delicate matter this, especially in ibiza.
basically I'm no fan of mobile phones in clubs neither, but IMO it's simply a sign of the times we live in. of course this convo wouldn't have come up in the nineties, but it's 2016 and mobile phones, plus all that comes with them (the built-in camera plus all the so 'social' apps like facebook, instagram, twitter, but also stuff like shazam etc) are very much part of people's lives - especially the younger generations.
then I'm saying 'delicate, especially for ibiza', because I agree, people are on holiday and on holiday just about everyone tends to get more pics, vids etc. no matter what they do, be it on a beach, in a nice restaurant, enjoying the sunset...and yeah, clubbing. add to this the ibiza virgin factor (mostly exactly that young and very mobile-affine crowd, keep in mind normally about a third of people in ibiza's clubs are on the island for the very first time) and it's just obvious that they will get pics and vids.
saying this, I'm not trying to defend them or think it's cool. I don't like it either, but I've accepted it's part of the game here in ibiza. up to a certain extent I agree that you wouldn't be on your mobile phone all the time if you were going for it. on the other hand, if you're in the zone and having a whale of a time with your group, at least in my experience, I honestly couldn't care less if people around me are chatting or taking pictures...
