Off-hand the only things I can see in the above OS/phone/browser are:
1) when the smiley face on comment forms next to comment subject fields is clicked the dropdown icons/emoji table stretches the page out, so yeah, horizontal scrolling's needed, which also obscures the username/password fields but that can be reigned in
2) most of your entry and comment titles wrap to two or three lines. There's enough space to stretch them out a bit more - if desired
2a) more minorly, entry and comment titles aren't clearing the entry/comment usericons. That might be intended, to save space, so I'm only mentioning it in case it's not (they don't bump though, they just don't clear)
3) the expander for cuts isn't aligning at all
Also, I took my screencaps in portrait, not landscape mode as I've got the phone locked against landscape but I can change that if you want landscape, too.
I also have Chrome and Samsung browsers on my phone, if you want some variety.
