really weird unity behavior please HELP????

Good day all, I have a scene with a simple touch to destroy game. Balls show up at random points on the screen and the player would touch/tap to pop them. Other items such as knives and bombs will also be spawned on the screen. The point of the game is to tap the balls and avoid the knives and bombs, if a knife or bomb is hit the player would lose points - a relatively simple concept. This is what is going on - it works great when I test within the engine, but whenever i build and push it to my android device for testing everything goes haywire. Firstly, I created OnMouseDown () c# scripts for the balls, knife, and bomb prefab, basically indicating when touched/clicked add or subtract points from the score, and destroy the gameObject. Whenever I test on the android device, the knives either spawn and do not show, or just don't get instantiated at all - although it works and gets spawned in the editor/unity engine. Additionally, whenever I tap the screen away from the bombs, or pop a ball, the bombs also get destroyed, BUT ONLY IN THE ANDROID BUILD. When i test in the editor it works perfectly. I rebuilt the entire level from scratch trying to identify anything which might cause this to occur....and I am absolutely stumped. I literally have no clue what is going on. I cannot understand why the knives don't get spawned/instantiated. Can anyone help me with this?
