Yep that would cover much of it. For example
1) if I hit the topic title text 90% of the time it opens up the poster's profile because if one doesn't hit the title precisely there's a tendency for the finger to get a greater contact with the user name below.
2) Logs me out at every visit despite requesting other wise.
3) There is no apparent back button..
1) thats a bit sausage fingers (and something I'm guilty of regularly too), as with the dinky full qwerty keyboard, a fraction more care and precision is often well rewarded.
Also, in your phone settings there may be a screen sensitivity option where you can set it super sensitive with a sensitivity field triggering just above the actual screen to respond to a gloved hand touch, this would respond to a naked finger too and trigger the part you're hovering over just before you actually do touch onto the piece of screen you expect to open.
2) again settings - check you've enabled cookies on your phone so it knows from visit to visit what you want it to do, also remember if you delete your history or have the option to set an auto delete it is not as sophisticated as a big computer with options to just clear browsing or cached pages but still remember passwords and preferences, it will most likely just clear everything regardless and you would see it as having spontaneously forgotten what you want it to do.
3) I've yet to posess a smartphone that doesn't have an integral back button or quite comprehensive internet page history that works well inside multiple paged sites like CC. Why would people needing to provide a pared down site for a vastly less resourced and less powerful handheld devce with several other distinct uses need to clutter itself with duplications of basic smartphone functionality?
sometimes it just needs a little bit of thought around the compromises & some lowered expectation that the tiny hand sized multi function device with a relative pittance of memory & content modified from a far different platform that you are criticising is not directly comparable with a few hundred to a few thousand quids worth of PC, Mac or Linux full size device thats only function is to be a computer.
