On my OnePlus One, my call quality has been funky. I am on the most up to date CM - Cyanogen12.1.1 build LMY48Y. My signal bar shows high, but the person I'm calling says I keep cutting out and they can't hear what I'm saying. I can always hear the other person. This continues for the duration of the call. If I call back, the connection is then perfect (or not - might take a couple more calls). Once connected, my voice either cuts out the whole call or it doesn't. (This doesn't change during the call). My calls never disconnect.
Is this a potential issue with the radio? Maybe during one of the OTA updates, the radio was changed recently? Where's the best place to start? A factory reset, or flashing a new radio? I have not rooted the phone yet, if that makes a difference.

On my previous Sprint phone, the Hero, I was able to change the slot cycle index through the programming menu, to get rid of ringer lag.
I can't seem to find any threads on doing the same thing for the NS4G. There is one for the Epic 4G, would that maybe work on my phone?
The problem is that some calls coming in don't ring, and I don't see that I had a missed call. I suspect it's because it's ringing the Google Voice server first, but the lag prevents it from ringing my phone in time.

Slot cycle index is only if the call you receive has a delay. The best way to check is to call your cell from a landline and see how many times it rings before your cell rings. If it's 1 or 2 rings, that's not gonna help you at all to change it.
Either way, you need to use QPST to do it, so it's similar to any CDMA phone.
Couldn't find my exact situation. Called ATT and they have never heard of it before.
ATT gs3 running CM10, has happened on nightlies as well as the stable
factory reset, reflash, same issues
1. Have phone charging or leave phone alone for 3-4 hours
2. Will not receive incoming calls. No call screen, not just silent.
3. No missed call notification
4. No voicemail notification if voicemail is left
5. my signal strength shows the radio is on and has high signal strength.
Work-around:
1. I just have to use the phone features (calling out, dialing voicemail), then i can receive calls again.
Because I don't have to reset the phone I feel like whatever service for dialing/phone is shutting off to save battery, but won't "wake" until i make a call. I would like not having to make a call every few hours to receive incoming calls.
Haven't heard of this you may want to ask this in the att forum. This is the Verizon one. It may be something that is an att cm10 problem.
Sent from my SCH-I535
Purchased an S7 AT&T version for my GF. Its running on straight talk and has Android 7.0
Callers (including me) are constantly complaining that they can't hear her. It's like every other word gets lost. She can hear the caller fine.
I turned off the HD voice options - no help.
Looked everywhere for the noise reduction/cancellation settings but can't find it.
The case she has is wide open at the bottom, not just a pin hole for the mic.
Here are my next steps please reply if you have any other thoughts.
- Record and play back audio to make sure the mic is ok.
- Somehow compare cell signal strength to another phone in the same location.
-Call using "hangouts" (think this uses mobile data instead of cell signal for call)
-Use a bluetooth head set for call.
- try a different sim??
- Hate to do it but backup and do Factory reset.
Thanks for any help
Clear the cache and data of the phone/contacts apps
I have a G8142 with the latest security patches/updates on AT&T.
I'm having a strange issue occur on probably one out of every two or three calls. After about 45-60 seconds of conversation, my mic will cut out. I can still hear the other person clearly. I can end the call (this is not instant - it hangs up for 3 to 5 seconds) and then call the person back and resume conversation normally.
A few notes:
It doesn't matter if I place the call or if I am called
The duration from beginning of call to cutting out fluctuates
My microphone diagnostic indicates it is working properly
The call does not seem to actually drop - it will go on for quite some time (with me able to hear the other person) until someone eventually hangs up
Calling the person back/being called back does not fix the issue (it can happen multiple times in a row with the same person/call sequence)
Signal strength is usually -80 or better
The phone functions flawlessly otherwise. There also don't seem to be any issues or drops with respect to the data connection, and SMS/MMS messages seem to get delivered immediately every time. The phone hasn't been dropped or exposed to any liquid. I have disabled some system apps (like Facebook), but none that seemingly have to do with making phone calls.
I have full bars most of the time. I force 3G+ on the phone, as the 4G+ (LTE) signal is weak in many areas. AFAIK that only affects data rates anyway.
It doesn't seem to happen as much if at all if I put the call in speaker mode. I have not used a bluetooth headset for calls to see if that fixes the issue.
Here's some things I've tried:
Rebooted the phone
Updated my IMEI with AT&T. I'm not sure if they actually did it (they stated it was "already changed") or if it makes a difference. My last phone was an unlocked Nexus 6p and did not have this issue. I did not get a new SIM for this phone.
Double-checked and redownloaded the APN settings.
I haven't tried voice calling through a third-party app, like hangouts or whatsapp, but I assume it would work just fine because it's being transmitted over data.
There is either a GSM/setting issue on my end, a settings issue on AT&T's end, or possibly a hardware issue (like a loose SIM, faulty mic, or bad antenna).
For now I'm at a loss, and any ideas would be greatly appreciated.
*** UPDATE ***
I've tried clearing the phone app cache and making sure that battery optimization is turned off for the app. I'll report back if this seems to fix it in case anyone is having a similar problem.
*** UPDATE 2 ***
That didn't work. Calls still drop intermittently. I've pretty much narrowed it down to a problem with the antenna, AT&T towers not particularly caring for the baseband firmware on this phone, or an issue with the dialer app. Performing calls over data (like Whatsapp/Hangouts/Duo) works flawlessly.
We'll see what happens if the phone app gets an update, or maybe after Sony releases the Oreo update.
For those US XZP users on AT&T or those that were considering buying this model, be aware this issue may affect you.
*** UPDATE 3 ***
Changing the mobile radio to 4G (preferred) instead of forcing 3G seems to have solved the problem.
I am on the latest update of OP7 . I have noticed, that often I lose the ability to make or receive calls. If I call any number, it will disconnect with one tone, incoming callers hear my phone is switched off. Although I never notice this as my phone shows full network coverage unless I make a call myself. I have to toggle airplane mode to fix this or clear the phone management system app. I am not the only one who is facing this issue, other users facing the same. I do not think this is a hardware issue, but more like a software issue (I have a feeling it has been deliberately done, to force users to upgrade).
