Connect to 4G during a call? - EVO 4G General

is it a limitation of the CDMA network or software on the EVO that you cannot connect to Wimax/4G during a call like you can with wifi?
Sprints answer to simo data/voice is to use 4G, but if you lose 4G signal while on a call it doesn't reconnect until you end your call. i wonder if that is a software limitation somewhere? radio/wimax firmware maybe?
I know HTC just released the kernel source, but this seems to be more of a radio firmware issue than hardware.

1xrtt calls coming in while surfing

is there any way to make it so if im on 1xrtt and surfing a call can come in?
Calls override data.
Sometime this year, Sprint is supposed to upgrade to 1x Advanced. So once that's done and one uses a phone capable of 1x Advance, you'll be able to surf and be on a call at the same time. Sorry to say, the Epic is not a 1x Advance phone.
Right now the only way to do that is use wifi for data or 4g for data..
if they upgrade to SVDO in the future you can do both as mentioned above...
no i meant when i am on 1x and actively surfing no calls coming ie i miss calls. is there a way to prioritize calls overriding an activate data stream?
No. There is no way to change this. That's the nature of the current 1xRTT implementation. I think this is done at the tower, and not on the phone.
I miss calls a lot when I have bluetooth on and listen to pandora/slacker.. I think the phone gets confused, too many radios active.
How do you all.even know you are in the 1xrtt network and.not 3g?

I've gotten many calls while surfing the web, even text messages come in. They did recently just upgrade my service at my house, though. (If it is a tower possibility.)

[Q] Not using wifi?

In my work developing an App for localized radar information, I find that when I need information from the internet, my phone doesnt use the wifi, but relys on data usage. My house's wifi is unsecured, and my phone is always connected when in range, but where I do my developing in the house there is scant 3g coverage and mostly Edge coverage. (Kinda inbetween towers where I live)
For example, my Weatherbug App will not load (and sometimes lock up) unless the signal indicator says H or 3G or 4G, while being connected to wifi.
I am new to mobile OS so is there something I am doing wrong or something I have not set on the phone?
I have a very weak signal in my apartment. My phone constantly bounces between no signal and 1 or 2 bars. I find that my DVP works much better when I manually turn off the data connection in the Cellular settings when I want to use wifi as my primary connection.
Your DVP says H or 4G? If so, you have soemhing the rest of us do not..
Sent from my Venue Pro using XDA Windows Phone 7 App
Yeah my carrier put a 4g sim into my DVP and upgraded the radio...Works too, I didnt believe it when I first heard it.
i call shenanigans.
if there was a way to screen cap i would show you...but i do not know of any way thus far.
speaking of which, what radio version do you guys have? I got radio software 2.2.50.18, is that any different?

I have that same radio in my at&t dvp. Bottom line is that the phone does not ship with a 4g capable radio. No SIM card changes that fact. Don't let the goons at the phone store fool you.

I agree. DVP is not 4G capable.
hey they offered a free upgrade and I took it...but I havent been able to connect to a 4g network so maybe they WERE fooling me....either way the Wifi issue has been solved so no more discussion on this if you would please.
who faced the same?

[Q] Issue : no Data connection during phone call with LG G2

hello,
i'm using the following version of the LG G2 ;
Android Version : 4.4.2
Band base: M8974-AAAANAZM-1.0.190084
kernel Version : 3.4.0
Build Number :KOT491.D80220a
Sofware Version : D80220a-HKG-XX
and each time i'm having a phone call, i'm loosing the Data Connection (3G or 3G+ or Edge )
What would you recommend to fix this (annoying because i can't use waze for example while having a phone call with bluetooth in my car)
Many thanks for your help

Err .. That's normal, and I'm pretty sure it happens with almost all phones and network providers. Your Data Connection will cut out if you make or receive a phone call. Nohting to do with your phone. Use wifi if you want to maintain a connection.

I think any phone with 2 radios can do it just fine. I'm not sure I've tried with the g2, but my gnex and even thunderbolt could, both on vzw. att phones had this ability for years before lte (and the second radio it required) provided it for Verizon. att even ran iPhone commercials pointing this out, since the 3g vzw iPhone only had one radio and couldn't talk and use data simultaneously.

Yeah I agree, a second radio would be required .. which could be why it worked with your Sensation. Unfortunately I don't think any phones over here in the UK have 2 radios as I have had this issues wih ALL of my phones. It's the norm over here.

I believe, but may be mistaken, that the VZW, ATT, and TMo flavors all have 2 radios while the Sprint G2 does not, as their new Spark network combines voice and data onto one radio. This is what I've gathered from reading other forums but have no concrete proof. I believe I once talked on my G2 while using the GPS when driving, which would obviously require data.
What provider is the OP on? Looks like he has a D802, which is the INT model, right?
...this is normal behavior but only in 2G (Edge)...

It is normal in 2G (GPRS or EDGE) to loose data connection during a call...this is the GSM standard...3G is a different standard, it supposed to keep the data connection during a call - voice data is CS (circuit switch, a GSM stadard call), data connection is PS (packet switch, different circuit in phone).
All 3G phones have similar build so CS and PS are completely separate - if you are still losing data connection during a call could be a network issue, not a phone issue.
In 4G is a different situation, at least for the moment - this is still in development, the voice is still in 2G or 3G, not in 4G.

Sprints LTE on phones prior to tri-band had no issues with simultaneous data/calls. The implementation of these tri-band phones has changed the protocol used. They now use CSFB (circuit switched fallback) and this requires the phone to fallback from LTE when a call is made or received. This prevents any data to transmit during a call.

I know, I red about on the net - as I am living in Europe I don't have this problem - from the begining the European providers used CSFB and eCSFB (they are trying now to develop VoLTE, this is the next step) - I was talking about VOLDOR issue - he mentioned about some problems in 2G and 3G, not in LTE...on another hand he has a GSM+LTE version of the phone, not CDMA+LTE (Sprint) - Sofware Version : D80220a-HKG-XX (Hong Kong - http://www.lg.com/hk_en/mobile-phones/lg-D802)
Sorry, but i'm still a bit lost : Am i having the issue because i have an Hong Kong Version of the phone ? is it an hardware limitation ? Should i try a Europeean ROM Version (i'm living in France, and without changing of provider it was working on my previous HTC Sensation)
I have this issue too. Works fine on my HTC One M7, but when I use the simcard in the verizon G2, no data.
I used LTE Discovery - turns out that when you're connected the LTE and call out, the G2 starts the call on 2G. My M7 starts the call on 3G or H, so I have data and voice on my M7. I am looking for a way to fix this too...

Signal problem theory/research

Hello, i live in a relatively small town where my service provider has very poor 4G signal. but pretty good 3G signal. With the Axon 7 i have a lot of signal problems that i didnt have with any of my previous phones, where outdoor signal is pretty bad and indoor signal is almost unusable. It also connects almost exclusively to 4G, and in contrast all of my previous phones connected almost exclusively to 3G. Over the last weekend i traveled to a major city where my service provider has very strong 4G signal, and the signal problem was almost non existant. I even had signal in places where other people with the same service provider did not. So my theory is the following, assuming that the hardware (antenna) used for 4G and 3G is the same, it may not be a hardware problem, but a problem with the software having a hard time knowing which band/signal it should connect to. It seems that in my case it prioritizes 4G signal and the cost of a VERY unstable cellphone service. This is also assosiated with the fact that when it connects to 3G (incredibly rare), the phone goes inmediately from 1/2 bars to 4/5 bars. I also changed the SIM configuration to leave LTE out, but either for a visual bug or a software bug, it keeps connecting only to 4G. So could this be the problem that me and a lot of people in low 4G signal zones are having? Is there anyway i can force the phone to connect exclusivly to the 3G signal to test if that is indeed the problem?
Regards!

Without knowing which model Axon 7 you are using, where you are using it, and who your provider is, there is little anyone can do to help you. All I can say is that it helped me A LOT to go into settings and turn off
VoLTE.

U model last update, using it from Argentina, and the provider is Claro. I have LTE disabled in SIM confg as i already said and VoLTE turn of as well but the phone keeps connecting to 4G no matter what i do, even if i configure it to only GSM
I don't think its a matter of position or provider (version could be if different software is provided), but a general issue with the phone and band/signal interpretation coupled with the apparent innability to go off 4G
Refards!

ok when it connects to LTE it says "4G LTE". The 4G that you are getting is probably HSPA or something. And we had someone on here a few months back using Claro in Argentina and they had to seek answers from their Claro

If "4G LTE" is 4G and "4G" is HSPA, when only a "G" appears, what band am i connecting too? Its still pretty weird that im having major signal issues in my town, but when i go to a big city my signal is even better than other phones, it seems inconsistent with the whole "bad hardware" theory. I talked to Claro and it seemed like from their end it was a non issue, can you point me to the thread to see if he got it fixed somehow?
Regards!

/Trolling a bit/
I'm always LMAO when I hear US people talking about that 4G scam (which is H+ for real btw)
G is for 2G
E is for 2G+
3G is 3G
H is 3G+
H+ is 3G++ (an intermediary protocol up to 42MBps)
4G is LTE (up to 150Mbps in the EU most of the time)
4G+ is LTE-A (which is available in most of the EU, SK & JP) - up to 600Mbps, 200MBps in most tests
I've not heard of an app that could modify the way the phone "clings" to 4G LTE, since that might likely be the modem firmware doing it on its own.

Then this is even weirder, because is G is not 3G, but 2G it means that the phone NEVER connects to the major band that all of my previous phones and Claro users connect to. Is there anyway to force to only connect to 3G?
Regards!
i have the G european model, in my town i have bad lte signal 1/2bar, when with my previously xiaomi mi4c was got 4/5 bars (maximum). In the big town i have got in the most of cases 4/5 bars. I think the "signal problems" are relatives of a lack of somehow software. i told this because i've read with the china model with the last updates an improvement of the signal reception of the phone.

You can however force a specific protocol indeed, but you will lack the ability to autoswitch networks. Just download 4G LTE Switch (here) which is a glorified secret code dialer. Just click on prefered network and change at your convenience (4G LTE only, WCDMA only - H+ - and so on). Remember that if you force 4G LTE in an area in which you have no coverage, you won't have internet, and no 2G/3G fallback (so no texts, no calls)
I don't know if this is the same problem, but my wife has an iPhone 6+ and I have an A2017U on B29 stock root. We both use the same network (Movistar Mexico) and while her iPhone often registers LTE, my A7 often registers 4G or even E in the same place. The A7 is receiving the same bands but appears to be "choosing" or locking into the slower protocols more often.
EDIT: NEVER MIND… an xposed module was messing with my network settings. Fixed it. Now I get LTE right away.

Lg k8 4g bad network receiving

Hello. I have Lg k8 4g and i found a bug. Bad network receiving. Suddenly i was without network. Switching between lte and 3g is bad. The cell doesnt have network some times. And i switch 2g 3g and is not better. I had only 2g and i had bad network receiving. Suddenly i didnt hear the caller. I was thinking. Or is software issue or it is hardware issue. What do you think???

Try to make a hard reset ( http://www.hardreset.info/devices/lg/lg-k8-4g-k350n/ ) and test your phone (all your data will be lost!!!). If nothing changes then it's most likely hardware issue.
Maybe is up to carrier, what happens on other phones, maybe this phone doesn't support frequency of your carrier?
