HTC posted a new image on its official Weibo account teasing a new device. As we can see from the image above 820 is a prominent figure suggesting that the Taiwanese company will be debuting the rumored Desire 820 sometime soon. It's possible that with IFA in a few short weeks, we could see it then.
At this point, not much is known about the device. What the device has for hardware is anyone's guess. Of course as we edge closer to IFA we may get a bit more of a glimpse of the rumored device. We'll keep you updated as this develops.
