Thats so bizarre, my Note10 plus is also the Exynos version and the only issue would be the fingerprint sensor is a little fussy. It certainly does not stutter and the signal is great.My Note 10 Plus (Exynos) had dreadful signal reception, it stuttered/jumped when scrolling down webpages & in the photo gallery and the fingerprint sensor was garbage. Other than that it was brilliant but those faults were pretty bad.
