The launch of the iPhone 7 could be affected by a series of earthquakes which hit southern Japan last week, killing more than 40 people.
Sony was forced to close plants in Kumamoto and Nagasaki, both of which make camera components.
The Japanese technology and entertainment giant is believed to be Apple’s chosen supplier for a new dual lens camera which is set to feature in the iPhone 7 Plus.
While Sony has reopened its Nagasaki facility, the Kumamoto plant remains closed.
Analysts forecast the closure may likely have a limited effect, but with after-shocks still hitting the southern Japanese coast the full impact of the quake is yet to be known.
Neither Apple nor Sony have commented.
Apple is looking to bolster the iPhone’s camera with a brand new dual lens system.
It’s a feature which already features on Huawei’s P9. However, Apple is believed to be reserving the system for its larger iPhone 7 Plus, in an attempt to differentiate between models in its iPhone range at a time when sales are flatlining.
The iPhone 7 and iPhone 7 Plus are expected to be revealed in September.
