Earlier this week we touched on the problems and lack of information plaguing new Windows Phone 7 owners when it comes to compatible microSD expansion memory cards. To this day, there have been conflicting reports on what works and what doesn’t work. Class ratings do not seem to be a guarantee that a card will work in your Windows Phone 7 device. Right now, it’s all over the map. Some work, some don’t work. In our experience with a 32GB SanDisk class 2 microSD card, the phone would completely lose data. Some times it would reset with all of my media in tact. Other times it would reset with missing tiles where an email tile had been previously set up. In a word, the phone was unreliable. We had heard, although it’s not mentioned in the Samsung Focus Quickstart Guide, that a class 4 card is required. That doesn’t explain all of the folks having trouble with Class 6 cards.
At the end of the day, the Samsung Focus is a consumer phone, one that offers microSD expansion as one it’s main features. Page one of the manual offers directions on how to insert a memory card. Most consumers will find themselves picking up a SanDisk card and not think twice about find a class/brand that’s compatible. On Android, there is no need to find a compatible card. Sure, better cards will result in better performance.
Now to part deux. It’s not clear if there is a way to reformat these cards that don’t work in your Windows Phone 7 device. I’ve seen one mention of reformatting working in Windows Phone 6.5, but that’s unconfirmed. Right now, if you attempt to use a microSD card in your Windows Phone 7 device and it doesn’t work, you’re out of luck. You can return it with data of some sort, but it’s not as if you can easily use it in one of your other devices, as mentioned by Joshua Topolosky from Engadget.
If the editor of the leading technology blog cannot figure out a solution, how is Joe Consumer. A solution from Samsung or Microsoft is needed and fast.
