I was in a team making a personal diary app. At that point the app was complex and the cloud backend was dabbling in ES and ML for recommendations. Samsung approached us for an OEM bundling, overlooked the current version and was interested in the primitive alpha which was completely on-device. They found the recommendations impressive and set up more meetings (and fizzed out). The lead dev was incredulous and exclaimed it was a huge block of if/else, and I guess it has lots of bugs Java compiler allowed them to get away with.
