I do exactly the same as you, I read and follow what happens on Hive from my phone but I only log in from my laptop, from there I upload posts and everything.
Moreover I never connect my phone to WiFi networks, here I mean any WiFi network other than the one I have at home, I don't take my laptop with me on holidays, I use it exclusively for what I do in Hive at my home.
I might sound a bit weird, but I have my own fixations.
Now being away and not having access to my laptop I turned to my friend @missdeli to help me so I could reply, if I didn't have her with me I think I would have been embarrassed that I couldn't reply.
