After the Microsoft fiasco a few year's ago, I learned to withhold System Updates for a couple of weeks. Android Forum's showed more like a month or so for some.
Personally I have a Samsung Galaxy A8 2018 Canadian model on Roger's Wireless. Before it was released in Canada, I prepped my phone by disabling the update system (risky/foolish I know & am aware) to avoid what sounded like trouble similar to Microsoft.
Yet June is rapidly approaching & while I am seeing less reported issues, have seen some that now have work arounds I can live with. Now am wondering if Pie/One UI update has been worth it or not.
*As per the headline, looking for thoughts & opinions about the Android OS 9 Pie/One UI CURRENTLY & NOT feedback on other matters*
