Device Not Compatible with Market

Noticed lately that I'm having problems downloading apps from the Android Market. Getting notifications saying "Your device isn't compatible with the market." Thing is, these are apps that worked find on the same SGS before.

Turns out the problem is the new LCD density I have set (via Nitrality), and not the new Surface ROM I installed. If the LCD density doesn't match, Market won't let you download the app. So, quick solution is to switch back to the original LCD density, Force stop the Market app, then Clear data. This step is done via Settings -- Applications -- Manage applications -- Market. After that, you should be able to download your favourite apps as usual. If it still doesn't work, do a clean reboot.

On a side note, you should try increasing your LCD density (if supported). Much more screen real estate.
