With its relatively low-key presence at the IFA trade show in Berlin last week, HTC seems to be content on focusing its resources on its HTC One smartphone, as this new insider information reveals. According to the source, the company will be rolling out an update that will bring Android 4.3 and the latest Sense 5 UI to its current flagship.

The HTC One is not an old device, having only been announced in February this year and has just recently made its way to US carriers. Running on a quad-core 1.7 GHz Qualcomm Snapdragon 600 with 2 GB of RAM, a 4.7-inch 1080p display and 32 GB of internal storage, the device definitely doesn’t lag behind the competition. Still, there has been talk of a new HTC One Max in the works that would stand head to head with the latest generation of smartphones.

While HTC’s silence might have disappointed those expecting a grand new smartphone, owners of the company’s current phones would probably gladly welcome this new information. This rumored Android 4.3 update will roll out in two waves, with US handsets receiving the update first before it starts rolling out to international markets.

The source doesn’t give out a clue as to when this update will commence, but it seems that not all recent HTC smartphones will be blessed to receive the updated. While the HTC Butterfly S will be getting update, phones such as the HTC One S and its variants, as well as the HTC EVO LTE will not.
