Two of the Windows Phone 7 devices that landed on shelves in the United States in the beginning of this week, Samsung Focus and Dell Venue Pro, reportedly come with some issues that their early adopters started to report on.

The first device is said to show problems with the microSD memory card slot, which does not offer the expandability feature that AT&T touted for the device.

According to the news, the issues emerged when users tried to install their own microSD memory cards in the newly purchased Samsung Focus.

For those who might not be familiar with the matter, we should note that, while Microsoft said previously that users won't be able to swap memory cards on their Windows Phone 7 device, AT&T touted the new Samsung Focus as offering support for expandable memory.

The main issues reported was the lost of all settings on the device after installing the microSD card and restarting the phone, though it appears that the device still reads the entire memory space.

“The SD card slot in your phone is intended to be used only by the Original Equipment Manufacturer (OEM) that built your phone and your Mobile Operator (MO). These partners can add an SD card to this slot to expand the amount of storage on your phone,” Microsoft states on its support website.

Microsoft said at one point that, in case some handsets would come with microSD memory cards installed, the device would see them as internal memory.

“Determining whether an SD card is Windows Phone 7 compliant is not a simple matter of judging its speed class. Several other factors, such as the number of random read/write operations per second, play a role in determining how well an SD card performs with Windows Phone 7 devices,” the company continues.

As for the Dell Venue Pro, it is said to have been plagued by issues with detecting private Wi-Fi networks.

According to BGR, while the handset has no problem with connecting to unprotected wireless networks, it can not reach secured Wi-Fi networks through the standard Wi-Fi utility.

Moreover, the news site suggests that the problem might be generally spread, and that other Windows Phone 7 devices would also be affected by this issue.
