If my evo 3d is connected to wifi, does 3g automatically turn off? and can I receive calls/texts over wifi?
If wifi is in use, 3G gets disabled (atleast that's how mine is). And you can't receive calls and texts via wifi but you will still receive them with your cell's radio (not 3G though)

But your phone will activate the 3G radio in order to send or receive MMS. MMS does not send or receive over WiFi regardless of circumstances.
Does WiFi or 3g use more battery?

3g uses more
3G is only data not phone service. Meaning u can still receive sms and phone calls if 3G is turned off.

If you actually watch your notification bar, 3g turns on momentarily for the mms send and receive

It's all automatic. In order of power usage (highest to lowest)
4G -> 3G -> Wifi
You don't have to manually turn off 3G; the phone puts it to sleep when you go to either 4G or Wifi, and only turns it on if and when you need it. Again, it's all automatic.

Yeah u can turn it off and still receive text and calls. Like right now I'm on WiFi with mobile network off.
Turning it off when u do not need data will save battery also.

If at night I just turn off mobile network, then nothing will sync right? Then I don't have to mess with turning background data off and on. And I'll still get texts and calls

Right. As long as wifi is disabled as well then nothing will sync. And you will still get calls and texts.

You don't have to do anything! 3G goes to sleep as soon as you connect to a Wifi network. Turning off Mobile Network just adds an extra step to your routine.

actually on most phones it will drop to "1X" because it doesnt use wifi or 3G. it will still say "3G" if data is turned on in some cases because that is the way the software programmers intended it to be. if no data or wifi it can still send a text because it uses a different type of data transfer than when you are browsing the internet or doing any other type of data transfer.
thats the way i understand it and i think im right. please correct me if im wrong.
Happy Flashing! (oh wait, this isn't the 4g forum)

I wish mine would, Ill totally forget that I have wifi on and my mms messages wont send until I disable it....which is a pain in the ass when you are uin hurry or totally forget its on,....
Hey guys, (Did extensive search before posting this)
Whenever I get a MMS the messages show a download button but will not download. I have tried turning wifi on and off, turning mobile data on and off, rebooting, using stock app and Go SMS and nothing is working. I looked in APN settings but do not know if they are right or not.
The issue just started recently, I have had the phone about a week and they seemed to work at first.
Please help,
This is driving me crazy and is frankly unacceptable in 2012. I saw some threads about old Galaxys having this issue.
You have to be on mobile data without wifi for them to download.

Thanks for the reply, but I have tried turning wi fi off, which in turn reverts to mobile data and still no success. Could it be that I also use a micro cell? My carrier service is literally the worst possible at my house without the micro cell. This is quite unfortunate if so.
I think wifi has to be off when it is initially coming through and yes, a micro cell will do it. Is it a voice micro cell or data?
Sent from my GT-I9300 using Tapatalk 2
Its a voice micro cell, but it also transmits a 3G signal. Not sure of the speed since I always use wi fi.
This is boggling my mind. Are you telling me that it is not possible to recieve a freaking MMS message created in 1982 (sarcastic) on a 2012 LTE device if I am in a wifi network. WTH. That is crazy to me.
So are these images gone or do I need to turn off wifi and turn off the micro cell to download?
Thanks for your help btw.
So I disconnected wifi and disconnected my microcell and clicked download on Go SMS and nothing, error message. Pulled up the stock SMS app and clicked download and after a half minute or so the picture appears. The picture then also shows in Go SMS.
I guess the solution is no MMS while at home which is a bit frustrating coming from another device/platform where this problem would not occur.
Thanks again.
I have the international GS3 on AT&T. My phone automatically downloads MMS if only mobile data is on or both wifi & mobile data are on. I believe it is your microcell causing your disruption OP.
Sorry, my international S3 also only downloads MMS if only mobile data is on.. I have yet to see it auto download when Wi-Fi was on. I would say it could be the microcell in this case though.

When mms comes in the WiFi should temporarily shut off and the radio picks up 3 or 4g in order to download it. U honestly won't notice any seperation. If u honestly can't receive them, check your apn settings
Sent from my vivow using Tapatalk 2
You are getting mms when you are away from your home/microcell, correct?
hmm, i just noticed that mine has been doing this lately too. MMS won't download unless I turn off wi-fi. I'm on t-mobile
I am having a problem where any time I turn my wife on, my mobile data turns off (no 4G or 3g icon, also network signal info app shows no data). Is this a designed feature or is it a bug? Running stock Rogers firmware I747MVLLE8.

Well that's your problem bud. You're turning your wife on, not the wifi But on a serious note, this is an intended feature of android. When you turn on wifi it turns off mobile data to save your mobile data. If you dont mind me asking, why do you want your 4G to stay put if you are on wifi?

Avoid showering. Your wife won't get turned on as often. Problem solved.
Sorry. Couldn't resist the auto-correct fail... If you're on wifi, your 4g/3g automatically shuts off. That's normal.

Alright thanks guys. Is there any way to turn this feature off? I want to keep mobile data on because I have really bad service at my house and I am trying to analyse it a bit.
You can just turn wifi off. You can't be connected to 2 data sources at the same time (that isn't an android thing). If wifi is off, you'll connect using 3g/4g instead.

I can understand that. Seeing as how we don't have root yet, I cannot tell you in-depth way around to reset app and wifi calling. Only way I can think is that app has faulty install or something obviously broke in running. For temp, have you restarted the device then tried? How good is location/satellite service (GPS only, battery saver)? If so, I would recommend (sadly) a factory reset and redo the wifi calling. If something still broke and error still persists, then maybe faulty hardware at this point. I had to factory reset first day I got it due to issue with brightness not sensing correctly. Everything works now. Ill keep looking at it but for now, only way is through restriction by phone not root yet.
That's the thing haha to have a solution before I have to FR the device. GPS is good in this area maybe is address...

I know, no root limits answers we can give obviously haha. Try address but I don't think that would cause FC in location query. The app should have just told you no good, not FC. That's why I can see this is frustrating haha. I have no FC and could not reproduce by wrong address and such. Ill keep looking.
Yeah that's exactly how I feel... Frustrated. FC every time when authenticating

Sorry to hear. That's all I got now since no root to edit other files. I'd just try another wifi if you can and see if it happens again. If so, no dice, sounds like FR to resolve only way.
I'll be doing some changes like moving from this area to see if it is the gps or the hardware. The last thing I'll do is the reset tho.

I am wondering the same thing. That notification drives me crazy. I seem to be having issues receiving some calls. For some reason the phone will ring in wifi calling and show who is calling but no one is there one I answer. The other person tells me it rings but then goes straight to voice mail.

It is real annoying when it happens. I shut it off for now because I didn't really need it on. I get pretty good signal but it seems to be in and out at work sometimes so I liked having it on. But it does me no good if almost every call I get does that. I assume they are working out the bugs in it.

WiFi calling works fine for me but not for texting. Ill have to retry to send the text a few times before it goes through. Also my mobile signal drops to no bars when WiFi is on, and returns when i turn it off.

Yup. I used wifi calling all day yesterday... It definitely helps when making a call.. But i lose all my bars and cannot receive calls. I confirmed this and had my wife try calling me with different configurations in different parts of the house. I've posted on the sprint forums to see what word I can get on this...

I just posted in your thread. Maybe it will speed up the response if they see two of us with the same problem.
how did yall get WiFI calling? my G Flex had it in its last update tho i never used it, but i am on the ZV4 update, yet i do not have the WiFi toggle. any ideas why?
So, I'm running OC5 OTA update, rooted of course, and have Hotspot working with the APN dun addition (not Galaxy Tools). Is there any way to keep Hotspot from turning itself off when I get a call while on a 3G network? Id like to keep it running until I choose to turn it off, regardless of the state of mobile data. See attached screenshot.
Thanks in advance!

Looks like it's not letting me attach my screenshot. See it here: https://www.dropbox.com/sc/73ot1zhyjhtnvrs/AABxxLdUh2USUIpwIddj3c0Ra

This. Only lte and Wi-Fi does your connection remain on, on 3G it disconnects.
Sent from my SM-N900P using XDA Free mobile app
Maybe I'm being misunderstood. I know data and voice don't work at the same time on 3G. I want the Hotspot to remain on, even without a data connection so the clients that are connected don't lose their connection to each other. Yes, I realize that they cannot connect to the interwebs but I use the Wifi AP to stream Plex from one device to another and it's a pain to reconnect and start the stream over. My kids also use it to play games together on their iPads.
Sorry for the misunderstanding.

My understanding is that if the data connection is lost, then hotspot turns off by itself. I'm not sure if I've ever seen any way to change this.
One thing you could do is use tasker or automate it to setup rules to turn it back on when your phone call has ended.

I'll give that a try. I don't recall it being that way prior to LP or on my S4. Oh well, thanks for the suggestion!
