Is it the spray that comes with or really water? I used to work at Best Buy and have done tons of Zagg installs and never once had liquid get inside the device. That being said they also recommend that you leave the device off and let it set for 24 hours after install. The liquid they give you is not water and should not harm the device if any did really get in, just remember to leave it off and not touch it for 24 hours. Your device should be off anyway while doing the install. If it is water turn off the device (which if you are doing the install should be off) and I repeat DO NOT TRY TO TURN ON THE DEVICE. Then let it sit in the sun for a few days. Then make sure you can't see any water and see if it works. Hope this helps and good luck.
