Its not that simple, the cache increases and fills up the phone memory, so like this, no apps can be installed, no files can be downloaded(all downloaded files are stored in phone), can't transfer files via bluetooth, nothing will happen as the phone has run out of memory, for Lumia 920 its ok as internal mem is 32GB, for 620 and 820 users, its hell. Hell you can't even use a browser as there is no place left in internal memory, its a massive bug that literally breaks your phone
so sorry to hear about the poor wp8 using people. anyways in all seriousness ill suggest you play the wait and watch game.
