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.

Radio switch

Has anyone out thought of a switch for root users on 4g phones to disable 3g so you don't have 2 wireless radios for 3g and 4g running at the same time? If so, can someone name the app, or tell me where I can find the info on it?
Sent from DB using XDA

I think if you disable the 3g radio you would have no voice or text. Someone correct me if I'm wrong.

you're right. 4g is only for data.
Sent from my DROID BIONIC using Tapatalk

I'm not sure this is correct. On the Thunderbolt, you can switch it to LTE only, and it remains able to make calls and send/receive texts. Although perhaps that doesn't disable the 3G radio.

Only reason this even came to my attention is because I had heard rumors about the Sprint users being able to disable their 3g radio and still receive texts and voicemails... So, I figured I would ask about it. I mean with dumbphones that weren't 3g how did those receive those functions without a 3g radio?

voice/text messages are on 1x while internet is on 3g/4g

Issue I see, is sometimes I'll lose 4g around here (GR area too), and if 3g was off, I wouldn't have data at all.

Than why when I'm on 3g, in a non 4g zone, when I go to make a call, the phone disables 3g?

Radio Switch
@sheatyj - I would have use for this though because I travel the country for work... Most places I go are all 4g (or at least Verizon claims them to be) so if I can disable my 3g radio, I can make my phone last a little longer... Also It will help with me having issues with my phone jumping back into 3g when I just had 3 bars of 4g.

heard of a toggle on thunderbolt a widget

How about switch to turn off all but wifi?
A nice feature of my Blackberry was the ability to turn OFF the telephone and leave the WIFI turned ON. This was great for non-coverage areas and when I traveled internationally. Can this be done on the Bionic? tnx

Just enable Airplane Mode. That will turn everything off.
Once everything is off, just re-enable WiFi and/or Bluetooth if you want to use just that.

[Q] 3G networks not detected on 4.4.4 update

I have updated from .230 firmware to .283 via Ota and root is preserved but after the update my phonr cannot detect 3g networks. Before it was fine. Does this happened to any one else?

Can't detect or detects but doesn't connect?
Check the APN list, you might need to select / reselect / add APN.

It doesn't detect any 3g network at all 2g is fine and I am in area where multiple 3g networks are available. BTW I am from India and in .230 firmware it was all fine.

Like genieass said It might be network related. I only offer a suggestion.
Did you try Settings > Wireless and Networks > Tap "More" > Internet Settings? Just tap it and wait a few seconds

The phone cannot detect 3g networks. 2g is fine 2g data is fine. But when I switch to wcdma or GSM/wcdma on network mode it cannot detect 3g networks at all. It just shows no network even though 3g is available. Trying manual searching for 3g networks is also showing no 3g networks.

I am speaking of data. If you are talking about proper 3g, I might have misled you. You seem to be looking for 3g calls etc? if so, pl ignore me.
My connection is 2g, data is 3g. I am on H+ most times. Firmware updates are faster OTA, 3G than wifi. Which connects thru a 512 mbps dataone adsl line.

The phone simply cannot detect 3g networks. The data part and Internet settings comes after the phone detects 3g networks. So no its cannot be done. When I am on wcdma only setting the phone doesn't show network ie I am on emergency mode. If I try manual searching of networks it doesnot show any 3g network even though I am in a coverage area with multiple 3g networks.

Open up dialpad and type in " *#*#4636#*#* ". Inside "phone settings" you might be able to adjust to some options which might work.
Restart your phone and confirm that the modification has been lost.
Unfortunately it is reset every bootup. So you might want to fallback to 4.4.2 (hack, or 4.3) and wait for solution from Sony.
Post the result of this to Sony Mobile Official Forum might help. Anyways, please report back after trying each option.:good:

After my update to 4.4.4, I lost the ability to access the Internet over my mobile network. I had full signal and even hdpda/hspda+ sometimes but no Internet at all. I realize its not the exact same issue but they might be related. I found out that my APN had been changed when I updated, so I hit settings>more>Internet settings and it fixed the problem. It didnt need to be connected to the Internet to do it either, it just worked on the same network connection that wasnt giving Internet. Hopefully this works for you too, since this caused me endless headaches when it happened.

Yeah but for me no signal when in WCDMA mode just shows emergency mode but when i switch to gsm mode it shows full signal. My APN are automatically downloaded every time i insert my sim card in the phone so APNs are fine asthey are auto downloaded on 2g. But no 3g signal even in full signal strength area. Seems like I have to do repair by PCC which i am trying to avoid as my internet connection is slow. I'll post if the repair is helpful. I was just trying to know if anyone else have the same problem or not.

If all suggestions here failed, then I am quite certain that either your network provider has a problem or your phone has a FW issue. Provided that you dd not fall the phone carelessly and damaged the modem, i would recommend you go search on google for this issue with your network provider on the search keywords. If no luck, Just downgrade to 4.4.2, then report to Sony as a bug.
Anyways, Good Luck

[Q] Verizon Network Extender Issues

Anyone else with a Nexus 6 on Verizon using a network extender? It works fine for voice. However, I cannot get a data connection through the extender. I assume its an APN issue. All other Verizon phones are getting data fine through the extender.
Ideas?
Thanks!

I don't think mine is connecting at all to the extender at work. There is no icon change.

It works for voice. I get the beeping before a call. But it is not utilizing the extender for data. Its killing me because I'm in a fringe area for coverage and its killing my battery.

I'm running cm12 and whenever I connect to a network extender I loose LTE after I connect back to the network directly. I have to backup, flash stock ROM, let the phone activate then restore my twrp backup. Major PITA...

Sorry for resurrecting this thread, but has anyone found any resolutions to this issue?
I'm right at the edge of 3 towers, without my extender, I can barely text... Don't get me started on MMS... I will often miss calls also.
According to the Network Signal Info app, I'm always connected to the extender, but I get very weak signal. I rarely get 3G, if I do, it's even more rare for me to get data despite it showing 3G.
Usually it's 1x that eventually connects where I get data.
Sure, I can use WiFi, but text and especially MMS are issues. Who knows if I'm missing calls also...
Hopefully the Verizon firmware/radio files will work better when Verizon eventually releases it?

Try setting your phone to 3g instead of lte. Should jump on the extender for data. On mine it won't switch automatically.

I did try that a few times, I haven't went too in depth with that. But if I recall correctly, changing that setting just left a "!" in the signal bars, no data. How's your signal strength on the extender?

It's half way up the triangle. Orange on the signal strength under battery. But it works.

That doesn't work for me. 3G is HSPA on the N6, not EvDo like the extender requires. My workaround is connecting at home via wifi, then switching data to 1X. That solves calling, data, and SMS/MMS issues.

From what I've read in other posts regarding Verizon extenders, they are only for basic text and calls, NOT Data. Call Verizon support to confirm if you want a definite answer though.

Not true. It does data fine at both 1x and EvDo 3g. As I said, problem is, the N6 doesn't appear to work with 3g EvDo data.

Correct. I've had my extender since 2011. Without data, MMS as well as certain other Verizon features would not function.

I just flashed the Android 5.1 radio on my 5.0.2 ROM running Chroma.
I can confirm that EV-DO Rev. A works now on the Verizon Network Extender.
When I have the network mode set to Global or LTE it keeps falling off 3G. I've set the network mode to 3G and it has stuck for a solid 30 minutes now.
Hopefully the stock 5.1 ROM will fix the 3G issue in LTE or Global modes, so it doesn't try to connect to the weak outside signals. But at least we get EV-DO now instead of just 1x!

hmm, thanks, no 3G option in my preferred network types on the stock rom.
I wonder if the network extenders actually validate the IMEI and that's why its not working. It worked on my old XT926.

I also have been fighting with this since getting my Nexus 6 last week...they say dial *48 and it will tell you if you are under extender coverage...which I am, yet a tier 4 tech tries to call me and it goes direct to vm.
I have changed units...still same....frustrated as heck.

I'm confused. If you have a network extender, you have Wi-Fi within the same range as the network extender. Why would you want to use 3G for data instead of Wi-Fi? Even the slowest Wi-Fi would be better than 3G data.

T-Mobile. Let the device sit overnight and it got LTE back. So it seems either the LTE radio in this device is terrible compared to my Note 3, or it just won't attempt to get back onto LTE all that often. Or my Devices LTE radio is messed up.

Telus Canada. XT1103.
Mine would stay on H+ after a call for a long time. I sometimes "force" it to connect to LTE by toggling cellular data and off in settings. Or a reboot.
Have tried the *#*#4636#*#* menu to change to "LTE only", but won't even connect to LTE in this case.
This feels like a software issue. Clearly it's not a network or hardware issue, since it can connect to LTE.

if its not connecting to lte when you set it to lte only, then you either dont have lte around when you set it or its an extremely weak signal.

Unfortunately, it depends a lot on where you are. The office building that I am in is very bad for LTE, signal at my desk is -100dbm, if I go outside it switches up to around -60 to -70dbm. If I choose 3G as the preferred network, sitting in exactly the same location the signal goes to -75dbm 19 au. If I am at my apartment, the LTE signal is much stronger there. This of course effects the battery life also. I am not sure if there is a way to default which LTE band is used since I think Telus only uses band 4 for LTE but I am not familiar with how the phone determines which band to use or if it keeps scanning all of them.

No, where I was testing it, LTE was strong. I also had a Nexus 5 right beside it, and it had no problem acquiring a full signal.
With the Nexus 6, after a reboot or the data toggle, it acquired LTE, again almost full signal.

So I decided to just leave it alone and use it as normal without worrying about LTE or H+. I did not toggle data or reboot, just leave it as is. I just observe. After a few days, it seems better in that it will be connect to LTE a short while after a call, and behaves like how I expected it to like on the Nexus 5.
Of course, immediately after a call, it will stay on H+. If I really wanted LTE right then, I just toggle the data on/off from settings (not by setting to "LTE only" in *#*#4636#*#* menu).
