Ridiculous Lag on LG Optimus Slider
I just bought an LG Optimus slider about a week ago now, and it's been good. But recently it will lag and grind almost to a halt. I have to draw my pattern ridiculously slowly and get it to unlock, and then I have to either wait it out (takes up to 2 minutes) or go into my task killer. Sometimes it kills whatever it is causing the problem, and others I have to reboot the phone by pulling the battery. It's happening more and more and I'm to my breaking point already. A brand new phone should not be acting like this. I'm thinking it's Facebook because every time it happens, I notice it in the list of tasks running on the task killer. I just went on facebook and changed some update settings (4 hours for refresh interval etc.) and hopefully that solves it. I did a search and didn't seem to find anyone else with problems like this so I'm just wondering if anyone else has noticed this happening.
