I need help with my xperia s, I've had it for like 2 years now ... it's a great phone btw 
anyway .... there is a screenshot for my internal memory
it says that only 1.4 Gb are free, but I'm only using like 10.09 Gb ! ( adding apps, pictures,. and so on )
please help because it's slowing down the phone :S
sorry if there are any spelling or grammer mistakes :S
and thanks in advance 
Well I would start by getting ES File Explorer app installed...
In that app there is a Tool (under system tools) thats called "SD Card Analyser" or something similar... that will show you exactly what folders are taking what space from your internal memory...
As it turns out, in my Acro S there is a presistant file thats related to Pictures thumbnails and it has over 1GB of size...
Try it and see if you can find the reason for it... DONT delete anything that you are not sure what is is for...
Alternatively you can go to Settings>Apps> and Clear Cache from Chrome, Google+, Instagram, Facebook, etc... those are apps that hold big ammount of Cache data...
