Thank you so much Flohack!
I really want to keep my phone as long as possible.
And.... It works! Thanks so much advocatus, you saved my life
So the problem wasn't the sd card, but the media database. And all the media scopes find the files now, great!
In my case, I let Data on all the time especially to receive MMS (I changed my phone contract for this), but this changed nothing... And I never receive notifications. But every once in a while, I get one... Mystère!
@karstong hey congratulations!
I am installing Ubuntu Touch into the OPO!
Excited to see how it works!!!
@Lakota I do, with the calendar app and it works well. I created a Owncloud server on a computer, with calendars. For files, it should work also, but I never try.
