Apply a heated iOpener to the bottom edge of the display for about one minute.

Gently insert an opening pick between the display and the "recent" button, no more than 0.5 (~12 mm) inches deep to avoid damaging the display.

Keep a close eye on the button's ribbon cable as you insert the pick. The cable is fragile and very easy to tear. If the pick is hard to insert or the cable starts to stretch, apply more heat.

Leave the pick under the display to prevent the button from re-adhering to the display.
