EPIC Smartphone FAILS that people will never forget.

The built-in projector was well received, but everything else about the phone was dated and Samsung dropped it within months.

BlackBerry's first touchscreen phone had an innovative clickable screen but slow software and no Wi-Fi sank it.

Ambitious four-camera 3D phone, but shuddery motion, limited apps and a restrictive Amazon-centric setup let it down.

A dream modular phone that was cancelled, with thickness, cost and manufacturer incentives explaining why it likely never made sense.

The biggest and costliest smartphone mistake, with exploding batteries leading to recalls, cancellation and a $17 billion loss.
