This is a little odd. The ear piece speaker is getting hot, after I did a display assembly replacement. I did everything as I normally would. What could be the cause?
Under the earspeaker is nothing what could get hot. Try to dissassembly and assembly again.
Its the front camera flex assembly, this happened to me the other day, replace cable and all is fixed. I can only assume I messed it up when removing it as I use a bit of heat to separate the prox sensor from its bracket.
