In case you need to debug mobile specific issues (as Dominik reported here: https://www.opensource-socialnetwork.org/component/view/369/fancybox)
you may install Google's Kiwi browser that includes the same developer console we know from chrome.
Of course due to the limited space the handling is a little tricky and not that comfortable compared to the PC console, but basically it's very much the same. Turning the device 90° as on screenshot 2 can help.
Due to the many requests in the past for additonal features and components we have decided to develope a premium version. Features like Hashtags, Videos, Polls, Events, Stories, Link Preview, etc included in it.
