WHAT IS THE ASUS ZENFLASH?
It is simply an external flash module made specifically for the ASUS ZenFone 2. And when we say specifically, we mean it; it doesn’t work with any other mobile device, not even another ASUS smartphone like the ZenFone Selfie. It even says so on the box, ‘For ZenFone 2 only’.
Physically, there is nothing to indicate that it was made with such a specific purpose. It comes inside a rubber case with a ring on a corner, probably for easy carrying. On the module itself, there is a strip of Velcro on the back, with the hook side of the pair you can stick on the ZenFone 2 via the adhesive back.
