Hi, I bought my S6 yesterday and have one question. I had SIII, S4 and S5 rooted and there wasn't a problem delete annoying sound like boot up sound, charging sound and camera shutter. Now I"m going to not root my S6 yet but the sounds are very bothersome.
Is there something like temporary root until first reboot which doesn't trip KNOX and allows me to delete the sound or any another way how to mute them?

I created tasker profile which switches to vibrations when the camera is on but it always vibrate. And I didn't found any way how mute charger sound which it very bothersome for me.

Thanks
