Been interested in plenoptic cameras for a while. Here's my guess: 1. Focus after the fact was a nothingburger to consumers. Likewise only niche enthusiasm for 3d. 2. Plenoptic cameras require a lens array or equivalent in the optical path. Phones are extremely constrained on depth. 3. Phone makers realized that if they wanted different focal lengths, the most simple route was to put two compact cameras on it. 4. You can't really go below 8x8 pixel "subtiles" with a plenoptic lens array. So you're giving up a factor of 64 resolution at least. That's a heavy cost for features users are very apathetic about.
