Dead pixel

[Subzero355]

bought a galaxy s7 edge 2 months ago and now spotted the dead pixel on the top left edge side, went to the service, they said they will not replace the phone and only replace the display, but the question is, is my phone still gonna be water resistant after it's opened up?

depend on whom gonna open it up
if its authorized person from galaxy yes it will be water proof but if its someone else i doubt it

Experienced hand will do it nicely..
