The issue surrounds HTC’s implementation of drivers in the device, and resulting performance problems reported by users. Essentially, HTCClassAction.org claims that HTC did not provide key drivers to enable usage of all the features of the Qualcomm MSM CPU, present in most modern HTC devices. The result has been sluggish camera viewfinders, video playback shortcomings, and a lack of 3D graphics hardware acceleration.
Initially, an HTC Americas Vice President announced that a fix was underway, but HTC headquarters issued multiple responses to the contrary. The company’s present opinion is that their devices lack the ATI/3D portion of the Qualcomm CPU. And, as such, the drivers were never written… since there is no hardware in the device to use them with.
This has raised further controversey. HTCClassAction.org argues that HTC’s (multiple) statements have been carefully worded to avoid admitting if ATI hardware exists inside their Qualcomm silicon. The site argues that HTC is simply saying they don’t use that part of the hardware, rather than it not being there.
In either case, prior to all of this, there was no distinction between Qualcomm MSM 7200 & 7500 units with, and without ATI Imageon hardware. All chips in the series were advertised with the multimedia enhancements provided by the ATI-powered additions. In fact, HTCClassAction.org cites that Qualcomm has deleted documents from their web site pointing to this fact, evidence that Qualcomm and HTC are working together to cover tracks.
The devices affected by this scandal are broad ranging, from the AT&T 8925 Tilt, to the Verizon SMT5800 and XV6800 as well as Sprint Mogul and Touch in the United States. Some users have even resorted to comparing old HTC devices against newer, Qualcomm based HTC devices. As the video shows, HTC devices years old outperform the modern HTC units in video drawing performance.
