The meaning of being able to choose the storage path is that after clicking the installation package, it will prompt whether to install on the phone or the memory card, saving the time of dragging the software again.
Operation method:
1. Use RE Manager to enter the system/app folder
2. Change this folder to read and write
3. Drag the software I provided into system/app (first remember the software name is PackageInstaller.apk), it will prompt whether to overwrite the file, choose to overwrite
4. Find PackageInstaller.apk, change the software permissions to rw~r~r (that is, first row read and write, second row read, third row read)
5. Delete PackageInstaller.odex (if not deleted, it will FC, that is, installation will prompt that some software (RE or package installer) has stopped running)
6. Restart the phone
