you can go to these 2 settings:
- 1 : go to phone settings, personalize, Sound, then you can change it. Make sure you placed your soundtracks into the right folder.
- 2 : go to "theme" app, edit current theme. But this one you can only download from theme store, cannot add local soundtracks.
I installed HTC gallery 9.51 on new HTC 10 but when I modify a picture with the photo editing software, I can't save the modify photo : "Error saving..."
I also modified rights to let HTC Gallery modify storage.
