A YouTube user going by "GadgetReviews" posted a 12-minute video taking us on a walkthrough of the HTC One M8 on Sunday, confirming pretty much everything we've already known before it's set to be unveiled in late-March.
The video has been taken down, presumably because it revealed sensitive information, like the IMEI number (a no-no), of where the leak might have originated from. Update: it's been reuploaded by others.
The video gives a full, complete overview of the device, including the dual-cameras, on-screen capacitive touchscreen, microSD slot, Sense 6.0 with redesigned BlinkFeed software, and a lengthier build.
Not shown in the video are reported specifications. The HTC M8 is believed to feature a 2.3GHz quad-core Snapdragon 800 processor with 2GB of RAM, 16GB of storage, and a bigger 2900mAh battery.
This should hold you over until 25 March, where things will become official. Check out the gallery for all the glory.
