Thanks for explaining how it is! I see now its probably better than what we could achieve solely by kernel manager so it makes perfect sense.

I've already flashed that patch. I don't feel like its heating much in normal use after rom settled in.

I see alchemy kernel is also 3.x, I wonder why not 4.x? Are there no available that work with android 11 or are they worse than 3.x?

Also not really a big issue but seems like I can't configure u-touch button to run custom application. For example nothing happens or appears when you go to:

Settings -> Buttons -> Home button -> Long press action -> Select application

Same when trying to assign application for other "buttons" there.

EDIT:

Is there a way to disable dark mode in battery saver mode? I'd rather have dim white background than cranked up dark background that is hard to read and most likely still uses more power on our device.

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] EtiamNullam:
I appreciate your help. I ended up with disabling battery saver completely.

I'm currently experiencing a problem with sound volume. Every time sound is starting, like incoming notification or start of playing some media, at first volume is high (normal) then in a split second its cut down to about 20-40% of volume. Seems like there is some strange volume normalization.

Its especially annoying for notifications as many of them can't be used or sound very weird with fading off volume. Notification will sound normal (albeit quiet) when there is for example some music playing so I'm pretty sure its just some bad volume normalization.

I see it might be some kind of attempt to prevent "pop" when speaker in Zuk engages, but it goes in the wrong direction. Making pop loud but actual sound quiet.

Tried increasing gain in kernel but that's not a way to go as there will be loud spike at the start.

I hope its clear enough and there is something that can be done about it.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Pranav Temkar:
Yes we known this sound issue has been with us and we are trying to fix it

Till them you can use viper / dolby
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] EtiamNullam:
Sadly I was not able to achieve much using Viper :(

Anyway I've experienced a minor issue that I don't see mentioned anywhere:

Call recording seems to have very low quality. I've never used it before so idk how it should sound but right now its like recording from the first moon landing. At least call quality is good.

I hope it helps you get everything right. Keep up the good work ;)
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Pranav Temkar:
For call recording change quality to aac

Amr-wb has bad audio quality
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] EtiamNullam:
Okay. With AAC it sounds a bit better. At least I can understand the words. Thanks.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] EtiamNullam:
There is no deep sleep while connected to charger but not charging due to 'smart charge' causing ~15% of battery drain per hour. I think this is very stressing for battery longevity.

AccuBattery stats for 'smart' dischargee cycle:

^Note: 0% deep sleep.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Pranav Temkar:
Thanks for the graphs it was better in understanding the problem, will surely look into this deep sleep issue ✌️
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Pranav Temkar:
Could you please tell me on which rom is deep sleep working while smart charging on our lenovo z2 plus ?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] EtiamNullam:
Sadly from the roms I tried this is first rom where smart charge works at all. I only wish it was better.

Maybe our device is not capable of proper 'smart charge' at all but I still hope it can be fixed somehow. Still better than nothing I guess.

I think there is some external solution for 'smart charge' which will toggle physical connection to device depending on power draw but that would also disable data connection and USB tethering if used.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Pranav Temkar:
I don't think so deep sleep may work in smart charging for zukku

If you find a rom which has working deep sleep in smart charge on our beloved zuk then please tell me

Btw normal deep sleep without smart charge is working perfectly 😌✌️
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] EtiamNullam:
Sad. Lets keep track of other roms that advertise 'smart charge' on it. Maybe someone will find a way to do it somehow ;)

Yeah when not in charger deep sleep works pretty good. 90%+ of screen off. You can see that on the graph I posted before too ;)
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Pranav Temkar:
Btw my xtended had smart change too the trees are same there hence i wanted a different tree rom to check if it works there on different tree.

And yes i agree deep sleep on normal is picture perfect in your graphs.

Hang on next build we will fix many se denials which are spamming in logs this will help reduce heat in rom 👍
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] EtiamNullam:
Cool. Will it be required to clean flash next builds?

I've tried xtended xr and havoc os that both advertised 'smart charge' but on havoc OS it was not working at all and in xtended xr I had other issues before getting to 'smart charge'.

Thanks for your hard work!
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Pranav Temkar:
I guess havoc had working smart charging before but then the maintainer reverted it and it will not work after its being reverted

You can refer his trees here

So it may be working in older version of havoc which were released before this revert
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] EtiamNullam:
Well I'm sure he had a reason to revert it. I think what we have now is still better than nothing at all.

I wonder what's better for battery though.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Pranav Temkar:
Stay tuned guys next update will have huge optimization in kernel, @ZyxxeZ is working hard to give best sot out of our zuk, also we are working hard to fix se denails which are spamming in current build

Most of them are fixed and has made a huge impact on sot now

Would love it if the low sound problem is also resolved. Right now, this is the only reason for which I've to keep my phone rooted.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] elmarks:
Good work.

I've been using ArrowOS since version 9. Now I installed this version and for me it have the following problem: i have tested navigation on TomTom and Waze and the GPS signal keeps floating, on and off, on and off... I can barely follow a route.

On previous Arrow10 i didn't have that.

Anyone else experiencing something like this?

baseband:1.70664...

Regards.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Pranav Temkar:
Gps works completely fine as it should on waze too it locked location pretty fast and was not floating, i was using google maps and navigation worked fine never lost gps

Below i have provided gps test result too you may have a look

Make sure wifi scanning and google location accuracy is enabled under location settings
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] elmarks:
Ok thank you! were both disabled, now everything is fine
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] blueman24:
I've been using this rom for the past few week and I have to say, the battery life is really good. Great job dev!

The only problem while installing was finding gapps with setup wizard that work. I tried Nik gapps but the base version does not have setup wizard to restore backup. Tried the higher versions and the rom won't boot with them. Tried mindthegapps and again, rom wont boot.

Finally got open gapps nano test version and although it also force closed once, i was able to setup the phone successfully.

So I have a suggestion for dev, if can we get a gapps version? Does not even have to include everything only play store, phone, and messages is fine.

Also, being able to get navbar and disable hw button without required to root would be great bonus.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] atulda.1985:
Works fine for me with nikgappps full version
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Pranav Temkar:
I understand the need of navbar toggle switch is very essential for a legacy device, currently what is the scenario i will explain now most devs have new devices which dont have hardware keys so there is no point to add that navbar switch if you all would request this feature in the arrow os support chat then surely they will look forward into this

I can link you the telegram channel you can raise this feature requests there

Also i am not allowed to do any modifications to the source i can only improve device side things so you could ask there maybe some dev will add it in source which will be profit for everyone

I am having an couple of weird issues after flashing magisk patched boot image(ver 22.1). On first boot everything worked fine, But after installing viper and rebooted my recent apps not showing anything even though they are in memory and QS tiles won't expand. I tried uninstalling viper, magisk and re-flashed original boot image. Even flashed the whole zip without wiping data. Nothing resolved the issue.

Edit: Even the notification panel is not working. No notification received, But notification sound comes and dot appears on app.The Home button not working to minimize the app but back works, but gesture works even though you disabled gesture support.:D Mostly weird things happened. I wiped all partitions except data and flashed the zip again, Now everything is working fine but why these issues occurred is still a mystery.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] :
Hello,

When will the next update be released?? Eagerly waiting for it 😋😋
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Pranav Temkar:
Soon
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] EtiamNullam:
Sadly on top audio "normalization" bug I encountered another (maybe related?) where I lost all audio. Not sure if u can trust this rom if you don't want to miss important alarm or call.

I hope it was one time only (and only for me?) or will be fixed in upcoming update ;)
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] :
Conversely, I clean flashed the ROM a week ago and since then, my sound output is "normal". I do not have to do any kernel tweaking or anything. Strange.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] EtiamNullam:
It's more likely you don't notice the issue. I also use this rom with no audio kernel tweaks. You can easily tell if there is a problem by playing some music. Just play it a bit, pause, wait a few seconds and press play again. I'm sure you will notice normal volume (loud) at first which quickly reduces to be below nominal. Do it a few times. Or you can play a notification few times in row to see how sound recedes. Or you can check how the same notification sounds like on a another device.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] :
Your reasoning is poor fam. I literally have used this rom since initial april and have replied on this thread regarding "low sound". When I say that I'm getting " normal" output, I MEAN "normal" output.

Although, it seems that this'll be temporary till I do one more reboot.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] EtiamNullam:
Well if you had this issue before I'm sure you know the best if its gone or not.

Why do you think its temporary until next reboot? Have u installed or skipped SELinux policy fix? Did you root your device?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] :
Yeah, This time while clean flashing, I installed the selinux zip before the "first boot". Then, I went on root and edit build.prop to get the gestures working. After that, I unrooted the rom. So, all in all I did 2 reboots only and the sound issue has managed to survive those.

I'm sure you'll see as well that the speaker sounds normal in the first boot and then, when the system settles, the reboot will kick in the speaker issues.

Is low sound issue after multiple reboot fixed?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] :
Rom works like butter. Initially, battery was misbehaving as in after reboot, battery % drops from 40 to 8. But, after I forcefully dropped it to 0 and charged to 100, I can't seem to find any problems.

Also, after about 20 or so reboots, sound is still normal so🤞🤞about that.....
