i do knw wht a bixby is,u probably didn't understand wht I meant but once u hv bixby the first thing u should probably try is open the camera app and search for the bixby logo then point your camera towards and object like a watch or a plant of some ...

you are using an older Samsung device and bixby will not work on any models released before the s8 and if u want to still try rooting your device

yea exactly you can't just download bixby off of playstore are you sure it is bixby
