Samsung smartphone explodes in man's pocket

This is the terrifying moment a man's smartphone explodes in his front shirt pocket.

Hotel supervisor Yulianto, 47, was waiting in the lobby of the building when he suddenly felt the device heat up.

He reached up to the phone in his front pocket but moments later it erupts in a fireball.

CCTV captured the moment the mobile phone exploded and burst into flames at the Hotel Ciputra in Semarang, Indonesia, on September 30.

Yulianto falls to the ground as an onlooker rushes to help him. He then rips off his shirt while it is engulfed in flames.

The hotel worker said he had never had problems with his phone before but suddenly felt it heat up.

He said: ''There was a strong sensation of heat and I felt something start to shake.

''Before I knew what was happening there was fire and I panicked. I took off my shirt as quickly as I could.''

Police said that Yulianto was rushed to hospital where he was treated for minor burns on his chest. The injuries were limited by Yulianto quickly taking off his top.

He is said to have been using the Wifi, Bluetooth and GPS simultaneously causing the phone to overheat.
