Did you notice that in your response to me above you emphasize several times that it's a personal issue whether or not the OS works for the individual, yet in the post I replied to you made no such distinction.
That is where the exaggeration lies.
If you don't like the OS, fine. Whatever. If there are functions it can't provide, fine. Whatever. That's something that you want that the OS doesn't provide.
Well to clarify there is a reason as to why I did emphasize about one's own personal experiences, When you did mention the things that you were able to do with your own phone that was you talking about your own personal experience. Though it has been a while since I have last looked at forums here, I am quite confident that a quick scroll through them should reveal some cases where people have had troubles doing the same things that you were able to do.
This is not an thread regarding what features windows phone does not support, its more about why the OS is struggling so much to seem viable in the present smartphone market. I do believe that the real/"perceived" instability of the OS contributes a lot to the bad rap that win10 has been taking thus making it seem less viable of an OS.
Now to clarify regarding the real/"perceived" instability based on the personal experiences of several people that I know, I do believe that win10 has certain stability issues that causes concern but I also understand that win10 has been working well for some hence I would like to apologize and take back the blanket statement that I made earlier.
I would like to give one example to answer questions regarding the devices used. A friend had a lumia 640 which he updated to win10, despite not being on the fast ring, the OS experience was buggy enough for him to go for a cheap android phone instead. Do note that the lumia 640 was eligible for the update.
OS updates are pretty much the only realistic way that win10 for mobile can retain the greater part of the overall windows phone market share, Considering the fact that Microsoft were wise enough to block the older snapdragon s4 devices from getting that update, expectations were set that win10 mobile should be running smooth for the eligible phones, however as in the example I gave above, not all expectations are going to be satisfied.
Now here is the point, what is the probability that a user who has had a bad experience with win10 mobile is going to go and buy a phone that comes preinstalled with the OS just because its perceived to run better (In the case of the lumia 550 it does not really help that its also perceived to be a "weaker" phone compared to the 640 ).
It helps to think about everyone who jumped ship to WP in the first place due to bad experiences with other smartphone operating systems. It also helps to think about the word of mouth marketing that windows phones have relied on for the "golden" years of windows phone 8.
In conclusion:
Real/"Perceived" OS stability issues + Real/"Perceived" weak mobile hardware -> Poor word of mouth -> Failing OS
P.S just to clarify: I am just putting out my two cents as a former windows phone enthusiast regarding the decline of OS. If I was an android ****** then I would be off to the AndroidCentral forums. Regardless of whether my opinion is needless or not, I still reserve the right to freely share my opinions here.
