Much has been made of the Samsung Focus’s microSD card slot – which users have been warned not to use with “certified” cards that haven’t been “certified.” Those who do have reported various reliability issues. However, users at xda-developers have traced the source of the problems to flawed power management software – with the result that a simple registry edit not only fixes SD card issues, but reportedly improves phone performance.
…the theory as we are working with now is that the problem is due to a power control issue in the Samsung drivers for the phone, not especially in the card itself.
No ill effects have been reported as of yet, and the battery life seems to be on par with before the switch was made. It is a simple fix, and can be reversed easily.
I ran the phone for 2 months without a card, and with these keys toggled, it is actually FASTER than it was. I don’t fully believe it, but it has been over a week and rock solid.
The actual registry edit, and related information, can be found at xda-developers here. The team are eager for testers, so any Focus users willing to help should try it out – if we can prove that it works, we may see an official fix by Microsoft in the future.
