Toggling a Glyph Frame only switches the frame on and not off again. Test on a nothing phone 3a. Here is some example code: ```java GlyphFrame.Builder builder = mGM.getGlyphFrameBuilder(); GlyphFrame glyphFrameA = builder.buildChannelA().build(); mGM.toggle(glyphFrameA); try { Thread.sleep(1000); } catch (InterruptedException e) { throw new RuntimeException(e); } mGM.toggle(glyphFrameA); ``` The after the second toggle the frame stays on.
