hi ok so here is my problem. i dropped my phone in the water on a job site. i was able to dry it out then i restarted it and it seemed to be OK but then i get a message saying (SD card removed), sure enough i had forgotten to re-insert it, so i did so, and tried to restart it and it froze at the LG black screen.
And this is where i stand i can use the phone without the SD card in. I'm hoping to get some ideas as to whats happening and what i may be able to do to fix it.

Thanks
