Do you use case, protector or no?

You can lift up and remove the dust with tape. But sometimes removing the screen protector will cause the glue to not stick well.
You can always lift it up and use tape but the corner may not adhere well anymore after you pull it up. That's my experience. Another trick is take it all the way off and run soap and water and wash it off. Then take small squeegee to it to remove the water and reapply. This has served me well in the past bc I can't stand specs under my screen protectors. Hope this helps.
 
Got couple of cases and a screen protector. Thinking of buying a couple of more cases. Always nice to switch out cases from time to time.
 
I recently got the Dr strange promotional case, and honestly, I think I like it better than any others. Minimal, but improved grip.
 
I still haven't managed to see the Dr. Strange movie though. Gotta wait for it to be on Netflix or something
