Dropped my Samsung J3 in water and keeps booting into Safe mode?

So basically... I dropped my Samsung J3 in the bath. I immediately fished it out, took the battery out, and carefullly dried the phone and battery with a towel. I left them for 30 minutes wrapped up in a dry towel.

About an hour later, I put the battery back in and turned it on. Everything seemed fine, besides the power button not working and the theme I was using being suddenly gone, before the phone turned itself off. Scared, I removed the battery and noticed water droplets that weren't there before. Now impatient, I put the battery back and plugged it in. When the phone turned on, my lock screen picture was gone, the touch screen wasn't working, and the battery was 0%.

I took the battery back out and returned to my tasks. About one more hour later, I turned the phone on again (It started itself on Safe mode, strangely enough) and the touch screen worked again- although it didn't recognize 1 out of 5 touches. When I plugged the charger in because it was at 5%, the touch screen wasn't working anymore. I left it to charge. What should I do?
