In the end, I just wished that there should have been a software that could support or give direct permission to choose on which partition we can install game. Like in windows we can select a drive to install games and applications other than the program files.
Apart from that, i guess the preenv games are taking too much space on the memory for installable applications, so could you please tell me steps how to transfer or even install preenv games on the mydocs or 23 gb space? (also, while launching any preenv games, like assassins creed, where is the button to shut it off - ingame, ie; to exit to main menu.
Anyways, the methods described for partitioning is way to bouncy for me and therefore i might end up bricking up my phone, so it is a no go for me. If in future, i will require it then i will try it for sure.
