I forgot which phone company did it, I remember them dropping the feature after a generation, but one of their phones was advertised to lock the screen if it detects a second pair of eyes were peeping into the screen, like someone behind you looking over your shoulders.

The minimal bullshit phones I’ve recommended for friends and family are always Sony Xperias.

You’re right, I confused my iPod touch 64Gb with the 4. The 4S was the first iPhone to offer 64Gb of storage.
