Alright, I really need some help from the big boys here.
I have had my N1 since release. I have T-Mobile and no data plan. Everything I do is over wifi.
On Friday, I saw the 3g icon on my phone for the first time. It appeared out of nowhere and just flips between 3G and E since T-Mobile just blocks data for non-plan users. This was killing the battery life of the phone.
I called Google and they ran me through *#*#4636#*#* to disable the data connection. This fixed the problem for a while; However after a while the phone will give a message that there is no service provider and will reconnect to T-Mobile (it has never done this before outside of phone boots). When it is back up the 3G/E cycling starts again. Even worse the data connection still lists as disabled and will not re-enable. I have to pop the battery out while it is running to get back in to disable it.
Google thinks its an app but I have removed everything but Touchdown and K9 which I don't think are the problem. I have used Android OS Monitor and I do see connections to 64.15.75.218 and 209.44.107.13 which are hot beds for malware and when I uninstall any app these connections vanish temporarily. But they come back after a few hours.
Anyone seen this before or know a way to track IP connections to a particular app?
I have no solution for tracing 'malicious' software but it is possible to just disable all mobile data usage.
Settings/Wireless and network settings/ Mobile networks > "Data enabled"
If you unselect this there should be no more data transfer while on the mobile network.
I do not have that option. Google Rep said it was only in froyo.
Problem is I did the same thing for 2.1 but it keeps coming back on. Even with wifi the phone connects to these ips so who knows what it is doing.
3G isn't used only for data, you can do voice on 3G.
Could be T-Mobile expanding 3g into your are where you didn't have coverage before.
Call T-Mobile and make sure you're not actually using data.
As for tracking applications, you can use System Panel Pro of the market to monitor how much data applications are using.
I know I am not using data. The T-Mobile account page is pretty detailed and I am unable to do anything online when wifi is off. 3G has also been available for a while here as I know others that use it.
I will check out system panel.
Thanks.

It is indeed only on Froyo, however, Froyo is out now, so install it and you'll instantly benefit.
A few more things:
Were you receiving or sending MMS (picture/video messages) when the 3G icon popped up? This is normal and doesn't usually come out of your data balance.
If you'd like to be triple-sure you're not using data, go into the APN settings. Edit the APN name - e.g. change tmobile.com to nomobile.com. Now it *really* shouldn't be able to access data.
Smarphones would be well to do to have a Zonealarm/little snitch type app for this purpose.
Id imagine ad based apps wouldnt be too happy about it. At the least an app that reports IPs times , and IN/OUT info.
I never use SMS or mms and have not gotten any during this time.
My concern is not related to getting charges but with unwanted use of my phone or data. When the data connection auto enables it will go through my battery in a matter or hours and who knows what the phone may be doing.
I know I can turn this off and make sure data is not used - in fact I have already done this. However when smoke enters room you don't just put a towel under the door and forget about it. I want to find the source of this and stop it because the behavior is not normal.
I agree something like zone alarm would be good. You should be able prevent or track an app activities for situations like this. If I knew what was connecting to these IPs and enabling the data connection I could stop it and report the app or submit a bug request. Right now I am just all alone.
I did try system panel which seems like a nice app but it does not give me good information on network usage by app. OSMonitor is better at connection monitoring but doesn't list by app. Why has no one thought to monitor network threads by app?
Try alogcat maybe? Any time you notice the icon suddenly appearing, save a copy of the logcat and comb through it.
alogcat may work. Figured out OSMonitor had something similar and filtered by app.
Now I just gotta wait I guess. Still not enough info to relate to IP though.
You should know that the data connection setting isn't an enforcement for the entire phone. It only acts as a notice to applications on whether or not to use data in the background.
Developers are supposed to respect those settings, but they are not enforced.
There is a free program called Network Statistics which is no longer in the market. I will backup the apk for you and upload it so you can use it. It shows the amount of data used by each app.
I too had a data hungry app issue and this helped me solve it immediately.
I'm just at work ATM, so I'll do it this evening. (Almost midday now here in Australia )
Cheers,
Ross
@JCopernicus
I am aware of this which is why I want to track this problem down.
@Ross
That sounds great. I appreciate the help. Not sure if tracking data usage is enough since I don't think the app is sending a lot of data. But I am willing to try anything.
I should be getting froyo soon so maybe that will help as well.
This is what I do when I want to ensure I don't use Data. Go I. To wireless connections. Mobile Networks, and then access points. Create a new one. I usually call it No Data. The for the apn, I just make something dumb, like no.data.com, and then save. After I'll select that as my apn.
The issue is not about the use of the data connection. I have done this and can guarantee the phone cannot use any cell data network. The problem is an app is trying to use it anyway even when it is disabled. Even if you ignore that as a concerning activity the constant 3G searching reduces the battery life to a mere hours.
I appreciate the help, but my issue is not with how to disable the data connection. Its about identifying malware on my device, and tracking an app calls to a specific IP.
Again,k 3g doesn't mean data. 3g is also used for voice.
If you only want to use "2g" switch your phone over to gsm only through 4636 or through the menu where it says "use 2g only".
You will never see the 3g icon again.
If you wan't to be 100% sure no app is calling an IP, then do a factory reset. Install apps one by one, monitor them through the various options given in this thread already.
You will not be able to prevent an application from "calling home" unless you modify the app itself. Apps use the data connection provided to them by the OS however they see fit.
Every app you install has a permissions prompt that will tell you it want's internet access.

The Android "3G", "H", "E" or "G" icon denotes data. It may also appear temporarily when making the connection necessary to transmit MMS. It does not appear when the phone is using voice over 3G without a data connection.
Actually, this may be a T-Mobile issue - they just enabled the ability to do "pay as you go" data on ALL plans without a data plan, so they may be the ones turning on the ability to do data. You'd still need to authorize it in your browser, and I think it costs about $1/1MB so it is totally not worth it.
May be worth looking into because it wouldn't surprise me if their new "service" is screwing things up.
I am aware of 3G voice but the 3G status icon is related to data flow. I have had the phone since launch and posted this because this behavior is not normal. Even Google was perplexed by what it is doing. And as I said it is not constrained by the 4636 settings.
And I disagree that an app can use the network connection as they see fit. Rights are given to perform its intended purpose; anything else is malicious.
I run CM7 nightlies on my Tmobile N1. Recently I killed my cable Internet/TV connection at home and have been using the built in WiFi tether for my home devices.
While it typically works great (for free), the data on my N1 will lock up. I have full 3G/HSDPA at my house. Using #*#*4636*#*# it states I am connected but fails to ping or load up any data on the phone or through its shared connection.
The only way to fix the problem is to toggle airplane mode and re-enable the WiFi Tether or sometimes a reset is required.
I've changed to several Gingerbread roms, flashed various radios, and even exchanged SIM cards.
Is this behavior normal or not? For regular web surfing I can live with it, but the main problem is that I cannot download anything without it getting interrupted (like updated nightlies or 50mb+ files).
Bumpity
No one has any problems with their WiFi sharing?
i used my phones internet as my regular home internet for a month. i used up about 25 gigs. i streamed videos, downloaded videos and podcasts with no interruptions. don't know what your problem could be. i was using cyan 6.1.1
I occasionally have experienced that issue, but it seems as if you have it much more frequently than I ever did. I would mainly get it when I tethered from areas with bad reception.
You state that you have full 3G/HSPA at your house. I am wondering how many bars of reception you happen to have. Also, try setting your phone to WCDMA Only in that 4636 menu. That seemed to decrease the frequency at which it happened for me.
I also found that once in a while, I could get tethered data working again by simply using the phone's native web browser to access any data. Good luck with the issue.

I typically have full bars of signal usually reading around -100dbm. When the internet drops, it drops completely; maps, browser, apps, etc all fail and I can't "jump start" it other then toggling airplane mode or resetting the phone. Typically a reset is best.
Perhaps I'll flash back to CM 6.1 and test it over the weekend. I'll do a backup of my current setup if things aren't fixed.
The purpose of this thread was simply to see if others have experienced the same issues and if it was worth "trying" to fix.
It might be a case of overheating device - it'll be good to test different ROMs and kernels.
I don't think the device is over heating at all rather then just a carrier issue. I flashed to CM 6.1.1 over the weekend and immediately found I was still having data issues (where it would work for like 5 minutes then drop out).
I did find that EDGE was a solid connection and stayed connected while I downloaded CM7 and GAPPS. I put a call into Tmobile and yacked at them for several hours. They escalated it up several times in their engineering department and so we'll see. I spoke to HTC a few times in there and they didn't think it was a handset problem either.
I guess we can close this thread as it doesn't seem to be a wide spread problem. I am running a stable version of CM7 now and we'll see.
@above: I have tested different radios, roms, and kernels. This thread started out as a issue with WiFi Tethering but ended up being the phone simply dropping its data connection. I originally was curious if this wifi sharing behavior was normal or not.

I was on the phone with a T-Mobile rep yesterday in regards to the weak signal in my home. I never had issues with T-Mobile and signal strength, but it has gotten pretty bad around my home, where I usually am only able to get two bars of strength around my home, three when I am lucky.
I brought this all up w/ T-Mobile, they said there has been no service changes around my area, but the representative recommended that we use WiFi Calling in areas it is available.
I know this service is free, but I never bothered trying it, does it really work when dealing with poor signal strength? Does it impact battery life by any ways? Also, does it cause any sort of delay when calling people? And lastly, I'd imagine this includes texting via WiFi, correct?
If it is all as good as it sounds, I might go ahead with it, if not, I'll just ask T-Mobile about some sort of signal booster around my home.
Thanks!
Wifi calling can fix the poor range problem. You connect to Wifi and calls go through it instead of the GSM network. It works with texting. Just go ahead and try it. You don't have to pay any extra money for it. If you wanted a signal booster, I think you have to pay for it.
I have been using it for the past few days since posting it, and it seems just fine!
Let's say I use this option and walk out of WiFi signal, would my call automatically get disconnected? Also, does HD voice work on this?

Yes, if you walk out of range of wifi, your call will disconnect. Also, one thing to note is that it cannot be used on custom roms, however, with the release of this feature on this Nexus 6, we should see it on AOSP/CM in a few months. With google's project FI, this feature could be worked on by google and improve. As for HD voice, I'm pretty sure it works.
Actually, you CAN use Wi-Fi calling on custom ROMs, as long as the ROM developer didn't mess with it's functionality. (Granted, you most likely limited to ROMs that aren't drastically altered/customized, but at least they will be de-bloated...) I had an S4 with a custom ROM and I used Wi-Fi calling frequently--just have to check to make sure it's available.
I see people are still responding here - I have been using WiFi calling for about a couple of months now, it has been working perfectly fine. I had some random instances of dropped calls, I called T-Mobile and asked them about the issue, they told me it was related with my router, they went ahead and sent me a special router that is built for WiFi Calling (To be honest, I have no idea what the hardware capabilities on the router is, but it sure as hell beats the $20 Router I bought 5 years ago )
That being said, WiFi calling has been amazing for me, no more issues. Text messages are sent, calls are received, and everything works. It is a beauty of a function.
The only complaint I have is that sometimes if I hop in my car, drive away and am still on a call, the call will get disconnected (I now just avoid making calls while I am leaving my house). Another issue is that when I connect to any WiFi network, whether at a mall or a friends house, I sometimes do face issues as there may be some sort of hardware capabilities needed in order for the feature to work properly.
Hope that helps for people considering WiFi calling!
I'm not sure what happened, but over the past couple of months I've been experiencing some sub par data speeds when trying to stream something from my phone, whether it be over LTE or wifi...actually happened on my 6p as well.
I'm on T-mobile, always had unlimited data, nothing has every changed. The first time I've noticed this is when I switched over to 6.0 for the first time, regardless of ROM or kernel, data always bad.
For example, if I wanted to watch an Unbox Therapy video on youtube at 1080p, I'd buffer every 10 seconds when before, the entire video would load within about 30 seconds, never buffering.
Wondering if I'm alone on this.
T-mobile is "optimizing" all streaming video services regardless of whether the plan owner is on Binge-on program or the service is supported. Optimizing is a fancy way of saying that every streaming video goes ~1.5mbit/s. Use this app as a free VPN service and it should bypass the speed limit from what I've seen.

you don't read the news or pay attention to anything that's going on, do you? turn off Tmobiles Binge On service, and it'll fix your issue. Tmobiles binge on service reduces your network speed to only 1.5mbps when watching YouTube or any other video service, even if its not included in binge on, no matter what your actual data speeds are.

Constant notifications "Wi-Fi Calling preferences updated to optimize network exp."
So, aside from the common touchscreen and proximity sensor issues, I'm getting this notification constantly that is driving me crazy. If I swipe it away it comes back many times per day. It can't be disabled. I've seen reports of it, but it's not widespread. I've not had this issue on any of my other phones, Samsung or otherwise. The only way to get rid of it is to turn off Wi-Fi Calling. I suppose it could possibly be an issue with the wireless in my home. I use an eero router system. But like I said, it works with all my other devices no problem. Anyone else get this?
what carrier?
so notification pops up only when the wifi-calling is on?
try this:
download samsung members app from galaxy store, click get help (bottom), send report. once you submit a ticket, samsung will be able to tell you what is causing the issue.
Yeah I hate that it does this

I'm on T-Mobile. And almost every instance I could find of this issue on a Samsung device (via google search), the user was also using T-Mobile. And yes, it only happens when WIFI calling is enabled.

Are you also on T-Mobile?
T-Mobile here, and also having the same issue. I just muted/Silenced all the notifications, but they still pop up in the bar.
I have seen it a couple of times at home (also on T-Mobile), but this past weekend, when using a car hotspot (AT&T), it kept showing up over and over again.
S20 FE Unlocked purchased from Samsung directly. Just transferred from Verizon to T-Mobile. At my home, cellular signal is so weak that the phone is basically unusable for calls. Wi-Fi calling is a necessity so I set the Wi-Fi Calling network preference to "Wi-Fi preferred". It doesn't take long for these notifications to show up when the phone changes back to "Cellular preferred" mode on its own. My work around is to turn on Airplane Mode, wait for it to engage, then re-enable Wi-Fi. This works to keep Wi-Fi calling active and stops the constant notifications. I just have to remember to de-select Airplane Mode when I leave the house. A big PITA.
When I was on Verizon the phone would remain in whatever network preference I selected without issue.
i have a workaround for this using tasker, the catch being that you need to have the android 11 (one ui 3.0) update. if you're still on android 10, the custom setting this watches for doesn't exist yet...it was only introduced in the android 11 update.
