mobile data settings and temporarily switch to CDMA only, or toggle CDMA then switch back to CDMA/LTE this will cause your signal to cycle and you may be able to browse using the 4G.

Datdude, no i am in Texas.
Konfuzion, thats disappointing. Toggling the signals through the settings is really clunky and always ends up with my phone having no signal at all for a couple minutes while it cycles everything. Is there an easier way? Maybe a widget I can get somewhere to do it more quickly?
Also, I dislike that I have no representation of how strong a 4g signal I have. I don't want the phone to tell me I have signal where there is none. Is there a ROM that will show this, maybe?
All in all, while I love the phone, I'm beginning to regret the upgrade. 4g data is very important to me as I use my phone as a mobile modem for work. In places (the exact same chairs) where I had strong enough WiMax 4g signal to do what I wanted, even to play latency restricted games like a MOBA, I can't get the LTE to do anything. I really don't want to have to downgrade, just to keep access to an inferior 4g signal, even if it's more reliable.

Bump for help?

Check out SignalCheck Pro, it will show you your true 1x, 3g and LTE signal strength. I just got my One on Monday and haven't had any 4g issues here in NC.

You can also check your LTE reception by going to Settings->About->Network. Anything above -120dBm RSRP is useable, though if it gets much lower than that, the signal becomes tenuous. I think the lowest I've held onto was -124dBm.
Also, I run into this problem every few days around Chicago. The data connection just seems to stall. The fastest way I found to fix it is to toggle Airplane mode with the widget that I keep on my home screen.

Thanks guys for your responses! I went ahead and bout Signal Check Pro and although I don't understand all the numbers, my RSRP is around -105 to -110 at the moment, so it looks like i'm on the lower end of the connectively spectrum. Hopefully this app will help me better understand when my 4G is and isn't going to work.

Xperia Z1S (T-Mobile US) Issue

Hi there. Hope all of you are enjoying your Z1 as much as I am. I'm very pleased so far... well except for the locked bootloader and no root part. I honestly don't know what anyone is complaining about in regards to the screen. Sure the viewing angles aren't great, but it's not a tv. And the color accuracy is among the best I've seen.
That said there's a couple thing off the top of my head...
The notification bar changes from black to a dull grey when in dialer or settings. Maybe it did this all along and I just noticed but it's bugging the hell out of me. Anyone else experience this?
Also periodically at home I'll lose LTE. The icon will show 4G, but not LTE below it. Not a problem, but when I search the "Service Providers" in "Mobile Network Settings" I will find an LTE network, but there's a check mark next to the 3G T-Mobile network. If I select the LTE network it immediately connects to that. It makes me wonder if it would automatically switch over to LTE later (presumably on a stronger signal). Any thoughts?

I can only assume it is that there's a stronger HSPA+ signal than the LT signal. Can't comment on anything else - sorry. By the way, the Z was a locked bootloader, right? But, we found ways around that and for root?

Your base assumption is probably correct. I haven't seen this problem specifically, but the phone is probably being less aggressive about LTE where the signal is weaker to save battery.

No signal weird letters RSSI

Hey all,
So the issue is gone but still curious. I had no signal one day after class. All I saw was, no signal, even though my carrier logo was displayed. Tried loading internet but nothing.
Shortly after RSSI was displayed on the signal strength tile. I still couldn't place Phone calls or use the internet.
I'm suspect of my carrier AIO - AT&T having several mini outages and not telling customers based on previous situations so I'm investigating. Thanks for the help!!
Image is attached..

RSSI = received signal strength indicator.
Displaying the letters is a little strange though, sounds like a software glitch of some sort.

I have had exactly the same thing happen on my android mobile on kitkat in the last few days. I have noticed it on at least 3 occassions and it always seems to happen late at night when I have stopped using the mobile. It is very odd! I used Google to find the answer and it lead me here. Would love to know what it is and why it's happening.
BTW my phone is a moto g

my opinion; RSSI is displayed because you dropped your carrier. being a GSM carrier, it's possible you tried connecting to someone else's faint signal but never authenticated. this is all speculation, but hypothetically possible.
in other words, as long as you re-authenticate to your carrier, it's a non-issue.

Very strange, but I have a signal when it is happening to my phone and it is happening a lot lately, especially in the evening and then quite often as soon as I spot it it disappears. Starting to make me think something odd is going on.

well.. your image also shows "emergency calls only" which supports the theory that you've dropped carrier signal altogether. I believe you're right that believing that it has to do with the ATT/AIO service outtage.
but why RSSI instead of any other message... is another question altogether...

I do think it is a software glitch but it's very inconsistent. I feel strongly it's a Moto X or maybe Motorola firmware thing. With AIO I kept losing signal, so I left them and with T-mo now I and I experience the low signal rarely, and low signal here and there.
EDIT: I also still have some MMS issues w/ T-mo & AIO. not working, also inconsistent which I think is another firmware bug. Any of you guys have some clever ideas on how to troubleshoot this? Where would you start?
I'm rooted with R/W access and willing to dig thru system's files! apk's, whatever! Because this def is a problem and I would like to solve it.

I would also mess around with manual network selection while I had AIO so that could explain the weird signal stuff, here's the app I used in addition.

Strangely enough I've got this showing up in Airplane Mode on my Moto G as well (Verizon Prepaid activated but never paid for service). Also one night at random I noticed I had 3G showing up instead of just bars and used 250mb of data for free which was weird.

Try to specify carrier
Hey,
Please try to specify which carrier you prefer so your Moto X will not try to connect to alternative carrier with stronger signal.
