 Oppo (F5, F1s, A57, A37f)

We tested some devices and discovered that some smartphones automatically turn off accessibility services due to device settings or battery saver and security apps. Here’s a solution we’ve found for some Oppo smartphones.

(F5, F1s, A57, A37f)

1. Tap “☐” button (bottom left button)


2. Pull down the NALA app window


3. After that, there will a “Lock” icon appearing on top left corner of the NALA window — then it’s done! 😃
