bixby button keep falling off

Hey guys,

So a month ago i noticed that “ sometimes" my bixby and power button slightly diverge, like one end is popping off while the other end is deep down, but the whole thing was functioning good so i just ignored it.

Until recently my bixby button, fell off. And even if i stick it back , and it works perfectly, it keeps falling off from time to time. So it clearly that the button no longer have a cap that holds it inside.

I no longer have warranty for this phone, so any quick fix can i use like using glue or something?

Thank you guys.
