Preventing data connection

I've just received my Desire, and have asked O2 for a new data plan (I used to be on Blackberry). That won't go through until midnight today, and they will charge me £3 mer MB with NO LIMIT until then! So, I need a way to turn data off (apart from WIFI) as soon as I turn the phone on (it's currently charging). I've read some reports of people turning it off, but certain apps turn it on again.
What's the simplest way to do this please, until tomorrow? Thanks!

Hold down the power button until the menu comes up then turn off mobile network.

Ok great, thanks. Yea now I've turned it on, it's pretty obvious.
Is there any chance of an app turning it on again without my knowledge? In some forums people say it can happen, but I THINK that may have been with WinMo.

I've heard of it in the past but not on 2.1, a rogue application maybe but they shouldn't do. It would be pretty easy to notice if you were out of wifi range though as the data icon would appear in the notification bar, your best bet would be to just check on it if you install any app that mentions data in it's software permissions.

Ok I'll do that. I'll also look for an app that'll show me data usage. I know there are some around.
Thanks for your help.

I'm in the same position as you (but my data plan doesn't go live till the 26th! lol), so I set up the phone to WiFi only thanks to the option on the setting screen, and so far it has only connected when I switched on the data toggle. I'll post here if I come across any apps that will connect though.

I've installed a program called NetCounter. It doesn't seem to count Wifi with the Desire (others have had the same problem), but for you and I that doesn't matter. I've got it set to alert me if 'somehow' the phone starts using data from O2. So it's just an extra safeguard. Sorry you have to put up with that until the 26!

I have the same question and I was told APNDroid does it too. Is it better to use APNDroid or the bult-in option?

Just add the widgets for network data, GPS, Wifi to the home screen (I've stuck mine under the clock) easy to turn on and off with single keys presses then rather than holding the power button down. I've also added the bluetooth shortcut but that takes a massive 2 key presses to turn on or off. I've found it useful for saving battery life as well.

He wanted the quickest way after turning it on, holding the power button is quicker than finding and adding those widgets for the first time.

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.

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.

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.

[FIX] Dropping WIFI (disconnect/reconnect issues)? Check this thread.

I know I had a problem with WIFI dropping every few minutes and disconnecting/reconnecting all the time. Causing streaming issues, internet issues and freeze issues if on lockscreen. Well, I have fixed this for myself and wanted to share.
To insure this doesn't happen, just follow these steps:
1. Dial *#0011#
2. Hit the left menu softkey to bring up the menu, and select 'Wifi'
3. Turn OFF the 'Wifi Power Saving'
4. Exit, and Reboot.
Ever since then, I haven't had issues. I am on AT&T GS3. If you are having this issue, please report back here with your model and if this fix worked.
Just trying to help. Good day all!

I'm not entirely certain this was happening, but had noticed some oddities. Not as bad as your experience, however.
But I did make the change to see how it would affect battery life. I am on the Sprint network.

Didnt notice a difference and after a reboot it turns back on.
Sent from my SPH-L710 using xda premium

I don't have issues at home but I do with the WiFi at work so I'll try it tomorrow and let you know how it works out. It disconnects and reconnects every 5 seconds and I'm not exaggerating either.
I think the WAP may be a little wonky but my HTC Desire HD had no problem with it.

Mine turned back on after reboot as well.

I am working through logcats as well. I reverted the setting to mimic the problem, and I am going to look at logcats.
If I can see what is exactly triggering it, I will make a flashable fix.
In the meantime, I have another S3 here that I have the power save off on and I still haven't seen a drop yet. So preliminary, I think this is a temporary fix until I can find out root problem.

Hope you find a fix

I have a similar problem. Mine doesn't disconnect per-se, however I did notice while browsing through Flipboard that I wasn't getting any signal sometimes when trying to access a page with a lot of content. Page loading came to a stop. Backed out several times and retried until I finally gave up. This was on my home wifi. I'll try your work-around for a few days. T-Mobile version.
EDIT: This may be just a FlipBoard quirk.

I will try this when I get home. I have a problem on my Sprint SGS3 where it stays connected to wifi but the internet won't actually work (can't browse internet, use play store or youtube, etc). Wifi never sleeps, it's always on. It never disconnects from the network, it just stops receiving and sending data. So we'll see if this does anything for it.

you guys dont have an issue where the display doesnt timeout after turning off the power save?

display won't time out from turning off the wifi power save. Totally unrelated. I am trying to mimic the problem right now.
If anyone is having the issues of the reconnnecting every few seconds and can logcat it for me, PM me please. I can't seem to mimic the problem since the fix.

Turning off power save does indeed fix the WiFi issue at work. As posted before, restarting the phone turns power save back on and the problem is back.

PM sent.

Going through multiple logcats now.
I am seeing even with power saving on though, the problem is still there. It is still disconnecting from WIFI and going back to the data network.
I am sifting through ALOT of code, as some of these log cats are extremely long.
Give me til tonight and I should have a reason at least to why it's doing it by comparing on vs off on powersave.
I have a request, anyone WITHOUT this issue, can you send me a logcat with your WIFI turned on?

Thanks for this. I was about to return the phone because I kept losing ability to connect to any WAPs after sleep mode kicked in. Mine is a Verizon S3.

I've seen this as well. Almost always after deep sleep. Most of the time I have to cycle Wifi to get it connected again every so once in awhile it will connect again on its own. Regardless of the settings that I put in "advanced" under wifi it will do this. Even if I have it set to keep alive never, always or plugged in it doesn't matter.

I still need a logcat from someone NOT having these issues.
Right now from looking through over 10 logcats, I am seeing that it's usually happening on routers that are encrypted with WEP and WPA, unfortunately the 2 most popular forms of wireless security.
That being said, users that are on 'open' networks do not seem to be losing access.
2 things.
1. Can someone PM me a logcat of them successfully connecting to wifi and NOT having drops. I don't care how long the logcat is.
2. When you post about your problems, please tell me what carrier and what type of encryption is being used on the router (if any)
I have been comparing and in each instance, WIFI is going into sleep, turning on data, and then having a problem turning back on.
I think it's an attempt to save power, but only it is not because switching from WIFI to data back to WIFI so much is a real drainer.
Still working on maybe disabling the power save by using a init.d script, to prevent power save mode from coming back on when rebooted, because I know alot of users are saying after disabling it, it is just reapplying on reboot.
BACK TO LOGCATS FOR ME. :/

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:

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?

Anyone have an issue where you cant turn wifi on after awhile?
