The 2 devices matched both QTI and Samsung backends:

• qti-Samsung Galaxy S25-15.0
• qti-Samsung Galaxy S25 Ultra-15.0

Exception: multiple matching backends found: libqtibackend, libsamsungbackend

@farook-edev could help run the app on S25
@anhappdev to review the checking logic again

The check logic is working correctly, and the Samsung backend check also passed after merging the master branch with the new changes for submission. The CI for S25 has successfully passed.

@anhappdev I ran the app and got no immediate errors, although I did get SNPE for everything except stable diffusion. I'm using an SM-S931B/DS which uses a SnapDragon SM8750-AC SOC.

YES, for stable diffusion, the QNN runtime is used. That's what is designed.
