This you see a LOT around updates, where people say “it’s a bug!” even before they’ve tried factory reset.
To be classified as a genuine Bug:
- Will be there AFTER factory reset.
- Can be replicated on more than one device. After a factory reset.
To have some issues on a phone after a big update is “normal”, as it depends on the phone in question.
If you do a factory reset and the problem is gone. Sorry, but that wasn’t a bug. And you should read this.
And, if you’re curious where the term “bug” comes from. Then THIS will be interesting.
