+xWhat on earth is a pub screen?
Certainly nothing to do with SkyDemon, by the sound of it. Perhaps your device is compromised by some sort of malware.
What I call a pub screen is an advertising for buying something or uploading an application ... Thanks for your comments, of course nothing to do with SkyDemon, perhaps I left Meteo France opened, and it created the problem. Anyway, Google is problematic in terms of these type of invasions ... I will check if this problem comes again. A malware is also a possibility, I will try to check it too. Anyway, with my Ipad I have no problem at all.
