[Realme 3i ROMs, Kernels, Recoveries, & Other Devel] M.A.P:
lineage-17.1-20201110-UNOFFICIAL-RMX1821

Known issues :

Double Tap to Wake

Encryption

VoLTE call might get stuck at hanging up (This is very rare. It only happened twice in this week for a tester while the others didn't face any such issue. If you face such issue just restart the device)

WiFi Calling

Magisk or any other root implementation for that matter (Probably due to oppo_root_check in stock kernel and also due to vbmeta being appended to bootimage which is getting skipped during repacking of bootimage)

Fingerprint not working for et512 models. Users having other sensor can use it just fine

Not really an issue but, the device codename will only be displayed as RMX1821 even for RMX1825, it is only for displaying purpose and is completely safe for flashing on RMX1825

Safetynet doesn't pass

Call Recording

Selinux is permissive(Temporary. Will soon make it enforcing)
