  In some recent experiments [A. J. Bestwick, et. al., Phys. Rev. Lett. 114,
187201 (2015), Cui-Zu Chang, et. al., Nat. Materials. 14, 473-477 (2015)] it
has been shown that in observations of the quantum anomalous Hall (QAH) effect
the longitudinal resistance $R_L$ increases as temperature $T$ increases, while
Hall resistance $R_H$ loses its quantization with increase in $T$. This
behavior was explained due to increased thermal fluctuations as $T$ increases.
We show that similar effects arise in QAH samples with quasi-helical edge modes
as disorder increases in presence of inelastic scattering or otherwise even at
temperature $T=0$.
