Urgent issues that should ideally be fixed before final publicity step

As requested by @neslihanturan . :) I get that we can use labels, but the list itself is up for discussion, so instead of discussing it on the individual issues, we can discuss the general plans here.

My intended date to start the final publicity step (PR releases to general media, as I have already written for the Wikimedia blog and approached blogs that have written about us before) is 5 June 2017 or thereabouts. So the list needs to be attainable within a short period of time, no big suggestions please unless you think you may be able to pick the task up yourself. :)

My suggested tasks:

• Make sure that Crash when gallery image is shared with the Commons app #668 has been fixed in the recent patch
• Ask for location permissions at runtime for Nearby Places #650
• Position is not updated by nearby  #674
• Either revert to targeting API 23 or fix Crash when selecting camera #457
• Show my real-time position on Nearby map #686 (fixed, the further enhancement is not urgent)
• Make tutorial/guidelines/welcome screen accessible again at any time #671 (if possible)

I've just pushed v2.4.2 to beta, should be available in a few hours. Tested manually on API 21, API 23 and API 25, everything seems to work as intended for me. We've managed to fix everything on this list except for #674 , but we can live with that. :)

Please help test 2.4.2 if at all possible. If all goes well, I'll push that to production in a few days' time, then finally everyone can access the new features that we worked on during the hackathon.
