A normal HTC Desire 500 has an internal space of 4 gigabytes.
What is interesting is that even if you don’t store music or video files, there is a folder called “other” which has around 2-3 gigabytes, which is a lot.
So how to clear the memory and make more space?
From what I’ve noticed, those 2-3 gigabytes are actually occupied with the pre-installed applications. All you can do is to do a total reset for your smartphone and try to move all your applications on a SD-Card.
