How do I make my phone crash or lag?
That effectively is my answer..not once did I have my Epic 4g lag or crash unless I was testing beta software that used root functionality..most of the time as stated it just FCs the program in question...I went months with no resets, lag or freezing...
I even played 3d games and do other things at same time with no lag..
Not to mention if I feel like restarting my phone..it reboots in 15-20 seconds..yup that fast!
