Hi @jklqw,

Thank you for the report and the screenshot.

I tried to reproduce this issue on my end using a Samsung Galaxy S24 Ultra, but the GPU mode worked correctly for me with the DeepSeek and Qwen models.

This suggests the issue might be specific to the Samsung Galaxy A55 or its specific drivers/GPU architecture. GPU delegation in LiteRT can sometimes behave differently across different chipsets.

Could you please provide a Logcat when this issue occurs? This will help us investigate the issue closely.

Thanks!
