Thanks for the app. I also have found an issue with my device lg g6 dual sim. Even if I set the permission to modify system settings to the app, the setting for sim selecting: "ask first" doesn't work (I can set it, but if exit from that menu and enter back again i find the sim 1 or 2 active, depending from active sim selected from the taskbar). I tried an external app and on that I saw that the setting to ask first is working. Do you have any ideea why google phone app doesn't want to save this setting on lg g6?
