App not installed android bug

I have created a basic security camera simulator.

the only scripts is a series of 3 scripts so far duplicated as follows.

using UnityEngine; using System.Collections; using UnityEngine.SceneManagement;

public class //scene_name : MonoBehaviour {

 // Update is called once per frame
 void Update () {
     if (Input.touchCount == 1)
     {
         SceneManager.LoadScene(//scene_number);
     }
 }

}

as shown when the player taps the screen it changes scene, but thats not why im here. ive come because of an error im receiving when i port the game to my phone.

It says "App Not Installed" after I had reached the 90MB mark of content. the first couple levels are 29mb and after I optimized the others the biggest its 40mb.

I decided to try removing levels as I went on, first I removed the fourth level, Still Couldn't install even though the first three levels worked in an earlier version. I removed the third level and it worked. I checked my optimizations and found that it worked incredibly as the game was functioning at a smooth 60-100fps rather than 15-20fps. But for some reason it does not install after the third and fourth levels are enabled. I thought it was an issue with storage, but I checked my player settings and I did what others had been told and set the Install Location to automatic, I kept the write access to External, kept all factory player settings and it could not install still. Then I thought it couldn't compile my scripts and it was causing it to fail the install or cut it short, but then I remembered Unity would have said something to me during debugging and before building more or less during before play testing the levels.

all previous versions worked, but then when I reached 90mb it just started giving me that Error.

im using a ASUS Zenfone 2E with Android Lollipop.

if anyone can assist with this issue it would be greatly appreciated.
