I have a chinese table running 4.2.1 it is rooted. I have strange issues with storage. for one it is suppose to be 4 gig . it lists 2 internal storage in the (storage app) one is 500meg for the system files and the other is 1.2gig in some file manager it is called SD storage from the storage settings if I select erase sd card it clears out the 1.2 gig internal storage. I have set thru ADB commands the default app installation location to external...which puts it in the internal storage (1.2gig)but at least it isnt the 500mg partition. I cannot set it my 16gig sd card. I have also notices some filemanagers cannot delete or add files/folders to ext sd. but the build in one can. I can live with some of these issuses. but I have movies on the ext sd , uHD player can select videos from the ext sd and can play them but it doesnt work well. So I tried several movie players..android player and flvHD player both will list internal and SD but the ext sd is not listed. WTH is going on?
