As many of you know, our OneX is equipped with the Wi-Fi Direct function, but is totally unusable because it lacks the application to use it, so after testing various options I found the one that best fulfills its task: it is an apk extracted from an asus tablet.
Once installed you will find the wifi direct under sharing options in the various programs.
Tested with Cm10.1 and stock rom.
Now you can share your files with other wifidirect capable devices....
I can't be sure, but it should works with other HTC devices too (One, OneS, etc. ....)
