When transferring my Threema backup from my Fairphone 2 to the new Model 3 via USBI have the problem that the file > 2.3GB cannot be transferred to the phone. The transmission stops immediately with error ‘Das Gerät reagiert nicht mehr oder die Verbindung wurde getrennt’ (free translation: ‘The device is not responding anymore or the connection has been disconnected’). Smaller files work without problems. I thought the limit of the filesystem is 4GB?
