Started happening a few months ago. Both my wife's (stock 2.3.4) and mine (rooted CM7) both freeze after calls and randomly freeze up and become unresponsive periodically. I've sbf'd my phone to fix it but it eventually occurs. Anyone else experience this? Because both our phones started doing this at the same time it almost seems like a self destruction of sorts. Why do both phones do this? Will start logging the phone activity to see if anyone has an answer after I upload it.
