The goal of Step 4a is all edges oriented. The algs to orient are
only a few turns long, but several require you to repeat or use more
than one. After a short while of practice, you can generally do them
without thinking. The longest is when all 6 edges are incorrect. You
have to perform three algs. Still, with practice, you can see the
initial case and instantly know which steps to go through.
Corners stay oriented when you finish Step 3. They don't change at
all afterward. I think you meant edges. Your problem is probably
that you're not orienting the DF and DB edges, or perhaps UL and UR.
Try this instead: Sometime before you begin your step 4 orientation,
try to get the U or D center on top. Then, orient accordingly. All
edges with your U or D color will be easy to tell if they are oriented
or not. In the end, this is not quite as fast, and you aren't able to
optimize as well, but this is a much easier orientation definition to
start with. If an edge has the U or D color facing up (or down on the
D side) it's oriented. If the U or D color is facing the side, it's
incorrect. Try that for a while. Good luck!
