I suspect that some of the Samsung Galaxy S7 cell phones are igniting because the LiPo batteries are expanding and being punctured and short-circuited by pointy soldering points or board edges. The same problem will probably not happen to Pandora and Pyra computers, because there are multiple hard and thick plastic barriers between the battery and the internal electronics. The cell phone batteries are probably just thin plastic bags that are more easily punctured. The double capacity LiPo batteries for my OQO computer all bulged out of their cases and became unusable. Perhaps cell phones should use NiMH batteries which do not seem to have this bulging problem that LiPo batteries do.
