Hello! Just got the Xperia Z1 and still fiddling along. Read all the threads in here but cannot find anything similar so I started this thread. If it dies, I will remove it. Tip #001 Light Flow It "wakes" up the screen for calendar reminders, some battery status, emails and SMS. Paid version allows notifications from apps like Viber, etc Tip #002 Power+VolumeUp button to soft reset (restart/reboot) the phone. Thanks in advance!
