Hardware 2ds cursor doesnt move where I want it to sometimes

[coolkitty]

I did get water on it. The issue is It was only a little bit of water on the screen and that around 2 weeks ago. Normally I would put it in rice but I didn't because I assumed it was fine after talking to a friend about it. now all the sudden it's not working right sometimes. I put it in rice now. could this be why it's not working right sometimes. Also will putting it in rice this late actually save it if it is indeed the water. I turned it on for about 5 seconds today after leaving it in rice last night worked fine but sometimes it works fine so no idea if its the rice I don't want to get a new one because the reason I got a 2ds in the first place was my 3ds broke and it was cheaper. I have all my drawings (have a drawing and a animation app) and game data on there. Also this is an afterthought but I think it depends on the system and amount of damage. I have an old dsi which I actually had never put in rice I just let it dry out and it works just fine
