In this paper, we present the results of a study of magnetotransport and quantum corrections in a 50 nm thick Cd3As2 film deposited on a strontium titanate substrate. An analysis of the results of the magnetic conductivity revealed the presence of a weak antilocalization arising from surface states. Weak antilocalization is sensitive only to the perpendicular component of the magnetic field and is well described by the model of Hikami, Larkin, and Nagaoka. The calculated value of the phase coherence length
