Hi. I'm getting quite irritated with my Galaxy W being sluggish sometimes. For example, when pressing the home key from an application, it takes a long time for the home screen and icons/widgets to appear. Still running stock ROM, here are the storage stats: system storage: 415MB/1.07GB usb storage: 490MB/1.70GB sd card: 4.38GB/7.20GB I've already transferred most apps to SD card, and I don't think my device memory is that full. Maybe you can suggest something to improve my device's performance. Thanks in advance!
