Update: Apparently that whole thing about the phone failing the drop test was a joke, according to Project Ara's later Twitter post, but apparently they are still using a new way to connect the modules together and ditching their electropermanent magnet idea.
Original story: Google confirmed earlier this week that the first market pilot for its Project Ara modular smartphone would be pushed back from late 2015 to sometime in 2016. Now a new message on the project's official Twitter account may have revealed that the reason for the delay was due in part to those smartphones failing drop tests.
The messages stated:
Ironically, Android Central's Russell Holly predicted that the electropermanent magnet idea for modular smartphones wouldn't work nearly two years ago. So far, there are no details on what Google plans to replace this method with in future Project Ara phones.
