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

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?

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 .

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.

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 think its an android issue
had this problem on my htc desire and now i have it on my n4
but it occured since 4.0
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.

I have trying to use the HD2 over the last 3 days and getting real problems with intermittent signal loss.
I know i have low signal from the mobile operator in some parts of my home but that has never been a problem with other HTC phones i used before. If the signal was too weak it would just drop out but come back if i moved a bit.
With the HD2 once the signal indicator turns red it stays that way even if i move to a strong signal area.
The weird thing is sometimes i would leave the phone sitting in one place with four bars and then minutes later it would show up with no signal and i can't receive calls.
Even stranger is that in all these cases where there is no apparent signal, all i need to do is press the send button to try making a call and the signal "magically" re-appears and all is fine. I've tried at least four differnt radios as well as the energy ROM ... no change.
Any ideas ? this is reaallly frustrating!!!!!!
do the problems resemble what I experienced here?:

change radio ROM, well experiment with several of them by trial and error (read the sticky/tutorial first).
OR
buy an indoor signal booster.
Well, regardless of the radio version ive had really odd intermitant service.
the best way ive found to help this is turn off 3G / HSDPA
Doing this forces the device to remain on GPRS, it means the battery lasts a hell of a lot longer and it doent drop the connection every time the device feels like trying to connect with HSDPA or drops it for no apparent reason.

it seem that you were losing data connection .... i'm a lot worse off ... i lose data AND voice .. all connectivity ... so i don't receive calls
as i said the weird thing is as soon as press send to initiate a call,cthe signal bars come back and everything works fine!!
as i said, stop 3G from working, when switching between the two due to what ever reason the HD2 decides to drop it will kill your connection, voice and all until it switches back. there is an issue with 3G and im wondering if its everyone or just folk using TMOUS radio and thus recieving the extra RAM
To disable 3G/HSDPA to test,
Open Comm Manager and click on Phone (not the on/off switch) to go to phone options. Scroll to bottom and select BAND. Switch network type from Auto to GSM.
3G/HSDPA is only needed for internet surfing. Time, weather, stock updates and email downloads don't really benefit from it. So turning it off this way will make these type data connections go through the EDGE network which is plenty fast enough for it. When you need to surf the net, go back and switch it to Auto and you will get 3G or faster speeds for that.

If its just 3G then its probable just T-Mobile or then again a Hardware/Firmware issue
try a different ROM, Radio
I have this same issue I running a T-Mobile USA (using radio 2.12 but then again it was doing it on 2.15 as well) and it just drops all connectivity and says no service I have to search the network again.
My phone is unlocked I don't know if that might have anything to do with it as well
I've had this problem on my HD2 since i got it.
Edge (E), works but slow as all get out. 2-4s ping times or time outs. 3G (and when i say 3G i mean when it says 3G in the status bar) doesn't work at all. HSDPA (H) works great, WHEN it stays that way, which it doesn't.
It can switch between 3G to H every 10 seconds.
And i'm using it for tethering primarily, which makes working painful. Lose your VPN and SSH sessions constantly. Some days it's ok. But most, horrible. btw, i'm in the Denver area.
I've tried stock roms and custom roms (primarily Energy). All radios. Nothing fixes it!
This is the only thing I don't like about my HD2 and/or t-mobile. And it's a whopper. I'm almost ready to get another phone or carrier, depending on what's causing this.

I have 4 HD2's with one having the problem you describe and have come to the conclusion it's a hardware issue. Probably a cold solder joint on the antenna lead.
In WinMo or Android the signal bars jump all over the place but the signal level in 'about phone' shows a constant signal even though the bars show nothing. I don't drop to many calls but miss more than a few incoming. I travel for 5-8 hrs in the same area everyday and very familiar of good and bad areas of reception. I have tried stock/cooked ROM's/Radio's with no noticeable difference.
I'll probably send mine in to HTC to be looked at.
Here are the odds:
1).Whenever I exit a wifi area or a no-radio area, MT4G picks up the mobile network signal ridiculously slow, if you look into the status bar, it says the mobile network is turning on...sometimes I got lucky, but usually it takes more than 1 min or ever...
2).Things can turn even worse that, I lost call signal and mobile network signal at the same time when I exit a no-radio area or wifi covered area. No bars, no G/E/3G/H, AT THE SAME TIME.
3). Sometimes, even if you see bars there and 3G icon, you can't dial or receive any call, it disconnect immediately.
I called TMO, they said signal in my area is fine and they even re-registered my SIM card. I did a full wipe and re-installed Virtuous Unity 2.37.0, good for a day or two, and the problem kicked back in.
BTW, I'm on Radio 26.09.04.26_M
I also uninstalled some suspicious apps that I just installed or updated within the days I first ran into this problem. No luck...
I really love this ROM, anybody could help?

Hi All,
I have been having problems with my S3 for some time now.
HSDPA. Sometimes it works and sometimes it does not. It works as if it was set up to work on demand.
Where could it be set up like that? I have checked every menu and cannot find anything.

HSDPA works and in a few seconds stops. No data at all. Then HSDPA works again for a few seconds and so on. No pattern or anything. I tried to keep it running by keeping Skype work, but it would disconnect from data completely again. It is connected to HSDPA network and I can make calls over that, but no data.
Sounds like your being ping-pong'ed between antennas.
Usually flashing a eastern modem (I can recommend the ZN... ones) should fix it since they are optimized for large cities which have this issue.
Also, having a proxy server configured in the APN settings may cause this issue if it's overloaded and causes connection resets.
If you have one configured, write down the settings(in case you need it ) and try removing it.

Some good ideas.
Heading to the modem collection thread.
No proxy in APN.
An interesting thing is, that I went to another city a few hundred km away and everything was ok, so I thought it was the phone and it started working again. I am back in my area and it is happening again. The only thing is, no one else is having these porblems, even people using S3.
EDIT:Just fashed ZNLH3 using CWM and will start testing. Right after starting the phone, there is no data active.
EDIT2: I forgot to mention, that when I switch to GSM only mode, EDGE works just fin, no disconnects at all.
Try fast dormancy apps from play store and disable it.
The switching between hsdp and 3g is not a problem. It is a technology to preserve your data usage when you are not using.

There is no problem switching between 3g and H, there is a problem with switching between HSDPA and NOTHING.

Position has not effect, it happens wherever I am.
I will try with ping and see.
EDIT: PIng seems to make the connection persist. Will keep it running and see.
Been running ping for over an hour now and no data cutoffs. Means there is something that keeps disconnecting me.
How do I find out what and fix that?
To answer my own question:
I instaled DLI1 last night and so far in almost an hour not a single data blackout!
I was wrong blackouts still happen
Using DLI1 and FD switch, it now works much better, but there are still blackouts.
I will look for the GSM Monitor software and see if that can help me identify the problem..
problem is your location ur phone is jumping between 2 bad signals/towers and one of those towers does not have 3g on it only 2g
I say this because I have same problem at home. certain areas of house amazing 3g reception others .ir does not work and ye so .ir flicks between them and I often eexperience "blackout" . .signal says on H but no data throughput.

Of course, I have had it set up like that since the beginning.
Remember that my problem is not with constant switching between HSDPA and EDGe, but with switching from HSDPA to nothing.
After a couple of days of using my Nexus 4 i've noticed a problem with the way it handles the transition between Wifi and 3G internet.
Usually it works just as expected, when I switch Wifi off (or just go out of wifi range) it automatically switches to 3G internet (coverage icon in blue). The problem is that sometimes, after switching wifi off, it doesn't turn on 3G data (coverage icon remains grey). The only way I can get 3G internet back is turning Airplane Mode on, and then off again. ¿Am I missing something here? I've seen other people having this problem with other phones, but no workaround yet

This happens with my gf's Galaxy S3 too...
I think this is just a network coverage issue. My old mytouch 4g slide had the same problem. Usually it switches quickly if I'm in an area with great reception. If I'm somewhere with weak reception, it takes a little longer.

Well, I don't think this is a network coverage problem because when this problem happens, it can stay for hours with no 3G internet, it just doesn't even try. But then I switch airplane mode on and then off again, and it achieves 3G data connectivity almost immediately. Also, with the same SIM card I didn't have this problem with an iPhone 3GS.
Well, i've been investigating a little bit, and I've just found it in the AOSP issues tracker as "Android Issue #2207"
I've also found some apps like "3G Connection Fix Free" that seems to try to fix it
I'll try them and report back my findings
I think I have this problem too sometimes. I think my phone has other issues, I'm about to send it back to Google because it keeps dropping cell signals as well, but I definitely have this same problem.
Yes, it happened to me as well yesterday.
After I had more than ten hours at home using wifi, it can't switch to 3G automatically when I left home. The only way I did is reboot the phone.
But if I just connected to wifi for few hours it is OK.
Before I use One X, I don't have this problem before, but the problem is I can't access to internet once I am using wifi for more than 36 hours about.
I think there is big problem for Android system related to wifi and 3G access.
I don't think it's a nexus issue at all. It is definitely something else. My phone hands over form wifi to H+ in a matter of seconds every-time.
I believe you might have a coverage issue.
I am having the same issue, and can confirm it is NOT related to coverage. A reboot of the phone will immediately fix the problem. Have also tried disabling the mobile network, then re-enabling it, with no success.

Well, nothing i've tried has worked so far. It looks like if it stays connected to Wifi for many hours (for example overnight), it just won't switch to mobile internet unitl I reboot or do the airplane mode trick. I also have wiped everything and reinstalled the stock rom, but the problem is still there. Has anybody fixed it?
Had this problem with my Nexus One, with my Transformer 300 and now with my Nexus 4.
I use German provider O2 and after doing some research, many people suffer this problem and have O2. I thought it was related to my SIM card and I ordered a new one without success. My wife has O2, too. She never had a problem, not with her HTC Desire, not with her Galaxy Nexus.
I worked around with free app WifiFixer Free, which connects to 3G every 60 minutes. This doesn't seem to work on Jelly Bean, though.
The problem is all but new and I am out of ideas. I now use an app that enters and leaves airplane mode upon leaving a Wi-Fi network. But it yet has to prove that it works...
Any news in here? have the same problem and don't know how to solve it. It's so annoying

I have this problem too. Completely stock nexus 4. It doesn't happen all the time but when it does its very annoying.

After a couple of days of using my Nexus 4 i've noticed a problem with the way it handles the transition between Wifi and 3G internet.
Usually it works just as expected, when I switch Wifi off (or just go out of wifi range) it automatically switches to 3G internet (coverage icon in blue). The problem is that sometimes, after switching wifi off, it doesn't turn on 3G data (coverage icon remains grey). The only way I can get 3G internet back is turning Airplane Mode on, and then off again. ¿Am I missing something here? I've seen other people having this problem with other phones, but no workaround yet

The one thing that's keeping me from fully enjoying my new Nexus 4---hassles with radios, both wifi & cellular.
1) On my home wifi network on all devices except the Nexus 4 I see solid, constant download speeds of 25Mbps. My Nexus 4 consistently only gives me 4-6Mbps. If I disconnect/reconnect sometimes I can see speeds slightly higher than that, but only temporarily. This isn't generally a huge deal because 4-6Mbps is fast enough for most things on a phone, it just bugs me that every other device in the house gets 25Mbps.
2) Of bigger annoyance is my cellular data connection, it drops off multiple times per day. The cellular signal strength indicates full bars, along with the 'H' icon indicating I'm connected to T-Mobiles HSPA+ network. Voice still works fine but the data connection is dead--nothing will connect--Speedtest, maps, Google Search, Facebook, etc. This forces me to either turn on/off Airplane mode or reboot the phone completely to regain my cellular data connection. On my previous SGS2 I never experienced this issue. It drives me nuts to not be able to pull up a phone number, directions etc at the times I need it most.
Does anybody have any similar experiences or suggestions on how to remedy these issues?
Edit---FYI I'm fully stock but rooted. 4.2.1 update not yet applied.
1) Check APN settings and make sure your account is properly provisioned by calling T-Mo CSRs. I had a similar issue with my Nexus One back in the day that was fixed with a reboot after they reprovisioned my account.
2) Flash factory image, in case it was a bad flash of the radio. It happens.
3) If 1 & 2 fails, or you don't want to try #2, call the Nexus hotline and get yourself a replacement.

Called TMobile and had them reset my account, I'll keep an eye on it the next couple of days.
Right now I'm downloading a cached Google map via WiFi and it is slooooow.
I also notice on edge the signal is inconsistent.
Hi
The Wi-Fi issue is something happening to others, seems to be a driver bug.

Wifi connectivity is my biggest gripe. I'll step 6 feet away from my router and I lose a bar. A couple rooms away I fluctuate between 1 and 0 bars.

Did you ever find a cure for this? I am having the exact same issues on my O2UK Nexus 4, anytime I want to use the data connection its almost guaranteed not to work and involve reboots, Airplane mode on and off etc
Im having the same issues. My data just drops wifi and cellular. I dont get full signal wifi or cellular. I live in india and flashed the latest .54 which was released in india recently. I managed to at least get cellular data going but my strength still low and data drops still on both wifi and cellular. Its super frustrating. Any ideas?
try reflashing the OS on your phone and try changing the wifi channel on your router.
changing the channel on my wireless router really helped signal to all of my devices. there may be lots of interference on the channel you're on.

I may reflash OS but i just got the phone today so ill slow down a bit. I flashed the radio one would think that would be enough? Anyway I have many other devices on my wifi without an issue and i used wifi analyser and theres no overlap with other routers and i experience this on 2g 3g and wifi so it looks like some modem problem. Unfortunately the phone was bought 3 months ago in the States and im here in india so im kind of stuck
There are known issues with the Nexus 4 wifi speeds slowing for no apparent reason. Also, known issues with the LOS (loss of signal). You can find information and bug reports on both of these issues.

I dad see some threads reporting this issue. Unfortunately i dont see any solutions or resolved threads. Additionally people either have it they dont as i see it i cant see people witching sides. Its just a little frustrating. Any opinions on whether kernel swapping will help?
Did a full flash from scratch. No progress. Also i went to my friends place and signal was perfect for like 4 hrs straight but every other place ive been since has seen choppy signal.

Pretty bad. I ran a test a few weeks ago and I can go up to 450 feet from my router (old Linksys) without a problem, and after that it gets iffy, and finally disconnects at 500 feet. I am seeing an average of 20 Mbps on wifi. Now if I can only get my cellular connection (non-wifi) to go faster than 1 Mpbs max I would have a usable phone.
I have a slightly diff issue.
If I reboot my phone, I connect to my router no problem. If I turn wifi off (to save battery) and then turn it back on.... it shows my AP's as out of range.... but I do see my neighbours AP's. I also have an N10 with has no issues at all with wifi (and none of my other divises have issues either).
When I bought the N4 they seemed to be having an issue with it when setting it up.... but I was not paying close attention. I am wondering if I have a bad phone on top of the "normal" wifi issues that other are experiencing.
Think I will revert back to stock and swap it for another phone to see if I can at least just turn off / on the wifi rather then reboot to connect (how sad is that?)

**** UPDATE ****
I picked up a cheap belkin router and set it to AP mode.
My N4 has no issues at all with it. Connects when I want it to right away and is fast / solid connection.
