This sounds like we should expect performance regressions, which seems logical, seeing that memory timings are tweaked to resolve the issue if I understand correctly. Not that I’ll notice much for the use I make of the phone, unless it’s really significant. But I’m still curious to hear if those who installed the update noticed any of that.
My phone is randomly rebooting once a day also, but it is a bit older than the August 2017 date usually cited for this particular bug: It was replaced on warranty in May 2017. Do we know if there were already affected phones in the circuit at that time, just maybe not in retail?
