I bought this pen to replace my original S Pen which cracked and eventually got stuck in my phone. The stylus will not connect to bluetooth and does NOT work AT ALL, does nothing when I use it against the phone. The handle on the left is my real one, on the right is a fake replacement. I felt like it was schematic as soon as I opened it. There's no serial number on the back, the colors are wrong, and it's a little lighter than the original. I have already requested a refund but please take this as a warning.
