Hi guys. I've looked around and it seems that data drops are fairly common as of lately. I would like to find out what exactly the problem is.
Here's my situation. Data drops first occurred about a week ago, I was running RBJ and Harsh kernel with hsic fix in. Mainly it happens when exiting wifi range. Went back to nandroid with RBJ/Bricked and it was fine. Tried harsh again issue reappeared. Tried flashing pre hsic kernels and problem persisted. Full wipe, dirty flashes, different kernels etc. Problem is still there intermittently. Now I'm running stock everything and it seems ok for now, but I did experience it once. I guess more testing is needed. I'd think it could be carrier issues, especially as Orange UK confirmed they are having problems at (that would include T-Mobile) but my wife is on the same carrier and doesn't seem to have this problem.
So what you say? What rom/kernel combo you had issue on and on which one you didn't? Can anyone see a pattern?
Problem first appeared:
RBJ
HARSH
Orange UK
West London

As suggested per _ICE_
Post these please.

Hardware: rev_x (10 or 11) <-- go to boot loader to check
ROM:
Kernel:
Network:
Location: City, Country
Description: One of the below or other

1. There is 3g or H sign above signal bar but the tiny arrow pointing up is constantly showing and you can't get access to internet ?
2. There is no 3g or H sign above signal bar but you have blue signal bars ?
3. No 3g or H, grey signal bars and all of the sudden signal bars dias appear and reappear

What do you mean by no data?

Do you mean
1. There is 3g or H sign above signal bar but the tiny arrow pointing up is constantly showing and you can't get access to internet ?
2. There is no 3g or H sign above signal bar but you have blue signal bars ?
3. No 3g or H, grey signal bars and all of the sudden signal bars dias appear and reappear ?

Most of the times I get issue 1 but simple air plane mode solves the problem

no1 and greyed out icon (no connection to google servers which atomatically mean no connection). The rest exactly as you described in that line.

Simply everyone put the same commits in their kernels and therefore caused them all to fail. Those HSIC fix broke other stuff too which is why everyone was reporting the samething. They've been reverted in CM and Franco and other kernels.

I'd agree that it was the case if it didn't keep happening after going back to complete stock via flashing images.

I wonder if something happened to sim along the way?

I doubt it is a sim issue. I get the same thing when I am in different areas of my house. Living room is great but the master bedroom and media room give me data drops. Have you tested to see if maybe this is the same thing happening to you? Certain areas causing it?

My phone will have full bars and show the H but out of nowhere I see the data drop, buts its only in certain areas. It has never happened in the living room where I spend most of my time. Oh and I am not on WiFi because I disconnected Time Warners crappy service and am waiting for Verizon to come set up if anyone is wondering why I was using data instead of Wifi .

Are you on stock?

And areas I'm affected in are a lot larger. I'm talking 25miles here.

Same issue here, it's driving me nuts.
The problem is, I have full service and with a data connection with a H.
Whenever I use an app or anything that would use the data connection, it wouldn't work. It just won't work. It does this, sometimes and sometimes in certain areas.
Say I have full service with a strong data connection, I'll use instagram and refresh, the arrows for data connection won't be there and nothing will show.
It does this constantly. I'm running the stock rom with Franco's r23 kernel. It's been doing this with the stock kernel as well. Using T-Mobile in NYC
It's quite annoying, and I really don't want to wipe and or flash another rom as it happens once in a while.

Read the link above. Something doesn't play well together. From the logs it looks like problem lies in loading apn.

I have no other provider sim with data to test it. Will test wife's Orange sim in a day or two, just to eliminate sim card as a reason.

Testing time :)
*#*#4636#*#*
Set to LTE/GSM/CDMA AUTO ( PRL) seems to make data work normal. Still testing though.
Give it a go.

I only noticed the data drop issue recently, but that might be because I'm on wifi the vast majority of the time. Undercover - I'm experiencing basically the same issue as you are, however my data signal seems to reconnect itself after about 15-20 seconds.

Running stock rooted ROM, motley kernel here, UVed quite a bit, though I don't know if that would cause any problems. Will try changing some APN settings tomorrow and see what happens :)

When having been connected to wifi overnight and leaving the wifi area, the phone does not switch over to mobile data. The signal bars stay grey.
I have to toggle airplane mode, and then it connects fine. Another fix is to search for provider and reconnect to the network (takes longer obviously)
Is this the same bug?

I seem to have problem with both data and also wifi.
Right now I am looking at my phone connected to wifi and its all grayed out and streaming music stopped. It seems that problem is worse when I have same time connected to bluetooth.
Something is seriously wrong with the new Android.l

No problems here. I'm on T-Mobile if that helps. Cm10.1 and Franco r28.

I get dropped/inconsistent signals as well but only in certain areas of my house or certain parts of the city I live in. I'll have a few bars of H and then poof no signal. I can almost predict when I'm going to run in to that little problem because my loading times and such will be all around slower. Even though I should have a fast connection according to my signal bars. During times when I'm experiencing fast download speeds my signal never falters. PS I'm completely stock, not unlocked, not rooted.

    The problem seems to occur most for me when leaving a Wi-Fi signal area after being on Wi-Fi for a long while. Immediately afterwards, the 3g/data signal goes haywire, disconnecting and reconnecting several times over a few minutes of use. Things seem to work better if I manually disable Wi-Fi before leaving the house; I still get occasional drops, but only once every few hours, which really isn't too bad. (EDIT: Never mind, the problem came back.) This leads me to suspect that it has something to do with transitioning between Wi-Fi and 3G, but of course that's just a guess.

    Undercover, how's that new setting (LTE/GSM/CDMA AUTO (PRL)) working out so far? Also, I don't think you mentioned whether your data drops were "permanent" (i.e., requiring something like toggling airplane mode or rebooting to fix) or temporary (data drops, then reconnects itself after a little while).

    EDIT: I was able to grab this from logcat around the time a data drop happened:

    Code:

    I have no idea if this is helpful or informative at all ... perhaps someone more knowledgeable than me would be able to make some sense of this , or tell me what information might be more useful.

    Interesting. That gives me an idea. Hold tight.
    Edit. Nah, forget it.


    I think i found my fix.

    Rebooted, in terminal

    logcat -b radio

Low and behold, my sim in her phone has no data (same symptoms as no 1) ,her card in mine working fine. Will report again once i change my sim.

    Hi guys. I've looked around and it seems that data drops are fairly common as of lately. I would like to find out what exactly the problem is.
    Here's my situation. Data drops first occurred about a week ago, I was running RBJ and Harsh kernel with hsic fix in. Mainly it happens when exiting wifi range. Went back to nandroid with RBJ/Bricked and it was fine. Tried harsh again issue reappeared. Tried flashing pre hsic kernels and problem persisted. Full wipe, dirty flashes, different kernels etc. Problem is still there intermittently. Now I'm running stock everything and it seems ok for now, but I did experience it once. I guess more testing is needed. I'd think it could be carrier issues, especially as Orange UK confirmed they are having problems at (that would include T-Mobile) but my wife is on the same carrier and doesn't seem to have this problem.
    So what you say? What rom/kernel combo you had issue on and on which one you didn't? Can anyone see a pattern?
    Problem first appeared:
    RBJ
    HARSH
    Orange UK
    West London

    As suggested per _ICE_
    Post these please.

    Hardware: rev_x (10 or 11) <-- go to boot loader to check
    ROM:
    Kernel:
    Network:
    Location: City, Country
    Description: One of the below or other

    1. There is 3g or H sign above signal bar but the tiny arrow pointing up is constantly showing and you can't get access to internet ?
    2. There is no 3g or H sign above signal bar but you have blue signal bars ?
    3. No 3g or H, grey signal bars and all of the sudden signal bars dias appear and reappear

    What do you mean by no data?

    Do you mean
    1. There is 3g or H sign above signal bar but the tiny arrow pointing up is constantly showing and you can't get access to internet ?
    2. There is no 3g or H sign above signal bar but you have blue signal bars ?
    3. No 3g or H, grey signal bars and all of the sudden signal bars dias appear and reappear ?

    Most of the times I get issue 1 but simple air plane mode solves the problem

    After updating my phone to 4.2.2, i've never experienced any data drops and also, I've noticed that my signal is much better. Could anyone agree with my findings?

    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...)
