[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] mjskraju:
It's been around 30 hours since I flashed the latest release(R3) of this ROM and here are my observations.

1) App Installations Time: It took 32 minutes for installing 29 apps(pls note I installed from backed up apk files but not by downloading from google play store). While some applications took few seconds, other applications(Google Maps etc) took more than two minutes.

2) ROM Performance: I remember people reporting sluggishness, after flashing test kernel provided by [MENTION=5075064]optimumpro[/MENTION] before the latest release, I'm experiencing the same with the R3 release with everything stock(sluggishness, apps opening & switching slowly). Note, I didn't have this sluggishness or slowness in previous release which I've also tested for a day or so. Is it because low amount of RAM available(I'm having around 850-880MB of free RAM available with no application opened, after opening couple of applications the free RAM goes around 500MB) in my 3GB RAM version of ZUK Z2 plus??.

3) Notification LED: As mentioned by couple of users before me, the Notifications LEDs are hit and miss. I tried to get the gauge of pattern of when Notifications LEDs are working & when they are not, but all went in vain. It is all intermittently even after making required applications(messages, phone, WhatsApp, telegram, etc) 'Unoptimized' & making sure 'Blink Light' option is turned on under each applications notification settings. I would like [MENTION=5075064]optimumpro[/MENTION] to give some insights on the possible causes of this Notification LED issues, I don't remember having to 'Un-Optimize' & making sure 'Blink LED' option turned on for every application for which I need LED Notification in Nougat. So, is it Google issue or device sources issue when it comes to OREO?.

4) Google Tez Doesn't Work Without Magisk: With this release of this ROM, I tried to used it without flashing Magisk or any Root application, for the reason that I don't need root, for me customizations provided by these custom ROMs are enough and I observed Magisk 15.3 to be little buggy, at least for first couple of boots after flashing with every OREO custom ROM I've tried(that's my personal observation). Any ways my point is, with out Magisk or any Root application installed, Google Tez(aka Google Wallet for Indian users) is complaining about Root, strangely!!, and I'm not able to use it. And I just tried it after flashing Magisk 15.3 and it all works well !!!. So, is this ROM pre-rooted?? [MENTION=5075064]optimumpro[/MENTION]

5) Battery Backup: With just 3 minutes of calls(yeah, you read that correct), 20-25 minutes of Wifi Hotspot(not wifi), continuous 4G data on and with the app usage that can be seen in the below screen shots, I could cross 7 hours of SOT from the time I unplugged the charger at 100% till 1% of charge left. May be with few more calls, I could've got less backup but it is what it is. Refer below screen shots of detailed app usage of mine during the reported period. In this regard a commendable job [MENTION=5075064]optimumpro[/MENTION] :good::highfive:

6) Unable To Boot: I know it is already documented, but mentioning it again, can't boot properly(need to force reboot, some times more than one time) after flashing ROM, Magisk & even after clearing caches as well(I tried to clear caches to see if it solves Notification LEDs problem). I hope this issue is addressed in the subsequent releases although this is not a big deal.

Cheers.
