Samsung Electronics may have an unlikely reason to welcome Apple’s first foldable iPhone: The more Apple charges for it, the less shocking Samsung’s own prices will look. Ahead of Samsung’s expected unveiling of its Galaxy Z Fold 8 series in London in late July, its mobile business is walking into a hard launch. Memory and processor costs are climbing, leaks point to higher Galaxy prices, and Apple, absent from the category for years, is expected to enter in September with what could be the most expensive iPhone ever made.
