So I noticed on my old S5 that if I was on WiFi and enabled WiFi calling, the cellular signal actually disabled. This helped the battery a decent amount as it's one less radio on.
My S7 seems to keep the radio active still, anyone else notice that?
I know once VoLTE rolls out (yea funny I know lol) that this will almost be required (unless they make it smart enough to only enable when WiFi signal getting low) that way a hand-off can occur but makes no sense right now for it to function how it does. All it results in is eating more battery. The S5 method was kinda smart.
Also noticed that the newer phones don't seem to add the "feature" code visible on sprint.com that the old ones use to for WiFi calling.

I had been having problems getting 4G at home and just noticed that if I turn off WiFi, 4G pops right up and as soon as I re-enable WiFi (which connects to my home network) 4G disconnects. Has anyone seen this behavior? When you think about it, it makes perfect sense, and since both are enabled to connect when the other one isn't, the flip-flop is automatic. But it surprised me.
its probably because sprints 4G is based on WIFI. or it just cuts off 4G cus you dont need it anymore
I believe it works the same way as WiFi and EVDO works on older phones. When you turn on WiFi it will use that as your data connection instead of EVDO regardless if it is a crappy WiFi connection.

Yeah, it's actually pretty cool, but if you don't know about it, it gets frustrating. I called Sprint customer service and he had me go through the battery out/in routine and go outside and try, etc. So maybe they don't know about it either!
But it makes sense for Sprint, since their data plan is unlimited and they want to avoid network overloading (are you listening AT&T? LOL). The only thing you miss on WiFi are location-based sevices that rely on GPS (navigation, some weather products, etc.).

WiFi and 802.16e aren't all that similar. LOTS of differences between the protocols.
Maybe there's some isolation problems on your device as Sprint is using their 2.5 GHz spectrum holdings for their 4G network.
4g network and 3g network both will shut off when enabling wifi. Why have 2 forms of data going at the same time? Its not gunna use both to double your speeds.
You wont lose any GPS features. Turn on wifi and load up Google Maps, it will find your location exact.
When making calls and sending text it uses 1x so you will still receive everything except for MMS. Maybe they fixed it to where you can receive them even when on wifi with the Evo, not 100% sure.
4g and WiFi are both data only connections. You don't need two data connections simultaneously so it is smart enough to auto disable one to save battery. It would also cause routing problems.
Every phone does this LOL When you switch on Wifi they turn off 2g,3g,4g etc because you can't use 2 data connections at the same time.
I'm curious why you would want 4g and wifi on at the same time?
I thought this was pretty common knowledge (on any Android phone)... And I also thought it was done for battery conservation reasons as much as anything else. WiFi's a simpler point to point connection and from what I understand it sucks less power than 3G or 4G which is constantly checking for additional cell towers in case you've moved, etc.
If you're at home or at work w/a stable WiFi connection you should be able to preserve more battery power by using it, within the settings you can even set it so the phone doesn't revert to 3G when it goes to sleep (the default setting IIRC), otherwise it does this and only jumps back to WiFi when you wake it ('till you're out of range anyway).
I agree with all the comments. And if the Sprint Customer Service guys had said, "Hey, you idiot...it's supposed to do that," then I wouldn't have posted. But the fact that he was as stumped as I was prompted me to post (we all know that Sprint gets all it's info from reading these forums...LOL).
Sorry if this is common knowledge and I'm just sllloooowww....but I have discovered something with my EVO that was driving me nuts!
When you connect to a WiFi network the phone will automatically drop your other data connections (3G or 4G). If you are connected to WiFi and turn on 4G the phone will not connect to 4G and instead will show a status similar to this:
turning on->scanning->disconnected
or
turning on->scanning->connecting to spring ->getting IP address -> connected ->disconnected
All of this was quite irritating when I was assuming that my 4G wasn't working properly. It was pretty embarrassing to learn (through many trials and errors) that I hadn't correctly associated the 4G connection 'issues' with the presence of a WiFi connection.
Hopefully some of you who are experiencing 4G 'issues' are just suffering from this same ignorance.
P.S Please don't take this as an opportunity to rip on myself or others for being ignorant, thank you.
Thank you for taking the time to right this up. I would have thought this to be common knowledge, but I can see how the cycling of 4g connect disconnect could be confusing.
It will always drop the current connection if you switch it, doesn't matter which carrier you're on. reason you can't connect to 4g (aka WiMax) while on wifi is because they are using the same frequency 802.11. the only difference is that wimax is on 802.11E where as the wifi on the evo can go 802.11B,G,N

Wimax uses the 802.16 protocol which is seperate completely from wifi.

I'm not sure why they are disabled when wifi is on but my guess is to conserve battery or avoid confusion with data connectivity such as flipping back and forth between radios. Who knows why heh

Heh, well once I realized what it was doing it became pretty obvious why they were doing it.
There's no need to keep more than one data connection up on the phone, and obviously the less data that flows over sprint's (or any carrier) airwaves the better for them. When WiFi is connected, it makes sense for the phone to shut down the cellular data to reduce network load. Also, I am not positive about 3G vs. WiFi but I am pretty sure WiFi uses considerably less power than WiMax, so it makes sense from a battery conservation perspective too.
This is actually a common practice on smart phones it seems. I confirmed with my brother that this same thing happens on his Moto Droid with Verizon (when WiFi connects, 3G disconnects).

It has more to do with conserving battery life than taking a load off of Sprint's network. BTW, WiFi tends to use a lot less battery than 3G.
Does an unlocked 4g phone work in Italy(on 3g at least)? Wath the difference between protocols(wikipedia is not clear enough)?

Hello Everyone --- Note3, NC2 Leak stock modded deodexed rom.....worked fine for several months.
Cell signal in my basement office is very weak -- got a VZW extender, 3G signal now shows super good strength and calls are good. I am on wifi for data... Problem is when I'm on the extender, the phone is laggy as ever...super slow, gets very warm, screen lags, experience is horrible. I have reflashed, cleared cache, everything.... to no avail. Once i unplug the extender...everything is just fine again (snappy/responsive, better battery life, etc etc)
Anybody else experience this behavior?
Is it a Booster or a microcell? Microcells/femtocells plug in your Home Internet where the boosters try to boost cell signals. Boosters generally only work worth a damn if set up very particular to the scenario at your location. Otherwise they get a ton of echo and your phone can hand off between the tower and booster which can lead to increased power use.
I hate boosters for the most part. They work best if you have virtually zero service indoors and can run a long coax outside to an antenna location that gets good service. Swapping the typically included omni antenna for a directional antenna and aiming it directly at the tower would be of much benefit.
Putting a booster into your house and expecting it to not suck is like expecting to find good food at Mcdonald's.
Also, you may consider that your Note3 may have reception issues that a number of people including me had when upgrading to KK. You should try to verify if the reception seems like it is behaving normally.
Lastly, use the app Advanced Signal Status to force your phone to CDMA auto (PRL). This will allow you prevent your phone from trying to find LTE, which will save battery and will operate cooler.
You can also force CDMA only, which will prevent your phone from connecting to EVDO as well as LTE, and should run cooler and save battery.
Note3 does not have separate radios for simultaneous CDMA data and voice. The ONLY way to have voice and data at the same time is to have 4G or wifi.
In your scenario, I would just put the phone into CDMA only mode at home and use wifi, and put it into CDMA/LTE auto (PRL) or CDMA auto (PRL) depending on whether you want 4G or 3G data while traveling.
Good luck
Is there anything that can be done to improve performance over mobile data? I'm on Verizon and more often than not lately it seems if I'm not on wireless I have intermittent internet access. Voice seems to be ok, but data drops in/out. I don't think it's the carrier because my work phone, same carrier, never seems to have an issue. Even so much that i had to go out of the country the other day and my work phone connected no problem (it was roaming, but still), while my 6p never was able to connect to the mobile network, only to wireless. I'm on the latest build so I imagine my radios should be at the latest as well. I have a case on the phone if it makes a difference, but it's a relatively thin Spigen case, not a monster that might impact performance.
Hey all so I just got the 6t and I use Verizon and noticed that there is no option for WiFi calling. I guess after searching around Verizon needs to enable it? But I'm just confused as to what needs to be done to allow users to use it.
It's a big deal for me because the reception in my house is bad. I have thick walls (wooden log cabin). On past phones my phone's would drop lte to 3g then back a lot and only way around this was to use wifi calling.
To hold me over I just dumped 200 bucks on a lte externder from Verizon (femto cell) but I thought I would ask what needs to happen for Verizon users to get wifi calling and if it would ever come down the road
I would love to know the same info for AT&T
I tried all the modules and tricks to get it working and never could. I had all settings enabled in the hidden menus and by all appearances it should have worked but it never did. I ended up returning the phone because I don't have a good LTE signal at work or my house. Loved the phone otherwise but not getting texts and phone calls was a no go.
