and now let's use those numbers 610 and hash. As you can see the hidden mode just pops up, here you can navigate by tapping appropriate
options, you can choose here the device test, so here we've got SAAT, you can use auto test
or manual test, let me use the manual, for example you can test your speaker, your vibrator
but also other stuff such as motion, loopback, camera, LED. Let's go back, you can also use here some optional test, for example the IDS, you can
