I recently bought a ZTE Cymbal 2 (Z2335L). I've tried various versions of Virresh's mouse cursor app, but am unable to click anything. I'm not sure if this is helpful, but when I installed KCO mouse, that I downloaded from here, I clicked on the Detect button and noticed that no key is detected when I click the middle d-pad button. Every other key is detected except that one.

I read this comment by @Techgen where thee was a modification on the cursor app to get it working with Sonim Xp3 plus. I was wondering if something like this could be done for the ZTE Cymbal 2 as well.

Let me know if I can help in any way.

Thank you.
