Hey all i got problem with my phone, and i have been searching for a solution for over 2 months and cant find any SO let me explain whats going wrong
I got a Samsung galaxy note 1 GT-N7000 (16 GB) okay not bad for an old phone
MY ROM is CM 12.1 (5.1.1) Lollipop Thats working good for now
The issue is That MY internal storage is divided into 2 partitions
1. Internal storage
Size = 1.97 GB
Free = 905 MB Notice i only have 2 games and 3 apps ONLY
2. Internal storage (also)
Size = 11.07 GB
Free = 6-7 GB
3. SD card really doesn't matter i have a bunch of cards that's not the issue
.So I know that the first internal storage is the device storage and apps and stuff like that and the second one is my media and file storage okay i got
so lets say my phone is compatible with a 2 GB game on play store a free to play game and when i download it, it downloads 650mb then the games opens and begins to extract the file into my 1.97 GB partition
