T-mobile S7 edge.
This doesn't always happens, but it happens often enough that it's beginning to get frustrating. When I'm connected to WiFi for long periods of time (at work/home), then leave to an area that has full LTE coverage, the s7 edge will not connect. I get the signal bars, they're usually always full, but no '4G LTE' logo. If I open any app/browser, it claims it's not connected to the interwebz. If I put it into airplane mode, then come back out, it'll grab full 4G LTE again and work fine.
Not sure if I have some settings screwed up or if i'm overlooking something... or maybe it's just a bug.
WiFi calling enabled, set to prefer WiFi networks.
Smart Network Switch disabled.
Aggressive WiFi/cell handover disabled.
Wifi roaming scans disabled.
Keep mobile data turned on enabled.

I have the Wifi enabled on my Droid Charge so when I'm home it will use the Wifi. But when using the Wifi the 'mobile data' icon is still highlighted in the pull down tasks..
now is it trying to use BOTH the wifi AND the mobile data at the same time? I want to use ONLY wifi at home to help conserve battery usage.
then when I leave my house will it automatically turn wifi OFF and use only mobile data?
trying to keep the battery usuage as efficient as possible.
In theory thats how it's supposed to work.
hahahha in theory.. but does it actually do it?
and another thing.. in the Mobile Networks Settings.. under 'System Selection'.. you can choose either LTE Automatic or CDMA Mode... being I am ONLY in a 3g area and do NOT have 4g LTE in my area yet.. should I choose the setting for 'CDMA Mode' Will that save the battery? or does the phone try to switch from 4g to 3g...
Yes, that is how it works. If wifi is on, the phone will use wifi by default, regardless of what it is connected to for mobile data (4g, 3g, 1x). Check out http://myresolver.info from your browser to see your ip and dns server you're using.
Ok I've got a few questions about the different network types and battery usage.
As far as I know there are 4 different possible scenarios:
3G mode active
3G mode active and connected to mobile data (3G/H showing in notification bar)
2G mode active
2G mode active and connected to mobile data (E or G showing in notification bar)
Currently I have settings default with "Use only 2G networks" unchecked, and "data enabled" unchecked. I have tasker made to automatically turn mobile data on whenever I open any app that may require it, and then turn it off after the app closes, or I can switch it on from the status bar power control.
This is because I assumed having it constantly activated would consume more power. Is this true? does it consume more power having data enabled even when no traffic is going through? If this wasn't the case, I might as well leave it enabled. However with my current system I could still be saving power because if I leave data on, traffic WOULD periodically be used for automatic sync and apps randomly using network and stuff.
The other thing I was wondering about is if there was any major difference in power consumption between 2G and 3G network modes with no mobile data connected. if 2G uses much less power, I could have it set on 2G by default then use tasker to switch to 3G and activate mobile data when opening any internet requiring app. Are there any other advantages of having 3G active over 2G other than mobile data transfer speeds?
Thanks for any help!
Imho your settings are good. Mobile network is one of the battery killlers, so not using (or better using it when you really it), is very good. You are right, 3g has a higher speed on mobile network. Whereas the 2g-network has a much better network coverage. And the permament switch between 2g and 3g drains the battery very fast, too (happens e.g. when you travel).
To sum it up: Use 2g and mobile network off. If you need to use mobile network, turn 3g and mobile network on. Are you done, turn them off again and switch back to 2g.
When you say mobile network, do you mean when an active data connection is enabled?
Because just by the name 'Mobile network", you can be connected to a mobile network for calling and texting etc. without being connected to mobile internet/data.
Is there a difference in call quality between 3G and 2G networks?
Also when toggling between forced 2G only and 3G there seems to be an inactivity period where the reception icon at the top shows like 'disconnected' like it cuts all network communications, then shortly connects again to the specified network type. This delay might be annoying when trying to get internet fast on apps that need it... might not be worth the power saving, if it is only minimal power saving

for the best battery duration, use GSM ONLY!
Hey guys.
My co-worker has a G2X has well. He'll be traveling to Spain at the end of this month. Would there be a way to use Wifi calling without incurring charges?
From the T-Mobile Cust. Service rep told us we'd need to have the phone on airplane mode ON & Data Roaming Off. If we have the airplane mode ON the Wifi Calling app doesn't let us turn on Wifi Calling. So what can he do not to get any sort of bill increase while he's over there?
Having airplane mode ON obviously will disable wifi calling since it disables EVERYTHING (radio, bt, wifi, etc.).
Log onto wifi, enable wifi calling, place your call. It works overseas like it does here domestically.

Well, if I enable Airplane Mode ON, then I can still go right after and enable Wifi and surf the web with Wifi. It even still shows Airplane Mode as being ON. The thing is that Wifi Calling doesn't like airplane mode on. Err. So What do I need to disable in order not to see any insane charges of the phone roaming onto cell towers, 2G, 3G, 4G, etc?

Turn data roaming off. I use the wifi calling feature from China quite a bit and to avoid crazy bills make sure data roaming stays off and only use the phone when connected to wifi.

Follow this ^^^ and you are golden.
If Data Roaming is turned off, and I go to Canada, will I get an extra charge for incoming text messages?
I used to use Wi-Fi Calling internationally all the time on my G2. In order for it to activate, it has to register on a cell network first. So if you're roaming, you still need to allow the phone to pick up and show connected to the foreign cell network. Then when you activate Wi-Fi calling it disables the cell connection. Make sure you turn Wi-Fi Calling off before disconnecting from Wi-Fi. Otherwise it gets stuck and you won't be able to turn it off and get your cell signal back until you connect to a Wi-Fi signal again.
Some warnings. When first connecting to the foreign carrier's network, make sure the data connections on the phone are disabled. Otherwise the phone will automatically start syncing and T-Mobile's data roaming fees are outlandish. My G2 always disabled the cell signal when Wi-Fi Calling was enabled. I used the G2X once overseas and, because the cell signal indicator still showed active, I wasn't sure that everything I was doing was over Wi-Fi. Have your friend watch for this.
Not entirely true regarding cell network connection.
I've used wifi calling in datacenters with zero cell reception. It registers and enables without needing to connect to anything first.
Very helpful, I'll just disable mobile data all together once I am out of the US!
So data roaming being turned off will solved that. Ok. How about text messages? Will they not come in until he enables Wifi calling or if they come in he'll be charged an insane amount.

If you have a messaging bundle or plan, international messages you receive will be pulled from your bundle. (quote from T-Mobile's website)
So basically, if I have unlimited international texting, and I receive texts while in Canada, I'm good?
Problem is that wifi calling is sensitive to having good wifi signal and it is easy to drop wifi calling without noticing it. And you could be making texts or calls on international roaming rates and not know it.
So, can you turn off cell service some how? Not just data, but voice too? And not airplane mode, because that disables wifi calling. So is there a way to turn off just cell service?

Just completely uncheck roaming and International roaming. Was in the carribean and I never connected to a network.

However, that only works for data roaming? You will still connect to a voice network no matter what. Is there a way to not connect to a roaming voice network?

I didn't connect to one. Under network providers, select only yours. Don't let it choose automatically.

This may be a dumb question but is there a way to set up wifi and data to automatically toggle? As in, when wifi is available it uses wifi, but when its not it automatically switches to 3g/4g? When im home i like to use wifi, but then when I leave I lose it and usually forget to switch over to data, so I get no emails or updates on anything until I look at my phone.
Option 1: Leave wifi and data on all the time.
When a trusted wifi network is available and your phone is connected, your phone will not use data (you will see the data indicator automatically disappear even though it is enabled). When you are no longer connected to wifi, your phone will automatically bring the data connection back.
Exception: using apps (usually Verizon-specific) that require a mobile data connection will bring the 3g/4g radio out of dormancy.
Pro: automatic switching, no need for additional apps.
Con: leaving wifi on takes its toll on battery life.
Option 2: Download/Install Llama from the Market
After you teach the program what cell towers are where, you can define criterion (ie you physically leave or enter a defined area, a certain time, etc) to carry out specific actions, including changing volume, display brightness, toggling data connection, wifi connection, bluetooth, gps, etc.
Pro: automatic switching of most anything imaginable, saves battery life compared to leaving wifi on
Con: additional app running in background, occasional instances of bugs

wi-fi matic is the app you want, it auto toggles wifi on when you are on the same cell tower than is near your home, as soon as your cellular switches to your home cell towers it toggles wifi on, and when it's away from home cell towers it toggles wifi off, you can use it for multiple wifi networks as well, i travel for work so i dont have a work wifi but u could have it auto toggle on at work or home, its also extremely easy to use, far easier than any tasker program.
So, whenever I made a call on my N5, the Wifi gets turned off and it switches into 3G/HSPA+ mode (no LTE). When I end the call, it will connect to LTE and then enable Wireless again and connect like normal. This is on T-Mobile if that means anything.
Is this suppose to happen? Is there a way to prevent it from disabling Wifi during a call?
EDIT: The issue was with Tasker, since I use Cell Towers to tigger Wifi, and I guess calls uses different towers.
Anything? Even when receiving a call, before the call actually "comes through" the Wifi will be turned off; THEN the call comes through.
I just tried calling my ATT phone in a good LTE area with good WIFI. It did not drop wifi. I'm stock non-rooted 4.4.2.
There is a setting in the wifi page which prevents the phone from connecting to poor wifi. Is it possible that you're in a borderline poor wifi area and when a call is received your wifi drops just below that threshold and phone then falls back on 3G/LTE ? I noticed my phone at home when I go far from my AP I get 1 bar on the wifi but the phone says it is connected. But then wehn I try to access a web page, the phone would drop wifi and connect to 3G. I don't have LTE at home so I can't say if it would've connected to LTE straight away after wifi drop off
