I had my phone with a can of spray sunscreen and it appears that the can emptied itself at least a little bit into my Galaxy S2 (AT&T) and now the screen is not working. The internals seem to be working fine and I get sounds from notifications and everything. I bought this from the AT&T store with a warranty, will this apply to the warranty? Also, I can connect it to Kies and it recognizes my device and everything, but I cannot get pass the locked screen because my touchscreen isn't working. Is there any way that I can get past the locked screen on my computer, or does it have to be done on the device itself? I would like to backup all my files.
