[edit] Video driver issues

Soon after its release to market, reviewers and end users reported the TyTN II's graphical performance was below par. Both 2D and 3D graphics were affected, with notable symptoms being poor video playback and severely low frame-rates when running 3D applications and games.^[1][2] The hardware platform (Qualcomm 7200 chipset) suggested that the device was capable of high graphical performance,^[3] however the device is constantly outperformed by HTC products released two to three years earlier.

The community of enthusiast developers have investigated what might be causing the poor performance, and came to the conclusion that DirectDraw and Direct3D applications were running in software rendering mode only. No hardware acceleration was taking place, and the drivers required to take advantage of the ATI Imageon hardware appeared to be missing.^[4]

Many users within the community were dissatisfied by the apparent omission of a video driver that would allow hardware acceleration of graphics, particularly since the device itself included rendering hardware which was not being used. In an attempt to help drive interest and expertise from developers, the community also began raising a bounty which could be offered to any developer (or team of developers) who could solve the problem by enabling hardware acceleration with a homebrew driver.^[5] A class action lawsuit page has been established to raise awareness of the problem^[6].

There is at least one developer working on getting proper driver support working over at http://www.htcclassaction.org/. They have successfully created a driver that enables hardware acceleration under specific circumstances (everything but fullscreen). Right now the driver enables D3D and OpenGL ES. This driver does not solve any 2D drawing problems (GUI and Menus). The driver does prove that the TyTN II based devices do in fact have functioning GPU accelerated hardware, and it is enabled. It is also important to note that these drivers only work on roms based on Windows Mobile 6.1.

Some developers are now working on enabling 2D DDI support for the Polaris, which could lead to support for the Kaiser. They are using files obtained from the G810 rom(s).

Also, some users have upgraded to the driver present in the Samsung Omnia. This driver also uses software rendering, however it has been properly optimized for the ARM acrhitecture.

[edit] Versions

Besides the branding differences, there are several models of the HTC TyTN II: the KAIS100, the KAIS110, the KAIS120, and the KAIS130. The KAIS110 has no camera; the KAIS100 has a 3.1 megapixel rear-facing camera; the KAIS120 and KAIS130 have a 3.1 megapixel rear-facing camera and a 0.3 megapixel front-facing camera.

[edit] GPS Compatibility

Users of this phone have successfully installed and used other GPS map software applications (such as ALK Technologies CoPilot Live 7, DeLorme Street Atlas USA 2009, Fugawi, Garmin Mobile XT, Google Maps Mobile, iNav iGuidance, Intrisync Destinator, Microsoft Live Search Mobile, TomTom, Tracky, and VisualGPS BeeLineGPS), which are either free or cost nothing beyond the original purchase price. The map applications are compatible with the built-in GPS receiver, provided users set the appropriate COM port for the map application. The built-in GPS receiver was intended by some wireless providers to be used preferably with Telenav, which is a service that charges users monthly fees or fees based on the amount of downloaded map data. It should be noted that Telenav can only provide map data in areas where applicable cellular phone services are available and that users must have a data plan with their wireless providers.

The GPS may not activate when the phone is used indoors (or without access to clear sky) or if the person is walking very slowly (< 1 mile/hour).^{[citation needed]} External GPS antenna connection provision is provided for clear signal reception. It is important for the GPS to be activated for the various functions in the GPS software to be activated and used properly.

The elevation display from the internal GPS will be inaccurate due to it using the WGS-84 Datum which can deviate from mean sea level in the range of +85 to -107 meters.^{[citation needed]} The main reason for this is because the internal GPS uses the data it receives and references it to the Ellipsoid model of the earth which is a perfect shape. Standalone GPSes use the Geoid model of the earth which is lumpy version of an Ellipsoid. Then they apply a correction value based on the present location to supply the elevation.
