if you do the crime then you need to do the time. if you installed applications from the Extra-dev and testing without knowing what you are doing then you need to do your time do uninstall and stop asking for help here repeatitively. just uninstall every apps you installed from devel and testing then your space should be fine. and if it doesn't work then just reflash it using flasher or NSU. blaming Nokia root space issues won't make anything better okay. blame yourself for being ******edly stupid for not knowing that those repos apps are not risk free. it's been warned before you installed it.
