It may just be for the Korean units, but I have to say that this is not surprising, but also kinda irritating.
It kinda feels to me that LG didn't bother to find the real cause on why the G4 kept bootlooping and instead just placed a stop-gap solution of just fixing affected devices until they're out of warranty. That might not be so, but I can understand how many G4 owners now feel.
Maybe we'll get more word in the future, but this is definitely very bad news for those of us who are looking at LG handsets but are also concerned about updates.
