OP, perhaps you ordered the CEP02 from gearbest? It’s a cheap passive stylus simulating your finger, it isn’t very useful.
The “official” active stylus is available on geekbuying for about 35$, or you can get the Hi12 stylus which should be exactly the same for 22$.
As I remember possible the Stylus for the Hi12 Dual Boot. But from built, its the same one. Don’t you like it? Got my Stylus yesterday from Geekbuying.
Could you post your impressions? And how quick did Geekbuying send it to you? I’ve been waiting for a week since I ordered..
