Default [Q] Almost out of the "water"

My M919 GS4 was fully submerged under water for about 20 minutes. I took it apart and cleaned everything with a toothbrush. I replaced the battery.

The phone now turns on and everything seems to work except I have no 4G and the earpeice and loudspeaker do not work. I ordered a new loud speaker and a new ear speaker. I also ordered a new charger peice where the antenna cable connects and a new blackplate.

Should I order anything else?

Thanks for any help!
