Samsung device type with highHO interruption time

[incoincov]

Hi experts,

I've seen FTP session lab test results done Samsung mobile showing high HO user plane interruption time related to IRAT. I am very interested in the exact type of this Samsung.
It's written during these lab tests the "other mobiles" show less than 50-60ms HO interruption time? Is it realistic?

I'd appreciate highly if somebody can share some related experience.Thanks i advance!
