Notice: With the Android ecosystem,
some available Play Store applications
only operate correctly with phones
that have a specific screen resolution.
Please be advised that some of the
applications on Play Store may not be
available for your phone due an LCD
resolution requirement that does not
match your phone. In addition, please
be aware that 3rd party applications
with programming defects may cause
abnormal behavior of your phone.
