My XPERIA SL too can't. I have tried so many different things with the N9's hotspot settings but my Sl just can't detect it while my laptop can. :| Why?

Make sure that you are broadcasting in the 2.4ghz range, and any channels under 11 should be used.
I am pretty sure that Nokia N9 doesn't have the 5ghz freq range (and thus anything beyond channel 13 is just not read).
Try that?

[Q] (Q) Sidesync 3.0?

Is there any chance of using sidesync 3.0 on galaxy s3 with galaxy tab s?? I know that it is an app for android 4.4, and I though that maybe flashing the phone with the new ROM ported from the LTE version or maybe with ported from galaxy note It would work. But, Unfortunely, it didnt. It worked with the PC but I have been impossible to connect it with the tablet. Any suggestions?
