Background and Development
The HTC HD7 is one of the first available smart phones, which use Microsoft's newest mobile operating system Windows Phone 7. To (similar to the Apple iPhone ) to obtain a guaranteed quality, Microsoft sat down stringent (minimum) requirements for equipment manufacturers, leading in some areas to severe restrictions and increased difficulty in creating a unique characteristic. So the first HD model of the manufacturer HTC shone (with HD as an abbreviation for "High Definition ", ie high resolution is ), the HTC Touch HD, with a hitherto unprecedented high - resolution display. With Windows Phone 7 devices is WVGA (480 × 800 pixels), a fixed specification, what the real meaning behind the device names ad absurdum. Also, HTC's very popular development of the user interface, HTC Sense, can will no longer be used in the frame as under Windows Mobile and Android.
Launches and sales
The HTC HD7 is officially available in Europe since 21 October 2010. In addition to free trade, the smartphone is also offered in cooperation with various mobile phone companies.
Germany

The version that is offered by O2, has in contrast to the European standard over 16 GB instead of 8 GB of memory.
O2 announced that the HD7 was already after the first week completely sold out.
Austria
As a partner for the distribution of the HTC HD7 was the mobile phone companies and their competitors A1 " 3" win in Austria.

Technology
Chipset
The hardware base is a Snapdragon QSD8250 chipset type to the course, which was previously installed in the predecessor HTC HD2. The clocking at 1 GHz Scorpion processor core called is similar to the ARM Cortex- A8 core and is supported by 576 MB of RAM. Graphical calculations assumes the permanently installed on the board Adreno 200 chip from Qualcomm, which dominates the OpenGL ES 2.0 and Direct3D standard, among other things. The QSD8250 chipset represents the first generation of Snapdragon product line and supports multiple wireless standards including GPRS, EDGE, UMTS and HSPA. In addition, all Snapdragon chipsets include arithmetic units for decoding HDTV with a resolution of 720p and a GPS receiver.
Display
The HD7 features a 4.3 inch ( 10.9 cm) wide capacitive multi - touch screen, which dissolves with 480 × 800 pixels ( WVGA) and a color depth of 24 bit (after the HTC update only 16 bit) display able, representing approximately 16.78 million colors corresponding to (true color).
Memory
Contrary to other models, such as the Samsung Omnia 7, HTC HD7 comes in no festgelöteter NAND memory to the course, but an internal, not freely accessible SD card slot. Depending on the model is in the card slot, an 8 or 16 GB SDHC Memory Card Class 4 speed rating of the manufacturer SanDisk. The internal ROM memory with a capacity of 512 MB is here, together with the SD card, put together in a JBOD composite to a memory; within the operating system so it can not be distinguished between ROM or SD card.
Camera
The built-in camera can shoot photos at resolutions up to 5 megapixels ( 2,560 × 1,920 pixels). For light measurement is an active pixel sensor (also known as "CMOS sensor " ) for the course. Support the camera gets assisted by a dual LED flash. The camera can also shoot movies with a resolution up to 720p (1280 × 720 pixels). In addition, the user enjoys various recording programs available, including candlelight, landscape and portrait.
Radio links
Wireless the HD7 communicates via WLAN standard 802.11 b / g / n, GPRS, EDGE, UMTS, HSPA and Bluetooth 2.1. In addition, an A-GPS antenna is installed. It supports the Bluetooth profiles A2DP, AVRCP, HFP, HSP, PBAP and.
Sensors
As sensors, a G-sensor, a digital compass, a proximity sensor and an ambient light sensor are used.
Dimensions and weight
The dimensions of the smartphone be 122 × 68 × 11.2 mm (H × W × D ), the device comes to a weight of 162 grams ( with battery).
Accumulator
The lithium -ion battery has a nominal capacity of 1230 mAh.
HTC is a run-time of the battery in the GSM network of around 380 minutes of talk or 310 hours (corresponding to almost 13 days) in standby mode.
Particularity
As a special feature, the HD7 has received a so-called " Kickstand " (stator ), so that the appliance can be positioned for enjoying the medial upright on a tabletop.
In addition to the HTC HD7 was only in Europe ( currently ) not available HTC 7 Surround such a stand.
Unlike Mozart, Trophy and Co.
Models HTC 7 Trophy and HTC 7 Mozart, which were also officially introduced October 11, 2010, belong to the same Published Tung - generation of HTC for WP7 as the HTC HD7. It is still unclear whether the model HTC 7 Surround will appear in DA -CH or in Europe in general. The first generation of Windows phones with hardware keyboard only device, the HTC 7 Pro was announced by O2 Provider for January 2011 for the German market.
Since the launch devices from HTC Windows Phone 7 all have the same hardware, the differences are partly to be found only in detail.
Modifications
Internal storage expansion
Just a few days after the official release of the HTC HD7 first reports have already been published, in which described how the internal memory can be expanded by replacing the SDHC card. For this to be solved at several points below the battery compartment Torx screws to get to the card slot. However, if the card, which may have a maximum capacity of 32 GB, exchanged, so the operating system due to the separation of the JBOD network of ROM and SD card is useless and needs to be completely reset by a hard reset; So it will be deleted all personal data.
Moreover, according to several reports within the online community XDA -Developers, not all SDHC cards. During cards manufactured by SanDisk, which are also fitted as standard from HTC, appear to work flawlessly, so the tested 32 GB versions of Kingston proved to be useless.
Another problem is the fact that the now distant SD card can be due to an unknown formatting not readily off a WP7 smartphones, for example, on a computer or in a digital camera used. This helps to date only a workaround with the help of a Symbian smartphone.
On the video platform YouTube, a video was released showing the change of the SD card in detail, without a loss of warranty occurs.
Next also modification in the software are possible, the so-called custom ROM which had its origin in the XDA - Developers, but now also in German Windows Phone Forums are available.
Criticism from the community
Before the announcement of the Performance
Before the official announcement by HTC circulated a lot of speculation as to the possible performance of the HD7, which docked the bar of expectations among prospective very high. This is especially so because the "HD " model from HTC until then had always appeared to be the flagships of its own portfolio. The rumors predicted the HD7 (then " HD3 " called ) including a 4.5 inch display with a resolution of 800 × 1280 pixels and a 1.5 GHz Snapdragon chipset strong. Besides being able to play Full HD movies ( 1080p), the HD7 should have already implemented the very latest 4G LTE standard. HTC commented or confirmed rumors never These kinds.
Reactions from the community
Was correspondingly high then the number of those who were disappointed when the first effective edge data of the device have been published. Especially the fact that the device hardly of its predecessor, the HTC HD2 year, difference, caused great frustration.
Choice of Snapdragon chipsets
On incomprehension came the choice of the built Snapdragon chipsets - With the QSD8250 the first and thus oldest generation was chosen, whereas HTC einbaute in the Android segment with devices like the HTC Desire HD the second generation ( MSM8255 ). By the shrink of 65 nm to 45 nm, not only the performance was at the later chipset is increased, but also the power consumption can be reduced. In addition, the cost of production decreased, as more this can be manufactured by wafer.
Another disadvantage of using the older Snapdragon chipsets is in the installed GPU. The first generation was fitted with an Adreno 200 GPU, as done in the second generation of the much more powerful Adreno 205 their services. In a passage of the " 3DMarkMobile ES 2.0 " benchmarks the company Rightware (formerly the company Futuremark ), the Adreno 205 GPU was awarded approximately four times higher power ratings than even the previous Adreno 200
Capacity of the internal memory
As an absolute no-go set for many, however, only represents the fact that HTC is a device that is designed for the media use, only 8 GB of memory fitting out. This felt by many because of it as striking as the device has no free accessible memory card slot, so the memory can not be expanded without modification ( See also: Enlargement of the internal memory ). Some wireless service providers, such as the German operator O2, counteract the verbautem with a special version with 16 GB of memory.
