Hi @mlinodasilva, If you're willing to check Ubuntu Touch OTA-15 out again, I want to know why you're receiving this permissions error. Maybe you can send me a private message on the forum when you're available and we can try to debug a little faster? Then we can post any results back to this thread.

@mlinodasilva Glad you found the answer on your own. Sadly Meizu pro5 is difficult to find hence a smaller community here. And it's hard to help when you cannot reproduce the issue.

Volume up and Volume Down work for me, but the others dont.

@mlinodasilva I have not such a problem with sound, but other users reported that already. So yes a bug. You can still install some scopes from Canonical Ubuntu store. Maybe not all, but most yes.
