Hello,
I have a problem with the amount of RAM that I can effectively use for applications.
The product specifications show that the xperia J has 512mb of memory.
Now I know that some of this ram is reserved for the android system which leaves me with 321mb (as seen in the app settings menu)
However it seems that I can only use much less than this 321 mb and I dont know where all the memory has gone 
In the active apps menu I can see the ram usage of the different apps but if I sum these up I only get to 175mb used, which means I should have 146mb of free ram. but as u can see in the screenshots it says that I only have 60mb free.
Can someone tell me what happened to the missing 86mb? how do I get to use it?
The reason I am trying to figure this out is that my walkman app keeps crashing when I am surfing on internet sites that have many pictures and stuff (phone seems to run out of memory and stops playing the music)
The screenshots were taken 1 hour AFTER restarting the phone.
Sorry, I forgot to say this
