HTC has just confirmed the existence of its long-rumoured 5" Android model, in the big block format of the HTC Butterfly J. It leaps straight to the top of the pixel density charts with a huge 440ppi count.

That impressive number comes thanks to HTC sticking a full HD 1920x1080 resolution Super LCD 3 display into its new 5" shell, which will be managed by Qualcomm's quad-core 1.5GHz Snapdragon S4 Pro. Android 4.1 and HTC's latest Sense user interface take care of the smartphone business, while Android nuts will be happy to learn there's 2GB of RAM and SD card support in here too.

It's a shame the Butterfly J has only appeared on HTC Japan's site at the moment, as this is a dead-cert upgrade should it every hit the UK. [HTC Japan via TNW -- Thanks Darrell]
