  We report on a numerical reinvestigation of the Aoki phase in full lattice
QCD with two flavors of unimproved Wilson fermions. For zero temperature the
Aoki phase can be confirmed at inverse coupling $\beta=4.0$ and $\beta=4.3$,
but not at $\beta=4.6$ and $\beta=5.0$. At non-zero temperature the Aoki phase
was found to exist also at $\beta=4.6$.
