Thank you for your work and support for the Realme x2 community.

Did someone try it? I'm exhausted waiting for realme UI...
It's working perfectly if you go through installation process. There are very few or no bugs at all, {Mod edit}

A16 vendor Image is recommended and provided, Make sure to use that, Anyway try flashing the whole cos A16 package once to be exactly on the perfect firmware a vendor, The build was thoroughly tested on RMX1991 with A16 vendor and everything works!

I am using A.17 vendor, everything works (it is my daily driver for 4 days). I added OpenGAPPS pico.

The list of additional bugs I found:
(*) Adaptive brightness is poorly working in dark conditions;
(*) When FP unlocks the phone, the whole screen flashes on maximum brightness, then everything is alright;
(*) Battery life is not as good as it should be on this CPU and battery (and comparing to ColorOS/realmeUI). It can survive one day, but without heavy load;
(*) It is not possible to rename fingerprints;
(*) After adding gapps face unlock did not work for me.

EDIT, addition (2020-04-28)
(*) OTG did not work for me
(*) Each day battery life gets shorter, so regular reboots are needed?

Hi,

Does fingerprint sensor works as fast as on stock ROM? I didnt mean milliseconds, but overall speed
To me it works better (faster) than on stock ROMs.

I couldn't find full A16 rom file.. but I have A17 full flashing oZip file and I flashed then boom.. It booted properly.

Bugs I got
1. Battery Backup is not so good.
2. Adopted Brightness
3. Headphone sound quality (We have come from Dolby Digital?
4. Overheating when charging
5. Finger Print lighting
6. AOD, Gestures and Selinux as you said before.

5. Finger Print lighting
6. AOD, Gestures and Selinux as you said before.

1: backup depends upon user usage pattern.
2: Adopted brightness works fine outdoors, For indoors use Manual adjustment.
3: Dolby? Is a properitary software, Codecs from the xmls would be removed soon
4: Don't use the device while it is charging, I'll make throttling aggressive if the heating is high
5: Fingerprint Sensor works, The light flashes so that the High Brightness mode gets started at 670Nits and the FP sensor is able to get the perfect image of finger and unlock the device.
6: AOD is removed as it causes burnin and other issues, Gestures? Gestures on LineageOS work perfectly fine without any issues, Selinux is permissive because I can't find any good reason to write the policies and switch it to enforcing until we switch to building vendor.

Note: Refrain from terming everything you find as BUG and please do not comment if you can't provide logs and steps to reproduce the condition, it triggers my OCD

Dear users XDA-Forume, I ask you for help from me RMX1993EX I have flashed this operating system and everything works except the NFC. It is worth the last 3.3.1-19 recovery. Who works on what recovery NFC?:crying:

Send the recovery log of when you install the build on your rmx1993, NFC has been tested and comes out to be working on Both 1991 and 1993, Make sure you are on latest TWRP that identifies your device as 1993 anyway the recovery log should help identify what's going on, Before that

Try following these steps

Download recovery from Download this zip here and extract the recovery.img & flash the recovery image via fastboot (RMX1993, RMX1992, RMX1991)

Download the full package from only RMX1993
Reboot to Recovery, Wipe System, Data, Cache, Dalvik's Cache, Data
Flash the downloaded file (If the regular flashing doesn't work, Rename the file to RMX1993_A18.zip and proceed to flash it)

Then again flash the LineageOS build and Gapps
Again move to wipe menu and wipe internal storage.

Once wiping is done, Reboot and check NFC

hi
i have rmx1991 but with real ui android 10 installed
how to flash vendor image to downgrade to android 9 ?using fastboot?if so do i have to unlock bootloader and what is fastboot command to push vendor image to phone?
thanx
Of course you need unlocked bootloader. This is the first step. Then perform downgrade (keep away from selfmade fastboot images, some folks had bricked their phones using them. Moreover, if you are inexperienced). Then install LOS. To me downgrade to A.17 with it's vendor was good enough, everything works alright.
