Apple Lossless Audio CODEC (ALAC), made some minor changes in iOS beta 7.1 1 for iPhones, and among them is one that prevents us from using some of the tones for texts available in the Settings application. As you can already see in the video clip above, in the Settings application the first tones have exactly the same sound, no matter which one you choose, but the rest of the ones available in the application play different sounds and can be used. If you encounter this bug, you have no way to solve it and you will have to wait iOS beta 7.1 2.
I don't think it's a very good idea with the beta versions... The terminal suffers from all these defects that at some point will even affect its components... I speak from my own experience 🙁
