Unisoc ims

[srcenchen]

Hello.I flash the hai on my spreadtrum device. it all work without ims. It can receive and send message. It can call anyone.But it can't receive incoming calls in LTE. I try to open all the options about incoming calls in LTE. I try to install ims. However it didn't support. I install the ima spr for android 9. it not work.

I have the same issue. When I call or when I get calls, my network just switches to HSPAP aka 3G ig. I checked Phh Treble settings and tried to create an ims apn but it didnt work. Also there's button Install IMS APK for NON SUPPORTED which won't help us with the issue. I have stock ims.apk, maybe it will be helpful idk so I attach it here.
