Hi. Is it possible to support Android 8? Asus Zenfone 3 (ZE520KL) supports VoLTE, but its latest OS is Oreo.

Thank you!

As per Google Android Source, it should be possible to have Carrier Privileges working from Android 7.1 onwards. But from Android 9 onwards there is a different implementation of IMS Service and I am not sure how compatible it is with Carrier Configuration changes. I had tried to support more devices by extending this implementation to Android 8 atleast but was not possible due to method and libraries not compatible with older Android version.

Pity that I'm not familiar with Android programming. Zenfone 3 (ZE520KL) supports VoLTE in various carriers, including three carriers in where I live. It would be nice if I can test non-ipsec IMS call on it.

There is some good news. I managed to support Android 8.0 and above devices. Please try it out on Android 8.0 device. I dont have any Android 8.0 device to test. Please let me know how it goes.

Btw, you wont see Carrier ID in Android 8.0 device as the API doesnt have that function

CoIMS on Zenfone 3 showed "App does not have Carrier Privileges" while the same SIM card on Mi 9 Pro 5G had carrier privileges. I can ship a Zenfone 3 to you once TW recovers shipping to DE, if you want :)

herlesupreeth commented 4 years ago

oh is it. Did you try the latest version v0.9? (i published some fixes for Android 8.0 and 8.1 devices)

miaoski commented 4 years ago

I might have to wait for a while. Currently my Zenfone 3 (Android 8) still sees v0.8 in Google Play.

herlesupreeth commented 4 years ago

Did the v0.9 of the app work on Zenfone 3?

miaoski commented 4 years ago

No. It shows "App does not have Carrier Privileges". I was using the SIM card that I had put in Mi 9 Pro, which worked with CoIMS 0.6. However, I guess it's OK not to use CoIMS on Zenfone 3. I have set the following properties in adb shell and VoLTE is enabled.

persist.dbg.ims_volte_enable=1
persist.dbg.volte_avail_ovr=1
persist.dbg.vt_avail_ovr=1
persist.dbg.wfc_avail_ovr=1

Then I would like to close this issue as I test on Oneplus 5t with Android 8.1 and it worked. Please feel free to re-open this issue if issue arises again.
