Hello, thank you for your review, based on which the supplier contacted us. He would be happy for you to contact him at
[email protected] and indicate the type of phone you are using. The glass is designed to be case friendly, which means its edges are aligned to the active part of the display so as not to block the speaker. At the same time, the part of the glass that covers the speaker is not adjacent to the display to avoid distorting the sound. Thank you and have a nice day, Ondřej - Alza expert
