Days after the Apple’s new flagship device went on sale, the company has started investigating reports of its iPhone 8 Plus bursting open.

The reports from Taiwanese media and some pictures on social media have circulating from past couple days showing an £800 iPhone 8 Plus handset that appeared to have split.

According to the owner, the device’s casing cracked open as it was charging, and the phone had reportedly been in use for only five days and was being charged with device’s own official cable and power adapter.

Other than that, another customer from Japan also claimed that their iPhone 8 Plus had been delivered to them with the detached screen.

It is understood Apple believes the problem was caused by the battery swelling and does not pose a safety concern. The company also confirmed it was looking into reports.

iPhone 8 and the 8 Plus started shipping to the first customers two weeks ago ahead of its official 22 September release date.
