Share Android/iOS to computer screen? [on hold]

Long story short:

My company is looking for a 1-software/hardware solution to share the screen of a Android phone / iOS phone to a computer screen (not a TV).

As a UX designer, when I need to provide feedback for our outsourced developers, I am currently either video-recording the screen or using a webcam to show the phone, and I'm sick and tired of this.

I realize you can do this on MacBook via QuickTime, but I don't have a MacBook and it's only for iOS devices. For Android I've tried Vysor and for cross-platform I've tried Reflector 3. Both are super buggy and very inconsistent, so I'm looking for a new solution.

Anyone has any ideas? :)
