have you guys tried this app on the playstore?
https://play.google.com/store/apps/details?id=eu.codlab.int2ext
Root external2internal SD
I used it on my lg motion.
though, instead of switching my internal sd for the external micro sd like the app's developer claims it does...it unified both. so my phone doesn't even recognize my micro external sd card anymore. according to my phone it no longer exists.
but my internal memory is now 30gb of space.
I think it did this instead of switching sd cards because the lg motion's internal sd is emulated.
now, my lg motion had around 5.5gb of internal memory.
I had around or close to 3gb of apps installed. to check to see if external2internal app actually worked, I installed jet set radio game which is a 1.75gb game. yes I'm sure its a 1.75gb game even if that's not whats listed on the game's page on the playstore. after that I also downloaded a over 1gb game, super monkey ball 2 just to see if I would get a insufficient storage message from the phone. I didn't.
now, jet set radio alone should have caused the insufficient storage message since its almost 2gb on top of the 3gb of apps on the phone, but with supermonkey ball 2 included...trust me, that game is huge. over 1gb. even if the game's product page doesn't say so. there are post install downloads that need to be made....
anyway. no insufficient message from my phone which leads me to believe it works.
but,
but...Clean Master app states I only have 5.5gb of memory on internal and sometimes..just sometimes, gives me a insufficient/free space storage running low message. While system settings claims I have 30gb. but I think Clean Master is just plain wrong in not recognizing the change. because if Clean Master was right there would be no way for me to have been able to install super monkey ball 2 after already having jet set radio installed.
Those 2 massive games plus the already used up 3gb of apps already on the internal....it would be an impossible fit.
my phone would have burst from the seams if External2Internal really didn't truly work.
haven't tried this app on my mom's rooted lg optimus f6 yet. I will this Thursday.
p.s.
it took me 5 long hours to downgrade her phone from 12b to 10i, root it, and make it a part of her phone's system settings.
(-_-)
don't ask why. it wasn't my fault it took that long. nothing was responsive including my pc that night. multiple tries for every step. its a long story.
edit:
here is what my phone's storage in settings states:
INTERNAL STORAGE
TOTAL SPACE 29.71GB
APPS 5.14GB
PICURES,VIDEOS 3.26GB
DOWNLOADS 73.16MB
MISC. 6.53GB
AVAILABLE 17.60GB
SD CARD

"THERES JUST A LINE AND MY PHONE CANT SCROLL IT PAST IT." as if there's nothing there.
when before like any other phone with a micro sd card installed it use to say 32gb with 26gb free and available. AND SHOWED THE BAR GRAPH OF AN SD CARD.
though when I go into apps it states I only have 1.9gb available of free space for storage of apps.
i'll download a 2gb game as soon as I can to see for sure.
2nd EDIT:
OK! IT WORKS! 100% FOR SURE!
I DOWNLOAD THE KING OF FIGHTERS 2013 WHICH IS A 500+MB GAME AND I DOWNLOADED THE DARK KNIGHT RISES A 1.8GB GAME.
RESULTS.
IN SETTINGS,
INTERNAL STORAGE
APPS 7.60GB!!!!
which is impossible on a lg motion!
when I go into apps, it says
3.7gb used------1.9gb free
which is IMPOSSIBLE!
JUST LOOK.
THE DARK KNIGHT RISES 1.82 GB
JET SET RADIO 1.75GB
THE KING OF FIGHTERS 653MB
SUPER MONKEY BALL 2 366MB(NOT COUNTING THE OBB DATA WHICH IS LIKE 500+MB THAT GETS STORED IN INTERNAL)
ADD IN THE 100+ OTHER APPS ON MY PHONE....
it works.
