I'm coming from a rooted Samsung S4 to a non-rooted Huawei P9. With the rooted S4 I could do anything at all, the stock P9 is extremely restricted. I want to stay with stock because it's a phone that's been loaned to me and I don't want to risk breaking it, and I'd like the Android 7.x over the air update in a few months without having to unroot.
I would prefer not to mount the external SD as internal memory, as it's slower. I've tried creating files, deleting files, and changing permissions, I can't do anything.
Basically I would like to be able to do two things:
- Add and delete files to the external SD card using a file manager, such as Root Browser
- Have Bittorrent Sync (or other apps) write to the external SD card
I know Android security was ramped up around Android 5, but this much restriction is crazy. Is there a way around to do this working within the stock OS? I may just have to give up on external SD, it seems pointless to have it right now.
