On a hunt for the mysterious home not-button, we dig into the display despite previous... difficulties.

Luckily this fused display/digitizer peels up from its frame with a decent struggle, but no damage.

Hoping to find some hidden detail under the display cabling, we peel it up and find—zilch. No model info and no visible pressure sensor. Better luck next time.

We did, however unearth some chips!
