Steps to reproduce:
# Open a random page (on cswiki) in mobile web browser on mobile
# Tap the page in other languages button
# Tap one of the language variants
Link leads to mobile view page.
Link opens desktop view page instead.
Note: Sometimes it behaves correctly, it opens a different language dialog, from which mobile view is openned, but only in 1 of 10 cases (or less).
Exact steps to reproduce:
# Have Android 4.4.2 Sony Xperia E1 (480 × 800 screen, portrait mode) with Maxthon 5 browser installed; have Beta features switched on on mobile (previously, I assume it is stored in cookies then)
# Open cs.wikipedia.org
# As you can see in the url, you were redirected to .m. mobile version. You are seeing a mobile version, everything is as it should be.
# Tap hamburger icon
# Tap "Random" option ("Náhodně"; it works on any page, therefore this is the best option to try)
# Tap language icon (if possible = if there is any language variant)
# Tag any language (e.g. english)
