According to a new report by the The Elec, Samsung has started testing the new teardrop hinge for its upcoming Galaxy Z Fold5 smartphone, expected to launch in the second half of this year, presumably August, as usual.
The teardrop hinge is a commonly used design that lets the axis roll on itself inside the hinge and has several advantages. It reduces the gap between the two halves of the phone as well as minimize the wrinkles on the screen.
During this year’s CES 2023, Samsung demonstrated a new hinge design that’s 14mm thin as opposed to the current implementation measuring 15.8mm in thickness.
The news doesn’t come as a big surprise as several reports in the past have come forward stating that Samsung is working on an improved droplet hinge design.
Anyway, Samsung’s internal testing may take a while because a single prototype takes about five days to test. The benchmark is 200,000 folds, after which the hinge must retain at least 85% of its initial tightness and strength.
