I have an Optimus V (Virgin Mobile) running IHO, a port of CM7. Gingerbread. I try to install apps from the market, and it tells me there is not enough space. Also, sometimes (more often than not) while side-loading apps it says app not installed. I move almost every app that can be moved to the SD card, could that be the problem? I'm thinking that maybe the phone doesn't see the app as being stored on SD, even though it is, and it's putting those unused MBs into the used memory value for the market and such. My phone doesn't have a lot of internal memory at all so this is a problem if I want to have like, five games installed. :/ I've tried wiping cache, and dalvic cache via clockworkmod recovery. This also happened on an earlier rom, but I've wiped data since then and started fresh. Anyone have any ideas?
