HexAnima 1.2.2

HexAnima 1.2.2

Snapdragon 8 Elite (Hexagon V79, Galaxy S25 and similar) support is withdrawn. It was experimental in 1.2.0 and 1.2.1. Testing on a Galaxy S25 showed that it is not reliable with the current NPU kernels:

• after an interrupted run the NPU matrix unit is sometimes silently unavailable, and pictures come out as colourful blocks (a one-tile self-test returns 0 instead of 32);
• large sizes (about 4800 tokens and more, for example 960x1536) come out as colourful noise on top of a correct picture, even when the matrix unit works. The same sizes are clean on Snapdragon 8 Gen 1 / 8+ Gen 1.

The app now reports 8 Elite phones as not supported again, the V79 files are no longer shipped (the APK is 3 MB smaller), and the README says so. If you were on 1.2.0 or 1.2.1 with an 8 Elite phone, there is nothing to do except to uninstall the app. Nothing changes for Snapdragon 8 Gen 1 / 8+ Gen 1 phones, you can install over 1.2.1 and keep your models and history.

Supported chips: Snapdragon 8 Gen 1 / 8+ Gen 1 (SM8450 / SM8475). A port to other chips (8 Gen 2, 8 Gen 3, 8 Elite) is not planned in the short term.
