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!
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.
@karstong hey congratulations!
After a first trial, I have been trying again, and this time was the good!
Thanks again all of you for your advices!!!
@domubpkm @Matyas @advocatux @Lakotaubp thanks so much!
I ordered an OPO and will receive it this week!
