I think you missed the point of his post. His issue is that the numeric operations the phone executes to run the LLM is producing garbage. Arguably this could break all kinds of neural networks, such as voice transcription. He’s not complaining that the LLMs are themselves unable to properly perform math.

Sadly, at least in the North American market, Google’s Pixel phones are basically the last good phones you can reliably install your own ROM on.
