If you read prior discussions (sorry, no links this week) you discover your 16GB is partially chewed up by the OS. And at some revision of Android you lost the capability of moving apps to the external 32GB card.
This is not a bug. Google designed it that way. You bring up a good point here and there but should everyone learn all the ins and outs of the OS?
I have a Galaxy Note GT-N7000 (on 4.0.4) and I have had it for about a year. I have a 32gb SD card inside and have had since I got the phone. Recently my phone has had a couple of memory issues and I cant seem to find anything on the internet that resolves them.
The most important issue is that my phone will not allow me to access certain parts (gallery especially, also apps that use gallery) because it says I do not have enough memory. When I look in the storage section it lists my memory usage as below:
Total space: 11.07gb
Total space: 29.71gb
Free space: 26.77gb
The Note either comes with 16/32gb internal memory so even if I only have 16gb I should still have enough space to read my messages. I have deleted as much as I can but certain apps wont work from the SD card so I am unsure how I can clear anything more.
The other concern is that the SD card randomly stops being recognised and then the phone will recognise it again. Sometimes it wont happen for weeks. When it does happen it will last from 5 minutes to a few hours, though the longest has been a week (which was infuriating) The card works fine in a PC and, when the phone does recognise it, it works fine on the phone.
The main area I really need help with the freeing up memory so I can use my phone so if there is anything you can suggest that would be excellent. Sorry if I am repeating previous discussions.
