Well, the thing is that I created an app with LocalStorage from QtQuick and last week it was working well until some update come.
I use the LocalStorage and the file storage.js that I downloaded from http://bazaar.launchpad.net/~vthompson/ubuntu-reddit-app/ubuntu-reddit-app/files
It was working very well but since last weekend it doesn't work anymore on the phone, even I reinstalled Ubuntu Touch with the new stable version (r100) and it doesn't work but on the desktop it works.
And other thing is that now I have to install the app before trying it on the phone because if I want to run it on the phone I get an error message saying
bash: cannot set the terminal process group (-1) bash: no job control in this shell
