Assuming this LOS issue is somehow similar to the original one back on EG30, I really think you guys are observing the randomness of it. Some people got it on the stock kernel, but most got it more commonly after flashing a custom kernel. Some got it really bad, and others like me, only experienced it a handful of times.
I believe the randomness has to do with the tower scenario for each person. If a person is in a bit of a dead zone, where a phone may battle between two towers for the best connection, that person will experience more LOS. Or if you're on the move and traveling through towers, you'll tend to see it more. That was my understanding back in October anyways. Although I don't believe the exact cause was ever nailed down. Samsung simply fixed it in the EK02 update and everyone forgot about it. I do know though that LOS was much more prevalent on kernels built from the source code they published for EG30 rather than the stock kernel that shipped with the phones.
