My old phone (Samsung Galaxy with a early version of Android OS) worked excellent with the old version of Xweb. But I had lots of issues similar to yours after the new version of Xweb came along. As things turned out I needed to replace that old phone for other reasons. The new phone (with the latest version of Android OS) works with the new version of Xweb perfectly. So I assume there are some incompatibilities with the new forum structure and certain Android operating systems.
That being said, at times some images get a little cut off the bottom on my computer, unless I fully open it (the little box with a angled arrow). So there could also be resolution conflicts like @MarkF said.
Since you no longer get any sort of owner's operating manual with electronic devices anymore it's difficult to find answers for stuff like this. Sometimes I find a little info online but it usually isn't directly related to my situation and is seldom very specific, so it doesn't help much.
When I started looking for a replacement phone I thought about getting a iPhone this time (I've always had Android phones). But three things stopped me; for the most part I still just use the phone as a phone so all the extra features of a iPhone would be wasted, I'm comfortable with how Androids work (know nothing about iPhones), and the iPhones were way too expensive for me (the new Android was about 20% the cost of a iPhone). But I admit they are impressive.
My last android was CAT, no iphones before that.
I was so devastated of it's errors, couldn't pick up the call at last time before I smashed it into the concrete floor. The saddest is that it didn't even get a scratch that made more devastated hahahahahha
bought 5s about 5 years ago, it still works, just lazy to change a display and battery
6s last year, didn't want to change a broken display; and exchanged kettle of tomato soup for 5 SE, I just like design of 5th, and don't care much of the operating system. If internet disappears on earth I still have my 2nd favorite design phone - nokia 3310
