Sony has a hot hand in cameras and particularly in sensors, which earned it $2.4 billion last quarter. Its Exmor sensor is used in Apple's iPhone 6, along with other Android handsets like the OnePlus One. The new Exmor RS model will appear in April next year, perhaps in time for Sony's next flagship handset, which would give it one of the best Android smartphone camera options. However, there's nothing much wrong with the cameras in Sony's current smartphone lineup, yet its mobile division is still losing loads of money.
