Here I've got Xiaomi Mi 9 and let me show you how to activate test mode on the following device
0:12
So we've got two methods to enable it. At first let's open the phone dialer and enter a secret code which is asterix pound, asterix
0:21
pound, 64663 pound asterix, pound asterix. And now we are in test mode where you can perform a virus of truly interesting tests
0:31
as you can see the whole list is truly wide. You can perform for example vibrator test, keyboard test, you can check notification
0:39
light, touch sensor, display, receiver, speaker, main and top mic, headset test, proximity
0:45
sensor and all the others also, light sensor, OTG, charger test, you can pick also rear
0:53
camera or GPS. And actually whichever feature is not working correctly you can test it here
1:00
So let me show you for example display test. So it's red, it's working correctly
1:08
Then we've got the green, it's also correct and blue, it's working as well
1:13
It passed. Now we are in receiver test. So it's 47, it passed as well
1:24
So now we just make a speaker test and it also passed
1:28
So that's it. This is how you can, as you can see here, you've got the solution
1:32
So it all passed. You can also check all the other features
1:36
But let me go back for now. Okay. And you can also access this super test mode through the settings
1:43
So at first you have to open the settings, find and pick about phone
1:47
That's actually the first step. And here, once you see kernel version, simply keep tapping on it until you are in test mode
1:54
And here you can test all those features that we opened previously
2:01
So you can pick receiver, speaker, main link and all the others. It's exactly the same mode, just a different way of enabling it
2:08
So that is all. This is how you can activate test mode in your device, in your Xiaomi Mi 9
