TL;DR If your computer is connected to Ethernet as well as Wifi, take the Ethernet cable out !

My Macbook just would not transfer files to my iPad or iPhone. Sometimes it would 'see' the device, but transfer would time-out and fail.

I had tried all the suggested solutions:

  • Flight mode is Off
  • Both devices on the same Wifi network with Bluetooth enabled
  • OS up-to-date
  • Discovery mode is set to Everyone or 'Contacts only' if the devices have each other as contacts
  • Turned Wifi and Bluetooth off and on
  • Open Airdrop folder on the Macbook
  • Reset Nework settings
  • Hard reset.

In other words: 'The Works', matter what I tried, nothing worked.
At my desk I tend to also connect the Ethernet cable even if Wifi is active and guess what:

Unplugging the Ethernet suddenly made Airdrop work!

Hope this helps someone

Funny, once in a while, when you listen to music you'll think : He, we played that song! 
Maybe it is the time of year, but you start to wonder:  "what else did we play?" and before you know it, you'll want to start playing again ..

Some weird pshychology going on here:

Since my phone contract was up for renewal, I was offered a 'free' update for a phone of choice (within limits).
I owned an iOS phone already (iPhone 5, still going strong ..).
But besides that I was interested in starting development for Android as well, so I figured:
I could choose an Android device this time and use it for development only, leave my old SIM in the iPhone.
And so I did.

So now I've started testing on my LG G4 (on Android Lollipop).

So what is with the weird psychology  going on?: 
Well, on day one I'd think: this phone (LG-G4) is rediculously large ... 
On day two I'd think: this phone (LG-G4) is rediculously large ...
On day three I'd think: My iPhone 5 shrank, it feels rediculously small ...

Isn't that weird? the mind boggles  ...

PS, I still use the iPhone 5 as my phone, it is far more practical,
but I would not have thought I'd get used to it's display size as fast ... If only it would fit my pockets ...

If your cardboard viewer (or clone) does not exactly fit your phone, you can get some weird artifacts when viewing demo's/ apps (extra distortion / invisible screen areas etc..). 

Cardboard apps assume a certain geometry:

  • vertical alignment of screen and viewer
  • horizontal alignment of screen and viewer
  • eye distance to lens 
  • lens distance to screen surface

Since the last two are mainly determined by the geometry of the viewer itself (Ok, lens distance to surface also depends on the thickness of your phone...), these are usually OK, but the frist two depend on the dimensions (width/height) of the phone. 

I purchached a BroFish cardboard viewer (B.T.W: great value for money!) and it was obvious that my iPhone5 was a little too small, it sank too low and could wiggle from side to side.
Not wanting to use the small rubber band to hold it in place, I did the following: 

It came in a carboard box, how appropriate :-)

From the packaging box I cut out 2 identical frames.
Each with with dimensions of about a 1 cm (1/4 inch) around the perimeter of my Phone.
This was in my case an iPhone 5 which measures around 6.0 cm by 12.35 cm.
I made cutouts for the volume / power buttons, so they would not touch the frame when the phone was insterted. 
I glued the frames on top of each other with double sided tape.
The resulting frame I positioned on the cardbard back-plane so that it would be centered both horizontally and vertically in the field of view of the stereo lenses of the viewer.
Once satisfied with the position, I pressed it into place with some double-sided tape.

Since I wanted to be able to test my App connected through USB, I also made a cut-out for the Lightning connector, so I can test connected.

So there you go!
