HTC unveils One X+ smartphone on Android 4.1 Jelly Bean

Firm hints at October release date for latest high-end device

HTC has unveiled yet another new smartphone, the HTC One X+, which will arrive running Android 4.1 Jelly Bean as it seeks to claw back market share in the face of tough competition from Samsung.

The handset is essentially an upgraded version of the HTC One X smartphone with a faster 1.7GHz quad-core Nvidia Tegra 3 processor and 64GB of internal storage.

It also feature a 2,100mAh battery and the latest version of Google's mobile operating system, Android 4.1 Jelly Bean.

According to HTC, the One X+ is 67 percent faster than its predecessor and boasts an additional six hours of talk time.

"We are taking the HTC One X to a new level with the introduction of the new HTC One X+," said HTC chief executive Peter Chou.

"Our customers will have super-fast browsing, an even better camera and more immersive entertainment with Beats Audio."

The HTC One X+ also features a 4.7in S-LCD2 screen, HTC Sense UI 4+, an 8MP rear-facing camera, a 1.6MP front-facing camera and support for LTE connectivity.

It's unclear whether the handset will support EE's 4G network like its HTC One XL sibling.

The HTC One X+ will be available in Europe later on this month, although HTC has not announced any release dates or pricing yet.

The new device comes after HTC unveiled two high-end Windows Phone 8 devices in September, including the WP8 X which it touted as the flagship device for the new operating system.
