Phone goes into mute - Lenovo ZUK Z2 (Plus) Questions & Answers

I use viper os and for the last few days when i receive a call the phone goes into the mute mode and both
the caller and called are not able to hear a word. If i cut the call and dial back then the call goes thru perfectly.
This happens to all the incoming calls. I tried clearing cache & Dalvik cache but still, the problem persists.
Then i reinstalled the rom again then also the problem persists. Even tried a different rom (AICP) but the problem persists.
The sim works perfectly on a different phone and hence this is no sim problem.
I guess it is not a hardware issue since the call goes thru when i dial a number.
The problem is only in incoming calls. The phone is z2 plus.
Has anyone faced a similar issue and have been able to resolve it?
Thanks in advance.

I suffered a similar problem couple of months ago, clean flash without using the google backup to restore the apps & settings should solve it

Call History Log - not updating on made/received calls

I recently observed that my call log does not show all the calls that I've done or received.
Since then i tried to restart the phone (HTC 10), clear Phone app cache, clear data for it and nothing seems to solve the problem.
Who else had that issue please let me know how to fix it!
Nothing was installed recently on the phone.
I've noticed something similar on all my devices over the past few years, and in my case, it's definitely related to the Extreme Call Blocker app. If you don't have any call blocker apps installed, I don't know what else to suggest other than a factory reset. You haven't mentioned, but others who would potentially help might need to know if you're on stock unrooted, and what build of the stock ROM are you on, and if rooted and flashed a custom ROM, which one and which version.
Make sure it says 'all calls' under phone book at top of screen

Phone Call Sound Problems

Hello. Does anybody have an idea why there is no sound whenever I send/receive calls? Also, the UI/related app crashes whenever I do the same.
No problems when I uses SMS though, so I don't think it's a signal problem.

Maybe a theme issue?
Nope. Just reformatted the phone and did not install any theme/launcher apps
Same issue
I've been having the same issue and I have no idea why. Performed a factory reset. Tried running the phone in safe mode. It seems like it works briefly after a restart but then cuts out after a few minutes. I never had any issues like this before the update.
Problem for me goes as follows.
Receive phone call
Try to answer
Either the phone answers the call and there is no sound (mic or speaker) but otherwise acts normal or the phone refuses to answer the call and the "swipe up to answer" UI keeps reappearing. When the later happens the phone crashes and goes through a restart that takes longer than a normal one.
Make a phone call
No sound (mic or speaker)
The issues with the microphone seems to affect other parts of the system as well, such as ok Google and voice typing.
Speaker seems to work fine other wise
Putting the phone in safe mode seems to delay the problem sometimes.

Me too. Bumping in hopes of a fix.
Same. I'm running a custom ROM and haven't upgraded to 8.0 yet. Does the issue persist with 8.0? Google told me today to revert to stock and upgrade to see if that fixes it.

Same thing started happening for me yesterday!
I was sending a voice message on Whatsapp.
The msg was sent but no audio was recorder.
I received a call but there was no audio (both in & out)
I tried making a call and the same happened.
The "Phone" app would even hang after hangup and would crash. I get a white screen with the G logo and a loading bar beneath it, then it would start.
Starting the phone app is also sluggish.
If I make a call (and get no audio) I try to switch to loudspeaker and I could hear the other party but for a couple seconds then it's muted, then comes back for a couple seconds, and keeps doing it intermittently.
Sound from music app and videos works fine.
SOMETIMES after a reboot phone audio&mic would return but temporarely.
SOMETIMES when I try rebooting and it doesn't work, I try safe mode and it work (not all the time though)
SOMETIMES switching from LTE to WCDMA only fixes it temporarly.
This is really unpredictable.
I reverted back to a 7.1.2 stock. At first the issue persisted then it was fixed for a couple hours.
I updated back to O and audio worked for some time but after a few minutes, the issue returned.
Now I am on a clean stock install of O. without any apps installed. The audio comes back for a few minutes, then it's gone for hours.
Hopefully this thread will grab the attention of someone who might be able to help
Having the same issue on a regular Google Pixel. Also Google Assistant is not working using the "Ok Google" voice command and the phone app - answering and ending calls lag - same issue mic and speaker do not work. In Safe work, they work but on rebooting same issue persists.

bump - hoping someone has heard something somewhere.
Same here for my regular pixel, this is really annoyed. It just starts happening after almost 12 months since I got it.

I have been having these same issues with my phone. I noticed it happened after I downloaded the what's call app to make a WiFi call. I noticed another user had the problem after installing what's app to her phone. Could this somehow be the problem? I am not super tech savvy but I am convinced it is related to my downloading the what's call app. I have uninstalled the app. Still the problem remains. Any ideas? Thanks.
Has anyone that posted in this thread was able to resolve this issue? I also have this problem, I'm currently waiting for it to happen again so I can pull logcat but no idea what I should be looking for since I have no idea what can cause not being able to hear the caller so randomly.
I was originally suspecting V4A, but last night I flashed stock system img, did not install V4A and same issue occurred.

Difficulty answering calls

Is anyone else having a problem answering calls? On an incoming call, I can hit the green button over and over, yet it won't answer. Sometimes, I can get to the full dialer screen where I can swipe down to answer, but in my panic to answer, can't seem to get to it every time.
I've also noticed that oftentimes, pressing a contact to dial them will take up to 30 seconds or so. Just as with an incoming call, I can press it over and over, to no effect... then all of the sudden, it will start dialing.
My first sim is TMO, and the second is AT&T. I am still on 5.0.3 and have been ignoring the 5.0.4 update, since I'm worried about losing TWRP and magisk and don't feel like farting around with it right now. If I knew it would fix the problem, I might be a little more motivated to do so, but it only seems to fix an incoming call sound issue (not quite the same as what I'm experiencing... but maybe related?).
I went ahead and updated to 5.0.4, hoping it would help, but it didn't. I've noticed that if I press power to turn off the screen/mute the ringer, then turn it back on, I can get to the full dialer screen and accept/reject the call. Also, this freeze is easy to reproduce from the dialer log. If I browse for a sent/received call from earlier in the day and tap that, it won't bring up the sim card choice (TMO or ATT) until after 30 seconds or so.
If anyone has seen this issue, please chime in. I'm at my wit's end.
I have some issues with incoming calls. Sometimes it vibrates but doesn't show any incoming call only when I have missed it afterwards. I don't know what causes this behaviour and if it is related to your issue. I'll switch from OxygenOS 5.0.4 to LineageOS 15.1 soon so I didn't look into that and I'm not going to
I'm not sure, but it definitely seems to have something to do with the dialer itself. My guess is because I'm using two sims. When dialing a call, it's almost as if the box to select a sim to dial pops up behind the dialer....
Try wiping dialer cache then reboot, go to recovery and wipe cache/dalvik and see if it helps. btw, I find no difficulty in answering phone call.

Pretty sure I tried that, but not since the latest update. I'll give it another shot!

Ongoing call window not opening

Hi, everyone.
So I've flashed the RR rom with magisk and OpenGApps on my Z2 play. Everything was working fine, but a week ago I experienced some kind of glitch. When I'm receiving a call the phone vibrates, but I can't pick the call up because it is not showing up anywhere. Similar with outgoing calls, once I press "call", the phone gives out dialing tone, but is still in contacts section without anything in notification bar. Could anyone help? This is really getting on my nerves, because I can neither pick up nor drop calls, not even talking about other things (speaker, mute, keypad etc.)
Thanks in advance

You flashed the RR 9? I had a similar problem with the gsi roms.

i have the same issue and i´m on stock oreo. i find the call appears if you open the phone app, then the "return to call in progress" dialog appears and by selecting that it shows the incoming call screen and you´re able to pick up. super annoying as i can´t see who´s calling or pickup until i do what´s written above. i cleared the phone app cache but didn´t sole, hope pie will solve this thing

No incoming call notification, no ringing

This has happened twice and the only fix was to do a factory reset. Seemingly at random I'll stop receiving a call notification and my phone does not ring. The only way I know I missed a call is if they leave a voicemail because I'll get an alert for a new voicemail. I was literally looking at my phone and had a voicemail pop up and it didn't ring or anything.
I was rooted, stock rom for years and out of the blue I started to get only a voicemail but never heard my phone ring and no missed call notification and nothing in the incoming call log. Did a factory reset, updated apps and everything was working fine on the stock unrooted rom (just in case a magisk mod messed it up). Now out of nowhere it started again, no ring and no incoming call display. The 3xL is no longer being updated and was working as normal after factory reset with the newest rom from the google website.
I would rather not have to keep doing this every 2-3 weeks because I don't know when exactly it stops working because if they don't leave a voicemail I have no idea I had missed a call. Phone is not in DND/silent because I've held my phone looking at something and just get a voicemail and the phone didn't ring or show incoming call so I know that is not the problem. If this is a widespread problem I have not seen any reports of it and a factory reset should have solved it if was a regular software issue but the same problem started happening twice now.
Edit: I've tried multiple dialers, truephone, and I've disabled Wifi calling but still no change.
E2: Ok, finally tried out a non stock rom, LineageOS. Incoming calls are working again, I didn't doubt they would after a reset because they seemed to work after the last time I reset to stock rom. I'll see how things go I guess.
