HTC One X+ updates top Android line The phone will launch with the latest Google operating system, Jelly Bean, and HTC also announced that the new software will be available as a free upgrade for existing One X and One S devices. HTC describes the X+ as a "refreshed" version of the original X, which launched in April. The new model features 64GB of storage, a 1.7 GHz quad-core processor and a 2100 mAh battery that HTC claims will offer up to 50 per cent or six hours more talk time. It will also improve the company's Sense interface with a new self-portrait mode for the front-facing camera and a sightseeing mode that claims to improve colours. The original One X marked a return to form for HTC and sold well where it was available. Stocks were troubled by American law suits, however, and the device initially struggled to gain momentum. The business, which recently also launched its Windows Phone 8 devices, has struggled to compete with an increasingly dominant Samsung and Apple, but its phones have continued to garner excellent reviews. In the new model, HTC continues to emphasise Beats Audio, improving music performance, and it will improve access to videos across a range of devices via its Watch services. An online service will also allow users to configure their homescreens and widgets and then download them to a device. The new device and the software upgrade for existing handsets will ship later this month. It retains the 4.7" screen and slim 8.9mm form factor. In April, the One X was also one of the first Android phones to include a function that allowed users to reject calls but also reply with a preset text message and set a reminder in their own calendar to call the original person back. Apple announced a similar feature last month in the iPhone 5.
