SpringSounds, an old tweak of mine, make its comeback to be better than ever !
The whole code has been rewritten in order for the tweak to be more reliable and perfectly working on iOS 10+ ! Currently the tweak allow you to change the keyboard, lock, photo shutter, plug, received message and sent message sounds with more being planned.
It also support custom sounds created by the community (documentation available here as well as within the tweak settings).
You can get it for free on the Packix repo.
Be sure to leave a review ;).
Enjoy !
