same thing happened to me but my screen works fine. there are just dark spots on the upper right corner of my screen. HELP! i have an iphone 5s. the earpiece is a little bit messed up. coconut oil spilled on top of my phone but it didnt affect the speakers. just the earpiece and the dark spots on my screen. :(
i think it is the bleeding LCD. If it works fine, than just use it till it works if it start showing some problem, you may have to change the LCD.
