Sony's latest smartphones and tablets can stream PlayStation 4 video games.

Owners will be able to attach the new devices to an existing PS4 controller via a special mount to play titles powered by the console's processors.

Until now this "remote play" facility had only been offered to the firm's PlayStation Vita handheld console.

Experts said the feature should help Sony's kit stand out from Android rivals at a time when competition is intensifying.

But despite the popularity of the PS4, they added, the move was likely to have only a slight impact on sales.

The Japanese company also unveiled a new smartwatch and a fitness tracker at a press conference in Berlin, ahead of the start of the Ifa tech show.

The launches come a month after Sony cut its smartphone sales forecast by 14% for this financial year, saying its original figure was too "optimistic".
