Samsung A03S (A307U) Screen Replacement 

Great Video. I used this to replace the screen, and the screen worked great but ran into an issue and wanted your input. When I re-inserted the earpiece at the top of the unit, it seemed very loose, and when I had the phone completely re-assembled, the audio was not working. On visual inspection, the earpiece does not seem to be making connection to the contacts that sit over it (when the main PCB board is put back in place). Wondering if I might be missing something? Again, though, thanks for the great video.

U put back togther different ,black strep goes over ribbons
