When CNET put the new Motorola Razr through a folding test, the phone's hinge starting making noises and showing issues by the 27,000th fold. That's just a fraction of the 100,000 folds the publication was planning for the device. Now, Motorola has fired back at CNET with a video of it own, showing how it tested the durability of the device's hinge. In a statement sent to Engadget, the Lenovo-owned company said SquareTrade's FoldBot "put undue stress on the hinge," since it didn't allow the "phone to open and close as intended." As such, it made CNET's test inaccurate.
