This is interesting because prior to this, a benchmark revealed that the HTC One A9 will come with Android 5.1.1 Lollipop. The fact that the rumors are now claiming that it will run on Android 6.0 Marshmallow suggests that it will probably be launched towards the later part of the year, or that the OS could be pegged for a release soon.
There have been some rumors to suggest that on the 29th of September, HTC will announce their new handset alongside a potential round smartwatch, but to date there has not been a formal announcement save for a teaser image, so it is unclear as to what kind of products we might expect.
Other rumored specs of the HTC One A9 includes a MediaTek Helio X20 chipset that will feature 10-cores. It is also rumored to come with 4GB of RAM and LTE Cat 6 connectivity. In any case do check back with us in the coming weeks where hopefully we will have the official details for you guys.
