  Motivated by the recent resurrection of the evidence for an eV scale sterile
neutrino from the MiniBooNE experiment, we revisit one of the most minimal
seesaw model known as the minimal extended seesaw that gives rise to a $3+1$
light neutrino mass matrix. We consider the presence of $A_4$ flavour symmetry
which plays a non-trivial role in generating the structure of the neutrino mass
matrix. Considering a diagonal charged lepton mass matrix and generic vacuum
alignments of $A_4$ triplet flavons, we classify the resulting mass matrices
based on their textures. Keeping aside the disallowed texture zeros based on
earlier studies of $3+1$ neutrino textures, we categorise the remaining ones
based on texture zeros, $\mu-\tau$ symmetry in the $3\times3$ block and hybrid
textures. After pointing out the origin of such $3+1$ neutrino textures to
$A_4$ vacuum alignments, we use the latest $3+1$ neutrino oscillation data and
numerically analyse the texture zeros and $\mu-\tau$ symmetric cases. We find
that a few of them are allowed from each category predicting interesting
correlations between neutrino parameters. We also find that all of these
allowed cases prefer normal hierarchical pattern of light neutrino masses over
inverted hierarchy.
