Oneplus 8 voice calls break up(?) - OnePlus 8 Questions & Answers

Hi there. I have a Onplus 8 (IN2013) and for some reason when talking on the phone sometimes the incoming conversation breaks up so as to make it unintelligible. I ask the caller to call me back and the same problem happens. When I asked the caller to call on my lady's Oneplus 6 it worked fine.
I use T-Mobile with both VoWiFi and VoLTE enabled. The Oneplus 6 is exactly the same. The problem occurs only on and incoming phone call. It doesn't happen when using Google Duo or similar. The weird part is that only my phone is affected, no others.
Does anyone have an idea of what the problem might be? Is there any way to fully reset the connection(s) to see if that helps?
Thanks,

Can't receive calls on honor 6 x

Hey does anybody else have problems receiving calls from honor 6x? I can call and and text but can't receive calls. The caller hears the phone ring and then go to Voice mail but my phone doesn't even ring.
Are you using Jio, VoLTE or something like that to make calls?

sometimes just restarting the phone fixes these kind of unexpected problems

Yes I already tried restarting as well as blocking all call forwarding and still no luck I'm wondering if it might be a problem with the update I presently have EMUI 5. 0.1

Last; updates went always fine? It's the only one issue that you've encountered?
Anyway, did you ever took in consideration the idea of backup all your important data and factory reset it..?

I'm having the same problem - just this past week. I'm missing very important phone calls as well and I can't figure out why. My setting show that the ringtone volume is all the way up. It's not on silent. Have you gotten yours fixed?
I'm having the exact same problem. It's random so you wouldn't know that you're missing a call until much later when you restart the phone. I just missed an interview call yesterday and had to email the interviewer to try again after restarting my phone ... this is disastrous.
I'm also having the same problem how do I get it fixed
Not sure if I have the same problem. I can't receive calls and text after the phone idle for approx 2hrs. Launching dialer doesn't help. I factory reset it twice and no help. I discover placing a call will make it, or reboot. Still looking into it. Testing my SIM on another phone in the mean time.

I've exactly the same problem that you discribe, but for me it's after 5 minutes idle... I've tested my SIM in another phone (iphone 5c) and the problem persist so it's mayby a problem with the Mobile network operator or the SIM card.
Also experiencing the same issue as well. Thought it was because I was connected to wi-fi at home and calls go straight to voicemail from what callers are telling me.
same here - no incomming calls seemingly at random
Looks like I'm a bit late to the party but I'm still trying to figure this out too. It seems to happen at my house, not sure if it happens other places or not. I also have noticed when i try to make an outgoing call my 4g disappears. Perhaps its not making or receiving calls for whatever reason through the 4g tower / band? I'm just now testing with 4g off but remaining on my home wifi. Annoying for sure. I've been happy with the 6x and hope its not a device specific problem.
I just found this thread after being fed up with this phone. My guess with why this happen is because the phone sleeps. I noticed that whenever Im not using the phone, like when I sleep or when Im working on the computer, it's when I don't receive calls or get delayed messages. It's not just SMS as well, it's other messaging apps too.. My current fix right now, is to send myself a text message, right after I wake up or after I havent touched the phone in a while, and then the messages starts to roll in. If any one of you guys find a better solution, please do let me know, cause this is very frustrating.
I'm having the same problem as so many others with my Honor 6 randomly not ringing. I've tried restarting, testing SIM card, replacing SIM card, "waking it up" periodically. Nothing works. I have both personal and a Google Voice business lines coming through my phone. I'll hear it ring on my computer, but not my phone for about 50% of the incoming business calls. Personal calls I just miss.
Has anyone had any luck with a solution, other than dumping it and buying a new phone? I keep thinking it must be some setting that's set wrong.

Unable to receive calls

Hello,
I bought a mi mix 2s some time ago and it's currently running the china rom because I can't unlock the bootloader the next 10 days.
First of all I can call other people and I can use mobile data. Also I'm able to receive calls if the sim is in my old oneplus one.
Now to my problem:
Today I realized that there must be a problem if someone calls me but I couldn't really figure out under what circumstances the issue appears.
However, I could figure out the following:
If I'm on wifi calls work most of the time
If I'm on 4g I don't receive calls most of the time
If I'm on H+ I receive calls most of the time
If the phone is locked I either get the call or the mailbox answers
If I don't get the call there are two things that happen on the phone that is calling me:
If it's a samsung theres just one loud beep and the call ends
If it's a LG there are fast beeps (similar like if the phone is busy)
Thanks in advance for any help
Flatric
EDIT: Just figured out that the problem is that the phone takes too long to switch from 4g to 3g since VoLTE is not supported by my carrier... Found some guys in a forum who complained about the same problem but with a oneplus phone... I'm still open for any ideas that could fix that Maybe someone from germany here who uses O2/Eplus network and got the same problem?
EDIT2: http://en.miui.com/thread-935378-1-1.html Used this to enable VoLTE but can't test if it's working until tomorrow
Fixed it by the way by enabling VoLTE with the miui dialer code explained here

Verizon incoming call issue. Anybody else?

I am on Verizon and have CDMA-Less profile enabled. However, my incoming calls (and some outbound calls) are often not working. What i mean by this is that I hear the person on the other end of the line as garbled noise, not necessarily static, but more just jumbled electronic noises. The other person says I sound fine. Hanging up and calling back doesn't resolve the issue. If i voice call over Duo it works. Running latest 9.5.11 and the update still didn't solve the issue. This doesn't occur all of the time, but it is more often than not.
I see no one has replied and my reply won't be much help but let you know I've had my OP7 pro since release on Verizon with no issues at all after the CDMA less setting. Possibly toggle on and off the air plane mode after it happens and try the call back. Just a shot maybe.
Try calling Verizon and get them to sync the account. There might be some configuration error on the billing/technical side. I've seen this work for a couple people who described the same issue you are currently having.
Just an update. I went to Verizon and had a new SIM installed. Did a couple test calls using the phones there without issue. Attempted calling my wife and issue sprung up again calling her S10+. Tested calling their S10+ in the store without issue. Tried calling wife again and had the same problem.
Later went to another Verizon store and could not duplicate the problem, but switched her SIM card anyway.
Did a little research on the S10+ and it seems the problem may be related the phone set to Global vs. LTE/CDMA. Changed her setting to LTE/CDMA and haven't had the issue happen. Calls also seem to sound better too when i call her.
Very strange all around.

Question Problem with calls.

Hi guys! Is anyone having problems with calls?
Sometimes when people call me, 3 things happens:
1. I don't receive the incoming call at all;
2. The other person hears nothing (no beep beep sound) and this silence goes on and on forever;
3. The only way to stop the "call" is to turn off my pixel 6a. Then the other person will hear the voice mail saying this number could be non existing or turned off.
If I start a call I have the same situation of point 2: Silence forever.
Usually a reboot solved the problem but does not work anymore since Monday.
Slammed my sim into my old Pixel XL with lineage os 18. Everything works fine.
Pixel 6a Android 13 5 December patch.
Any thoughts? Thanks in advance.

Question OP9+Google Fi+intermittent outgoing call issue

I have an unlocked originally-T-mobile OP9, with Android 11, and I have an issue with Google Fi that I couldn't find online references to.
Every so often, I can't make calls: the dialer starts to dial and then stops within a fraction of a second. A reboot always solves the problem, but then the problem comes back eventually. Data works fine.
Update: I can't receive calls in this state either.
I tried using the beta Google Phone dialer, and maybe even some third-party dialer, and the issue is the same.
killing the com.android.server.telecom:ui task solved the problem without a reboot, and now I have a Tasker shortcut to do that on my home page, but that's not really a viable solution given that incoming calls don't work when the issue happens.
Does someone maybe have a version of Telecom.apk from a different firmware that I could try?
A bit more experimentation: When the phone is in the bad no incoming/outgoing calls state, if I turn off mobile data, or switch it to 2G, everything works again. Then when I switch back to 5G, calls don't work (but data works). Is it a VoLTE issue?
Bump... Am I really the only person on XDA using a TMO OnePlus 9 on Google Fi? Is anybody using an international OnePlus 9 at least? I might want to change to international firmware then.
Well, I think I've solved it by installing international firmware. My guess is that the problem had to do with VoLTE support in the T-Mobile firmware.
