I had 100mb free space on my phone but one day it suddenly dropped to 10mb & then to zero. I have tried clearing temporary files, restarted but nothing helps. I have absolutely no apps installed on phone memory except Microsoft preinstalled apps( only 300mb) but still the system grows continuously. Even if i free up some space it again reduces to zero after few hours. Anybody has any idea how to deal with it? I don't think the dumbs at Microsoft will ever gonna fix this.
