First, the way Android works with storage pains about 98% of the users today. While it's too late to help you avoid this, I always advise to get Android things with 1GB RAM (or more) and 8GB of main storage (or more.) Android does NOT automatically use the SD Card space. Now you know.
OK, There are many articles on finding and clearing that downloaded space. You left out if you got this via the Play Store so I'll make that assumption.
Hello, my name is Tim.
I recently tried to download Fifa 16 ultimate team for android on my phone, in the last 4% of downloading the game, I got an error saying I don't have enough space in my phones storage.
The problem is, is that when I started downloading the app, I had 1,6 GB left, and at the end I only had 300MB left... And the Fifa app hadn't even installed because of the problem I stated before.
Now I'm stuck with 300mb storage and while I don't even have the App I wanted.
I've searched everywhere on my phone, even using the "Clean Master" app that I use to clean up my phone regularly. I can't seem to find the FIFA files that have taken up to 1,5GB of my storage. It's just gone, it hasn't even been fully installed yet it is taking all my precious storage that I have been cleaning up time and time again!
Please someone help me, it's annoying me to death.
