A few days ago, a mysterious HTC device cropped up online in an image, and rumor was it was a 5-inch successor of the One X, named the One X+ specs of which have already been rumored in the past. Now, in a new piece of info from Twitter user Football4PDA, more specs have been revealed of the device.

As was previously rumored, the One X+ will apparently sport an nVida AP37 1.6GHZ quad-core processor, 1GB of RAM, 32GB of internal storage, and will run Android 4.1 Jelly Bean with HTC Sense 4.5 on top. The battery will remain the same as the One X, aka 1800 mAh. The One X will also be be 134 x 70 x 9.3 mm in size and weigh 129g according to Football4PDA.

The size of the One X+ seems to be quite similar to the One X, so unless they fit a larger 5″ display on it without increasing the size of the device, the display might remain at the same 4.7″ of the One X (which isn’t bad by any means). Of course, a rumor on Twitter with no proof other than the tipster’s own words shouldn’t be considered solid information, but all these rumors suggest that a One X+ is coming soon with a faster Tegra 3 processor, and probably a larger screen as well.

HTC is holding an event on September 19th, where everything shall be clear. With competition amping up from other manufacturers (particularly Samsung), HTC would need to show something really nice to improve their market share and falling profits.
