Berliner Sparkasse Onlinebanking FAQ :
Why do I get the message ‘mobile device, can’t perform smsTAN money transfer’ when using my Desktop computer.
A possible cause is the display resolution. Your computer is being detected as a mobile device by our online banking system. smsTAN is not working from a mobile device.
Solution: Change the display resolution
So 1920x1080 does work, but 1080x1920 doesn’t.
