For me, a similar problem
Setting the network mode to auto or just wdcma makes the phone unusable.
Although the extent of the phone grabs. Nay, sometimes even 5 bars but the state does not tra large than 5 (sometimes 10) minutes and reach lost. Often with good coverage, I can not make calls and the internet does not work. Redials the phone ends in the subscriber information out of reach (the phone shows that he has range)
Switching the phone on GSM ONLY mode causes that everything starts to work as it should (only the net so slow)
The problem started a week ago
The problem occurs in various parts of the city, regardless of whether I use the transmitter Play network or roaming.
Factory reset did not help. I suspect the SIM card but the more I'm bending your point defect (eg antenna) since the last few months everything worked
EDIT:
1h watched by telephone yesterday, and what I noticed.
The problem is when a weak signal mode UMTS.
The signal strength of -90,-95dBm causes the phone to have problems. If the signal is below-100dBm the phone is able to maintain a dial-up connection to the Internet are no longer problems. Often there are also decreases above 100dBm signal which usually end up losing the connection of both GSM as well as internet and phone needs a few dozen seconds to reconnect.
If you set the mode to GSM only signal strength is-55dBm and the problems do not occur.

it's your network providers problem not our's. you can obviously not get 3G all around your city

After having my Galaxy Nexus for a few weeks I'd like to share my experiences with 'possible' data connectivity issues.
Firstly,
Upon first activating my phone at an official Verizon store I noticed that I lost data and voice services for almost 20 minutes after the phone was first activated. Toggling of 3G/4G, Airplane mode, and even rebooting (battery pull) would not fix the problem... It eventually just started working and has been fairly reliable ever since.
On the second day of owning the phone I unlocked / rooted... Still using the stock rom, antenna, and kernel though.
Secondly,
I've started to notice that every time I switch data sources.... For instance
*Turning off Wifi when connected to an AP
*Turning off 4G services
I'll completely lose data connectivity for a period of seconds; no longer than a minute (all gray reception bars). However, I can still make calls and send texts. My question is, is this behavior normal for the device? I've never owned a 4G device before so I'm ignorant to the matter. I'm simply inquiring as if this is a sign of a faulty antenna VZW is going to owe me a brand new device (not some refurbished crap either...). If this is typical, then I suppose it's just the nature of the beast. Either way, I've love to hear from others regarding their experiences.... Thanks!
Regards,
-Doug
When I had the thunderbolt data would drop in and out when switching from 3/4G and from wifi.
when you are switching from wifi to 4g/3g, it has to change your IP address, as its a different network. 4g to 3g viceversa it has to switch what frequency it is talking on, and reestablish communication with your carrier. switching data source will always drop data during the switch.
some later software upgrades have, and will reduce the time between switches, but there will always be some form of drop
Hi,
Using GNex, stock JB 4.11, Wind Mobile Canada, $40 plan, unlimited data & Canada wide.
Please excuse in advance for the novice questions. I am not yet familiar with Wind Mobile. The customer support is too long and submitting a question to their website required around 5 days to get an answer which is generally irrelevant in my short experience. Hope some expert users here can share some of your knowledge.
Last week, suddenly during a phone conversation, the phone became totally disconnected voice & data. The next morning, the situation didn't improve, so I rebooted the phone (power off / on). Then the phone could connect to voice, but no data (gray icon instead of blue). I stayed with no data for 3 days. During that time, I tried a few reboots, changing various network settings (APN, Network Operators, Data roaming, etc.). None of that worked, then I made another reboot and suddenly everything is back to normal (no roaming and data OK).
Q1. Signal strength variation: what is the cause that makes a signal vary? For the same location, sometimes signal changes from 3 bars to 1 within a few minutes.
Q2. What caused a network to black out temporarily? That's what I got last week during the entire night. The reception icon is a black outline triangle (no voice, no data). I purposely disabled roaming, I admit a network could have some issues, but I have hard time to admit that a disruption could last 12 hours. May be the issue is my phone? It was not rebooted since 7 days.
Q3. How often should I reboot the phone? By reboot, I mean power off/on. I hope this is the correct term. Is it possible that a frequent reboot help the phone to be more responsive? I tend to think so because all the network issues I got were magically fixed by reboot.
Q4. Why would a reboot fix a data connection issue? In my case, a few reboots on day 1 didn't fix. Many network settings changes didn't reconnect data. Then finally another reboot on day 3 fixed data connection.
Thanks in advance for any help.
Welcome to the Nexus and its crap radio. Try turning off 4G, once I did that I never lost signal again. With 4G on I get disconnected from the network randomly throughout the day

How to turn off 4G? Wind Mobile operates on AWS network 1700/2100 MHz (UMTS band 4), and HSPA+ for data. I believe it is not 4G. On the phone Network Settings, there is only an option "Use only 2G Network" which is not a good option for me. If I enabled "Use only 2G Network" the phone shuts off data and changes to roaming mode.
just set ur nexus on airplane mode for a second..
then disable the airplane mode instantly..
u ll gain ur net working widout reboot... )

Oh wow, that's a cool tips.
I hope someone can answers my other questions, I like to understand the "how things works" side.

Any number of influences. A microwave, air ionization, temperature, humidity, output from the tower not consistant, and plus just the variations of the phone. Going by bars is a bad way to gauge anyways, it could have only dropped signal for a split second but it doesnt update the bars frequently so it would appear to be low signal longer than it could have actually been. Your phone works by line of sight, picture a tight wire from your phone to the tower, anything that crosses in that line reduces signal.

That actually is hard to answer, you would need to contact your provider to see if they have a log of an outage at that time before going into whether it was the phone or not.
Q3. How often should I reboot the phone? By reboot, I mean power off/on. I hope this is the correct term. Is it possible that a frequent reboot help the phone to be more responsive? I tend to think so because all the network issues I got were magically fixed by reboot.
Never unless things act funny. A reboot is usually healthy for operating systems (i know many do not). I personally don't intentionally reboot mine, it usually happens because I'm screwing with clock speeds
Q4. Why would a reboot fix a data connection issue? In my case, a few reboots on day 1 didn't fix. Many network settings changes didn't reconnect data. Then finally another reboot on day 3 fixed data connection.
Like any software there are chance of a 'glitch' where the modem and the driver have issues communicating. Toggling airplane mode off and then back on re-initializes this and in most cases fixes the communication problem. Rebooting will have the same effect. I would only worry if you are needing to do this often.

Hope this helps a little.
I would also contact your provider. They may have an issue with the tower you are connecting to.
Perfectly understood, appreciated very much your detailed answers. Can you please clarify below?

Makes sense. Indeed, when I said "For the same location, sometimes signal changes from 3 bars to 1 within a few minutes". Actually, I mean a room and I was walking/moving so may be the orientation of the phone explained why the reception was inconstant.
Regarding your answer above output from the tower not consistant. Is it possible that the tower reduces its signal strength when the number of users increases? Similar to users sharing a finite band width?
Yes, even orientation of the phone can have an affect, depends how the antenna is set up inside the phone, i havent seen it so i have no answer for that.
ya, as you move around you could have been what blocked the direct sight of the tower, signal passes through nonmetal objects but each time it does, it loses strength depending what it passes through
@OP I also have the same problem, I am also with Wind and had to do force reboot to make it reboot.

Flash the UGLC1 radio to your nexus. I'm with Wind as well and that radio gets me good service!
Hi. I've an HTC Desire, with Rooted Gingerbread (2.3.3) and the 32.56.00.32U_5.17.05.23 Radio. i'm in italy, under Wind, but i've also a Tim Simcard and both have the same problem: Under WCDMA/GSM or WCDMA only, sometimes the connection drop, maybe during a call, and then i'm not able to receive calls or sms'. most of the time the data connection works fine, except that sometimes it remains stuck and says it's uploading something (the icon on the notification bar) but after less than a minute it goes again. Please help me, i've tried different roms with different radios, when i first bought the phone (used from uk) i remember it worked fine, i started noticing the problem after i installed a gingerbread rom with sense 3. i can't use the GSM only mode, cause i've a data plan and i need browsing, so GSM is too slow
thanks

It may just happen in areas where you have poor signal.

thanks for the answer. i noticed that this situation is stronger in my bedroom, where i keep my pc. not in my house, just in my bedroom. the signal is not poor, i tried to download many app from the play store, and sometimes the download is fast, sometimes the download stops. then i tried the same thing out of my house, but connected with the same cell, and even if the signal was lower, and the download speed too, the download went good, and the signal never dropped, the connection type was WCDMA/GSM and the phone was in HSDPA. i don't know what it can be, i'm starting to think that there's something in my room with and electromagnetic field.

Maybe you have well-built house
Anyway, it's common problem. I have 3 Desires and they all loose connection in some areas for a while.
Every phone behave like that.
For me a useful trick was to change from GSM/(WCDMA preferred) to GSM/WCDMA auto as I'm hardly ever using 3G.
Phone chooses the strongest cell now, not just WCDMA cells.
I'm using CM7.2 and in CM forum there is a lot of issues considering 3G stability in Desire, so not much can be done.:crying:
Cheers
I was originally a Verizon user so I'm not used to this kind of weak connection.
I had my phone replaced already due to another issue a few weeks ago
so I don't want to get another replacement because of this. it is really annoying!
Instead I will ask here and see if anyone could help !
**This has nothing to do with WiFi (because WiFi works great!)**
**And nothing to do with calls because call quality and connection showed no problems**
**Not exactly sure this problem started, just started getting annoyed with it recently**
\- What my phone is doing (when I'm at home) -/
1. Slow transition from WiFi connection
- When I turn Wifi off, I don't get an immediate data reception. Instead it takes about 10 seconds and then I barely start to get 3g..... not lte .... (It's not like this in every place)
2. Not much LTE
- It happens really rarely, most of the time at home the connection is on 3g
3. Lose data connection even while in use
- It's just sometimes unstable. When I'm browsing the web (while in 3g) it would sometimes go down to no bars at all and lose internet connectivity, then the 3g and I have to wait again until it comes back.
- Data roaming automatically turns on saying that I lost connection -_-
4. 3g is sometimes really unresponsive
- Just like when it is when turning off Wifi
- 3g would stay idle for sometime, even when I open apps that require internet
- Sometimes the 3g just disappears and decides not to comeback for a while
5. Bars up and down (drains battery?)
- I see this too often, like in every hour. While in 3g, the bars get suddenly full, then in an instant it drops to 1, then to 2. Then sometimes to no bars at all.
* in LTE it never gets like this, just constantly 1 bar
6. Maybe it's where I live?
- Possibly, but it's quite an urban and Sprint should have no problem covering this area in my opinion
- Verizon wasn't like this (although not perfect)
7. This is annoying
-Because it is draining the battery -_-
-Because my sister's iPhone 6 performs better (always has 2~3 bars) & my brother's S6 (though relatively weaker than her's) does not seem to lose connection compared mine at home (We're all Sprint users)
\- What I've done to confront this problem -/
1) Called Sprint, but didn't help at all. They told me to just take it to the store and have them take a look -__- Agent hardly knew anything...
2) Flashed Stock ROM and hard reset the phone (so annoying since you have to set things up again)
3) Made sure I set mobile data Network Mode to 'AUTOMATIC'
4) Made sure I have the latest Software version and have the PRL and Profile updated
But still no result at this point.
***Could this be a hardware issue? Or a software issue that is fixable?***
Can anyone give me some advice on how to fix this?
I mean it's just that the data reception is too weak an unreliable to think this is okay.
Right now my phone is pretty empty, barely any apps because of the reset.
I really don't want to believe it's due to a faulty hardware!
P.S. Possibly symptom?
The first day I got this phone as a replacement out of the store, I was unable to connect to the internet using data, even though calling was working.
What it was doing was, constantly switching from 3g - lte - inactive 3g - nothing - 3g - so on in a 20 second cycle.
By the end of that day towards midnight it was connecting to the internet.
Welcome to Sprint -_____- my GF has 4G LTE on Verizon where I live and I don't even have 3G, I roam on Verizon actually lol. Sprint literally has ZERO coverage while Verizon has LTE.. It's just Sprint dude lol.
I just changed my SIM Card from a 3G SIM to a 4G SIM recently. However I met an issue, whenever I use the 4G Mobile Network for too long (like 1-2 hours), the phone will suddenly lost all signal for 5-10 minute before recovering the signal. The signal bar is empty, and it appears the "Emergency Call Only" stuff. Is it just me or everyone is encountering this problem?
I have no problem at all when restrict the phone to connect 3G/H+ network only, it only occurs when I connect to the 4G network for a period of time.
My friend that uses the same telco with me doesn't have such problem (disconnecting/no signal at all) when connecting to 4G network, and it doesn't seems to be the antenna problem since the problem does not happen when I connect to 3G/H+ networks.
What might likely be the cause? Is there any solution to this?
Sorry for bad English, not my native language
(I live in Malaysia, and using UMobile Telco. )
Now that you mention it, I have pretty much the same issue of losing signals, and the problem hasn't occurred ever since I stopped using 4g. I didn't notice it was because of that, because I changed the phone too while changing the sim. I have marshmallow by the way. Don't know if that might be linked to the problem.
