1) Have only had one issue with a Sony phone in the past (I have had 4, wife has had two, my mom is still on her first one) and that was resolved through the dealer no problem (was a battery issue).
2) True, but is a very minor issue for most people. And unofficial change logs can be found online in most cases
3) Again, depends on what you want out of your phone. If you only want point and shoot, and you feel what the result the pixels or Samsungs deliver is good enough most of the time, sure, then they are better. But if you want to be able to tinker and adjust settings, then the Sony phones are a great choice.
4) Overpriced compared to what? It's a matter of opinion. I feel I get tremendous value when I buy a Sony phone. Usually there are great discount on them through carriers after a few months following release. Also I have supplied my family with free high quality Sony headphones through bundle deals.
5) Only of you plan on selling them, I have had my phones for a minimum of 3 years, and I have usually worn them out by then. Also, pretty much only iPhones hold their value well. All Chinese phones have even worse resell value and Samsung is not much better outside the super premium phones (like flips and folds)
6) That's a problem for the Sony marketing department. Has absolutely influence on the quality of the phones. Don't see how it is relevant to the discussion at all.
Feel free to call me a Sony fanboy. I have had Samsungs and HTC phones in the past, but since I bought my first Xperia phone I have stayed with the brand since.
The shutter button, SD card expansion, the near stock software, no notch or hole punch, stereo front facing speakers, good/great screens, all this is not offered by any other respectable brand.
Lately, the software updates have been coming more regularly and phones are supported for longer.
But as much as you may think I'm a fanboy, you must admit, you sound a little bit like a Sony hater ;)
