    Hello there,
    Anyone managed to reactivate VoLTE option after the OS12 update?
    I tried with the old reliable method, but either the logkit and the engineering mode failed to install for some kind of "version conflict" issues...
    Is there any way to get back the options without rooting the device?
    This is the worst problem arrived with the new update... And there are a lot to choose inside this os version.
    Thanks to everyone who could provide me some help.
    Bye.
