Just yesterday, I turned off my phone for an hour and then after I turned it back on, every single thing was going slow. It took about 20 seconds to switch tabs on the HTC home plugin, and every app took a couple of minutes to open. Even menus were having a hard time opening. Also, all of my appointments and tasks were gone. I hadn't installed anything recently, or modified anything so I was stumped as to why this happened. After a while I did a clean-up with SKtools and that fixed the performance and all of my appointments and tasks decided to show up again. So I thought that was over, until it happened again. This time I hadn't turned off my phone though. Just in between me using it. So I did the clean-up again which fixed it, but does anyone know why this would happen or what would cause it? I looked at the files Sktools was cleaning up and the only thing was the google maps cache, but I hadn't even used google maps.
