Hey jbaach,
I know you've already tested the browsers on both devices, but would you mind testing the files attached below? It is Android developer's guide from Google, which is just a bunch of HTML and CSS files packaged in a folder. I'm really interested in seeing if both devices could interpret file structure inside the folder and render these offline HMTL pages correctly. Could you click on "index.html", then the "Dev Guide" tab and then just click/scroll around a bit? (to keep the file size managable I've removed the content for other tabs)
Thank you so much; I was kinda annoyed by the delayed availability of PB912, but now after watching your video reviews I'm going to get M92 instead
