@domubpkm Using Nexus5 dev-->stable, the qt-engine update doesn't match with it... after installing the update, some apps like morph and seabass crashed after the opening screen... so I reinstalled stable version.

@lduboeuf Thanks for your new project. Well personally, in normal use, I generally completely turn off cellular data and activate it when necessary. I don't know how difficult it can be to develop, but I imagine an option that automatically turns on cellular data in case of one or more open apps or web-apps using it, and automatically turns off cellular data when apps or web-apps that used cellular data are all closed...
