It looks like the phone got a bit wet and the owner thought that he could dry it out by sticking it in the microwave. What could possibly go wrong?
According to Reuters, the investigation by independent Fire Investigations had cleared the Samsung device and said it was not responsible for the cause of the fire, and that an "external energy source was responsible for generating the heat".
The Dublin user posted comments and photos on a website in June, saying his Galaxy phone had "exploded" while mounted on his car dashboard.
While he was driving, "suddenly a white flame, sparks and a bang came out of the phone," he said.
Samsung contacted FI-UK, an independent British provider of consultancy services into fires and explosions, to determine the cause of the fire.
It provided FI-UK with several Galaxy S III phones, including the burnt smart phone, for a series of tests.
The investigators found that the only way it was possible to produce damage similarly to the damage recorded within the owner's damaged device was to place the devices or component parts with a domestic microwave.
The investigation also showed that the unnamed user's latest comments posted on a web site, saying the phone had been recovered from water and the damage "occurred due to a large amount of external energy" which apparently was used to dry out the device.
