Clear cache! =D

And I was wondering why there was so much memory used on my Android phone! Especially Instagram seem to collect a huge cache. I had over 5GB cache collected by Instagram on my phone! =O

Luckily not many other apps on my phone seem to keep so huge cache. I would call that as a design flaw, to not restrict the size of software cache in any way. I do not know if there are similar issues on PCs.

Anyway, cache can be useful to save us from loading data every time when visiting the same web pages, but cache also can take a lot of local memory.
