Case 2. When I unfold Z Fold3 more than a certain angle or fold below a certain angle, the device is not fixed in the Flex Mode.
When the Flex Mode is enabled, the device may automatically unfold or fold below or above a certain angle due to the repulsive force of the screen.
The angle at which flex mode operates is 75⁰ ~ 115⁰, and for customer convenience and usability, it can be executed in a wider range including this angle. To activate Flex mode easily and quickly, it is recommended to open from a folded state to the desired angle, rather than folding from the opened state to the desired angle. While moving, it may be difficult to maintain Flex mode with shocks such as shaking.
Accordingly, Samsung recommends using Flex mode while the device is fixed.
