S5 neo display light & page layouts

A

AC Question

I was running a shower and accidentally dropped my s5 into the tub. It was a small puddle, and didn'the inflict much moisture upon the phone.
However I immediately noticed I could not use the touchscreen despite the phone still playing music & the display being on. I pulled the battery & could use the touchscreen again! But, I then discovered the display won'the stay shut off when questions by the power button or by simply waiting.
Now I discover after about an hour my pages have all been reconfigured back to the factory state.
Please Help.
