So I bought an 'Swees' Android phone recently, with ~150mb Internal storage + 4gb External SD Card.
I downloaded Android SDK manager on my mac, installed necessary packages and ran the 'adb' file in Terminal.
I set Default Storage Locaction to '2', (i.e. External Storage).
This was a success.
I have moved all my installed apps to SD Card (which I couldn't do before).
However, it seems I still have ~95% of Internal Memory used up.
When I download an app from the Play store it installs directly into the SD Card, which is what I want.
But when I install some apps (big file sizes) it will return an error, "insufficient storage space available".
I have >3.5GB available on my SD card.
Does the file have to be downloaded before it's installed on the SD card. And does it keep the downloaded file in Internal Memory?
I have no idea why else this is happening.
