Prompted by the controversy over whether a Samsung Focus (and, thus, any Windows Phone, presumably) can utilize additional storage via microSD expansion, I decided to give it a shot.
You may recall that Microsoft said they would not support this upgrade, and that its own testing, verified by others, suggests that this upgrade is fraught with reliability and performance issues. But AT&T has said explicitly that the upgrade is supported and will work just fine. I guess it comes down to whom you trust.
The rules here are simple. If my upgrade works, this proves nothing because others may do the same thing and fail. If my upgrade fails, Microsoft is right, and AT&T is wrong. There’s nothing like a definitive answer. :)
I purchased a 16 GB microSD card that Patriot markets specifically for the Samsung Focus. Well, at least on Amazon. When you actually get the package, you can see that it’s a generic class 4 microSDHC.
Before wiping out the phone via the Reset function, I made sure all my phone pictures were downloaded to the PC. In Windows, I told the Zune PC software to “forget” the Focus, and then removed it from my allotments for both Zune Pass and the Windows Phone Marketplace.
Then, I removed the phone from the PC and shut it down.
Opening the back battery cover on the Focus, you can see the slot for the microSD card. Plugging it in is a fairly straightforward affair.
When you turn on the phone, it boots up normally and doesn’t “see” the microSD card. The About screen still reports the old storage amount.
So I did the reset. After a few “are you sure”-type screens, the phone reboots and comes up in its virgin state. I logged on with my Windows Live ID and headed back to the About screen. Voila. It now shows the additional storage, for a total of 24 GB (8 GB internal plus the 16 GB microSD). Well, it’s 22.09 GB thanks to the wonders of PC/electronic device math, or 20.94 GB of available storage, thanks to the requirements of the OS.
As I write this, I’m re-downloading apps and games over the air, and I will sync it back to the same PC and see how things go. As you hopefully understand, it will take a while before I can be sure all is well. But I’ll report back if I have any issues, and over time, if I do not.
Wish me luck. :)
