This question already has an answer here:
I understand the mobile version is deliberately missing some features, so I'm not surprised to not see a "Review" link in the top bar.
However I can access my profile, bring up the "Activity" view, select any "Suggested Edit" I have made, rejected or approved, and then I'm magically taken to the full-featured version of the site; from there I can access all the review queues I normally have access to, and start reviewing, say, suggested edits (here, my last 5 reviews were made from my mobile!).
If we're not supposed to be reviewing using the mobile version, then why is it possible to do it through the "back door"?
Besides, I find the format of the review queues is fairly suitable for mobile (given minor layout adjustments), I think it should eventually be implemented.
