I recently installed the Kit Kat update and everything is great, except when I tap the screen it makes this crackling or popping sound. Once it makes this sound once, it stops for awhile, however, it comes back if I leave the screen idle. So as long as I'm using it there's no crackling, but it immediately makes the sound after it's touched following a period of inactivity. It's really getting on my nerves and I wanted to know if anyone has had this problem and if anyone knows how to fix it.
My system version is 183.46.10, build version KDA20.62-10.1 on Kernel 3.4.42-g5170b6b running on AT&T with the gsm hack.
