My s6 fell in water capacitive button does weird tricks

[AC Question]

My s6 fell in soapy water but it was not completely submerged I tried shaking it and I also put it in rice for 2 days everything works but the multitasking button does not work properly and sometimes it is pressed by itself and also the charger sometimes loses contact

Any help is welcome
