2G/3G Toggle?

Any idea how to enable/unhide this feature under wireless networks? Switching to 2G only nearly doubles my battery life on my Nexus

I've just been accessing the band selection menu and selecting gsm bands only. The menu is *#*#2263#*#*. This little "fix" doesn't hold after a reboot, fyi.
I also use the SMODA widget to shut off the data connection whenever I don't need it.
It sucks that mobile data is always on by default, with no stock option to shut it off, and that you can't select to only use 2g right out of the box.

I've seen some widgets that will turn 3G off/on... I wonder if those work on the captivate. I'll give it a try today.

I think you should be able to force it by going to *#*#4636*#*# and selecting GSM only, but that's such a hassle

See if this helps do what you want.

Try quick settings from the market and toggle the APN control on and off. Appears to work....

I'm not looking to completely disable data - I just want to be able to disable 3G when I don't need it (and revert to EDGE data)

The widget I have - which comes with Weather and Toggle Widget - does not work. It just brings up the wireless connections menu, but of course you can't turn it off from there.

I'm using smart bar, and it has a 3g-2g switch, but it isn't working. Since this functionality isn't working on my captivate, but worked on my other phones, I'd say it's been intentionally pushed out. If a hack can fix this, I'd love to learn about it.

I am also interested in this. I work in.a area that switches from edge to 3g a lot and when i had a iphone i increased my battery a lot by setting it strictly to edge at work.

After all the digging and searching around, I found two apps that work perfectly on Samsung Captivate for toggling mobile data (3G)
- Juicedefender (it has a widget you can use to toggle 3G quickly)
- SMODA Widget (It doesnt have too many 5 star ratings but works fine on my samsung captivate).
My phone is rooted but I believe it is not a requirement of either of the above apps. Hope this info is useful for other captivate owners.
Most of the other APN / 3G toggle apps on the market try to put a suffix on the APN names in settings. On the samsung captivate this works only with a restart/reboot. Meaning if you disable 3G using the app it would put a suffix like 'disabled' or something to the APN name. But your phone still has the 3G connection using the original APN settings. Only after you restart the phone does it see the 'disabled' APN name and is not able to use and hence no 3G. Vice versa when you want to enable 3G back - needs restart.
I dont know what process the above 2 apps use but they work instantly on my samsung captivate. No need to restart or click a bunch of other settings. They work perfectly and as simple as it should be.

i heard juice defender works well

Where are you seeing the option to switch from 3G to EDGE? I just installed Juice defender but can't find the option. The mobile data connection widget just shuts off my data entirely.

Sorta on topic but when I try to install juice defender it is never able to install the aosp helper. Does it work for you guys?

Yea, I was hoping someone maybe knew which file you had to edit to reenable that option in the network settings page

I already have Juice Defender I know I can disable data completely, but I'm looking for something that can disable 3G while keeping EDGE alive

It says install completed, but in the logs, it says there was an error

It would be nice to disable 3g while at home or something , where the reception is a bit sketchy, but i could at least still use it for voice and texting , and use wifi for the internet and app stuff. Could help conserve battery life as well

I tried smoda and can confirm that it doesn't work for me. It disabled data completely as I cannot access the web.when I activated the widget. It would be nice if we could set this phone to 2g and if data speeds were above a certain threshold for a certain amount of time then we could have it switch to 3g.

Yeah, I'd really just like to force the phone into EDGE mode when I'm not using it - updating weather and fetching e-mails are really not that data intensive and don't need the speed from the 3G connection. I'd like to have a widget that will turn the 3G back on when I'm on breaks or whatever and want to surf the web, watch a video on YouTube, whatever. I believe you can do this in the service menus, so you would think there would be a way to accomplish it with a widget - even if it were Galaxy S specific.
I'd pitch in 5 bucks towards a bounty towards such a widget if somebody could create one.
Juice defender does have the option to run the 3G radio on 15/1 cycles (off for 15 minutes, on for one) but I'm not sure how/if my apps that would use background data would sync up with that.

i9000 vs 1897 band settings?
Now that I've moved to the JH2 firmware I'm back to some of the AT&T crap, like hiding the band selection setting.
I'm thinking that the differences are in the Settings.apk.
Others have said that since it's a system app and signed, you can't just install it. So I'm wondering if it would be possible to pull the Settings.apk from the i9000 rom and stuff it using the update.zip method.
May have to do a backup and give it a shot.
Once that setting is available, you can use 2G 3G switcher from Market to bring up the UI and toggle between EDGE and HSDPA.
By keeping it on EDGE, my battery lasts alot longer...

If we could manage to enable it juice defender would switch back and forth automatically based on download speed and/or the screen being on/off, which be ideal.

Change 3G to 2G automatically when screen off?

Hi!
I can't find a single widget/app that is able to change between 2G and 3G with one click, you're always taken to the menu only. Doesn't android allow this function?
I would especially like a function to change to 2G automatically when screen is off. Can anybody explain to me why this isn't possible or if there actually is a program?
Cheers

Have you tried juicedefender? ... it does the auto 2g function you describe.

Juicedefender can disable data connection when screen goes off.
It is not the same as switching from 3G to 2G.
... Anyway I am using Juicedefender to avoid several syncs when the screen is off.

Well yes i used juicedefender, but that's not what i'm looking for. Right now i use data on demand, which does its job flawlessly. But i still have the feeling that my phone eats more battery on standby when i've got 3g enabled. Maybe it's just placebo, who knows?
I just don't understand why it isn't possible to switch between 2g and 3g in the same way you can turn BT and wi-fi on and off.
But anyway, thanks for your advice guys!

[Q] HTC HD2 - how to Stop 3g

Hi all, please help.
I've got a HTC HD2 that wont stop connecting to 3g. I've tried setting it to 'my work network, but it still keeps connecting. Also tried new modem connection to 'offline', it says that already exists, but I can't select it.
It doesn't cost much, but each time it's a few 'p', once added up it can amount to £1 a day easily.
Is there another way to stop it?
Any thoughts?

Hi there,
I assume your still using winmo 6.5 by the sounds of it
Two simple ways i would recommend, download a free app found in XDA (advanced config (v3.3 i think)) as there is a setting to turn off data there.
or
More simply, go into your apn settings and remove/change the apn name; so for mine i would change "internet" and just remove the t of it.
Can use data if the settings are wrong so it never connects
Cheers.

Yes, am using wm 6.5. Thanks for the quick reply.
Where are the 'apn' settings?
I'm not very savvy when it comes to changing things.

[Bug-Fix] Solution for wifi-shutdown in standby (no root required)

UPDATE: There is an app in the play store called 'Advanced Wifi Lock (Free)' which fixes this problem and DOES NOT need root

ossy1337 said:
Some (or maybe the most) users reported that the phone loses wifi signal after a few minutes in standby. I probably found a way to fix this. All you need to do is:
5. change the line 'gEnableSuspend=3' to 'gEnableSuspent=1'
PS: Keep in mind that unlocking the bootloader using htcdev will most likely void or at least constrain your warranty

Are you sure about the gEnableSuspenT (changing d to t)?

Update in post 1, no root required!

Yeah I found out about the wifi lock issue when I got my sony tablet, advanced wifi lock is the perfect solution!

for me the wifi lock causes very low standby hours. anyone having the same issue?

If I did not misunderstand what you mean by WiFi shutdown, there is an option in WiFi setting which keeps WiFi on even phone is in sleep mode (standby).
Go to:
WiFi list, menu, advanced, keep WiFi on during sleep, select always.
No 3rd party app needed.

That's exactly why this thread exist...
the 'keep on' function doesn't work for some users.

OK, if that's the case, ignore my post then, but I did not really see any where mentioning the "keep one" function not working in this thread, so had no idea... maybe good to add it somewhere just to avoid further confusion
By the way, the "keep on" function works fine for me, so maybe something to do with the router? or wifi band (802.11a/b/n)?

Have been looking for this solution awhile... finally found something that is useful!!! Thanks a lot!!!

This app causes massive battery drain. For me, I updated my device with ics ruu and this problem was gone, but a week ago when I did a factory reset the problem reappeared.

Thanks for sharing. I would've tried it out if it weren't for the fact that my current rom has no problems with wifi connectivity at all.
However, I will keep this app in mind just in case .

Mobile Hotspot disabled? Need help

So, not sure why but I used to use mobile hotspot frequently. Recently, I go in and enable it. It turns on fine? But than I go click on hotspot settings where you can change password and stuff, it force closes.
Though when I turn it on, my pc or anything else can see it, but it has a password that I never set. What's the default password for hotspot??
Now another problem. When I go into app manager, and look for mobile hotspot, its disabled. I click it, and I can't enable it. Everything is grayed out!
What's the deal! How do I fix all this?
Sent from my HTC VLE_U using xda app-developers app

I guess you already did that but what happens if you disable hotspot, then try to go to settings to change password ? Because if everything is okay you can't go to settings if hostpot is enabled, you have to disable it before.
