Apparently, my analog stick moves slower when I move it diagonally right and left. It moves well forward, to the right, to the left, and backwards. Is this a calibration problem? I searched on how to fix this and the PS forums said you had to go to System>System Information and then rotate it in a circular motion. I think I've already done this but it didn't work. Or maybe I didn't do it right.
Another way I found on YouTube.com was opening the PSP and then cleaning some thing next to the analog stick with a wet soft cloth and then drying it.
Can anyone help me on how to troubleshoot this? Has this happened to anyone? Does the troubleshooting I mentioned work? Thanks in advance.
