data hanging

Hi,
Does anyone have this problem on their phone? Every now and then, when I am doing a data related function, data hangs as though it is not connected even though I am in a perfect 4g coverage area and the 4g sysmbol is still on. I know its hanging because the arrow to the right of the 4g symbol stays lit green. It either starts working 5 minutes later on its own or I turn wifi on and off. I have the newest sim card installed.
Any thoughts?
Thanks

probably a software related issue
the only time i experience that is when i lose connectivity with the network, as in the signal bars or 3G/4G arrows are all greyed

Yea dude i noticed even tho i have wifi set to never it always shuts off or i should say loses connection i hate it because i have to pull down status bar hit it off then on wifi is definitely effed on stock too. Anyone else experiencing this? I know its a problem cuz my g2x i could leave it alobe for an hour in hibernate come back and wifi still good to go anyone have any ideas? Or is it a s2 problem witg wifi cutting off. Like i said the icon will still be there but i wont have connection and 50% of the time i have wifi icon and 4g

Same issue here, in two different phones I've had. Not sure what the issue is. In fact, opening this page, my data was hanging for a minute, irony.

for this issue you can configure how WiFi behaves, but the settings are only accessible via spareparts or custom ROMs
I set my wifi to never sleep while on charger

But this happens to me when my wifi is off. Only on the cellar data connection.

I had this issue after giving juice defender superuser permissions. It seemed that it would not turn data back on when I had the screen on. I'm not sure if this applies to you, but I no longer gave juice defender su and everything was fine. a lot of those functions in that app do not seem to play nicely with this phone yet anyway.

Yep, for several weeks now. I thought it was my ROM.

It happens to me several times a day. Usually right after a voice call. I just put on flight mode for a second, switch it off and data is back. I have no idea what's causing this. Always on 4g, wifi is working perfectly.

+1 to everything already mentioned.
I was in Vegas this weekend and had HORRIBLY slow/no data at all. Like has been mentioned, the green arrow with just stay lit. thought i was the rom, i nandroided back to stock, same issue. Hope this is fixed soon it is hella annoying.

This fixed it for me
I have had this same issue for a while, here's how to fix it. Go to Titanium backup, I found out that there're two versions of "My account" on the list, so I frozed the old one, then go to task manager "kill all", the 4G icon will disappear. Open up "My account" again, the 4G reappears but as soon as I close the app, the 4G icon would disappear.
Hope it helps someone

I too have similar problems where my data hangs or doesnt want to connect. Then a few minutes later, it will decide to start working. This happens even in full signal regions. Stock rom and/or BeastMod rom...
Not sure why it happens :S

For those having problems and have tmobile my account on phone freeze it or uninstall it i guarantee it fixes your data problems trust me. I to had problems just like you guys and i was told to uninstall my account i was like what? What the hell is that going to do but believe me when i say it worked! I actually unfroze it to see if the problem would come back (4g and wifi on at same time) or cutting out. And it did. So i refroze my account and bam 4g disapeared while wifi on. This has fixed all my wifi and data problem phone works flawless now! Basically i think t-mobile trying to snoop with our data. Scumbags

This is happening to me. The phone is driving me mad. It happens constantly. The "up arrow" in the 4g icon will light up, and all data will freeze. I stare at loading screens all day long. It freezes anywhere from 30 seconds to 2 minutes. Then it will fix itself, then it will happen again within 2-5 minutes. I'm furious with this phone.
Wifi works great. It's not dependent on my location, it happens no matter where I am. Doesn't matter what I do, nothing prevents it from happening. Of course, the Airplane mode toggle or resetting APNs and all that will do the trick to fix it temporarily, but it will only happen again 5 minutes later.
I'm on stock, unrooted. I am ready to throw this phone at the wall. Has anybody else managed to actually fix it or get a response from Samsung/T-Mobile?

I should have read this thread before buying this phone. This is so annoying. I tried to put the phone in flight mode. It fixed for a min and back to problem.

I'm having the same problem. I didn't have this problem until I updated to 2.3.6. Anyone else still on an earlier version?

Same things been happening to me lately, its awfully annoying. Makes me want to throw my phone across the room sometimes.

Anyone else having WiFi issues on CM10 nightlies?

I have a gsm Nexus and I'm running the Aug21 nightly, but I've had this issue for awhile, at least 2 or 3 nightlies. I'm not sure how long because I was on vacation in a WiFi free zone all of last week.
My WiFi can't find any networks but can't turn off. It perpetually says 'searching for networks' but never finds any. If I try to switch it off, the switch hangs on Off with a darker shade of grey for a few seconds then flips back to On.
If I reboot the phone, everything is fine for a few hours. WiFi can turn on and off and doesn't seem to have any connection issues.
My battery life doesn't seem to be suffering all that much, so it seems that WiFi is sleeping normally.
I haven't any logs because it's hard to pinpoint the exact moment when things go wrong.
I haven't tried wiping yet, but I'll give it a try if no one has any other advice.
Is anyone else having this?

Did you figure out how to fix the problem? I'm experiencing the exact same problem.

I wound up doing a factory reset and installing CM again. If that doesn't work, format /system and wipe data before flashing. It comes back every once in awhile. I have no idea what caused it, but a reset'll fix damn near anything. I had an issue where my phone thought it was charging even when it wasn't plugged in and had to return it to get a new logic board, I might've just had a lemon. Have you had any other hardware issues?

I had this issue for a while too. After I did a full wipe and went to the latest nightly it stopped happening. Also I turned on the 'always keep wifi on during sleep' option in settings.

I get it too. It's random, and it is not fixed by changing the kernel. Very frustrating.

WiFi Power Save Mode Back On!

After I finally got tired of being nagged about about the LH2 update, I updated. Bye bye root,Titanium and recovery Noticed that my GS3 started dropping WiFi again (3" from router). So I dutifully go into service screen with *#0011# and disabled it. Expected after a firmware update. However, I noticed the same behavior the next day or two. So I disable it again and performed an immediate reboot. Go back only to discover that WPSM has been turned on. WTF!?!?!? :crying:

same thing here...

Every time you restart/reboot it goes back to "on"

man, what rom and kernel are you using, I had a similar problem, so I tried different kernels until one worked, I am no dev but I think that the update/rom/kernels have some things to do with it, guess it's just finding a combination that works.
Good luck.

Search for and install WiFi High Performance Widget from the play store. You will have run some tests to verify its working.
If you go into the *#0011# menu the button will show that it is on. But other apps will show Power Management is off.
Just looked and it may be that Power Save Mode may be different than Power Mgmt. Not sure but it may be something to start from when checking this stuff.
Hope this helps you out a little. Sorry I dont know more right off hand.

Totally stock, and rooted. I am also having problems now with Titanium uploading to Google Drive. Only successful with WPSM off. Still hit or miss though. Unrelated(I think), but I can now receive calls on WiFi calling.

*#0011# not working
For some strange reason, the *#0011# method of pulling up the menu to access the Wi-Fi power saving mode ON/OFF button is no longer working for me. I dial it in the keypad but no menu appears anymore. What's strange is that it used to. Anyone else having this issue?
Also, does keeping the power saving mode ON restrict the range of the Wi-Fi signal as well? Or simply make Wi-Fi turn off when the phone is sleeping?

Can't download mms messages..

So I turn my mobile network off to conserve battery. But if somebody sends me any mms (picture or multi-person) and I turn on my network after the fact, it just perpetually says downloading.

It probably doesn't really start properly since data was off. Maybe try to rebooting your phone to see if it will do it then.
Are you manually turning it off and on? You could try an app that automates it so that when you get a message and the screen lights up (assuming you have that setting enabled) it turns on and see if that helps. Though I have found that using such apps will sometimes cause your data to not reenable and require either toggling manually, toggling airplane mode, or rebooting.

Yes I am using the toggle in the shade. I will give the app a shot but my guess would be failure since the network seems to need to be on when the message comes in rather than an automated toggle after the fact

If you enable screen on for notifications it may have data back on before the download actually starts. It may not work. But I have used screen off profiles before and not had issues with MMS other than the occasional failure to reenable. Do you turn WiFi and GPS off? It may be enough to allow for leaving data on.

If it doesn't work I would just leave it on. Data alone probably won't hurt battery to terribly bad.

well. what ive noticed is that in NJ it constantly works to stay connected and really drains power, but in NC i can go about 2 days without a problem.

I had that problem but I let the data settle for about 30 seconds before trying to download the mms and it works for me. Turn off auto retrieve too. I don't need to do that on my s3 of course

That's because NJ sucks balls.... Try going to settings, applications and force stop the messaging app. Then open messages and try downloading again. If for some reason that doesn't work, a reboot should.

Try this:
Be sure that you have good connection and you might want to force quit messages if this continues.

[Q] A couple of Day 1 questions/issues

I've just gone through my first day of use with the LGOG, and a few issues have come to my attention.
The first is that while I was at work, i felt the device getting hot in my pocket. When I checked to see what was going on, it was searching for GPS. I had tried to use Maps, and it couldn't find me so later on I turned on location services/satellite GPS so it could actually find me. I haven't noticed it since. Could that have been the solution?
Issue 2 was that it seemed that my WiFi was turning on by itself, and it was draining my battery searching for a signal. I had turned it off when I left my house, but it seemed like it came back on and started searching in vain for a signal. I turned it off again, and haven't had that issue since. Has anyone else had this happen, or did I accidentally activate WiFi without knowing it and that's all there is to it?
One other issue I was having was with the text cursor freaking out and going to the front of my texts. I can't really remember for sure if it has happened since I updated to ZV9, so does anyone know if ZV9 had a fix for that or if I've just been lucky the past few hours?
Thats all I can think of for now, thanks for any help you guys can give me!

For your wifi randomly turning on make sure you have connection optimization off (system settings, mobile networks). ZV9 shouldve fixed the crazy text issue. Not sure about your device heating up with gps, maybe you had Google maps running in the background trying to pick up your location. Hope I helped!

I turned off the connection optimization, what exactly is its function? Will I get decreased mobile network performance with it off?
Also, I am wondering if anyone knows about the Qualcomm Enhanced Location Service. Does it help or hurt performance/battery life/etc...?

The connection optimizer basically turns on wifi to search for a signal and then shuts off if it can't pick up anything. Of course this only happens when you have it checked and using data. I'm not certain what the qualcomm enhancement location service does besides help you getting a gps lock.. I know I've always had it enabled and gotten an instant lock almost all the time with great battery life. On a side note, you'll love the speed and build of this phone, plus our devs are working hard to bring us jellybean sooner than sprint/lg

Thanks for your help, I will leave optimizer off and turn qualcomm on.
I came from the Evo Shift, and I am just blown away with the speed, screen clarity, and beauty of this device. I've had to go back to my old shift a couple times to get a thing or two off of it or check what apps I'm forgetting and each time I get pissed at how slow and small it is haha. I'm loving it so far, and hopefully with these small issues worked out I will love it even more. When the roms start dropping, well thats just a bonus =]

In regards to notifications, is there any way to limit update intervals for facebook? I feel like its going to eat my battery up if its always telling me about facebook stuff the moment its posted lol.
Also, is there any way to increase the rate that the notification light blinks? I feel its not blinking regularly enough for me to notice it if I've got a text or something.

Under facebook settings just change interval to update less regularly. I use flash blink. It actually flashes the LED light to let me know. Unless of course you want to be private about it.

To add a little about the Connections Optimizer: It's Sprint thing that they're adding to all of their phones. It basically turns on wifi briefly, even when wifi is off, to try to connect to open wifi networks. I'm pretty sure it's an effort by Sprint to keep people off their 3g/4g network and on wifi whenever possible to reduce bandwidth usage. It is also incredibly annoying, because it notifies me of the free wifi in my city (that's strong enough to locate, but not strong enough to transfer data and stay connected) every time I am in certain areas. The pop-up about new open networks also gets in the way of receiving phone calls sometimes. Turn it off. Android already connects to your remembered wifi networks automatically, and I think you can handle the wifi on/off toggling.

I couldn't stand connection optimizer. Walking through NYC to go to work, I'd look down and see my phone actually connecting to and using ANY open wifi signal on my walk down the blocks. I would think that's a huge security issue for phones to randomly connect to any network it sees. Just think of how well easily it could be to rig a router to sniff all those data packets!
