Electronic devices with translating flexible displays and corresponding methods for presenting notifications without resizing presented application portals

An electronic device, comprising:

• a device housing;
• a blade assembly carrying a blade and a flexible display and slidably coupled to the device housing;
• an actuator operable to slide the blade assembly relative to the device housing between an extended position and a retracted position;
• and
• one or more processors operable with the actuator;
• wherein the one or more processors, in response to receiving a notification presentation request while at least one application portal is being presented on a front-facing portion of the flexible display:
• cause the actuator to translate the blade assembly toward the extended position by an amount necessary to present a notification associated with the notification presentation request without resizing the at least one application portal;
• and
• present a notification identified by the notification presentation request on the front-facing portion of the flexible display without resizing the at least one application portal.

A method in an electronic device, the method comprising:

• receiving, by one or more processors, a notification presentation request while an application portal is being presented on a flexible display carried by a blade assembly that is slidably coupled to a device housing and movable between an extended position, a retracted position, and a peek position;
• translating, by an actuator operable with the one or more processors, the blade assembly toward the extended position by an amount necessary to present a notification associated with the notification presentation request without resizing the application portal;
• and
• presenting the notification on the flexible display adjacent to the application portal;
• wherein at least some of the application portal is presented on front-facing portions of the flexible display revealed by the translating and the notification is presented on other front-facing portions of the flexible display that were front-facing prior to the translating.
