Just checked the forum out in Chrome on my Android. No problems zooming in and out with the pinch maneuver. Every aspect of the forum resized. You might want to try Bama Samurai's suggestions.
Tried everything. All text under subcategories or log in is so tiny, impossible to read. Zooming in helps, but a few days ago, everything was larger. Any Kyocera owners out there ?. Would appreciate the help.
