Can confirm this keeps happening, my nothing 3a has one week. Flip to glyph function randomly unmute the phone, for example with whatsapp or even phone calls when the phone is face down (with flip to gryph enabled) apps keeps making sounds randomly.
And, with IP calls like Whatsapp, flip to glyph LEDS dont work when is activated, whatsapp calls don’t boot the glyph leds.
