SAMSUNG SEEMS TO HAVE LEAKED ITS OWN TRIFOLD PHONE DESIGN

Samsung's latest One UI 8 build update contains animations that show what the trifold Samsung flagship might look like. While it is labeled the ' Multifold 7' in the files, the device is speculated to be called the 'Galaxy G Fold'. The animations reveal how the device will likely fold - there are two differently sized hinges, with the left-hand display folding inward, suggesting the right-hand display is designed to sandwich over the top. Samsung is expected to reveal the latest generation of its Z Fold and Z Flip devices at its next Unpacked event on July 9.

TESLA OPTIMUS IS IN SHAMBLES AS HEAD OF PROGRAM EXITS, PRODUCTION DELAYED

Tesla's humanoid robot program is reportedly in disarray due to the departure of the senior vice-president in charge. Production has been delayed due to a new redesign. The robot has yet to prove useful in Tesla's factories. Elon Musk's goal for Tesla to produce 5,000 to 10,000 Optimus humanoid robots this year has been delayed - Tesla has informed suppliers of a two-month halt on orders. The company is likely to unveil a new generation of Optimus robots at its shareholders' meeting this year.
