Try a different browser, try a different keyboard app.
Go in app's settings & instruct it what you want to do.
The culture of things being "crippled" is an apple trademark!
That people come here from apple complaining of something missing is pure irony. Some people have been spoiled by apple & are just lazy.
Not sure if that is directed at me, but I have tried different browsers and have 5 or 6 keyboards installed. And really, the fact that I have trouble posting here from my phone is a pretty minor problem that I don't really care to spend much energy trying to solve.
The bigger issues I have seem to be more of a difference with the underlying design of the OS. The fact that Android seems to have been designed without real multitasking in mind, and the limited multitasking we have now feels tacked on and not really integrated well from a workflow perspective. For instance, even after having my phone for 2 months with multiple ways to bring up the recent apps list, I find I only use this maybe half the time with the other half relaunching the app from the desktop or the app drawer, simply because it is more natural and easier to find (this is partly due to Samsung not including a dedicated recent apps button).
I also find that when I do bring up a recently used app that I wanted to keep running in the background, more often than not it has stopped and reloads on me. This is true of apps I just used, like if I put a video in the background to buffer while I do something else. And really true if I don't use an app for a couple of hours or more.
The copy and paste thing has already been mentioned, but this feels like another area that was just added on as an afterthought, rather than being a core feature of the OS. On a desktop for instance, a single click of a mouse will put the cursor there, a double click will highlight the word, a triple click will get the line or the paragraph. Click and drag allows you to adjust this as needed. My first mobile worked in pretty much exactly the same way and was as easy as could be. Once you had highlighted the text, a long press would bring up a context menu with copy as an option (or you could use the physical buttons to bring up the same menu).
In Android it is generally a long press to highlight one word and bring up the handles which theoretically can be used to highlight whatever you want, but IME most the time trying to do that results in spastic swings of highlighting everything except what you want. Even when it does work as designed, good luck trying to highlight more than one screen of text at a time. Once the text is highlighted a toolbar menu is supposed to pop up at the top with the option to copy, although again this just doesn't happen 100% of the time. Many times I've highlighted something and no toolbar pops up, so I have to go and switch to hacker's keyboard so that I can use a keyboard shortcut to do the same thing. When the toolbar does popup it is just icons, with no obvious icon on which one you would click to copy to the clipboard. I've also found that different apps seem to handle copy and paste in slightly different ways, making me think that it is somewhat up to the app developer to make sure copy and paste works consistently.
There are a ton of other things that feel very inconsistent. Like the change to no longer having a context menu button officially supported, which again seems to be up to app developers and manufactures on how they want to handle. I've seen a few different apps that have 3 different settings menus with different (but overlapping) settings in each, depending on how and where you access them.
And for the record I'm no iOS user. I've used it a bit at work and found it to be very frustrating, so I've never considered getting any iOS device. Although that was a couple of software versions ago, so they could have improved by now...but in general I'm not a fan of any walled garden approach.
