Mike discovered that an app uses an AlexNet TFLite model every few seconds to identify which game you are playing

AI summary

Mike's inspection revealed that an app runs an INT8-quantized TensorFlow Lite model on 960×540 images every few seconds to determine which game the user is playing. The model is named alex.tflite and is in fact AlexNet, with a structure that appears to follow torchvision.models.alexnet. It performs nearest-neighbor feature matching against a database, but according to Mike's observations it fails to work in 99% of cases, and the results are discarded before the consent authorization step.
