Frequent loss of data - Nexus 4 Q&A, Help & Troubleshooting

Hi I have a problem with the data, it is often as if he lost the connection to the mobile network internet shutting down for a few seconds and then reconnecting after a while. The whasap not send, do not load the pages ... I have to remove and replace the data.
Does anyone know why is this happening?
thanks

What is your APN settings? I had my APN protocol and APN roaming protocol set to IPv4/IPv6 and was having the same issue. I switched it to IPv4 only and haven't had an issue since.

Edit: Nevermind...

It's a software problem which will hopefully get fixed in 4.2.2 update

I found a little trick. by keying in *#*#4636#*#*
in phone information on the option to change the network type, I replaced wcdma preferred for LTE/GSM/CDMA auto (PRL) and the problem is gone.
Served to me to, I hope you do too

I did that trick, but after rebooting the phone, setting reverts to the original one, "WCDMA preferred". Is there any way to force that setting to be permanently saved?

Restarting the phone is restored to as before, no rebooting.
Is a solution a little bad, but at the moment there is nothing better

[Q] No data connection when switching between gsm and wcdma

Hello!
I'm using Rafdroid HD von my HD2 now for 2 weeks and I'm verry happy with it, i just have one problem (dont know if it depends on de android build or on the hd2 or whatever...)
I'm using gsm all the time because it has less battery drain in stand by, but when i want to use data for surfing etc. i switch to wcdma. on my x8 wich i had before this was no problem, it switched within seconds between the networks. Also the HD2, BUT it doenst start a data connection. i just can talk but no data.
in "wireless and network" the option for wireless data is checked, but the whole option is not clickable and it says "starting" (dont know if it says starting, i use the german version, there it say "einschalten..."
when i restart the hd2 then the data connection is working. so all times when i want to switch the data connection i need to restart my hd2.
is there a way to solve this problem?
sorry, i've searched the forum, but i haven't found anything
thanks and best regards, chris
No one who knows something about this issue?
tried this yet??
enter: *#*#4636#*#* in your dialer
go to phone info
go all the way down
now you can manually switch between edge or 3G
(default should be WCDMA preferred)
Thank you, I've foudn this idea before but it doenst change anything.
I'm using the whole day only gsm/edge, but when i need more data (searching something on google etc.) i would like to switch to 3g. after this, back to wcdma. on my x8 this worked well, on the hd2 it looks like it cant start the data connection when switching between the two types of network...

Problem with Koodo network

Hi all, got a really weird problem with Koodo.
I got a new Micro SIM for it today, and it didn't pick up the network so I asked the people at Koodo kiosk to test it and it worked fine on another phone so SIM, or network shouldn't be a problem.
After some fiddling around, I changed the network type in the Testing menu(by dialing #*#*4636*#*#) to WCDMA Preferred (later found that CDMA/GSM Auto (PRL) and WCDMA Only and Unknown) gives me signal and I can make calls, but the default CDMA Auto (PRL) doesn't work.
However, whenever I make a call, there's a little text popup at the bottom that says "Sending", and after call completes, the Phone app crashes and it seems to go back to the normal settings (CDMA Auto)...
So it's a really weird problem... anyone have any insights to solve this?
To add: I did try Rogers SIM in it before, and made some changes to APN and changed the network to LTE/GSM Auto for testing, not sure if that could be interfering with it now because it's using the default APNs.
Another edit: I think reason Phone app crashes is because it's the Testing app where you select network type that crashes. If I exit out of that before making the call it doens't crash.
Are you by any chance using the lte toggle in aokp? I remember when using that it crashed the phone app, which aokp build are you on?
The phone should default on WCDMA Preferred, and if you have lte use lte/gsm auto.

Yeah I do have the LTE toggle in AOKP, but I think the crashing was due to having the testing app open.
Anyways, it seems to default to WCDMA Preferred now... dunno why it wasn't on that before, because I rebooted many times and it always no signal. It seems to be all good now, no crashing and signal's strong.
If you used the lte toggle in aokp it would defaul to cdma, then after a phone call the phone app would crash, the only way to solve that would be to wipe the phone, been there done that.

Mine is back to defaulting to WCDMA Preferred... Is it because I set it to that manually?

Yes, if you use the lte toggle it'll default to something else since the lte toggle wasn't made for the nexus4.
Glad to see you appear to have made progress here? Apologies if it was AOKP related issue and not straight forward apn as it sounded in kernel thread.
May be with warning others back in ROM thread once resolved and if you're 100% sure toggle was cause?

[Q] Mobile Data not working

Hello all,
I have resorted to posting here as i have trawled the web for a solution without any luck. Here is my problem hope you can help.
I have a nexus 4 and am currently in Spain. After traveling abroad and not using data roaming i came back to Spain to no mobile data connection. The usual tricks of restarting, toggling mobile data airplane mode didn't work. It was quite frustrating. I went as far as to cancel my contract and go for a prepaid card - Lebara as they have a decent data tariff - but the problem persisted. I have configured the APN, gone through all the restart procedures, even factory reset the phone twice and nothing helped.
Mobile data is switched on. I have the APN set up as needed. However, the H E H+ never appear next to the bars on top no matter what i do. I have ordered another SIM card from a different operator in desperation but it might not be here for another week.
I really hope it is not the phone but now I really don't know. I am taking suggestions...
Thanks
PS one thing I just noticed is that if I download apps from my browser the device is listed as vodafone nexus 4 although I have never been on vodafone. This might have some relevance

Go to the dialer, press*#*#4636#*#* this brings you into new menu. go to the phone information to see to what network you are connected. if you scroll down you can force the phone to use 3g (WCDMA only) see if this work. this seting will change when the phone goes into reboot.
also if you happen to have the "3g bug" connecting to a wlan might help as stated by some users.
For me starting the hot spot function does the trick.

Thanks for the advice endet. I have done this but to no avail. When I switch to WCDMA only in the field GPRS service it says connecting for about a minute and then disconnected. After restart it is directly disconnected. I have toggled between GSM only and WCDMA only and restarted the radio. Played with the other settings in this screen and nothing. Only once did I get brief flash of the H on top but trying to replicate the steps didn't lead to anything.
Starting tethering didn't help either...
Could be something with my IMEI? Or CellInfoListRate?

[Q] SM-G900i with ATT network

I got an international version SM-G900i from Amazon. I have an ATT sim card. The text and phone calls work fine but I could not get any data roaming. Though from other posts I got the data roaming, I was not able to set onto the ATT 3G/2G network in the network operator selection. My network is always shown as Maritime. Does anybody know why this happens and ways to change it?
Thanks a lot.

Have you checked apn setting and made sure they are correct for ATT?

I tried configure the APN setting based on a link online for ATT APN. Now I am losing signals even for calls and texts....I think there might be other things that are wrong...
Error message for no ATT service
Tried different variety of ATT APN setting. Still could not get it to work....the phone shows a signal but gave me an error message that Selected network(AT&T) not available

I'm not sure what did you mean by "data roaming"??
Anyway, the problem for now is no network register. The APN settings will NOT affect at this step, so not not try to mess up with it right now.
Try to get into Settings > More networks > Mobile networks, and set Network mode to Auto connect, and Network operator > Select automatically.
That may help the device to register on the Home network.
Problem solved....or maybe not but it is working!

Okay. Thanks. I switched it back to the auto-selection mode. By data roaming....I mean 3G data. My phone is working now. I checked ATT billing usage report, it did not increase the data usage dramatically so I guess everything is fine.

Glad that your phone works now.
BTW "data roaming" and "3G data" are different things. "data roaming" is "3G data" when you are roaming to another network (not your home network).

APN Settings Missing (Stock ROM, Unrooted)

I recently rebooted my phone. Once it came back up, I was unable to connect to my cell network (T-Mobile). I have found the APN setting is missing (Image 1). Using the *#*#4636#*#* and selecting Phone Information (Images 2 & 3) I don't see the phone's IMEI, the GMS Radio shows as OFF and selecting the "Turn Radio On" does nothing. I've tried to change the "Set Preferred Network Type" to LTE/GSM auto (PRL), or anything else for that matter, and after rebooting it is back to LTE/GSM/CDMA auto (PRL). Factory resets haven't worked, with and with out auto restore enabled, even not signing in with my Gmail Account. Removing the SIM and reinstalling does nothing.
Thoughts? Is the GMS Radio fried?
Maybe bad Sim. I have had 3 changed. I was told this phone should stay on cdma, gsm, LTE auto prl. In hidden menu. And global in network settings in android. Have not had a problem since. Fingers crossed.....
