With overclock on?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
I think car bluetooth is active even if the engine is off.

Battery drain: You need to know which app or apps are doing this. One example that I had: if your web browser is open and on a site that has comments, that java script that alerts you of every new post won't let the phone sleep or be idle.

There is a fork of kernel adiutor on fdroid. It has ads removed, as opposed to disabled, and it is regularly updated. Afwall is for November and it has more features than the original.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] MtBlackstar:
Yes

Overclocked or not the heating won't be an issue it would only get warm for a few minutes if u don't

Use the device for a few minutes everything would be normal.

And yes if you overclock a device it will produce heat.

But here it is negligible .

Do note heat will come to any device if u use it continuously like 6 h straight like I do on my holidays.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] MtBlackstar:
This is my normal usage temp .

Used the phone for reading and Spotify

For those who have doubt for overheating

General normal usage no problem.

For Heavy usage yep its a godamn phone what do you expect it has let the heat off somewhere

And the temp during heavy is within limits not over 70 and 65 at least for me.

My instructions said to change vcur only and not to touch vmax/min.

Also, replying to your youtube skipped frames: first, why would you watch a video with more than normal speed? Second, if local videos don't have the same behavior, then it is your internet connection or youtube app you are using. No video with 1080 resolution would play without glitches over wireless internet.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] pipyakas:
But if you change Vcur only, then at some point the phone would automatically re-adjust it anyway. And still, you cant save that edit alone at boot

About youtube, I usually watch videos at higher speed mostly because I can still keep up with what's happening, and watching at 2x speed saves time (a csgo match would be cutdown from 60min to 30min for example). I dont have any other device or app to test on but another user also report that twitch at 2x speed stutter as well :rolleyes:

And just for fun, a 4k60 hevc video would also have visual lag at any higher speed, but in that case it would obviously be hardware's horsepower limitation :eek:

edit: so I tried to save a video to offline viewing in youtube to eliminate the internet problem, and yep, the frames are still dropping even at 720p @2x speed. I cant view the video in any other player since the format is proprietary to youtube

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] pipyakas:
actually during heavy usage global undervolting works somehow, maybe due to the phone not trying to deep sleep which cause the reboots

I was able to maintain -60mv undervolt during a 3d 60fps game without having crashes and reboot, but still have to manually dial back the settings after playing
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] MtBlackstar:
That's a new info thanks how much heat is reduced by doing this during the usage

You just need to reboot for getting default values no need for manual dail back
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] pipyakas:
well manual dial back = adding 60mv back globally, so not much of a hastle

without a constant and repeatable load, I cant make sure of how much undervolting actually helps in terms of thermals

as for the youtube thing, I downloaded 3 more quality of the same video - 1080p60 vp9 codec, 1080p60 h264 codec, and 720p60 h264 codec

all of them suffered from some level of frame skipping, but not as bad as the youtube app, and the visuals are still in pace with the audio

Guys what's the need of under volting? BTW till now I've never touched the thermal configs of Jaguar. Should I apply intellithermal and turn off others? If so, then why isn't it enabled by default? Dev or anyone's help would be appreciated.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Arguably, if you reduce voltage a little bit on higher frequencies, you are supposed to have less heat.

Intellithermal is a different temperature control engine. It is an option, the same way, as with other governors. Some prefer different governors based on the usage. But on boot, you will have default. The rest is up to you.

RE: heating.

There is no heat issue on Jaguar. 55-65 is a normal temperature under load.

Just remember: never stress the phone, while it is connected to the charger. Phones are not laptops in that, even if you are charging, the phone still gets the current from the battery. So, when on charger and under load, your battery is being charged and discharged at the same time. Apart from killing the battery this way, you are unnecessarily stressing CPU and GPU.

How to change the songs from volume keys when the screen is off ??
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] The.Night.King:
Yeah bro, agreed. The ROM doesn't overheat. Also I never use while charging. If I have to use it for 1min in middle of charging for some emergency, I pull out the charger, use the device, then replug. Its like INTELLIPLUG for human beings:), we should take care of our devices which I believe I do. BTW thank you, the ROM is immensely satisfying.

The heating recommendation was for others, who say 'overheating.'
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] The.Night.King:
Oh. I thought you were recommending me:). I'm using Jaguar for some time now, its cool. I mean technically. Recommendations are for noobs.

I'm yet to reach that level, currently I'm at ultra legendary noob stage.:D
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
At the moment, you can't. The feature that I thought was this, turned out to be forcing media volume by default, instead of notification.

If you don't have any frame skipping at normal speed, that's they way it is supposed to be. Speed changes will inevitably result in quality glitches. By the way, how is it when you play youtube videos in a browser?

On my PC, I always have frame skipping on wifi at 1080, but those totally disappear, when connected to ethernet.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] pipyakas:
I only use chrome so youtube on the phone is playing fine in browser. On PC though, I only have a 4 years old laptop w/ an ULV dualcore CPU, so even 1080p60 at 1.5x speed drop around 15frames/sec, while 2.0x speed drop ~ 20frame/sec - but still no where near 90frame/sec like 2x speed on the phone :eek:

The funny thing is, back to 1.5x speed result in perfect playback, and in 2x speed everything else is still buttery smooth. Seeing Youtube's UI smooth animation conflict as hell with the ultra choppy playback :eek:

---------- Post added at 08:43 AM ---------- Previous post was at 08:31 AM ----------

The rom may not exactly "overheating", but thermals really can get better. For a while now I realize that I can maintain a -60mv global undervolt as long as the screen is on - turn it off for 5s at worse or 1min at best and the phone would reboot (or as long as the phone doesnt deep sleep, since if music is on then it can still stay alive). So maybe undervolting in its current state doesnt work with deep sleep, but it can be done (seriously coming from older snapdragon devices the voltage control on this device is so confusing :eek:)

Also, AKT profiles has reached its final - eol state and work quite well, in one of the screenshot at #2 post show that you implemented it into the rom at some point, might worth taking a look at it again considering some battery saving profile help reduce heat and battery drain a lot while still keeping the device responsive for normal usage

I have two sims in my device. One is lte and other is a 3g network. I would generally use the LTE for everything. But yesterday I tried to use the data from my 3g sim as changed the option in sim card my LTE sim suddenly started showing emergency calls only. All the options of LTE went to 3g including volte option . and can't connect to internet via 3g even after turning the cellular data on.

Can you give an additional option askeverytime for preferred sim forcellular data

Like in preferred sim for call?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] ashwath230:
Let me answer you for that VoLTE drop and going to emergency, well Jio is only 4G and when you switch to other sim for internet it goes to 3G which Jio doesn't support.

Thank you
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] MtBlackstar:
Brother

Only one sim tray supports 4g

My sim 1tray was 4g which is jio

Second would naturally be 3g

So I just switched the preferred sim for data to my 3g sim so why would the entire settings be changed as it only needs to change the data sim not the band of sim.

!!

Thanks for rplying
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] MtBlackstar:
All right. Here is a way to disable double tap to wake. It is a terminal or adb command. You have to be root. So, either in terminal or via adb do:

su

echo '0' > /sys/devices/virtual/touch/tp_dev/gesture_on

In adb you just have to add: adb shell and then the rest of the commands

This won't hold on reboot. So, if you use any app that executes scripts (actually you can do that in Afwall), you can insert that script and it will be executed on boot...

Hi All,

I updated to latest R17 (as given in Post, dirty flash), however, i had to reinstall GApps as they went missing after update. Did I miss anything..

Moreover, my phone goes in DND by itself, can you please let me know what should i check?

Everything else works fine, the only problem is I was using Pixel Launcher, but as GApps were missing, i lost entire customized screen/s.

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Kiranbhand1:
If you came from another ROM, you have to clean flash R11 boot it up without flashing anything on it.

Boot it up, use it for 5 mins, then dirty flash R17(don't wipe anything) flash gapps flash magisk, you are ready to go. Boot it up. You will not notice a single issue.

But if you were using r16 and it was working fine for you then you can dirty flash r17 on it. And then don't forget to flash gapps after flashing r17.

U add api 3?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] lav_2205:
Yes I'm aware of that so I followed the same steps as mentioned. To give you an idea, here's what I've done:

The phone was running r16 with all the apps crashing randomly.

Then as per Optimumpro's suggestion, I tried to look for accessibility access for any apps but couldn't find any.

Later I though its better to perform a factory reset so from the Backup & Reset screen under settings, I chose factory reset.

After reset, all the apps were erased but the internal storage still had all the files (media) intact.

Then after reset I just flashed r17 without wiping anything.

After booting I couldn't find any of the GAPPS so once again I flashed r17 + GAPPS

Everything is back to normal except the cellular network

Under Settings > Sim Cards > SIM 1 & SIM 2 - both are disabled

If I try to enable it say cannot activate.

However, strangely it shows signal bars for both the SIM Cards

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
If you did factory reset, it is the same as clean flash. You had apps crash on r16, because after flashing Gapps you didn't reboot before flashing Magisk.

So, now you need to do r11 first. Just follow directions.

The more I read you saying this about Google, the more i'm willing to try to live without GAAPs.

I've come to realize that the biggest issue would be the Google Framework. The main apps I use from Google are Drive and Chrome. Do you think its possible to keep them without having to install Google Framework or Play Store?

Also, about JAGUAR, so far so good. No complains about it. My country does not support VoLTE so i'm unable to test it. One thing i could not find in JAGUAR is to prevent poket dials by using the proximity sensor to avoid screen wake up by touch or power button. That is a cool feature to have.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Volte works fine. Also, if you disable ambient display in the main menu and in display menu, you shouldn't have any pocket dials and double taps would still work, as well as home button, but if you have swipe or pin as screenlock, you won't have any false dials.

If you can access google drive from your computer, you can access the same from you phone's browser. You'll just have to enter your credentials in browser. I am not sure about chrome, but chromium should work as any other browser. Think of this way: on your PC whether windows/linux/apple, you don't need an account to use the device, but you can login to any site with individual credentials. Google is a piece of s*it company. Their engineers are grossly incompetent and those who are not are given very narrow responsibility so that one doesn't know what the other "pro" who sits next him knows or does.
