Such as? I'd be interested but don't know I would find any. Dual-frequency is already hard to come by and only mentioned somewhere far down their spec sheets.
I have a Pixel 6 Pro, which shows me connecting to GPS on L1 & L5, GLOSNASS on L1, Galileo on E1 and E5a, and BeiDou on B1 and B2a. Unfortunately for the GP's point, that's quad-system but still only dual-band, as L1, E1, and B1 are 1575.42 MHz and L5, E5a, and B2a are 1176.45 MHz.
Quite fun, but not surprising: all the satellites I'm picking up on L5 frequencies I'm also picking up on L1 frequencies, between 24 and 27 signals, sitting in my front room. British houses are not very good at blocking GPS, it seems.
