I recently got a ZTE 919D having Android v4.1 Jelly Bean, from eBay.in - /itm/ZTE-N919D-P865G04-CDMA-GSM-Dual-SIM-5-Inch-Quad-Core-Smartphone-8MP-Camera-/271766961121
I am on Relaince's CDMA network and I have been trying to make conference calls with it but it doesn't work. I make the first call and then Add the 2nd participant. When I Add, the first one goes on hold, which is a usual thing. When the 2nd one has joined, I Merge calls and then both should be online. But the first one still stays on hold.
My network provider has enabled conference calling on it and I am able to make conference calls with my Samsung Ace Duos CDMA phone.
So I wanted to know how would I be able to enable conference calling. I've heard I can change binaries of the OS and fix whatever's stopping this. Or could there be any app which would enable the conferencing?
PS: The phone isn't rooted yet and I want to avoid rooting if I can.

Hello I'm quite a novice at cell phone stuff to please forgive me if I'm asking in the wrong place or wrong question.
I bought a Samsung Admire R720 about 6 months ago. It's umm locked for the carrier MetroPCS. I never activated the phone with them because I didn't have the money yet. I just always used the wifi wherever there was a hotspot. I also rooted it because I wanted to use more advanced tools like the wifi analysis and Titanium backup etc. I also used Groove IP on the phone to use my google voice while I was on wifi. Now the fun begins.
I activated the device with Metro online and did all the MEID stuff and the phone seems happy but I cannot dial a call to anyone (unless I use groove ip). When a number is dialed, it rings once and a recording pops up saying:
PS01 Your call cannot be completed. Bye. *click*
Everything else works on the phone though. I can accept incoming calls to the cell phones number. I can text and I can surf the web. All with the wifi radio turned off so I know its going through the carrier.
I'm lost as to why it wont simply make a call out. I have the android toolkit here and can use adb to do anything you ask of me, dumplog push pull... whatever. I've seen the dumplog while trying to make a call and I have a copy of it but I would rather one of you more experienced folks tell me what to search for then post it here. Otherwise the dump is huge and messy because its raw with no modifiers.
Any help would be much appreciated. I do have a ticket in with MetroPCS but I think the real techs there aren't very available or none exist.
Thanks in advance!

The Samsung Galaxy III with Verizon (same with any Samsung on Verizon) won't allow you to release the second party once you merged 2 calls. It also won't allow you to initiate another 3-way call, even if one of the people in your conference hung up and you're only connected to one person.
Once you merged 2 calls, your only option is to end the call which will end both calls.
Samsung on AT&T and TMobile do have the option very easily on-screen.
Though in many forums people suggest its a CDMA versus GSM issue, its not, as all Verizon 4G phones are on the CDMA network and it can be done on other brands like Motorola,
(Tho it's not an on-screen quick option on the Motorola, do the following after you merged the 2 calls: click home, people/contacts, tiny phone icon at the bottom, and then the green phone icon, which disconnects second party without ending the entire call and you can then even initiate another 3-way call). On any Samsung with Verizon, this option wont work. The combination of Samsung and Verizon have eliminated the good old "send" feature that lets you hang up the third party plus have your phone free to continue making another conference call.
I've read somewhere it can be done by doing the following:
"Root your phone and flash cm9 or 10, The dialer on this rom will allow it" (from reading many many posts, i don't feel too happy with trying cm10). (I'm not even sure if he meant i would stil need a special dialer or once its rooted the phones dialer will let me hang up the second party and/or make another conference call)
Has anyone tried solving this problem with rooting successfully? (or any other method), if so please specify what ROM etc, I'm a newbie but relying a lot on 3-way calling. maybe I'm too naive and rooting alone even without flashing would solve this?

I'd love to know as well, I'm having the same issue on my Verizon Galaxy S3. Like you said, the Razr HD can do this with no problem, and every other s3 and note 2. Whats the deal? Can the dialer be added from anther carrier phone? Will the AOSP dialer do the job?

Hi all,
First let me say that you're making awesome things possible with such an old device (bit weird to say that about a 3 yrs old tablet ) Many thanks for all your efforts!
Either with current Omnirom and CM11 my Xoom is receiving voice calls. Regrettably the provider is not able to route calls just to one specific device (got three SIM in total as part of my contract). I can set mute for incoming calls, but the device is for my parents in law. So I'm not that interested in showing them all phone numbers that try to reach me...I could pay some money to get a data-only SIM, but then I could also use the money to buy a new device^^
I have already tried the following to solve it
- removing the Dialer apk -> no voice call button anymore, but it is still ringing
- added lines to build.prop ("ro.telephony.disable-call=true" & hw.nophone=true) -> without any effect, had expected to have WiFi only
So far I understood that EOS 4.2.2 had a USSD mod to activate the telephony function. That means to me the device did not receive calls without this mod. Did something fundamentally change to the telephony implementation in Android versions >4.2.2 or is there a similiar way to deactivate it in CM/OMNIROM? I think they made changes to the framework-res.
Please do not understand this question as a request to the community to program something, but I would like to know if there is a chance to get it fixed (even with some or much learning effort )

Hi,
I am currently in Mumbai, India.
I have sprint Galaxy S5.
I am on Reliance CDMA network.
But i cannot do a conference call {multi-party call}
There is an option of Merge, but when i click merge, the calls merge, but there is no conference call.
I still am on the first call & second call is still on hold.
Moreover, i cannot swap calls also.
I have tried using GSM, conference & call swap works perfectly on GSM.
Can anyone please help in resolving this issue ?
Problems Handling Phone Calls (Call Waiting, 3 way, etc.) Verizon S5 on AT&T Network
recently bought a used Verizon Galaxy S5 (SM-G900V). It came with the lollipop OS. My service provider is H2O wireless (on the AT&T Network. From the outset, I had problems with phone calls, text messaging.
1. When I'm in a call, I'm not able to dial (Like to enter numbers for automated systems).
*I solved this one by going to:
settings>applications>call>
Scroll down to DTMF tones and change setting to long.
2. When I'm in a call, I'm not able to click over to calls on call waiting. When I do try to click over, I still hear the original call for a few seconds and then both calls drop and I get an error message that says "no sim or invalid sim". If I don't answer the call, both calls drop and I get the same message. The same thing happens if a try to make a 3 way call.
3. If someone calls me and I try to call them back, the call redirects to turn it into an international call and the call doesn't go through.
*I solved this using an app called prefixer
4. If I try to text message someone who called me, I get an error message back saying the phone number is invalid.
I figured I would have to root my phone to be able to make some custom changes. I first had to downgrade to kitkat (android 4.4.2) and root it and then upgrade with root using some very helpful posts and resources found on this site (thanks). When I downgraded, problems 1 and 2 went away (for number 1, I had to change my network mode, but that solution didn't work when I went back to lollipop). After upgrading beack to lollipop, all of these problems were there, though I was able to resolve 2 of them, the other 2 are problematic.
I think theres a problem with the way the phone is handling the AT&T network signal since they have a different type of network from verizon but i don't know.
I'm will in try to install a custom ROM, change settings in service mode, etc. I just haven't come accross any info to point me towards the right instructions. Alternatively, I may trade or sell this phone ant get an AT&T based phone. What do you suggest?
