I’m also experiencing call quality issues. I’ve been told it sounds like I’m on a train.

 

I have the same problem. Some days it is better than others. iPhone user.

 

This will not help the diagnostic but on the contrary, people are often surprised when I tell them I'm in my car as they say the sound is loud and clear. Android user (Galaxy S22+)

 

Same here, no issues with Android. If it is apple related, it may compensate for the digital key delay (unless somebody has call quality issues with Android).

 

Is there a way to reset the multimedia system?

 

Yes hold the X and the trip button in the steering wheel The two bottom buttons on each side of the steering wheel) for approx 20 seconds

 

I have call quality issues - i am told i sound very far away and in a tunnel ! lol . Pixel Pro 9 User

 

Android user, no issues with call quality whatsoever.

 

I think it's the hardware in some cars and nothing to do with phone.

There are both Apple and Android users who are finding it either perfect or totally unusable.

It's almost as if the noise cancelling microphones have been installed backwards or out of phase or something - basically my car rejects almost all of my speech and instead broadcasts -all- of the road and wind noise. It genuinely sounds like I'm in the middle of a skydive...

 

It's almost as if the noise cancelling microphones

Do you mean there is ANC on the Polestar 4? I couldn't find any reference about this. I would also expect to see the microphones somewhere in the cabin like on my previous car.

 

Hmm interesting. How can I prove that it won't be fixed via software updates and instead is a hardware issue ? As I spoke to customer services and they simply said wait for OTA updates.

I am trying to avoid to drive to Polestar showroom which is 1 hour drive away! Don't have any local to me.

Plus even then, they will most likely keep the car for some time which I cannot do !

 

They always say that. All you can do is persevere... logically, if it was a software fault, everyone would be affected.

Showroom won't be any help anyway - it's a Volvo dealer you need.

 

I've got a nasty rattle from my overhead console anyway, so might pull it down over the weekend and have a poke around.

 

Terrible call quality in my car as well - iPhone using both Bluetooth and CarPlay

 

I started getting complaints about horrible call quality the day after they did a software update to 4.2.2 for me at the service. I had no complaints for months before this update. I'm using an iphone and before the update used it in car play mode but since 4.2.2. it doesn't connect to car play so using it in Bluetooth mode. I'll try again in car play and report if it helps.

 

Ok so I tried 3 options of using Bluetooth for voice calls since my previous post and I can confirm the following experience.

First to say that major change since the update to 4.2.2 is that if I connect my iPhone to carplay, the car then automatically disconnects wifi connection and disables wifi. Since I didn't want to use carplay and prefer to have the car's own OS and wifi connection I didn't use carplay but have only used plain Bluetooth connection with the car since the update. This is when I started getting complaints about poor call quality. Since I also have an Android phone I tried the same Bluetooth connection with Android phone as well (P4 doesn't support android auto). So the 3 connection options gave the following experience:

1. Iphone using Bluetooth - horrible call quality, EVERYONE complained about terrible background noise

2. Iphone using carplay - much better call quality, no complaints

3. Android using Bluetooth - good call quality, no complaints

My conclusion is that Polestar didn't expect people with iPhones to use just Bluetooth without carplay and didn't do any work to apply ANC and voice isolation in this connection mode. This is very disappointing and I hope they will update it in the subsequent update. This is clearly possible as it works with Android phone. Also, this wouldn't be too bad if they allowed me to use carplay while car is using its own wifi and its own apps like it used to do before the update which worked fine. However, now after the update to 4.2.2 this is not an option any more and I have to choose if I want to use the iphone for calls - I basically have to completely hand over the screen to carplay and disable car's own wifi and OS. Very silly choice.

I hope this helps.

 

I’ve got call issues with my PS4. Car arrived 11 April with 4.2.2 already installed. People say there is severe background noise. Called help desk and was advised to book it in with nearest centre. Booked for 21st May. Let’s see what they say.

 

Keep us posted please!

 

I have the same issue too

 

My partner mentioned this to me when I was speaking with her via the car last week too. I've reset my phone and the infotainment to no effect. Another suggestion was turn on voice isolation, but I don't seem to have that ability based on the screenshots provided. I also think this is only since 4.2.2 as she never mentioned to me previously

 

Voice isolation is a function on the phone, not the car, and it only affects calls using the microphone on the phone so isn't going to help here.

 

Not had a problem with the BT hands free using either my S10 or S24, yet.
Might be because I spend the time just to say
" sorry, I'm driving . May I call you back later pls?
The call quality whilst using BT and parked up has been fine.

 

Have you heard the other side of he call though. That’s where the problem is… the transmit, not the receive.

 

yeah, call quality on my end is great. Thanks for the advice on the voice isolation, explains why I couldn't find it.

 

Can you please mention what phone you are using and how do you connect it? Check my posts I think this is the issue.

 

I can confirm your test results.
right now, I am using Apple CarPlay (I do use an IPhone obviously).
polestar support, state that in the next update, the issue will be resolved.

But I still do think that the call quality is not acceptable for this car. My prior car, a Mercedes, had superior call quality compared to the PS4

 

I also confirmed today that switching to CarPlay was a night and day difference for the caller on the other end. Interestingly, I didn't even end the call, I just connected CarPlay mid call and the other person remarked how much better the audio was

 

I had the same issue until I turned off Wi-Fi on my phone while using Bluetooth for calls. Made a big difference in call clarity for me.

 

MY26 on iPhone calling via bluetooth and audio quality is excellent - no issues. As a datapoint for anyone interested
