Description
After compiling the example Android app for Phi-3 I've downloaded the model file from hugging face seperately and placed it in /data/data/.../files, however when trying to run the app always crashes it says something about "downloading model for app..." Then goes to "model exists skipping download" then immediately crashes. Using logcat of Android studio I've narrowed the error down to this line in the log:
Deserialize tensor model.layers.31.mlp.up_proj.MatMul.weight_Q4 failed.tensorprotoutils.cc:904 GetExtDataFromTensorProto External initializer: model.layers.31.mlp.up_proj.MatMul.weight_Q4 offset: 2628268032 size to read: 12582912 given file_length: 2354700288 are out of bounds or can not be read in full.
Any ideas on how I can fix it?

Research direction
Start by inspecting the Android example's model-download and model-existence handling, then compare the Phi-3 file's size with logcat's reported file_length, offset, and read size. Reproduce the failure in Android Studio using logcat; done means the app loads Phi-3 without the tensor deserialization or out-of-bounds crash.
