Wow you've never had Safari crash? I get that often. I also have pages freeze in mid loading, go white, then reload with a notice saying there was a problem with this page and it must be reloaded. That happens often on blog or news sites especially ones that have the DISQUS comments sections.
I had it do the freeze and reload thing on one of the major news sites when I was trying to read about the Charleston shooting. I can't remember if that was an ABC for Fox News page. This was on the loaner phone. My regular phone and my IPad 2 mini crash to desktop and do the freeze and reload thing. For a long time I thought there was something wrong with my iPhone but then my iPad was doing this, too.
I can understand your frustration with Sunking and I appreciate your patience with me. The conversations between you and Sunking are like the ones between me and my husband. My husband would totally agree with you. He thinks his 6plus is the best phone he has ever had. And for him it is. I don't think he has any plans to upgrade to the S generation. He and I use the iPhone differently and for him, his apps run smoothly and he values the device mostly for phone and email and music playback. However I do catch him having freezes and all crashes, too,and some of these are on apps we both use, like some real estate apps we use to track our local housing market. I just notice these little freezes or crashes do not seem to register with him at all. He insists his phone is great.
The camera lags include pauses that happen when I activate the camera. It's just very slow to go from whatever it was displaying previously to camera mode. There's a thread around here about the camera lags and issues. I liked all the posts that described problems I also encountered. It's a bit much to try to fit into this already long post.
I did also have early bugs and other oddities that I also did fix. I removed outdated apps that were holdovers from my IPhone 5s days that had never been updated. I trouble-shooted most of my quirkiest problems. Now I'm left with more generic ones that others here report. Well it's 12:42 here and I'm starting to get groggy and I noticed my last few sentences didn't make much sense, so I'll pick this up tomorrow.
Edit to add I just corrected the part where I say my husband uses his phone for Internet. He uses it for email. I'm the one who uses it for Internet and that's where I get much of my lagging and crashing and freezing. My husband gets Internet content via news apps and RSS feeds. When he shops he uses apps. I use Safari. He has a smoother experience on his phone because he uses it differently.
