I can see this is a very important think and has been asked by many folks, and I've been looking around for answers but couldn't find any real solution.
So, it seems that android platform deny you from installing apps when /data partition is under 10% of free space. For me, it means that if I have 500mb free, I still cannot install a 300kb app. Sounds ridicule, but they put this limitation among us. Searching on this forum and out, the only "solution" people give to us is cleaning obsolete files. It's not a real solution so I'm thinking about another way to solve this threat.
First, it looks that nobody knows how to remove this 10% restriction, that would be the real solution. so I was thinking about faking the /data partition total space, for example: mine is 5,4gb total space, so if I could make my phone think it's kind a 1gb total space, my 10% restriction would be less than it is now, kind a 100mb, so I would be able to use this 400mb that isn't occupied (100 + 400 = 500).
But I don't know if it's possible so I'm asking here.
I'm not asking how to change partition space, I only want to fake the total space that is shown, not to real change it.
I'm sorry if something is wrong, it's my first post, so if I did something wrong, tell me and I'll fix
