Part 1: Why Android App Not Installed & How to Fix?

Case One: Scarce Storage Space

One of the major reasons as to why this error appears on the screen of many smartphone users is due to them having insufficient storage space. If you feel that your smartphone has a lot of stored messages, music, videos, and photos, it is time to change this. Data is stored in the internal memory of your smartphone, and as you already know, it has a storage limit just like a computer. Deleting some unnecessary files might aid in combating this error. (It is recommended that you specifically delete those applications that are taking too much space.)

How to Fix:

You can follow the three easy steps to getting rid of applications taking too much space:

1. Visit "settings" section.
2. From the list of options presented, select either "apps" or "application manager".
