I have not heard of this happening before.
Are you running firmware 1.80.1?
My suggestions in order of what to try:
- upgrade the camera to the newest firmware
- upgrade the mobile app to the newest version
- restart the Z1 by holding down the power button for more than 3 seconds
- turn off battery saver, bluetooth, data on your mobile phone
- uninstall the mobile app. Reboot your phone. Reinstall the mobile app.
If everything above fails, you can try and delete all the settings of your camera.
This is more tricky. Your options
- if you have Android, you can use this internal testing app. more info
- If you can use the command line, then this tester has much more features. Information on how to reset the settings. how to install the command line app.
