I have a Sony Xperia M4 Aqua. It's the "8Gb" internal storage but as we all know most of that is taken up by the android OS and pre-installed apps (which can't be deleted/uninstalled). So my question is this, can I put all these space taking apps and the android system into a compressed folder (7z, zip or rar) and still run my phone as normal? Would it allow the android OS to run without problem from the compressed folder? And ultimately, which is the most important, will this free up some space?
