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.

The developer of Kiwi Browser announced, that they will end the developement - as an alternative they are mention Microsoft Edge Canary
Thanks was looking for something like that!
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.
