[Q] [BoneStock v3.3] Strange data reception issue - Verizon Samsung Galaxy S III

Sorry if this has been mentioned before. I did extensive searching without finding anything before posting.
I have been having some very strange data connection issues with my Verizon S3 running BoneStock v3.3 (awesome rom BTW, much thanks to andybones and all contributers) over the past few days. Starting a few days back, my signal strength and transfer rates while at work were much lower than normal. While investigating this, I found myself exploring the settings menus (About Phone > Status and More settings > Mobile Networks) to investigate the signal strength more often than normal (and I believe it had been the first time I had ever been to the "Mobile Networks" view).
This morning, I noticed that I had a 3g connection only at my house (this is unusual as I normally have a very strong 4g connection at home and a pretty decent one at work). Toggling in and out of airplane mode, or rebooting the phone would result in a 4g connection for about 1-2 minutes or so before it would again drop back to 3g. Using the Speedtest app, I would get about 0.5Mbps or so down, and the upstream test would not even finish before showing "Network Communication Issues" and dropping back to 3g. Additionally, my phone has been running really hot and the battery has been draining much faster than usual. Meanwhile, I had ruled out a regional network issue by testing my wife's iPhone 5, which was maintaining a solid 4g connection while mine was dropping.
While Googling for this issue, I ran across lots of articles/discussions referencing the bad OTA update Verizon sent out back in June. It struck me how perfectly the typical list of symptoms for that update matched what I was seeing. However I couldn't see why my phone would be having such similar issues, as I never received that OTA update before flashing BoneStock, and have had weeks on BoneStock with no problems at all.
Just for kicks, I switched the "More settings > Mobile Networks > Network Mode" to "Global", then switched it back to "CDMA/LTE/EVDO", then rebooted the device, and this has apparently fixed my issue!
To be absolutely clear... the current setting for "Network Mode" was already set to "CDMA/LTE/EVDO" when I checked the setting. I merely switched it, then switched it back. That was 2 hours ago, and my connection has been solid as a rock since then and the phone temperature and battery life has gone back to normal.
Doing more research, I saw that apparently the bad Verizon OTA update configured "Network Mode" to "Global" by default, and that many had fixed their connection issues by switching this to "CDMA/LTE/EVDO". Sounds very similar to my problem, except my UI was not showing that it was currently set to Global.
So, hooray that it's working, but I'm not sure what I did or how it was broken in the first place. My working theory is that the phone's Network Mode was actually set to Global somehow through some other mechanism but the UI was not displaying the setting properly, and by switching it and switching it back I overwrote that setting.
Does this ring a bell for anyone? I'd love to figure out what exactly happened, and hopefully prevent someone else from going through the hair pulling that I went through. Thanks in advance!

Network Problem with my phone

Hello all,
Lately (meaning, the last couple of days -- perhaps 3 or 4), my phone has been unable to get a Verizon data network connection for a certain amount of time (4G or 3G). WiFi works fine. However, anything else doesn't work, say, for a few minutes, or a hour or so. Sometimes, a reboot will fix the problem, but sometimes it won't.
The odd thing is, the "4G-LTE" icon is displayed and shows activity (up and down arrows blinking), yet I can't browse the web, update the weather, update Facebook, check email, etc., etc.
Does anyone have any ideas? Running BAMF 1.3.2. I am in the middle of NYC (plenty of 4G service). Yes, Mobile Network is enabled in the Settings. Tried a battery pull as described above AND a SIM card pull. Still no fix.
I had a similar problem a few days after I got my Thunderbolt. I was still on stock yet. I ended up going to the Verizon store and they did a hard reset to fix it. It sucked because I lost all my data but since it was new I didn't have much on it. If you back up everything with Titanium Backup it shouldn't be too bad tho, factory reset is under "SD card and storage" in the settings menu.

There have been many problems with the TB and data/network problems as of late. I believe it to be because of this new 4G rollout that is coming Thursday, plus the fact we will be seeing an OTA quite soon they are propbably preparing the network for that, thus giving all of us all these weird problems that we have been having.
(everything above is just rumor and based on my 100% factual opinions )

You are describing the same problem I'm having and I also live in NYC. But, I have no problems getting data when I force the phone into 3G mode only.
I notice the data connection problem even though the 4G symbol is up when I don't have cell reception for a while...like being underground while on the subway.
Turning the phone off and on or rebooting seems to fix the issue. I'm thinking the phone has handoff issues with whatever tower is near by.
Anywho, I did the "data fix" by changing the EVDO setting from eHRPD to Rev. A. I dunno if that'll do anything.

2.20 "3G/4G connectivity fixes"

So the 2.20 OTA update released claims that it provides 3G/4G connectivity fixes... Does anyone know if this solves the occasional loss of connectivity (mobile network says "disconnected," "disconnected due to the network being unavailable," or "turning on" endlessly) requiring airplane mode toggle problem?
I discovered within the first few weeks of owning the phone (including 2 swaps which all did the same thing) that any time I leave a major area with good coverage my phone consistently does not work (texts do not send, phone calls cannot be placed or received, mobile network says disconnected or turning on), even though sometimes I may have 1-3 bars and the 4G symbol. Airplane mode only sometimes fixes the problem, and then it may or may not happen again within a few minutes if I am in the same area.
It's driving me crazy and I don't want to send it in and receive a refurbished phone... For all I know I could get one of the same early release devices that has the exact same problem.
I was at a friend's house on a nearby island this past weekend and the phone simply would not work. Nothing. I had 2-3 bars and "4G" THE WHOLE TIME. Upon leaving the island and returning home it is now working.
i never had a connection drop after updating to this rom.its awesome and battery life is insane.

Bluetooth causing extremely slow wifi

So I've had my m8 since launch, about May of 2014. I've never once had a problem with my wifi, until last week. All of a sudden, I noticed all of my wifi connections (home, work, etc) are all extremely slow. Speed tests are barely getting 1mbps down or up, and the test itself is very erratic, bobbing up and down the whole time. All my other devices are fine, and nothing with any of my wifi connections has changed. I uninstalled about 3 apps that I had installed within the last month, with no change. Verizon sent me a replacement m8, and I got it yesterday, loaded up all my stuff, and low and behold, still slow wifi.
After talking with numerous Verizon techs, they can't solve it, even after multiple factory resets. However, this morning I saw a post while googling it, not an m8 but still android. They said that if Bluetooth is on, but not connected to a device, it could cause issues. So I turned my bluetooth off, and speeds were perfect, getting exactly what my internet connection is. Turned it back on, and back to 1mbps.
So one, why is this happening? I've read that the bluetooth and wifi antennas are the same, and that could cause interference, but it should not be this bad. Second, why did this just now all of a sudden start? I didn't usually leave bluetooth on, but I got a new car about 3 months ago, and decided to leave it on to automatically connect when I'm driving. But it was fine until last week, why the change?
Have you discovered anything new? I've had my Verizon m8 since April 2014 and have always left bluetooth on for my fitbit to sync. I only recently started having problems and can't identify any recent update that happened this month that would cause it. When bluetooth is on and a device is connected my wifi performance is very slow - 100+ ms ping, 1-2Mbps up/down doing a speedtest. Turn bluetooth off and speed test again then wifi performance jumps to 20Mbps up/down with 12ms ping times to the same speedtest server.
I have factory reset my phone 3 times, changed wifi channels, tried 2 different routers and 1 access point. None of the wifi changes affected speeds until bluetooth was turned off. It seems to be a little quicker 3-5 Mbps with bluetooth on and no devices paired but still that's not acceptable.

I too have had bluetooth on for months to be able to connect to my car, never had a problem until about a month or so ago. I did two factory resets, and everything seemed to work fine, but after a day or so, when all my apps were back on the phone, it would start up again. I have a hard time believing a specific app is doing this, unless it was one of the HTC Home updates or something.
Verizon sent me a replacement M8, I got all my apps on it, and the same thing, after a day or so it's super slow with Bluetooth on, horrible ping and less than 2mbps down and up.
So then I contacted HTC directly, did all their troubleshooting, factory reset, and it's still there. They sent me a replacement as well. I turned it on, but did not put my sim into it. I spent 2 days with it, and only downloaded the Speedtest app, nothing else. Speeds are fine with bluetooth on. I then downloaded the rest of my apps (I actually do have quite a few apps, so if it's one of them it will be a pain to figure out which one). It's been two days now and speeds are still good with bluetooth on. Later today I'm going to offically move over to this phone and put my sim in it.
It's just really frustrating to keep turning bluetooth off and on again, and there should be no reason for this to be happening out of the blue all of a sudden.

Strange issue, but from how you described it, it must be a 3rd party application. What I would do in this situation, is do the factory reset, and download 5 apps at a time. Until you narrow it down to the 5 apps that are causing the issue, then you can narrow it down much easier out of the 5 applications. A pain, yes. but once you figure out the app that's causing the issue, you may decide you don't need it, or you only use it once in awhile and can remove it, until you need it, or possibly download an app ops application from the Playstore and remove the Bluetooth permissions and see if that fixes it.
Best of luck.
Seems to help...
I just tried the solution offered in another forum (xda won't let me post the link so I'll copy and paste the information here:
Open page with the available "Wi-Fi" networks (Settings, WI-FI)
Tap on the "3 dots" in the upper right corner
"Wi-Fi Direct"
Tap on the "3 dots" in the upper right corner
"Rename device"
Replace "Android_ed2c" with "HTC One" (or whatever you want) and hit "OK"
Before doing this I had a 300ms ping when Bluetooth is on, and very low bandwidth. Now with Bluetooth on the wifi ping is around 50ms (normal for my home internet) and the bandwidth is back to normal. Time will tell if it sticks, but so far so good!
So I had been running all my apps on my replacement phone for about a week now, and have had no problems. The other day I officially swapped my sim card into this new phone, and for two days now, it's been fine. Bluetooth and wifi are on constantly, and I see no issues with bandwidth. So who knows why the last two devices had a problem, but for now it seems to be fixed.
Having the same issue, originally posted on reddit and then found this thread: https://www.reddit.com/r/techsupport/comments/3kv6z6/wifi_issues_with_multiple_phones/
Turned off bluetooth and it's fine... Will be experimenting with my gf's m8 this weekend.

Same HTC M8 issue - very slow WiFi when Bluetooth is running
Same problem on an HTC M8... speedof_dot_me speed test shows 96 ms latency with D/L at 0.07 mbps (really!) on an 11 mbps router. Turned off Bluetooth, and voilla! Latency dropped by 85% and WiFi speeds increased by a factor of 60! I suspect an HTC issue since an August or September update... since this wasn't occurring prior to August.
Verizon sent me a replacement M8 that was on 4.x.x android. I updated via on-air update (not rooted) to Lollipop and installed all my apps. Everything was fine. That night, it did a security update and, since then, my wifi+bluetooth were horked when turned on together.
Do, I did a factory reset (which doesn't undo the updates), but since doing the factory reset and installing just the basic Play-store updates 24 hours ago, the problem is not back.
I'm going to slowly add back my normal apps this time.
Solved on one plus one
Hello, i had since two weeks the similar issue. when bluetooth is switchef on (unconnected), wifi is very slow. in the past this different, so no issue with hardware and frequencies. Finally, I found out that it was linked to an App that accesses Bluetooth.
In my case it was the App Accu-Chek, I read in a big forum that it was linked to a Garmin app.
Uninstalling the App solved the issue.
My wife has a similar issue on Stock Galaxy S4 mini with that App.
This is definitely app-related. I tried force closing out of a bunch of apps that weren't related to the video I was playing and it seemed to fix the bandwidth issue with bluetooth enabled. Guess I'll need to experiment with closing certain apps until I find the culprit.
I was having this same problem. It looks like the RetailMeNot App was the culprit for me.

You sir deserve a cookie. Thanks for pointing out the worst app of 2015.
Solved on my Phone!
I used to have the same problem. I am having a Sony Xperia Z1 Compact and a Smartband Talk. At the beginning everything was fine but after sometime (strongly caused by a software related issue) I begin to face the same problem. While bluetooth is on WiFi bandwith dropped to a very little amount (around 0,02- 0,01 Mbits/s). Then I read somewhere, about how to verify whether it is a software or hardware issue via checking it in the Safe Mode. So I unpaired by smartband talk and uninstalled the smartband talk software (smartband talk requires a bluetooth connection for functioning). Then restarted my phone in to safe mode by tapping and holding the power off on the shutdown menu. I downloaded the smartband talk software and turned on my bluetooth and paired my smartband talk again. Then restarted my phone in to normal mode. And voila, problem solved.
It is not a guaranteed method but worth to try.
Wish you good luck.

modem_err - signal loss - random-reboot - high battery drain

Hi,
my phone lately shows an high battery drain, random reboots and signal losses.
Aside from supersu and adaway everything is stock. last-kmsg shows "modem_err"
A few days ago I updated my phone from MMB29V to MOB30H, right after this I went on holiday. (left country)
While being there everything worked fine.
But right after I comeback home the phone started to act strange (see title).
Anyone an idea what could cause the behaviour?
Maybe the update? And I didn't noticed it in holiday because of my disabled data connection?
I tried:
a full wipe, reflash of stock image
flash of old radio
looked out for wake locks (there are non)
using phone without apps (only stock)
Might flashing old bootloader/kernel help?
Maybe interesting:
My provider (Klarmobil (T-Mobile DE third-party)) tends to switch my network mode between 3G and HSPA,
from what I heard and see this depends on my data usage. (HSPA while surfing, 3G while idling). I have the "feeling"
it disconnects when it tries to switch.
Thanks for your help!
Edit:
Added another set of logfiles, showing a "signal-loss", it got so far to ask for my pin again.
Sadly errors still keep happening. I tried the march build and also a custom kernel, no change :crying:

Data Connection Drops on Moto G XT1045 (T-Mobile US)

I was curious if anyone else experienced or has familiarity with this issue. I've been dealing with this since I got the phone almost a year ago. Sometimes when my phone has been idling and I return to check something, the data connection will be unusable. The 3G icon will be visible but internet unavailable (4G works fine, but I prefer to have my phone set to 3G only). It's possible to wait 30-60 seconds for the connection to reset itself, or under settings, switching "Cellular data" or Airplane mode also restores it. Aside from that, the connection is mostly reliable & I don't have any usability issues once data has restored.
I've always ran CM & LOS on this phone so I haven't tried using a stock ROM (solution suggested in an older thread... Mobile data cutting out). I've also flashed the latest Lollipop Radio Firmware (fsg & modem). Thanks for any help.
Edit: I think this may have had something to do with visual voicemail being enabled. I've since switched to AT&T where VVM hasn't worked at all (they suggest using their app) and the problem has gone away.
