[Google Pixel 2 Questions & Answers] nightfly0815:
Hi I own a pixel 2 xl. I live in Austria. My provider startet the volte support, but just for some samsung mobiles. I read that just phones worked who are bought directly from the provider with a branding. I talked with the support and the activated the volte for my telephone number. But when I look into the hidden menu *# *#4636# *# * then the volte is grayed out. It´s not possible to switch the settings on. A reboot of the phone doesn´t help.

I read in an German forum that someone changed the ims file from a unsupported samsung phone and activate the volte at the unsupported phone.

Where is this ims file located in android p? I know root is necessary to access this config files. Or is there an other workaround the activate the volte on pixel? (I read that for the one plus mobiles exists a workaround with the oxygenos)

This is the code from a working Austrian ims customer.xml
