[unsignedint]

Somewhat related to screen size, but the biggest problem (at least for my use case) is multitasking.

For instance, sometimes I translate documents, which requires an editor (displaying original / result texts), a dictionary, a browser (for reference, etc.) and maybe other texts and images open at the same time -- and switching between those, let alone seeing them side by side is nearly impossible. (And this is probably specific to Android's limitation, but when I switch back and force between apps, there is no guarantee I will be getting back to where I was -- I might have to open the app again, open the document, which makes it a lot more disruptive than working on PC for most simple translation projects.)

Maybe this will improve, but simple copy and paste across different apps on the phone is frustrating enough that I wouldn't personally do anything beyond simple quick tasks on my phone.

This is just an FYI. The Android issue you pointed out is actually an app issue. In Android, there is a mechanism for saving the state of your app, so that you can get back to the same place when you switch away from and then back to the app. Some apps don't implement that (as a good practice), and it is quite annoying when you run into it. I've seen that issue often, even in apps built by large well-known companies.

I know what you mean regarding copy/paste. Maybe it is due to the touch-based interface, but it is annoying regardless of whether it is on iOS or Android.
