you are in the nokia 6.1 plus tread, you should find the p8 lite tread if there is oneI am interested about the "double tap to wake" feature. I want to know what is involved or needed to support it.
Currently running Lineage 18 in P8 Lite 2017 and wondering why there's no such feature, or how should I try to get into it.
Double tap to lock, in the other hand, only works from taskbar.
Custom App Launcher has tap to lock (which is faulty by design).
I had such double tap for on/off since my old LG K8 and I really miss it on every phone I've see later.
all the ui related issues or Lineage OS specific features comes from rom source side ( Lineage OS Source code side & you can follow their GitHub organization for progress ).
I finally figured out the issues, I was flashing community vendor after flashing lineage 18.1 i didn't knew the zip contains vendor, everything is fine now thanks and many thanks to the dev @Raghu varma
