Is there any way if i can put a lock on gallery? I know i can do for apps and gallery as well but i want inside folders alao to be locked specifically..is that possible? Inside this stock gallery?
As of now, there is no such option to lock specific folders in the default Asus gallery app.
You can either lock down the whole app or hide private folders you desire.
The file manager has a Hidden Cabinet.
You can set a password or use a fingerprint/face to access to the contents you had locked.
