  We present global Schauder type estimates in all variables and unique
solvability results in kinetic H\"older spaces for kinetic
Kolmogorov-Fokker-Planck (KFP) equations. The leading coefficients are H\"older
continuous in the $x, v$ variables and are merely measurable in the temporal
variable. Our proof is inspired by Campanato's approach to Schauder estimates
and does not rely on the estimates of the fundamental solution of the KFP
operator.
