I own a samsung gravity and yesterday night, some of the buttons stopped working. I took the battery out and left it out overnight, because I thought there might be some water damage. But this morning when I put it back in, the buttons that werent working last night started working, but now other buttons wont work. Like, the number 4 wont work, and I cant even get into my phone because thats a number for my password. Right now, its sitting in a bag of rice, with the battery out. The phone works fine, its just the buttons. I really dont know what to do, and im sad. :(
