I did make some changes, which may or may not fix video calling, as I can't check. Video calling with other apps works fine though. Also, it is totally irrelevant, in my view, who gets what first. I am not competing against anyone.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] anaknin:
On the topic of this

Here are my findings

ROM - AEX 4.6

Kernel - DARKMOON WITH CAMERA BLOBS

The issue appears only when the manufactured charger brick supplies more current to the phone , ie as long as the phone is below 80% ghost touch is present , but as soon as that threshold is passed the current going into the phone drops and ghost touch disappears.

MY SOLUTION - I have ditched the box supplied one and i am currently using a 5V 2A Charger from Asus which takes 10 min extra to charge up the phone but completely gets rid of ghost touch issues

P.S the phone doesn't have ghost touch issue with a QuickCharge 2 or 3 charger brick.

I installed latest jaguar and I have to say this, this is the smoothest and specially made ROM for this device.

But there is one major problem I noticed

Heavy CPU throttling - under load CPU can't maintain higher frequency for more than 2 secs. Big cores come down to 1.4ghz and little cores come down 1.0 ghz. We can't see any real world performance degradation because of snapdragon 820. The worst part is phone gets heated more even in this throttled Frequencies.

I even tried performance governor but the problem persist.

Ps- I used CPU throttling test app from Playstore. I tested on other roms they were all right.

Request - add adreno idler as default gpu governor.

Please look into this issue.

I'm surprised no one else noticed this issue.

I will stay in this rom for sometimes to see things get improved over time.

Thanks and regards.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
No one complained about throttling, because they never had it. Some mentioned heat, but I am yet to see one legitimate complaint. Overheating is when your phone goes 78+. Everything else is normal operating temperature.

You can have throttling (and overheating) only if you:

1. Put stress on the phone, while it is connected to the charger (both throttling and overheating)

2. Enabled more than one thermal engine (there are 3 and only one should be enabled) in Kernel Adiutor

3. Changed temperature triggering throttling: default is 69 for frequency and 80 for core throttling (also in Kernel Adiutor)

Any of those 3 will be greatly accelerated on a freshly installed rom.

Also, no CPU will ever hold highest frequency, unless in Performance governor.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] selvarajrajkanna:
I should have mentioned this first, every test was done on stock kernel with stock setting.

I didn't run test when the phone was charging.

As I mentioned earlier I tried performance governor but still same problem.

Only one thermal engine (default) was used.

And again I used stock settings.

Please look into this.

Thanks and regards.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
What is the temperature?

By the way, during Antutu test, which really gives a good load, the temperature never rises more than 45.

Edit: whatever 3rd party app you are using for testing may be either crap or it doesn't have permissions to properly read CPU. Look in Kernel Adiutor for real frequencies...

Read my original response, as I have added some other points.

I can safely say that with default kernel settings, Jaguar doesn't have overheating. Nor does it have anything other than standard throttling (only if the temperature rises above 69.)
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] selvarajrajkanna:
There are tons of temperature reading in cpuz

But kernel auditor shows 63 to 65
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
The battery on your screen shot is almost dead. You will always have throttling under these conditions.

I don't think it is kernel adiutor, but rather the app he uses for testing cpu loads that serves ads.

Updates

Hi can you provide update software option in the ROM instead of dirty flashing everytime?? Is there an option like that? I need to install all the apps again everytime i dirty flash.

Also the location sensor is not working properly i think. Whenever I use maps its accuracy is very low. I had to calibrate every 5 min. Other than that this is the best ROM I came across.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] selvarajrajkanna:
Kernel auditor from playstore have ads.

I used the same app on other roms and it didn't throttle this early.

I just ran this on other device yunique which is prone to heating and the device maintained higher frequency (1.2ghz) for 5 mins.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
But this makes no sense: you need to reinstall apps on clean flashing, and no reinstall on dirty, except for Gapps, which you need to flash every time.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
You need to untick 'apply on boot' in all screens in kernel adiutor and then reboot. Also, never restore kernel adiutor profiles from another rom. If that doesn't help, delete kernel adiutor and try again. No one else has this problem...
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] selvarajrajkanna:
I know how to work with kernel auditor. I uninstalled it and rebooted the device to make setting default again.

I didn't import kernel auditor settings from yunique . I compared with yunique to prove that the app I was using for testing is not the problem.

No one had this problem because no one is looking for problem in throttling (every one is obsessed with heating).

Dear dev optimumpro, I'm going to write something which you got to believe. I don't know whether you know it, but if you don't, don't think I'm mad. I've seen you once write here that volte should work only when data is enabled, that's not right, it works even when data isn't on & I can call using volte flawlessly on Jaguar itself without data turned on. Now, here's the deal, I've noticed one thing that shouldn't be the way it is. Native video calling, the option to video call in native caller & contacts app is only visible when I turn on the data.

That shouldn't be the case. On zui I could call even with data turned off. The previous phone I used didn't support volte & vilte( that's what we call native video calling, video over LTE, vilte), so as soon as I got z2, set it up, I tried video calling a friend, it worked, after it was over I noticed that my data isn't turned on. Later on I've done this numerous times & vilte worked regardless of data connection status. I don't know coding, I don't know anything about how this services work, consider I'm Jon Snow, but I know the facts & I'm damn right. One more thing, I'm not sure about this but I think that if we don't turn on WiFi calling after a clean install, native video calling option doesn't appear, now after it appears once if you turn off WiFi calling, the option to video call still remains provided data is turned on.

I've seen you ask logcat from a user on failed video calling attempt, I can give you a few more logcats, like say I'll call someone & it'll fail, I'll make him call me when my data is turned off & on. Then I'll restore my zui 2.5 nand backup, root it & do all these again, grab all the logcats & give it you.

ONLY IF YOU ASK FOR IT.

There's no hurry with fixing it, since you want to fix it, I'm just offering help.

So, will you be working on extended/long screenshot feature? I hate to see it only in MIUI and OxygenOS.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
You said you had the same throttling on performance governor, but that can't happen, because in performance cpus stay at the highest allowed frequency. You also said you couldn't see any performance issue on 1000 frequency. Try to limit the big one to 1000 and you will see lag immediately.

Your third party app simply can't properly read cpu frequency on Zuk or can't work with Nougat.

As I have said, despite some consistent noise, I am yet to see one legitimate issue with either overheat or throttling.

Let's do that after trying December build. Also, volte, as a sip service, requires data to be on and because it is implemented by Lenovo through proprietary apps, it uses data directly through IMS. Also, in the absence of data, your calls are routed through WIFI.

This feature doesn't work on Jaguar.

Dev, this CPU throttling fact this new guy is so much concerned about, I faced something like it a few days ago. So it happened that I was playing a particular game which was probably not very optimized, it was causing the device to heat up, I don't care about processor heating, it doesn't heat much, but the battery was heating up to 42-44°C which may affect its health. Those times when I played this game, I tested big cores in k.a. by resetting the times for which certain freq were used, after playing for 10-15 mins I used to check the amount of time for different freq use, I would see that maximum 2mins was on 2303, and then the times was distributed among freqs around 1400. Never felt any lags though.

Then I stopped playing that game, got bored actually. The next game I started playing seemed to be more optimized, it was also rich like the previous but didn't cause so much heating, now when I checked k.a. I saw the bigs were on 2303 for much longer time. BTW I use all default settings except I've switched to intellithermal thermal engine & switched off the other two. Now I don't play any games so I don't worry.

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] selvarajrajkanna:
Maybe you are right, the app and the kernel auditor both might have red it wrong. But I'm damn sure that something is wrong. It might be the overclock of 150mhz, I'm not 100% sure but overclocking might cause this kind of issue (experienced in 1st generation Android one). Just try the stock clock in next build (we have snapdragon 820, we can afford).

There is some thing wrong because kernel auditor won't read the frequency wrong but it did.

Maybe this is the reason why some people experience heating even I felt slight warm than usual with jaguar.

This ROM is great and I want it to improve that's why I'm reporting the issue.

Thanks and regards.

No. This won't be the case in Oreo, as it wasn't in Nougat until release 12. This was forced, because I apparently changed something in sources, and the phone cannot properly register to network, if anything above r11 is flashed clean. And I can't find what it was...

I personally like the zuk 2 stock rom as it provides custom rom feeling with those small features (native screen recording, Utouch, status bar tweaks, etc). But then clean flashed jaguar like 2 weeks back cause I thoguth it was perfectly secure for me and it worked great by the very first attempt expect gapps cause I downloaded ARM instead of ARM64. It gives 4h of sot and 8h on weekends, right now my phone uptime is 45h without any unknown reboots. Compass on stock rom couldn't trace my longitude-latitude but now it did. Not too much heating problem. Thanks for working on native screen recording. Somtines status bar icons become light unitl I pull it down and up. Installed gapps mini and works just fine. Phone is swift and sharp, I don't know if it's possible or no but if there would be an inbuilt applock or an app that doesn't use admin permission would be great. Snapchat didn't recognize the root 'surprise' but whatsapp and paytm did, maybe I didn't hide root at that time I don't remember. If you play clash of clans then when I hit the x to close the game pop-up it won't work and I have to press 3-4 times, annoys when other hand is busy holding a cigarette, I don't use any screen gaurd so obviously it's not outside problem. Flashed Dolby Atmos zip and both phone's and bluetooth heaset speakers are customizable and work great.No fc till now. Lawnchair launcher is awesom. Thanks for the fab rom.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] The.Night.King:
No need to flash Dolby atmos zip. Install Dolby magisk module from within magisk download section. Its more compatible & won't leave residue over uninstalling. Please bother going to review tab on this thread & rate the ROM accordingly that you love it so much.

Optimumpro one feature needs to be added to this ROM, because security is a prime concern. We have options to hide power menu & statusbar on secured lock screen, which is very nice, but what about quicksettings? I've disabled statusbar & power menu on lock screen but still when I swipe from the top of the screen, qs comes down, now all the toggles can't be altered but a few of them can be, DND can be toggled to get total silence & someone can get to know the hotspot to which the device is connected to.
