My partition of data's space is lack,So I move the app from data to internal sdcard, the phone deny this option. Now I move app to external sdcard,and my internal sdcard only use 1% and I do not know how to utilize it,my photos store in my external sdcard.
After I delete partition 18(/data) and 19(/storage/sdcard1) and recreate them,the phone can not start up.
After I move /data/data to /system/data and link /system/data to /data/data,the phone can not start up.
After I move /data/dalvik-cache to /system/dalvik-cache and link /system/dalvik-cache to /data/dalvik-cache,the phone can not start up.
After I move /data/app to /system/data_app/app and link /system/data_app/app to /data/app,the phone can start up,but all the app can not upgrade.And I can not debug my developed app in my phone.
Now I move some apk from /data/app to /system/app,some app can not work,I have to move them back.Some app can work normal,but when the app update,the size of /data still decrease.
How can I use my internal sdcard or how can I store all my app in my phone's internal storage,I don't want setup the app to external sdcard.
