S3 Folio book cover

"3. Built-in magnet enable the automatic sleep/wake up function, and the magnet also keep front cover firmly closed with your tablet screen"

That part bother me. The SPen uses electromagnetic induction to communicate with the tablet and any badly placed magnet will disturb it work.
I had a case for my Tab A with Spen that has a magnetic lock and I couldn't write close to the edge of the screen where the lock was.
Someone gave a very good idea how to adapt a S2 case for the S3 but they ran into the same problem.

Can u please tell us what is your experience with this case?
Do you notice any problems with the spen close to the edge where the magnet is?
 
No problems with the magnets and the S pen, works just fine. My pen holder mod is perfect, not the neatest but 100% functional. I took an old tablet case and stripped of the fake leather and cut it into a strip, using my trusty 3m 2 sided tape I attached to the right side of the case.
