Left phone in washer and dryer; will it be okay?
So, I left my S3 in the washer AND the dryer. The phone was very warm and toasty, sort of like how your clothes feel out of the dryer. I checked the battery; no water except for a few drops. Wiped it off, put the battery in, checked the phone, and...
Everything was working.
Touchscreen, wifi, gps, home button, camera, audio (calling and receiving calls too) were all perfect. My phone, sim card, and microsd card are all taking a (dry) rice bath just to be safe. My questions now are: will there be any long-term problems with my phone, and should I look into getting a new battery?
Fortunately, your phone still works. However, if there are any water drops left in the phone, corrosion might occur in the near future. The worst case scenario would be if corrosion leads to short circuits.
So, I would disassemble the complete phone. Then I would remove any cable or attached part (e.g. camera) from the motherboard and put the motherboard into a bath of iso-prophylalcohol. Let it stay in there for about 10 minutes before you take it out and let it dry for a day, possibly next to an air conditioning. Let every other piece also dry next to the air conditioning. Now assemble everything back together.
I know this might be a lot of work. But it pays of on the long run. If your battery still works, I would not buy a new one.
