Is this why Google’s Project Ara phones have been pushed to 2016?

Earlier this week Google announced it was pushing its Project Ara modular phone tests into 2016, but wasn’t kind enough to inform the world as to why.
Flash forward a couple of days and the culprit may have been revealed; the electropermanent magnets that were being used to hold the components together aren’t up to scratch.
In a pair of tweets posted from the Project Ara account on Wednesday, the team admitted the solution had failed the drop test and a “signature experience” was now being tested as a replacement.

What Google has in mind for the replacement remains to be seen as no further information was revealed in the tweets.
On Monday Google announced it was cancelling plans to test Project Ara in Puerto Rico before the end of 2015, adding that it was now looking for alternative test locations in the US market for next year.
