Last night I happened to keep my BB in some oil that had spilled on the table without noticing it. It was a very thin layer of oil. But overnight by some capillary action my BB seemed to drawn the oil in and now my display has 2 spots of oil. The display is less brighter. The phone is working fine except for the speakers. I can use it perfectly well with headphones. Earlier there was some oil discharge into the battery area which i kept wiping. But now there in none. what do i do? my friends advise I should switch it off for 2 days.
