Hello everyone.
I had this phone for a month now, and I kept having this problem...
I don't know if you all have same issue, but I couldn't figure out how I should do to fix it.
Here's the scenario.
1. Talking on the phone.
2. Try to turn on google navigation / map / market or any other apps using data transactions.
3. Any of data related services don't work at all.
I had this problem from the beginning(stock rom, unrooted). I don't remember which rom was it, but I once didn't have this problem but I didn't like that rom and I flashed new other one.
Now, I am using "Cyanogenmod Nightly Build", and still have same problem.
Is it evo's common problem or is it mine?
no problem at all it is the signal sprint uses. It can only either send you phone or data at one time. if you use wifi or 4g you can access data and phone at the same time =]
No CDMA network allows for simultaneous voice/data
Makes cdma feel sorta outdated huh?
Sent from my EVO from the Apple Store.
It is capable of simultaneous voice/data but carriers haven't updated their CDMA revisions in a long time and there's no point now since the only 2 carriers with CDMA have new data systems coming in (Wimax with Sprint and LTE with Verizon) that support it
Yeah, this is a pretty well-known limitation of CDMA currently. 3G data and voice data can't transmit simultaneously. If you have 4G or WiFi you can do simultaneous voice/data.
Thank you all, hope I could get 4g network in LA area asap....

Has anyone been looking into running the 3G and 4G radios simultaneously?
Aside from the benefit of having an additional 1-2MB/s, I get very frustrated when I am in the middle of downloading something and I come into a 4G area. Since the phone will always choose 4G over 3G, the connection resets. I would love to have a way to keep the path available to the app using it.
I guess the same problem exists when Wifi is on and the phone connects to wifi while downloading over 3g or 4g.
Can this be done?
I also would love to see a dev pick this up. It could save my marriage...
great idea. Being able to simultaneously use them and multithread downloads would be awesome.
I'd be happy if someone could fix the transition from 3g to 4g and vice versa. Nothing like downloading a file from your phone and then you lose 4g and it loses the entire session and has to be redownloaded.
Thread moved to Q&A.

That's going to be unlikely, as 3G and 4G are separate networks operated by separate providers (Clear vs Sprint). That's why I want to keep the 3G connection alive.

I don't think clear wire is responsible for everyones 4g, just a select group

I could be wrong but I think sprint just resells clear wimax and calls it america's first 4g network.

When connecting to 4g or Wifi the 3g radio never really shuts off. The data part of the radio goes to sleep while the voice part remains active to send or receive calls or txts.
The 3g data service going to sleep when connected to the others is by design because it is slower than the other two services.
If you don't want the connection to reset turn 4g and wifi off, and only turn them on when you need the greater data speed. (this will also save your battery)
Also another solution is using one of the location based apps that will turn those on and off based off gps location.
Its not that i don't want to use 4g, i wish i could but its not reliable enough. If i have a large download, I'd like it to stay on the reliable network, but i still want to use the fast network.
I agree that the 3g network is still available, I'm hoping there is a way to force a static route over the 3g when needed.

Sounds like a silly request... but see if my train of thought makes any sense.
Background: I have an evo running on pageplus. I've followed the tut's, and had sporadic 1xRTT data working. I also tested running the phone using the verizon (pp) setup for mobile profiles, being simply one profile rather than the three required for it to connect to data.
What I've discovered (using the debug tool ##DEBUG#) is that using the three data profiles, the phone never authenticates for EVDO, and thus, stays at 1X, but the data does work. Using one profile, the phone does authenticate, but the connection never actually starts. I've read that it is because of the way the sprint provisioning works. Needless to say, at 1X battery life is horrendous.. as the phone is constantly trying to authenticate with EVDO cell bands. With EVDO and 1 profile, battery life is fantastic, but there's no data stream.
SO... I'm not sure if the final step of data startup (where the phone checks to see if it is using a sprint mobile data or verizon mobile data) is part of the ROM, or coded somehow into the radio firmware (or both).
I was thinking of trying to port a rom from, say, an incredible or Eris (any VZW phone).. to see if it'll actually start data with true 3G.
I figure XDA is the best place to ask.. these forums have been indispensable to me for all my phone nerding needs. =-)
Anyone have any thoughts on this?
Bueller.. anyone? anyone? Frye?
I'd really love to flash CM9 or an ICS ROM on my Page Plus carried Evo4G, I had it flashed on when I went through Sprint but, what precautions should Itake and is it even possible? Sorry for the bump, I searched and searched and couldn't find info about this since Feb so I'm finally asking
So everytime I call someone or receive a call,
the 3g on the status bar disappears instantly.
right after I end the call,
I have signal again immediately.
is this suppose to happen to Verizon phones?
I'm confused because I came from at&t. never had such thing on it.
So is Verizon suppose to be like this?
if so is there any mod/tweak that enables me to use data while calling?

Yes, this is supposed to happen. You can't do voice + data over 3g, but you can do voice + data over 4g. There is no "mod" available for that will enable the use of data while in a call on 3g.
Verizon is CDMA, which doesn't offer simultaneous voice/data like GSM does. Unless your phone has SVDO (like the Thunderbolt) it won't do data and talk at the same time over 3G... The VZW GNex doesn't have SVDO.
For the longest time this has been a pain for CDMA carriers (the few that are left) and they're gonna get past it with VoLTE eventually. You'll still see AT&T run ads comparing their iPhone to the VZW iPhone because it can do voice+data at the same time.
If you're on LTE, you can browse LTE data and talk on 3G at the same time, however.
maguro user here. i was talking about this with a work colleague yesterday, and i said data didn't work at the same time as voice, only with gprs/edge. he had me call his cellphone, while on UMTS/3g/H, and data call was still on as i made the call, and let the phone ring a few times.
Way too often do I see the phone using CDMA/1X instead 3G, is it possible to force the phone to only use 3G? Seems kind of silly when Verizon offers also 4G phones that they would even bother with anything less than 3G nowadays.
Yeah boss its under settings > mobile networks. I don't see it on Paranoid Android but cm7 and I think cm9 has cdma only options
If you force 3g evdo only then you lose voice.

SMS too if I'm not mistaken

Yulp, one would lose voice & SMS functionality - and/or be dealing with lots of missing calls, voice mails & unhappy folks trying to reach you ...
LOL, I would LOVE to have 3G signal - despite all the commercials about 4G/LTE on our Fios TV everyday - at home, it still meant taking our phones 5 blocks over to pickup 3G CDMA. With backup device roaming on AT&T, no problems whatsoever on GSM/3G and 4G's - if calls aren't dropped inside the house, LOL.
With all the tweaking, kernels & various Roms floating out there, the best we can manage is -85 dBm signal but mostly bouncing around, so 2G is all we get on my grandfathered UNL 3G data plan - running WiFi almost exclusively on a 30/25 fiber line.
It obviously depends on what ROM you are running, but in my CM9 by aeroevan I go to mobile networks and pick LTE/CDMA and that works usually.
Hello,
I just got this phone yesterday. Upgrading from HTC Evo 4g LTE.
Today I was on a conference call and tried to access the web and could not. I noticed I did not have the LTE or any indication of mobile data networking ( associated icons). Does this phone handle voice and data at the same time ( not on wifi ).
If not I will have to return this in disbelief.
Thanks
Mike
Please close this thread. After searching i found this thread:
http://forum.xda-developers.com/note-4-sprint/help/simultaneous-voice-data-t2893885
Doesn't seem like you can use data and voice together. A work around looks like hangouts dialer. I just downloaded it. Error " phone calling is not supported for this account with this version of hangouts ". Guess i'll have to use the search field to see what/if anything can be done.
Even though I got that error message I was able to make a call. Worked on Wifi and LTE network....this might work out.....

This is a Sprint Spark limitation. All Sprint Spark phones are limited to 1 radio at a time, so you can't have 1 channel running voice and another running data. When you are making a voice call your phone drops down to 1xRTT. The up side is better battery life and the ability to use 800mhz, 1900mhz and 2500mhz LTE (one at a time), the down side is no Simultaneous Voice and Data (unless you are on WiFi).
In the long term everyone will move to Voice over LTE, which will allow data and voice simultaneously again. There is no time frame for this yet with Sprint and the Note4 was listed in the FCC specs as not supporting VOLTE.
Do all new sprint phones have spark? Any time frame for volte?
I had heard whether it's true or not Intel late 15 early 16 for the start of roll out of volte.

Thanks everyone. Guess i will have to see if i can do without data while using voice.
Get a note3 pretty close to the same phone ya I know there are some major difference but if u really need date and voice that will be way more important than any lil difference between phones

Thanks @sliverr7x, I would do that, but i want the newest available phones.
