Hey try to replicate the data issues, and then once data drops can you try to clear cache and app data for Google services framework? See if that brings back data/ keeps it active.

Please report back.

When you open you default apn, in APN type, does it say default? If so, just delete it and leave it blank, hit menu and save. Report back please.

I was able go get my device working using trial and error. as I mentioned long ago, old kernel seems to help. Then data dropped yesterday, clearing the app data in Google services frame work helped. No drops for over 24 hr period. Anyway I placed an RMA for unrelated issues. Will get new nexus on Monday see how that plays out for data on stock and after root.

AW: [LOOKING FOR A FIX] DATA drops

Got my motherboard changed nexus back. No drops so far. This evening I will restore my nandroid backup from the "old" phone
[Nexus 4 Q&A, Help & Troubleshooting] starfarer:
Rev:10

ROM: CM, currently maddoggin

Kernel: tried -cm default , faux incl modified stock, franco

Network: virgin UK

Location: London

Desc: at home I'm always in WiFi. Travel is underground and workplace involves moving into basements. Basically phone needs connecting back and forth. And at least for me, that's where the problem is - data is very erratic. Works fine for few mins maybe 10-30mins and then suddenly no internet access. The signal bar status remains in blue with H without up/down arrows and obviously no access to internet. Now if left the phone in this state for another 5-20 mins, everything works like normal until another 10-30 mins and the cycle repeats.

Changed ROM, kernel, empty APN, reboot, airplane mode etc and nothing works. ATM intersectraven's test kernel is showing promise. Been already 2 times from basement (no network) and data connection is holding strong. Still to test after WiFi.

In last 9 hours, I've been on phone browsing for close to 5 hrs :).
[Nexus 4 Q&A, Help & Troubleshooting] steviewevie:
Grey bars does not mean "no data". That just means that you are not connected to Google's servers. You can have grey bars but perfectly functioning data.
[Nexus 4 Q&A, Help & Troubleshooting] undercover:
Yes, but in our case it's a pretty good indicator that data is not connected.

I was getting data drops really bad with

It would show full signal but Facebook would be constantly loading and YouTube constantly buffering.

I have since flashed a beta version of AOKP sometime around jan13 I believe with the stock kernel that comes with it and all is good so far.

Not to mention I'm getting 14 hours use with 4-5 hours screen on time!!
[Nexus 4 Q&A, Help & Troubleshooting] JJustin:
I am getting the data drops too. Using paranoidandroid and intersectraven kernel on bell mobility Canada. Using apps that require data won't load or I'll have to close and reopen it.

[Nexus 4 Q&A, Help & Troubleshooting] kresk:
So after a while of testing I honestly think the issue is a carrier signal thing and the phone is just reacting to it. I still had a few falters with the settings you suggested (thanks nonetheless). After a while it was hard to tell if it was more or less than before. It just seems like when I'm in an area where my connection is slow (which is often indicated by the phones performance rather than the signal bars because they won't coincide with one another) anything can happen. In my house it's weird, but only in the kitchen and living room. In my bedroom it's always good. Same thing with certain parts of my city. When I'm in one of those iffy areas my signal is inconsistent. Maybe an update will be helpful.. I guess I'll just wait to see what comes of this and enjoy my lovely Nexus in the mean time.. Peace.

[Nexus 4 Q&A, Help & Troubleshooting] undercover:
I've got a feeling it could be due to us flashing certain kernel with a certain change. That probably buggered sim card. It happened to all of us at approximately same time. If it IS due to sim for most of us at least, then my theory stands I think.
[Nexus 4 Q&A, Help & Troubleshooting] 309041291a:
I'm on WIND and I also have a problem, although I'm not sure if it's the same data drops you guys are having.

With WIND my data only works when it says H or H+, when it says 3G the data will not function at all. The bars will stay blue and the the 3G icon will be there but data will not work. Until that is the H/H+ icon returns.

The problem is... When I stop 'using' the data the icon goes back to 3G. What I mean is if I'm scrolling down an internet page, streaming content, browsing XDA I will reach a certain point where I do not need to load content cause it's all fully loaded already (let's say you fully load a Google search page). The icon will turn to 3G then I have to wait for the icon to change back to H/H+ before it will load anything else.

So, it'll turn to 3G and make me wait for 10+ minutes sometimes forcing me to restart the app entirely only to face the 3G issue within minutes. It does this all the time, halfway into streaming or downloading (then it will just refuse to continue loading the content even after the H/H+), playing games (disconnects me online like Z4), etc...

I don't know what's up. I'm going to ask WIND soon but I doubt they'll know.

I get this "data drop", but it's more like data lag. And to note, I only started to experiencing this when I switched from Straight Talk Byop ATT to a prepaid Tmobile plan. ATT would data switch between hspa:10 to hspa:15 but consistent data. Where as on Tmobile it idles on utms:3, and switches to hspa:15, but almost always a delay, sometimes more than others.

Anyone try using an IP address instead of url in apn, if that makes a difference?

All of my recent Android phones have done this. Usually for me its no "H" or "3G" or "G" but signal bars are present (sometimes blue sometimes not).

cm10 and data drops

Hello,

I have a rev10 running cm10 with the stock kernel provided with the ROM. I am on AT&T and have an LTE data plan.

I have tried a few different APNs before I switched over to CM10 and was experiencing data drops and lags. Now that I am on CM10 there are a few AT&T APNs to choose from. I am trying the LTE APN and also the WAP Cingular APN. I am getting data drops and lags on both of them.

I have not tried another SIM and I have not tried another kernel. I guess those options are next.

Any other suggestions. A radio change maybe?

Really hoping 4.2.2 fixes some issues and comes with new radio.

I have been have issues with my nexus 4 here in Massachusetts with t mobile where i get "H" showing up on my signal but for no reason it switches to "E". The signal strength is good so i think it is just randomly dropping the data signal. The most annoying part of all of this is that my blackberry holds a solid 4g connection sitting right next to my n4, even with the same sim card. :confused:

[Nexus 4 Q&A, Help & Troubleshooting] phrami:
I sure hope 4.2.2 is going to help somewhat.

I have the exact same issue, as soon as I use any app that requires data connection it will disappear for a few seconds, long enough most of the time to have the app or page to time out. I am still on stock everything, hesitant to try anything so far.

I do use WIFI extensively, one thing I have noticed though, rebooting the phone every other day somehow helps,

I am on TMO in houston metro area. There are some dark spots on TMO network all around houston, I also tried the fast tmo (TMO LTE?) apn and did have some success with that.

I have seen posts elsewhere that a replacement device was required to fix the issue, anyone got a replacement device that completely eliminated this issue?

I blame TMO most of the time though not the phone, I had similar troubles (much worse) on my SGS4g as well.
[Nexus 4 Q&A, Help & Troubleshooting] lorin_93:
I've also been getting data drops on my Nexus 4, on giffgaff UK. I've fixed them by flashing codefirex SR11 ROM, faux123's kernel (last stable one) and by switching to LTE/GSM/CDMA auto (PRL) in Phone info (*#*#4636#*#*).

It seems to be working decent without the LTE/GSM/CDMA thing, but it's very slow and it seems quite laggy (enough laggy for facebook messenger to time-out). Switching to that from WCDMA drastically improves speed and responsiveness of the network. Mobile websites are loading within 1 second (feels almost like on wifi). I don't know if it's the combination between ROM, kernel and that setting for network or something else.

But I can say that I was getting serious drops on Montley kernel. On franco kernel, the mobile data was completely unusable (it was just staying on grey H, never switched to blue H/H+ or loaded anything).

Can someone confirm this?

seems to be fine now
[Nexus 4 Q&A, Help & Troubleshooting] eric_son:
Hahaha... same here.

:)

Previously in 4.2.1, once I lose data, I'd lose it for good. Even if I get to a place where I know there is a good 3G signal, the phone signal still indicates the gray triangle w/o the H. The only way for me to get it back was to either reboot or to toggle between plane-mode and phone-mode.

Now under 4.2.2, although I still lose data connections on the same areas (3g dead-zone perhaps?), my phone is now able to re-establish data quickly.

Anyway, looking good so far! (knock on wood...)

Hi everybody, *pfffff* finally got my N4 yesterday, after several months trying...

I have constant data drops. H+ and 3G shows with signal bars, but they don't turn blue. Nothing happens. I thought at first that it was due to bad signal @home, but I'm now in the library and can't use tethering properly (no wifi here) because of the constant data drops.

Only solution I found so far is to run on 2G, which seems to run properly.

I've tried to change APN, to set the radio to LTE/CMDA/GSM, without success.

It pisses me so much. I didn't even flash or root the phone, I'm on stock 4.2.2, baseband M9615A-CEFWMAZM-2.0.1700.48

Kernel 3.4.0-perf-g7ce11cd

Build JDQ39.

N4 is KHE3.

F***k, so long waiting for my first Nexus Experience and so many disappointments.

I understand the fact that android is also about customization, which I enjoy, but come on, having to tweak the radio OTB ?

How can you bear this ? How can such problems occur with a phone coming from the last batch ?

I'm starting to think that it wasn't a high end fair priced phone, but rather a 350 euro fragile and cheapo constructed phone.

Possibly getting my money back and buy XZ/GS4, depending on how I crave for stock.

Out of harware problems, I love how android has evolved. It's starting to be really polished and fast. 4.2 is so intuitive and good looking, *Sigh*

Hi

Has anyone experienced this kind of data drop problem.

When phone is in idle (screen off) after some time when i wake it up i see that bars are gray (meaning data is off) and i run to start gtalk and i can see that data connection is being restored. Data loss is not gtalk specific if i just wake it after some idle time data bars are gray and after5-10seconds data is restored back.

Tried calling my provider and guy from technical department was really good telling me that he can't find any data drop from their log.

Stock rom, not rooted OEM state 4.2.2, JDQ39, non of the power management app isn't installed that could bring down data connection to save battery or anything similar.

Tried 2 APN's (2 of them available from my provider) and got the same problem on both of them.

[Nexus 4 Q&A, Help & Troubleshooting] dnkbro:
I've been having this problem since I first got my phone in February. Stock 4.2.1/4.2.2, both unrooted and rooted. At first, I was using my AT&T sim card. I was using the correct APN settings (using XDA threads and another site I can't remember) and would have data drops. I would have full bars in blue with the H symbol but the internet would just idle about 60-70% of the time. The interesting this is sometimes if I had been on the internet for a little while, it would start working without the data drops. The problem was much more common going from periods of not having used the internet. Eventually I got extremely fed up and was about to RMA the device. I decided to use my T-Mobile SIM and the problem seemed to go away. However, the issue reared its ugly head again. I noticed it happened more frequently when I was using 3rd party apps such as Reddit News and such. The other day it got to the point where the phone was just not loading webpages anymore unless I was on Wi-Fi. I ended up calling Google and requesting a warranty exchange. It should be here by tomorrow so I will report back. In my opinion, it's a hardware issue affecting some phones. I've factory reset my phone, changed the APN settings (which only helped temporarily), and tried two different SIM cards. I work for T-Mobile and sell plenty of Nexus 4's and haven't had a customer come back with the issue (knock on wood).

Will keep you guys updated...
