So, my devices "stock firmware" supports VoLTE (android 6). Most of the ROMs that i have seen for my device (android 7.1 based) dosen't support VoLTE. After some digging in the internet, i found out that IMS is VoLTE and VoWIFI. So i copy-pasted the apks that have "IMS" in front of them ,from my stock firmware to custom rom, doubled-checked the permissions, and rebooted my phone. VoLTE didn't work. The secret code says "VoLTE Provisioned". Am i missing something? Or am i completely wrong about this thing? The manufacturer is samsung, if that helps in a way.

it is just that volte is not supported in stock android. if you are using lineage os 14.1 then volte will break.

thank fully if ril is working in your port rom then just register play service id from playstore to google android device certification. and thus ril and volte will start working.
