No voice after make or receive a call, after restart phone, everything is ok - Xiaomi Poco X3 NFC Questions & Answers

Hey Guy's
I have POCO X3 NFC with MIUI 12.0.4, TWRP, Magisk and Call Recorder SKVALEX.
From couple days I have problem with receiving or making a call's. When I call someone, the person cannot hear me and I cannot hear that person. Only after restarting the phone, the situation returns to normal for a longer time, e.g. an hour or two.
The same problem occurs when I receive a call from someone.

Same

I am using Poco X3 NFC and facing the same issue. I haven't installed any custom rom. Its on the stock rom.
I have watched a lot of videos to fix the issue which suggest to restart the phone. Although restarting the phone addresses the issue temporarily which is quite awkward.

[Q] There is no sound when making calls?

I recently noticed this problem, about a week ago. Whenever I make a phone call, I can not hear the person on the other end, but they can hear me.
I just installed a new rom (Clean Rom 5) and I still have this problem. The speakerphone works fine...
Any ideas?
Thanks

Help - No audio/mic in cell call, but voip works fine

I have an HTC Droid DNA with Verizon. It's almost 2 years old. I set s-off about a year ago, and have root access, but I didn't flash anything. It's worked fine this whole time. Yesterday morning i made a call without issue. Then, in the afternoon, when I tried to make a call, there was no sound during the call. I made no changes and it suffered no damage in between. If I try to make a call. the call connects, the other person gets the call and answers it, but I can't hear them and they can't hear me. Same with incoming calls. My phone rings, I answer, but neither of us can hear the other one. I've tried the speaker phone, headset, and bluetooth with the same results. I've also tried making a call through google hangouts, and the sound works just fine.
Checked mute/volume settings. Restarting multiple times didn't fix it. I finally decided the only solution was to wipe everything and reflash a stock rom. I flashed hboot, radio, and then the ROM. Still no audio in cell calls. I'm at a complete loss. Is it possible this is a hardware problem? A problem with some account setting on Verizon's end? Any thoughts our suggestions would be appreciated.

Other side in calls can barely hear me in most calls

Hey guys,
since amazon is out of stock - and therefore, getting a replacement device is kind of difficult - and I'm still waiting for oneplus to respond, I'd like to hear from you if you encountered similar issues with your OP6:
During calls, I can hear the other side just fine, but the person on the other side can not hear me most of the time. Sometimes, it seems some shreds of voice are being transmitted. It happened on about 90% of calls. There are calls that are perfectly fine, but most of the time, the phone is unusable.
What I could test so far:
- it happens in handset mode, speakerphone and with a bluetooth headset
- it happens on both SIMs, swapping them does not change anything
- it happens on 2G as well as 3G (no VoLTE available yet)
- the microphone works fine if I use the audio recorder (outside of calls)
- calls made via VoIP-software seem not to be affected, though audio quality on the other side isn't that great either (but that might be unrelated)
- sometimes, it seems to happen mid-call
Both SIMs did obviously work fine in my previous device (OP3), signal strength in calls is about -70dBm, both SIMs are on T-Mobile (Germany).
I'm on an A6003 with OOS 5.1.5, Baseband is MPSS.AT.4.0.c2.10-00012-SDM845_GEN_PACK-1.147963.5, bootloader is unlocked and rooted with Magisk.
I did find a thread describing similiar issues on the oneplus-forums (https://forums.oneplus.com/threads/dual-sim-issues.838595/#post-18474985), but I'm currently unable to login to their forums, for whatever reason.
Can any of you guys give me a hint on what to test to narrow down if it's a hardware or a software issue or maybe even suggest a workaround?
I'm happy to provide more details where necessary.
I'll probably have to switch back to my OP3 anyway, so I could give the Android P beta a shot and see if it happens there as well.
Best Regards.
So, it turns out (*after* factory resetting and flashing Android P of course ><) that the echo test number I've been using is equally broken on otherwise working phones, so most of my test results are null and void. I'll give it some more testing...
Just a heads-up for users who may stumble upon this thread in the future: call quality problems are mostly gone after updating to 5.1.6 (and replacing SIM-cards).
I've bought a OP6 just three days ago and I've updated it immediately to OS 5.1.8 (I've also rooted it) and the phone calls problems (call drops and other person can't hear my voice sometimes) are present.
I hope OnePlus will fix the issues not so later...
Unfortunately, I can't rule out that replacing the SIM-cards actually fixed the issue - it might be worth a shot. I haven't had any issues since my last post.

Incoming calls problem

Hey guys!
I'm having troubles with not receiving incoming calls from certain people. No ringing, no notification, nothing in call history on my side. The other side can initiate the call, and it rings too, but nothing on my side. I can still call them and receive sms from them. I have no idea why or what causes the problem, nor if this phone/software or service provider issue. I tried the obvious reboot several times and switching the sim to the other slot, didn't work. Remaining options are wiping everything and do a full software update from scratch and talk to the service provider if the previous won't work.
I was wondering if anyone ever had an issue like this? Maybe on another phone? All people who can't call me now, could reach me before this started.
I have 64 GB op6 with Android 10 stock.
Same problem here
There are no signs of a call from certain numbers, even though the other side gets a ringing tone.
I am on OP6 latest stable oxygen os 10.3.2
Did you fix it? Anyone else having this issue?
I have the exact same problem on my OnePlus 6T on Oxygen OS 10.3.2 ? Please help
hey, did you guys manage to solve this issue? i have tried my sim in another phone and it works flawlessly, perform a full wipe (clean flash from RR Android 10 to EvoX Android 11), so wiping data does not help, neither wiping all the phone cache... please help!!

Poco X3 NFC Incoming Calls Must Be Speaker First

Hey guys,
I currently have a problem with my poco x3 nfc, where when I receive an incoming call it is completely quiet for both ends. My caller and I don't hear each other. However, when I switch to speaker mode and then back to normal earpiece, it then works suddenly (and speaker phone also always works currently). I'm not the most technical user right now and did the basics of factory reset and all the updates, but I think it's time to go extreme and talk to the elite community if they have a hardball fix with flashing and unrooting magic. Don't know if anyone else experienced this before (maybe on another device?), but it's a major inconvenience more than a life ending problem. Let me know if there's any suggestions
Thanks a ton!
