Protective glass layer

I want to use Android pen with the Leia pad for sketching. Is there a problem with putting another layer of gorrilla glass to protect the tablet?
Is there a brand that would fit well?
Thanks Brian

Hello Brian:

Thank you very much for asking us.

Leia does not recommend air glass or vinyl screen covers on the Lume Pad if used for sketching/art with a passive stylus.

Best,

Eric
