Pixel IMS
Das hat Google im letzten "Sicherheitsupdate" unbrauchbar gemacht 
.
Es wurde allerdings eine neue Möglichkeit entdeckt 
:
ZitatAlles anzeigenI decompiled the apk provided by @vvb2060 and found that it only sets IMS enabled for the default voice call SIM. Since I need to enable VoLTE for both active SIMs, I made an app with simple UI that can set it for active SIMs individually.
If you need it you can download it from https://pixeldrain.com/u/8wi3ZVbj.(Edit: please use the new version below)
The app was originally made using the same method as Pixel IMS because I want to set all the overrides I need with one click after a system update. However the method is not working as of now, so I updated it with the new method (can only enable VoLTE) the same as @vvb2060's apk, thanks to them for providing a workaround quickly.
Update: new version with the bypass method, supports enabling 5G/VoNR/VoWiFi: https://pixeldrain.com/u/LHybJsVF

ZitatInsight from @vvb2060 regarding the block this time for Pixel IMS:
(Original, in Chinese) Google的安全补丁的实现很奇怪，明显是直接针对Pixel IMS，而不是修复shell能够修改运营商配置的问题本身，其实我很担心目前的对抗会导致 Google 最终移除 shell 的 MODIFY_PHONE_STATE 权限来正确修复这个问题。但是，即使我什么都不做，Google的漏洞赏金计划也会鼓励安全研究员上报被绕过的安全补丁，因此我对未来情况不是很乐观。
(English Translation by Google) Google's implementation of the security patch is strange, clearly targeting the Pixel IMS rather than fixing the shell's ability to modify carrier configurations. I'm actually worried that the ongoing backlash will ultimately lead Google to remove the MODIFY_PHONE_STATE permission from the shell to properly fix this issue. However, even if I do nothing, Google's bug bounty program will encourage security researchers to report bypassed security patches, so I'm not optimistic about the future.
ZitatHi everyone, patch v2.1 supports adding VoWiFi to the network name.
