I recently switched from an iPhone 5 to the One Dev Edition. After having some signal issues, I went to AT&T, got a microSIM, they switched me an Android data plan, etc. But I'm still having an issue where I can't reliably send and receive calls, especially from my desk at work. I can dial the number and hit Call but that's it. No ringing, nothing. Just dead air, then the "call" ends. If the call does go through, I can hear the other person but they can't hear me. Same thing when receiving a call. I'll hear them but they can't hear me. Sometimes my phone won't ring and it just rolls to voice mail. I can see the signal switching from LTE to H, etc, and I have practically full bar strength. I just don't understand why the calls aren't going through.
Is this an issue with the phone itself? Something with AT&T? Is there a newer radio firmware I can try flashing? I didn't have any issues with the iPhone 5, and I even had my coworker put his iPhone into field test mode so we could compare the numeric signal and they're about even, though the iPhone usually does have a slightly better db signal. I really like the One but not being able to send or receive calls while at my desk is a deal breaker.
Thanks!
From the sounds of it, you are running the stock firmware still? Any root or other possible modifications? If you answered Yes then no to those questions, I would head back to the AT&T store and have them try it out, if anything they should be able to take your SIM card and put it into another Android device and see what happens.
What about text/data, do those work?
You said mainly at your desk you notice this issue, so does that mean it happens at other places as well, same symptoms (full bars, allows to send call then nothing?) You may just be the lucky contestant with a defunct unit, HTC should be able to help you out.
I would suggest first going to AT&T store, try out their suggestions, then if anything give HTC a call/email to see if they can be of any help. At this point I would stay away from flashing custom radios as they may void your warranty then you will really be up $hit creek.
Sounds like att.
I had this problem with tmobile once. The signal wasn't strong enough and it wouldn't call.
Some please are spotty.
Something is wrong with your phone. That should be obvious. Of course the vast majority of people who got this phone can reliably make and receive calls or it would be the biggest mobile phone bust in history.
Sorry to be blunt but you already know it's not the signal so it has to be a defect in the phone.
Thanks for the suggestions. This is the stock Dev Edition ROM. I haven't made any changes other other than just installing apps.
I haven't made a lot of calls but I don't seem to have an issue any where else.
No issues with LTE. Data has been fine.
I wasn't sure if AT&T would assist since this is the Dev Edition but that's worth a shot to have them run some tests on it. Otherwise I'll try to get a replacement (or refund) from HTC.
Thanks!

I have VoLTE and Wi-Fi Calling turned off. Sometimes when I answer an incoming call quickly (actually that doesn't matter), I just get silence and I can't hear the caller and they can't hear me. I have to hang up and try again; Anyone else encounter this?
Update: I think I narrowed it down. Apparently the first call I receive after rebooting my phone always fails (unless I've made an outgoing call first). Subsequent calls work fine until my phone is powered down or rebooted, then the 1st incoming call fails again. I can reproduce this 100% of the time.
I've had this happen a couple times, funny thing is I've had it happen on my S4 and S5 as well.. Im starting to think its Tmo's network.
It might be a glitch with T-Mobile's network, but I haven't encountered it on previous devices. For example, I just switched from the Nexus 5 and never had a problem with voice calls.
I've had this happen a few times also with my S6. Never happened before, and I've been with T-Mobile for over 2 years.
This only happens for me occasionally if one of the callers is on Wifi calling, but it's happened with every phone (not just the S6) so it's definitely a network issue
I found this related to the S4, http://thedroidguy.com/2013/06/gala...ting-incoming-calls-66029#jMqaFVvIYCDRQHse.97. I've disabled the mute function in motions and gestures. We'll see if that works.

Been with Tmo for 5 years now and I have had this happen on previous devices.. could be the area I am... lol, I also notice a delay when making a call out which I believe is the network
Never had this problem on S4, but since getting the S6 this problem has been bugging me. Very frustrating.
Ok, I've got a problem that just started happening the last week or two. When certain people call me, I can answer. However my phone always hangs up on them 1 second after the call. The behavior is the same, based on the number calling me.
For instance, if my wife calls me from her cell phone (Sprint iPhone 5S), it will always hang up immediately after answering.
If my wife calls me from our house phone, it always works like normal.
This so far as I can tell, only affects inbound calls. I have no issues calling out.
Running latest OTA. I've updated PRL and profile, and it made no difference. I've never rooted the phone or messed with S-on/off. Pure stock. I have rebooted the phone into safe mode, and the same behavior is present.
Interestingly enough, I'm also on Sprint, I have a Nexus 6 and my wife a Note 4, and we've had the same issue over the past week or two. She can call me and immediately after answering the call will end. This has happened with her calling from her cell phone and her office phone, both of which are attached to her contact. I can call out with no problem, and I've tested calling my phone from different numbers and had no problem. No clue whats going on.
Are one (or both) of you using Sprint's Google Voice integration?

I am having the same issues when my mom (S4) whose on the same contract as me, calls me (S6 edge) it always hang up immediately after I pick it up. I have no issues calling her though. I am using Sprint's Google voice integration but I do not believe my mom is.
It is the Google Voice integration that is causing the disconnects.

I'm having the same problem with a Metro PCS phone. I've seen it elsewhere on line - it's some Android issue.
In the last few days I've had at least one dropped call per day on my S6. It doesn't make any difference if my recipient is on a cellphone or landline nor does it matter if I'm in the car on bluetooth or using the handset elsewhere. I did some searches and found others having the same problem, not so much with AT&T (mine) as opposed to Verizon and T-Mobile. Some say a factory reset cured the problem, but I hate to do it unless I have to. Just curious how others on AT&T are faring. My previous S4 never dropped any calls nor did my HTC M7 so I'm thinking it's not a network issue, but something in the phone itself.
I've never had a dropped call in the month I've had the device. I had my chubby cheek hang up on my mom once last week, but that's as close as it gets. My area gets pretty good coverage for att and tmobile though. I've yet to drop a call since joining at&t
My Black Galaxy S6 Edge 64gb module was dropping calls like crazy, and was still within my exchange period so I switched it out. Haven't had any dropped calls since.
Call and connection quality have been stellar for me. Only dropped calls I've had are when going through known dead spots.
Looks like the factory reset fixed it for me so all is good now.

Have you had any dropped calls since your last post here? I'm having dropped calls often. I don't think a factory reset will help me because I wiped all data before flashing the rom I'm running. I may try a factory reset from within the settings menu if you haven't had any dropped calls since the 15th.
I've only had a couple dropped calls since then, but my problem now is that sometimes the other caller can't hear me, specially when I'm driving and on bluetooth through the car audio. It can't be the other caller because they were on a stationary, land-line phone. I checked out my mic by making a voice recording so the mic is fine. I just tried unchecking "Enable HD LTE Services" and I'll see what that does and report back. If it were not for the very nice camera, the annoyance of the dropped and muted calls plus the bad battery life would be enough to make me switch this phone. It's got to be a device-specific bug. My HTC M9 is running Android 5.0.2 and is rock solid and never dropped a call. Same with my LG G3. I would send in my S6 for repair, but I'm not sure what they would do. Not only would I get a refurb back, but it might do the same thing. If you've been following the threads, you might have seen that Sprint had to push a special update for it's S6 customers to fix dropped calls. Verizon customers are also having it bad (I'm on AT&T). It can't be all network issues though as like I said, my other devices including an LG G3 have never dropped a call.
Thanks for the response rmc69. I did uncheck the HD lte and it did not help me at all. Let me know if you have a different result. Thank you
The Sprint S6 and S6 Edge have the same problem. I have to turn off the LTE radio all together to have a usable phone. I couldn't send/receive text, I had dropped calls and a very poor signal. Once I turned the LTE radio off, all those problems went away. I realize this is not a fix but it's a workable bandaid for those that are having problems. Good luck to you guys.
Turning off lte did not work for me.
Robert, how did you turn off LTE? By going into the testing mode and changing it from there? Or were you simply referring to unchecking Enhanced LTE Services?
I think I figured it out from this thread, at least for AT&T

I tried that, it did not work for me.
Sorry turning off LTE still didn't help. I guess the only alternatives now would be to wait for 5.1.1 and see what it fixes, or you may just consider asking for a replacement.

Yeah that is what I'm afraid of. Every time I go to the at&t store it's a big hassle. Hopefully an update will fix our problems.
@rmc69, is your phone rooted and running a custom rom?
No; pure stock. It's also a 64 GB model. I'm wondering if there is a difference that could affect reception, i.e., is the antenna placement exactly the same. I changed my band to GSM Auto last night removing LTE and so far, I haven't had any dropped calls, but it's too early to tell. The biggest problem I'm having is that sometimes callers cannot hear me, especially in the car using bluetooth.
I am rooted running DennisRom. Yesterday I did a factory reset via the stock recovery and made 4 calls and did not have 1 drop. I'll see how it goes for a few days and report back.
Great! That's encouraging.
Bad news, I just called my wife and the call dropped before she could answer her phone. I think I may give up and get a different phone. I'm loosing hope.
My fiance and I are both having problems with our text messages sending twice, terrible call quality, and a delay when receiving a text message.
We have tested this in the same room, and sometimes it can take 5 minutes to receive a text message. (I know it doesn't literally travel across the room).
Everyone I talk to on the phone complains about call quality and that they can never hear me. My microphone is clean and I don't have anything obstructing me otherwise.
Just looking for simaler experiences. And if anyone has done anything to fix this. Thanks!
do you have a AIR-RAVE at home?
I found that wifi-calling is crystal clear and text are much faster with it on. I have very poor coverage. I have the sprint magic box but it doesn't get enough signal to work.
my wife has been having issues with her S8 and i sometimes get dup texts or even missed texts. I have had sprint for over a decade but both got new phones last month and the quality hasnt been that great, i have a unlocked Note 8 and have activated the HD voice via shortcut master but the calls even to my wife def arent the best quality. not very happy
