There are definitely unscrupulous app developers on the play store, unfortunately. As a developer, they are getting better at enforcing stricter controls, but I'm personally very careful about what apps I download on Android too (just like installing files on Windows!)
For those asking about BandLab the app - as listed on the Play Store:
This app has access to:
Photos / Media / Files
read the contents of your USB storage
modify or delete the contents of your USB storage
-> so that you can upload audio files/photos/video, or download them
Storage
read the contents of your USB storage
modify or delete the contents of your USB storage
-> same as above, for local storage of projects to work offline, etc
Camera
take pictures and videos
-> for photo/video shouts
Microphone
record audio
-> for recording audio
Other
receive data from Internet
view network connections
full network access
-> for cloud access, projects recorded on PC/iOS/Web etc
run at startup
-> for push notifications
control vibration
prevent device from sleeping
-> so your phone doesn't go to sleep when recording your masterpiece!
Hope that's interesting to you guys!
