Auto-switch between wifi and 3g - Galaxy S II Q&A, Help & Troubleshooting

Does your connection auto-switch between wifi and 3g?
I was out earlier and the wifi was still locked onto to my home network yet I was no where near home. I wasn't able to browse etc as there was obviously no connectivity. I would have expected it to switch over to 3g or H.

Anything I might be doing wrong? Or settings that may need tweaking?

Could it be down to the fact that I have gps turned off so phone cannot track position? Do you leave this on permanently and if so what's the battery drain like with it on?
Let's get some response on this please. I would like to determine if I have a faulty device and whether I need to start arranging a return.
Thanks

I have GPS on, but it doesn't use any battery unless an app tries to use it. But I don't think this has anything to do with your issue. There aren't any settings that I've changed. Try a reboot.

Y5 Saver
There's a very good app called Y5 Saver - https://market.android.com/details?id=pl.polidea.y5 which autoturns your wifi on/off depending whether your in the proximity of the wifi router (uses network triangulation).
Only issue is that it seems to override 'airplane mode'.

More information plese. What rom, kernel, modem? So you turned both off, and when you lock your phone, both turns on automatically? Do you have installed some app which manages connections, eg juice defender?

Location issues

Anybody else having issues getting location? Maps and other apps aren't getting location. I can get GPS now and then but only in the very open. Seems like I can't get agps or network location.

I get a GPS lock in my living room within 5 seconds. No issues at all getting location.
Hmmm wonder why I'm having issues then

I had location nailed down before the map loaded <2-3 seconds. I am also on WiFi at my parents house.
Under settings>location I have all the boxes checked.

Have you reboot the phone today?
So I unchecked all 3, rebooted and then checked them all. All looks good now.
Thanks guys!!

I can't get the weather to find my location I think I have a bad GPS chip I've tried resetting and everything but if I go to Verizon to switch it out I hope they don't try to get rid of my unlimited data

I did something similar and all of a sudden after a reboot it asked for permissions to use my Google account. After that everything has been working peachy.

My question is why is this the only phone where you can't turn off the gps its always running and no line goes through it

If you mean the icon next to your 4g icon, that isn't the GPS icon. That reticle stays there and does nothing.
GPS failing during Strava
When I start a Strava OR Endomondo cycling tracking the GPS seems to stop tracking during the ride. If I wake the phone to read a text or something it seems to come back. Is it possible it is being put to sleep by OS or Sense even though the app is still asking for data through the API? Otherwise it locks quickly and works as intended.

google maps and battery drain while not in use

after the maps update a couple months ago I noticed it keeping my phone awake with partial wake-locks and firing up GPS, wifi, and wireless location services while my phone is asleep. I have location services set to *not* collect anonymous location data so I'm puzzled why it's doing this. anyone else notice this? any solutions?
Go to maps press menu settings location and look at this:
Make sure it is all off.

Also, go to Settings, General, Location services, and UnCheck Google's location service and Location & Google search. I do allow GPS satellites though. I fully charged my phone (lgog) and unplugged it before going to sleep, this morning when I woke up, battery was at 98%. I am running nottach's base ROM 0.7.3 with fast dormancy disabled.

Oh yeah, been there, done that. Back in the day the forced latitude stuff was killer....

I've just turned off the wireless networks one so only gps is enabled. I'll see if that makes a difference. Just knowing you guys aren't having problems is very helpful. Thanks.

Also, if you added Google Now, go turn that off in settings. That app polls location, weather, news, etc. I lost as average of 45min to 1 hour on my Galaxy Nexus and the only change was GNow

I'm missing something simple. I don't get those options when I'm in maps and go settings-location settings. I get a white screen with a map saying I haven't turned on latitude/location sharing. Do I not get your black menu because i don't have it enabled? Is not sharing the same as sharing and then turning everything off?

Wifi keeps turning on

I've searched and the similar threads seem different and don't work with this phone. I turn off Wifi and not long after its on again. I've gone into the Wifi settings and turned everything relevant off but it's still happening. Anyone know wtf?

Sounds like Connection optimizer is on.

Are you rooted? I was on frezza's beast mode kernel, all versions seemed to not allow wifi to shut off. Also had problems staying connected to my home wifi. Now I'm not saying the kernel is the problem but when I restored the stock kernel everything works again. Haven't posted in the developers forum but also haven't seen anyone in there with the same issue.

Yep, go to Settings > Connections tab > More networks > Mobile networks > Connections optimizer to turn it off.

Stop auto connecting to WiFi networks

Sometimes when I leave home I forget to turn my WiFi off and it keeps connecting to any open networks wherever i go. I went into the WiFi settings and there are only a few options there and I tried all different combos but i still keep auto connecting. What am I missing?

Under WiFi settings, goto Advanced, and uncheck "Scanning Always Available", by default this is on, even when WiFi is off.

I think I misunderstood your question...if it's actually connecting to the network, it's because at some point you've connected to it before and it's a saved network. Next time it connects to it, go to WiFi settings and forget the network.
