i flashed ur latest r18 over r11.1 as told and everything is working fine expect i cannot place jio to jio outgoing calls.

'jio' is a volte service in India.

You have to flash offical Indian Rom and get your Volte to work there. When you got Volte to work on Indian then Flash Jaguar then Volte will definately work.

Google apps crashing

After each dirty flash google apps are not working unless I flash GApps again..Is there any work around
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
There is no work around and there shouldn't be one.

On every rom, when you upgrade, system gets wiped and Gapps are in system. Some developers "fixed" that on some Nougat roms. This was wrong and they are not doing it anymore in Oreo. Just think about it: when you don't wipe system on upgrade, there may be leftovers from prior roms/releases, which would interfere with your existing rom.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] The.Night.King:
Serious issue

Op, I faced quite a serious issue today, don't know what caused this.

I was playing a game, xcom enemy within, its high end, its offline & no need of gapps to play also no need of patched or mod apk, original apk works fine.

After 15-20 mins of playing (battery 18%), the game suddenly closed & I was in home screen(battery 7%), no fc pop up, charged for sometime keeping device idle. Next I opened fennec f-droid & pages weren't loading fast, wasn't scrolling properly, then fennec also closed, no fc pop up again.

I went to dev settings opened running services, free ram was too low also there was nothing much on list, also the cached process list was little.

Opened memory tab in settings & saw android system was using 1.5 GB.

After reboot things got fixed.

I can confirm that its not over-heating issue, don't know about CPU, it cools fast before even I open k.a. but battery was at 40°C. But this is because I use an aluminium heat sink below my device, just keeping it touched to default back cover keeps the phone cool while playing this game, else the game gets battery to 47°C in 15mins, never experienced such heat with any other games.

The game has also been recently updated a month ago or 2 for optimized performance with sd835 and android 8.0.

I'm on stock frequency in big and little. Only changed gov. to impulse. No undervolting. Only changed thermal d to intell.. and unchecked others. Nothing else.

Screenshots attached.

Logcat & dmesg in logs.zip.

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
This has nothing to do with heat. 40 and 47 degrees are fine. Battery at 40 is a bit high, but that's how Z2 is made. Battery is sitting on top of CPU/GPU, so when they are warm, battery is warm too.

Your game takes too much of ram. 300-400mb of available ram would take everything to a stand still. With this game, when you are done, you should either kill it, instead of exiting or exit and then f/c it in settings. You can also make cleaning ram more aggressive in Kernel Adiutor, but if the game itself takes a lot of ram (which it does), the game will be f/c.

I bet after reboot, the game will be fine. But if before the game, you used the phone: web browser, video watching, camera etc., then they all sit in ram, even if exited (they never do, unless you kill them).
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] The.Night.King:
I know its got nothing with heating. But is the game really using lot of ram? On memory tab its showing 217MB only. Also I have played this game before, also played on older device which had sd410 & 2GB dd3 memory, the game glitched but never faced ram issue. Everyday I play & normally exit the game & hardly any cached process remains I've never noticed any hike in cached process total memory use, so never checked also, the game also runs no background service, its got no notification service too.

Edit : Just tested again, pressed home button, went to dev options only using 400+ MB ram, and after exiting not a single 1 MB cached process left unlike other apps.

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
If you never reboot the phone, ram gets clogged. Web browser by itself can take up to 1gb of ram. So, what you had was a combination of left overs plus the game and once ram got 90% filled, the system almost froze. Why do you think the phone always has plenty of ram after reboot. On my phone I get 2.9GM free ram after reboot.

Played it, liked it a lot, but then just deleted, don't get that deep feeling nowadays, but this offline game is cool, doesn't force you to keep playing, even saves on sdcard, no need of cloud.

Installed the latest r18 build according to instructions properly

Two things bothering me everything else works very good

1 As in screenshot why there is no simcard sign over at top in statusbar even I have both sim running

2 On 1 St day after installing system stopped responding and I have to restart it to make it work 3 times while using normal apps like fb YouTube and COC

Second issue is that one in which system requires some time to get use too I guess so after that I haven't got that kind of bug but 1st one is still there but only on lockscreen after unlocking it disappears

Not bugs or major faults of any kind but Jaguar is like one of the Perfect ROMs I have tried for our device so just pointing out some things.

It's funny that i was ignoring this rom despite it's popularity due to the elaborate op and some comments about the bugs.

I have used aex and lineage os in last 6 months which were nice but this rom is much better in terms of battery life, performance , stability and ofcourse security imo.

Battery life remained good even after installing 60 apps whereas in formerly mentioned roms it dropped as more & more apps were installed.

It has more U-touch customisation options than aex and lineage.

Has Wakelock, alarm blocker, cpu voltage control and super fast fingerprint sensor and overall system responsiveness is unmatched by above mentioned roms imo.

I just have two aluminium plates of suppose 0.5 cm thickness, I took it from a broken inverter that my father was going to throw away. I just keep the device on it with back cover, the plate absorbs some heat & dissipated it into air, acting as fin or extended surface. That's it.

Probably the game isn't optimized, may I know the game's name? Otherwise games should run laglessly on SD 820 and on a performance based ROM, it must run smooth. GPU oc may not be possible or unnecessary I believe.

Use the search function in Jaguar thread, there is a command to disable dt2w which can be executed via adb & terminal emulator but it resets after reboot, can be made to auto apply in k.a. but I don't know how.

Have you hidden magisk? Root may be the issue. Probably you guys don't use play store I believe. But use magisk hide. Also check whether you've given accessibility permission to any app, remove the permission.

Single tap to toggle doesn't work with data, but Bluetooth single tap toggle works if Bluetooth is in the primary qs pull down. Don't know about WiFi, probably no.

Jaguar is built to provide security out of the box, accessibility makes the device vulnerable to malwares & other attacks. You wouldn't have to waste so much data had you read the full op carefully. I believe your request won't be granted.

Doesn't happen to me, did you freeze any wallpaper related system app? Also check whether applying wallpaper by all 3 or 4 default methods take you to same conclusion. You can try clearing data of lawnchair or restart the device or system ui. Switching between Jaguar default themes may cause it.

Thank you sire, I'm that user.

Op, please look into this issue.

You can check about accessibility in accessibility tab in settings. No custom ROMs pass safteynet which may be cause of your trouble, to pass safteynet, rooting with magisk & hiding it is necessary. I don't know whether you use google apps.

Nothing much, just 2 plates for now. As you can see house flooring is stone, so its really cool, I keep the plates on the floor & they become extremely cool, then I place phone on one of these & play, after sometime the plates themselves become hot, then I replace it with the other plate & continue.
