If you want to be safe. Keep it asking you everytime. Or risk it for a biscuit, but that will open you up to getting your data sold to add companies. So they can bombard you with adds you don't want don't need and take up loads of processor speed. I close everything. Force stop everytime and full close. On top of that I use hidden software on all samsung phones to stop my location, camera, microphone being used against me. Most of the spywear is GOOGLE. IS your phone on contract. Or do you own it. If you own it. You need to access secret developer options.... then access tiles, add dead switch.
