Dust under my glass after display repair by samsung how to remove?

That is interesting. So was this repair done by Samsung or a repair shop? I ask just because there are two ways to reapply the screen. One is without UV glue and uses just double sided adhesive. The second is LOCA(liquid optical adhesive) and that gives you a near factory finish with no glare issues. If ther is dust and it was direct from Samsung you need to take it back to the store and tell them of the defect. If it is a repair shop you can do the same, we do loca repair all the time without dust at our repair shop in Fredericksburg, Va. The double sided adhesive repair however normally has issues with dust particles getting in the phone. Here is a video of us applying LOCA so you can see.
