I am a heavy user of the mobile site on a Motorola Droid Bionic running Android 4.1.2. I generally use Chrome as the browser. Basically works great with a few quibbles (can't see a poster's post count, for example, or signature).
The one that bugs me the most has to do with threads that have lots of images in them, such as "Picture of the Day" or "What Are You Drinking Now?". On a "normal" thread, the app accurately remembers where you left off reading that post and auto-scrolls you to that position. However, on a picture-heavy thread, this feature stops working correctly. Instead it auto-scrolls to some mysterious place that is generally way "earlier" in the thread than where I'm supposed to be. That forces me to manually scroll down to my last stopping place. Because threads with lots of pictures take up huge vertical space on a little phone, that means I have to do a TON of scrolling. It's a pain. Ideas?
