Ultra-strong both in software and in materials. That was the promise that Turing Robotic Industries (TRI) made with its Turing Phone, which, a good number of pre-order buyers have indeed believed. That, however, was last year. The smartphone, which boasts of a "stronger than steel" liquid metal body, has already been delayed. And now it might be delayed even more. The company has informed early buyers that it has decided to switch from Android to Jolla's Sailfish OS, a rather dumbfounding move for a device that still needs to prove it can actually reach the market.
