Screen Guard for Samsung M30s

[Blackholesun]

Can someone please suggest a good screen guard for Samsung M30s. I purchased the phone just 10 days ago from Samsung showroom and the screen guard they applied on the phone is not of good quality. Already some air bubbles seems to have formed under the guard. Don't know if they didn't applied the guard properly or it is the quality (of the screen guard) issue. The screen seems to get dirty very easily too and the cleaning results in greasy appearence (i am not really able to explain this).

Thanks.

You can use glass one or Plastic one with Proper Certified like gorilla glass, I prefer plastic one because they are more durable

Corning gorilla glass is best
