The “Circle to Search” feature, for some reason, is not available on my Nothing OS 3.0 (Nothing Phone (2)). My device is on build Pong-V3.0-250113-1723. Does anyone have any idea how to enable this?

Yes, I’ve already restarted my device multiple times.
[UPDATE]
Guys, if anyone else is experiencing this issue, I believe it might be caused by multiple updates when setting up the phone for the first time (like jumping from Android 13 to 14 and then to 15, for example). Unfortunately, the solution is to perform a hard reset on the device. You can do this by going to “Recovery mode -> Wipe data/factory reset”.
