Electronic devices with translating flexible displays and corresponding methods for automatic translation when operating as a controller for another electronic device

A method in an electronic device, the method comprising:

• causing, by one or more processors, a communication device to present content on a content presentation companion device in electronic communication with the communication device;
• determining, by the one or more processors, a front-facing area amount of a flexible display required for presentation of a controller user interface operable to control the content being presented on the content presentation companion device;
• and
• causing, by a translation mechanism, a blade assembly coupled to two major surfaces of a device housing and wrapping around at least one minor surface of the device housing and carrying the flexible display to slide around the device housing sufficiently to reveal the front-facing area amount of the flexible display.

An electronic device, comprising:

• a single device housing;
• a blade assembly carrying a flexible display and configured to translate around the single device housing between an extended position, a retracted position, and a peek position;
• one or more processors;
• and
• a communication device in communication with a content presentation companion device operating as a primary display for the electronic device;
• the one or more processors determining a front-facing area amount required to present a controller user interface on a front-facing portion of the flexible display and causing the blade assembly to transition to a position defined by the front-facing area amount.
