There are no custom ROMS at this point for the Samsung Exhibit II 4G but there are some people working on doing this however it will probably be "some time" before we see a custom ROM come out.
I've installed a fair amount of apps (but hardly any games which I guess can get pretty big) and well I've done nothing 'special' in terms of trying to move them and I have tons of memory on my phone. So maybe trying to move them to SD (and them going to the phone's internal SD instead of external SD) is a bad thing. I don't know.
I mean the two internal storage options are like roughly 1.07GB and 1.62GB so I can't imagine anyone filling them up with apps? I mean how many apps do you have that you are filling it up?
All I know is I have what seems like a lot of apps and yet I still have plenty of space left.
Course that doesn't help those running out of space lol but jeez I think you are installing too much.
The real question I think is how to force apps to install to the external SD and not the internal SD and I just don't know the answer to that.
