I think it's working great in A12 (Custom Rom). I'm not an expert and haven't tried all the tools because I honestly don't know how they function yet. but duckhunter hid working great and tried android pin bruteforce and its working.
Files attached in case you want to try.

for the kernel and module
1. Flash the nethunter op7 v4 in FKM
2. Flash nethunter op7 v4 module in Magisk
3. I put hid keyboard in /data/local/tmp and set permission to 0755. (not sure why but xbin folder is missing -where hid keyboard should be installed after flashing the magisk module). just rename the file and remove .txt
Don't blame me if you brick your phone.
