I was playing a game on my phone and I received a strange screen notification similar to an alarm notification but it did not have the dismiss or snooze button but the color and style was the same as an alarm pop up otherwise. Its said "contact. H/" and following this were several other letters,numbers, and symbols in random order. It had four or five lines of this. It popped up and disappeared without me doing anything. Has anyone experienced this or know what this may be.
