App lag and crash - need help with Profiler stats

Hii,

I’ve been working on a Unity and Vuforia AR app that allows

  1. displays object on scanning an image target

  2. allows changing between different textures for the object

  3. allows changing environment lighting

  4. plays object’s animations

The features work fine in play mode, but when i made my android build it always seemed to lag a lot and finally crash. I’ve tried reducing keyframes, removing animations completely, deleting other objects in the scene and keeping only the main one.

This is what i saw on the profiler today. I’m quite new to this and don’t know what normal values and sizes should be here, so can someone help me interpret this:

Thank you!!
