Problems with downloading apps I have recently brought a Samsung Cooper and when i was trying to download an app from the market it keeps saying insufficient memory on device. My phone has a 16GB memory card and the internal memory i big enough for the app.

Does anyone have any ideas why its saying this please.

Thanks.
One of the more obvious things to attempt is to clear the Market data/cache.

Another thing to try is to backup all data on your SD card. Next - format it from within your Android device, then copy back all the data. Corrupted files on your SD card can also cause installation failures (even if you aren't installing to an SD card), or so I've heard.
