Thank you for this awesome rom! Running pretty smooth so far. Almost flawless! Just a couple of issues for me... No pen support, kill app back button in developer options is not working, no always on clock display on lock screen... Some of the good stuff... WiFi calling works! No Chinese crap! Yay! Battery life indicator for Bluetooth is back! push notifications work great!

Awesome rom using it now thanks

Thank you for your hard work and this awesome ROM.
The only issue I have so far is the inability to make calls. Whenever i attempt to make a call the phone just hangs up.
In some cases I cannot receive phone calls like the ones from banking apps to verify the users identity.
Probably something went wrong in the installation process.
I would like to know if anyone is facing the same issue before attempting to do a full reset.
Cheers.

Got it working. Very very pleased to have rr on mate 20x. I installed magisk using open Kirin website instructions. Where it says 'fastboot flash ramdisk patched_boot.img' .... I flashed to ramdisk_recovery, and have to do a button bashing combination when phone boots to get root. If I don't hold buttons, when phone boots, it gets stuck on home screen with a message displaying.
Did I flash patched image to the correct partition?
Thanks again.

Calls working great for me. Make sure when you reinstall you do the recovery partition correctly or you will have errors

First thanks for getting this rom released for our phone!!
Regardless what I have Preferred SIM for Calls set to, the prompt for what SIM to use when making a call always pops up. I like to have it set to my SIM1. The settings for Preferred SIM for Mobile data and SMS messages does work but they don't have an Ask every time option. Not a deal breaker but would be nice if it worked properly.

Is there any legit alternative to huawei's password vault that will work on this ROM? I want the phone to remember my password for apps that requires logging in so it's easier.

I got it working after flashing a more recent recovery_ramdisk and a factory reset.

I have a t mobile lite icon and and a lite on icon in the pull down bar. Are they the same? I was tricked in to thinking I had WiFi calling. I have WiFi calling enabled to WiFi preferred but it actually isn't working. Any suggestions to get it to work?

Can I install on EMUI 9.1 beta? Thank you.

According to the instructions on openkirin homepage no. Only 9.0. To downgrade I used EMUI flasher and a previous zip file I had. After that just follow the instructions.

Im interested on how big is the performance gap between stock and custom rom on our mate 20x? Antutu Score? Battery SoT?
I still can not find any Youtube review regarding the latest OpenKirin ROMs. Can someone please enlighten us by uploading some videos of this awesome milestone.

I got Antutu score of 270007 just now on my AL00 (China 8/256gb) version of this phone. My SoT isn't available at this time.

Will OTA work when there's an update? When I go to Settings>System>Advanced>Updater, first it states Last checked: December 31, 1969 (4:00 PM) and tap refresh I get The update check failed message at the bottom of the screen.
