GPS & Cell/Data Connection Issue - AT&T Samsung Galaxy S II Skyrocket SGH-I727

I have a reoccurring issue of losing cellular signal whenever I run applications that use a constant GPS and data connection. For example, I use Glympse almost daily, and I find that after 10-15 minutes Glympse reports "no data connection" and my 4G LTE symbol is replaced with the no signal (circle w/line through it) symbol. I cant get phone calls, texts, data, nothing. This seems to happen with any app that uses GPS and data like Glympse, Google Maps/NAV, Navigon, etc. If I use an app that just uses data (Pandora, Sirius, etc) with no GPS the connection is solid and I have no issues. I am able to get the connection back by turning on airplane mode then turning it off again. If I just leave it, the connection never comes back, until I turn on airplane mode or reboot.
Has anyone else seen this issue? Hoping that a fix or ICS comes out in the next couple months that will resolve this. Between this and the screen issues I am thinking about taking it back when the Note is released and seeing if they will let me swap it out.

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.

[Q] Losing data connection on GPS

Hello all,
I'm having this problem with my HTC Desire S.
Everytime I start an app that uses my GPS, and tries to get a fix. Like maps, runkeeper or GPS Status. I lose my data connection.
I can go to my settings then. And in my settings its still turned on, but I dont have the little icon on top, neither do I have an internet connection.
I can turn off my data connection then, en turn it back on. And then it reconnects again, and both my GPS and data connection are working.
Untill I exit the app that uses my gps, and if after an hour or so I use my GPS again, the problem repeats itself.
Anyone else had this problem and / or know a fix for it?
I've used the search, but nothing came up.
Hello,
I had the same problem but it resolved with GPS TEST application from market.
Turn on GPS and mobiile network then run app Gps Test and from settings menu clear a-gps then update Gps and wait to lock gps to satellites.
After that you can use some navigation software such iGO, Sygic .. and so ..
I solved my problem with this way.

Switching between WLAN & WWAN?

so I am curious if anyone has run into this issue (or if it's not an issue and rather it's just the way the phone behaves, perhaps someone can tell me if there is a workaround in settings?):
it seems to me that turning wifi on doesn't always make wifi the active connection. it's intermittent, but it appears to happen frequently.
I found out because I started to download some stuff out of my audiogalaxy collection (which REQUIRES wifi, it doesn't let you do it on mobile data) and it kept telling me to enable wifi to continue downloading.
speed tests confirmed that I was on mobile data, not wifi... even though wifi was turned on and connected.
I've also noticed that occasionally, you'll turn wifi on and it won't replace the mobile data icon... I imagine it's all related.
any of you guys encountering this or should I go get myself a replacement?

Data Goes Away / Very Low Sometimes

On certain ROMs, such as Cataclysm, my data signal goes away after disconnecting from the WiFi. But this has been happening on several other ROMs, too, and I can't seem to find the reason behind it. In case it matters, I'm using my phone on Sprint, data works fine with the stock ROM, and problem starting occurring more often after the 4.4.1 update. Any suggestions?

What you described looks similar to my problem.
I’ve been flashing 4.4 and then 4.4.1 ROMs on my Nexus 5 since I’ve got it early November, but I have not updated bootloader and radio up until yesterday. This week being on Slim 4.4.2 beta 1.5 I couldn’t connect to mobile data even though I had 4 bars and it was showing 3G or H (no LTE here yet, at least for me). GPS was fixing my location on Google maps, but navigation was not able to recalculate the route and was not moving my position along the way. Only when I switched from navigation to map, it was showing me as moving accordingly. Maps also couldn’t search for the address I was looking for. Now I realize it was a data connection problem.
So I thought it’s because I’m using 4.4.2 ROM on 4.4 bootloader and radio. Yesterday I downloaded Google 4.4.2 factory image and fastboot flashed all (efrant, your guide is irreplaceable!), formatted cache, did a factory reset and all. I wanted to have 100% factory state device. What a surprise today morning, when I realized I have no mobile data. Orange 4 bars signal with 3G or H. No internet though. Rebooted – the same: max signal, no internet. I turned Airplane mode on and off. Signal is back and I have internet, but bars still stay orange. So I rebooted. No internet on full 4 orange bars. Airplane mode switch on and off – mobile data regained, yet still orange.
When I reached the office I turned on WiFi. Got strong WiFi connection, bars went white, both WiFi bars and mobile bars (in Quick Settings). I switched off WiFi – mobile data is not reconnecting, staying orange, showing 3G or H. Sometimes it’s coming back after few seconds, sometimes it requires switching Airplane mode on and off to bring it back.
WTHell?
I was never putting much attention to mobile data because at home and in office I’m on WiFi, and while driving I’m listening to audiobooks so I don’t see what’s going on with mobile data. Sometimes I take a train, and then I’m browsing xda – I don’t recall having connection issues in train up until recently. But what I recall now, for some time, when coming back home and turning on WiFi, email notifications were popping up immediately. Does it mean I had no mobile data and phone synced only after it had WiFi?
This is annoying and driving me mad. Do I have to fastboot flash 4.4 factory image to see if it’s gone on 4.4?
Any ideas what can I check before going through factory img flash again?
Does your data eventually kick in after a few minutes, or are you without data for an extended time after disconnecting wifi? I know with Cataclysm if you enable Smart Radio it takes some time for data to ramp up after disconnecting wifi, although I'm not sure about how other ROMs handle this.
I'm on full stock 4.4.2 now, just roorted with SuperSU 1.80, no mods at all. I wanted to check if it is related to custom ROMs or general.
It's random, after switching WiFi off, mobile data sometimes comes back after minute (rarely) but more often I need to switch Airplane mode on and off to bring internet back, but even this does not work all the time.
Mobile toogle shows 4 bars with 3G or H in orange colour (screen attached) when there's no data or there is data. Never goes white for mobile data (I remember it used to). Now it becomes white only after I switch on WiFi (2nd screen attached).
Hopefully it's not this but I've been seeing more and more people starting to experience it. Mine started acting up slowly and then now it's having the issue in the thread linked below.

I've seen this thread, but my problem is different. I'm not getting the "emergency calls only" message. I can call or receive calls without problems. It's mobile data which can't reconect after switching off WiFi, even though mobile signal is strong - 4 bars and it's showing its on 3G or H. And Why it stays orange even after it finaly regains mobile data?

[6039s] Google Play (I think) wakelock issue

I can't figure this out to save my life. 6039s Android 6. No root. No special mods. Nothing. Bone stock.
In the middle of the day today I suddenly started getting a horrendous wakelock. I thought it was a Google Play issue but it turned out that it's some kind of mobile data issue.
My LTE connection isn't working right. It's slow for some apps and non existent for others.
For instance my sports score app loads at 2G speeds. My web browser seems to work okay. But my t mobile tuesday's app gives me a big warning that I'm not connected to the internet at all. And the Google Play app gives me all kinds of warning that I need to have background data enabled to use Play, but background data IS enabled.
Making matters worse, when this issue is happening my phone enters a miserable and unstoppable wake lock that drains the battery so fast it hard to even charge it. And it saps up the system resources to heavily that the phone slows down to a crawl and can't be used for anything else. Not to mention the phone gets insanely hot from the excess processing. Could a tower issue that's causing a connection problem cause such a wakelock?
I tried doing a reset of the radio connections in settings, but I don't think it actually did anything because all my settings and connections were still there. Still had my wifi password, BT connections, etc.
I tried wiping cache in recovery but it didn't work. Says it did it. But on reboot I didn't get the "app 1 of 82 is updating". So I don't think it actually did that either.
I cannot figure this out to save my life.
I thought maybe it was a tower issue. But my wife has the exact same phone and it's working fine. I called T Mobile and they said they are having a tower problem near my house, but still...wife's phone is fine. And I've seen this problem now in 3 different locations across about a 5-6 mile range. So I have to have been on more than 1 tower in that time.
When I turn on wifi and have a wifi connection the problem goes away entirely. That's telling me that the problem is the system getting upset that it doesn't have a solid internet connection. Changing the connection to 3G or 2G does not solve the issue.
The problem lasted the whole second half of yesterday, was fine overnight while I left wifi on, was fine on day 2 when I was back to 4G networks, and then suddenly is back again.
Anyone got any ideas or suggestions?
Is there some server android is trying to stay in constant contact with that I can block the connection to? Perhaps limit background data to something? I can't figure out what.
This update was irrelevant. Turned out to be a red herring. Still having the problem.
Nevermind this update. STill having the problem
I give up. I'm about to throw the phone against a wall to smash it. The system has become totally loused up. Whenever it goes into these goofy wakelock states the system is so overtaxed that everything takes forever to process. Nothing solves it.
And its' getting worse. Now I have oddly limited connectivity.
T Mobile's tech support was useless. They had me thinking it was a tower issue. That was 3 days ago. Now suddenly they have no records of a tower issue in my area over the last week.
I can make voice calls. But I cant' send text messages. I can use my web browser to search the internet, but not SOME apps that need data like a weather app or Google Play. Other apps work fine to pull data.
Yet it says I have an LTE connection the whole time.
This is the single weirdest issue I've ever seen on Android.
What in the hell could have just jumped in out of nowhere and started causing these issues?
