A tech reviewer posted video claiming Apple’s first foldable, the iPhone Duo,
shows pronounced heat under the camera during video recording and other
high‑load tasks and called it among the hottest phones he has tested. The
reviewer also said he found no issue when flexing an unfolded device at Apple’s
launch, though the posted footage shows external‑screen flicker. Apple customer
service said the device is not yet on pre-sale in mainland China, described a
single‑unit online test as partial, and recommended consumers try units in
retail stores after launch. Apple added new devices may need a 3–5 day
adaptation period and said hardware‑related heating can be checked and handled
by its technical team or at service stores.
