Yes the lag was more noticable with the 16xx software and H56 with older firmware because only 2 of the 7 cores of the cpu were been used. Also the 17x/180x software was better but still was on older firmware with H56.
When the 816G/820H came out it came with the H58 hardware and 189x software so all cpu cores were unlocked. I have not come across the 1880 here in europe so it could well be that 1880 is similar to 1890.
So H56 only 2 out of 7 cores working and H58 all cores working.
With special firmware update the H56 gets all cpu cores unlocked just like H58.

Here is a table of the software installed by part number:

Thanks, this is what I was trying to understand. I guess the press releases heavily implied there was a new SoC that had more cores. That would even be valid if they unlocked cores in the H58 but what you are saying is that an H56, H58, and H61 all have the same performance as long as you have software past a certain version?

Obviously you may not know but why did VW have 5 cores locked? In the desktop world this is how Intel and AMD sell chips with one or more damaged cores, they just block them off and sell it as a lower model. I've also seen SoC situations where cooling was a problem so cores were disabled. Do you also know if VW rewrote some of the software to be more multi-threaded or add multi-threaded code where it was just single threaded?

I installed 1941 and it didn't fix any of the Android Auto issues. It feels a tad more responsive from 1880 but not enough to be worth the risk.

What is your problem with Android auto?
I still have the old SW 1668 and I have no problem with Carplay and Android Auto. Next week I have an appointment with the dealer to recall that they are upgrading all module units because it is free.

One of two problems
1. Google maps freezes so you can't scroll, zoom or enter addresses. The quick app buttons do work though. I can unfreeze it by switching to any other app then back to Google maps.

2. The quick app buttons freeze. In this case the map works great I just can't change the view or go to any other apps. The audio app that was playing continue to work fine and I can even skip tracks if I use the VW audio menu. To fix this I have to either wait 10+mins or using the phone go to Google maps, then Spotify or an audio app. Basically unlocking the phone then using it seems to unfreeze Android Auto

This only happens using the new Coolwalk interface that is being rolled out depending on the phone and car. The image below (not mine) shows the interface, it allows multiple apps to appear at once. The "quick app buttons" are the set of four horizontal buttons on the far right of the image.

I've tried the following to fix it.
1. Beta versions of Android Auto
2. Turning off battery optimization for Google Maps, Android Auto, Spotify etc
3. Enabled high performance CPU mode on my Galaxy S23+
4. Allowing all permissions on Google Maps
5. Turning off the Samsung always on display (someone on reddit recommended it)
6. Updated infotainment to 1941

No problems at all with H58 and 1896, either with Android Auto (wired or wireless) or in fact any aspect of the rest of the car.
