I've upgraded the OS from Windows 7 to Windows 10. My 'one touch manager' does not start up any more. Can I install this manager?
You need to identify your phone in the list provided by Alcatel and then check if there is a PC suite available for Windows 10, because I have tried to find a version, but without success.
