I just got a new Virgin Mobile LG F3 phone from Amazon and updated to LG720ZV6 (after bricking my first LG F3 and after several days not being able to unbrick). I rooted using saferoot and restored all of my old programs with Titanium backup and re-linked to SD using Link2SD. Looking at the storage info within Link2SD I see that I only have 2% of my /system storage free (35 MB of 1.19GB remaining). This can't be good. What are the safest ways to free up storage in the /system folder? I'm pretty wary of bricking my phone right now.
(5 GB for sdext2 using ext4, the rest for FAT32 partition.)
