And it seems to happen either with stock rom and Cyanogenmod. I'm with CM right now.
What a friend did was uninstalling all apps, leave those really useful and avoiding updates at all, but I don't think that as a solution.
What can I do? Thanks.
It seems that whenever I install application updates for my installed applications the ram, or internal storage is consumed, until the point that all is used and doesn't allow me to download more updates, nor install more applications. Moving some applications to SD just leads to the same result: the ram is eventually saturated again.
