Hey Nima!
For business reasons, our suite of LeiaSR SDKs are currently no longer publicly available and are only provided to our OEM/business partners.
For Acer and Samsung product lines we have been directing inquiries to Acer and Samsung for direct SDK support.
For LeiaSR SDKs please contact us either at business@leiainc.com or sdk.support@leiainc.com with your use case and our commercial team will get right back to you!
Respectfully,
Eric
