Please don't take offense, but your status as the OP has no bearing on the responses that the thread will accumulate. So long as everyone posts in a respectful manner, they're free to respond in any way they choose to.
If you think of any random conversation you might have on this topic in person, "yeah, I went back to my old phone because the new one was having BT issues" might get a reply such as, "oh, weird I have the same phone and haven't had issues". Whether or not you're seeking that response, it's a perfectly natural response and it's also totally normal for people to try to help when they discover a peer has a problem.
Sorry to hear you were having issues, but if you're not looking for assistance or for people to discuss the issues, then I'm unclear on why this thread exists. I also did read the part where you were looking for details of other potential dealbreaker issues for people, but took that as a normal click-bait-esque "sound off in the comments below" sort of thing, not the actual topic you wanted to discuss. If that's the actual topic, would you like your topic title changed to reflect that?
