SonoAX Hi, unfortunately your steps don’t work on the Nothing Phone 3a (Pro) anymore.
I also tried out ADB commands to reset the search engine entry I’ve found on a FairPhone Forum.
Last but not least, I also tried out running the Selection Activity of the “Search Engine Selector” app using “App Manager” with Wireless Debugging Permissions.
All without success. Maybe this saves other people some time. I have given up and am using a normal Widget now.
