You are right. I don’t experience 90% of what others do because I restore my phone on a yearly basis, if not more frequently. It takes me all of 30 minutes at most to reset it up to my liking. The longest part is my watch and recalibrating it. A lot of what people experience is because of corruption that any software will have. I can’t tell you how many times a year I had to restore my windows XP machine. At least every quarter. And that was a giant pain compared to a phone.
You choosing to not restore is on you. Therefore you have to live with the bugs that you see and can’t complain about them. It’s like those that complain about politics but don’t vote. If you have an option to fix it and don’t exercise it, you can complain. Sorry - I know it’s harsh but it’s true.
I don't experience most of the bugs reported here, either... and I have always done an OTA upgrade in place... for as far back as I can remember... as with most things around here, YMMV.
