I don't know about widespread. It was a big problem when the 4.2 OS was the only OS out. After about 22.214.171.124 or maybe a little earlier, there hasn't been nearly the same level related to phone calls. There have been a lot of resets due to problems with pictures or videos already on the sd card though.
