Here I have HTC Desire 5030 and let me show you how to use secret codes on the following device
0:12
So at the very beginning let's start by using a home screen, tap the phone's dialer right
0:16
here, the phone icon and let's use the keypad. So let's start by using the HTC function test
0:22
Let's input star hash, star hash, 3424, hash star, hash star
0:39
As you can see HTC function test just pops up, here you have to accept the following
0:43
information and now you can use some test of your device. For example you can test the audio, bluetooth, charger, light sensor, vibration, blacklight
0:53
button and other stuff. Let me just for example test the vibrator, let me tap run, choose start and as you can
1:01
see you can test the vibrator on the device. Does it work normally
1:05
Let's tap yes. Let me choose stop and let's go back. You can also select all and perform all tests, you can also choose more and here you've got
1:16
some more options for example you can go into save mode, you can accomplish the hard
1:21
reset operation and you can see the device information. If you would like to go back from the following menu, let's use the back arrow a couple of
1:29
times and let's use the phone's dialer again. So now let me open the testing menu, let's input the following secret code, star hash
1:42
star hash, 4636, hash star, hash star. As you can see the testing menu just pops up, here you can navigate by tapping appropriate
1:52
options, let's choose phone information, here you can read all important specification about
1:57
your device, you can run a ping test, read the signal strength, location, gs sim service
2:04
roaming and other stuff. You can also turn off the radio and choose more key in order to select radio band, view
2:10
sim address book, view fixed dialing numbers, view service dialing numbers, get PDP list
2:15
or enable data connection. So let's go back by using your back arrow right here
2:27
Let's use back arrow again, let's choose usage statistics and here you should find the statistics
2:36
about your application, you can read the last time use or usage time
2:40
Let's go back again, you can also choose wifi information and here you can use the wifi
2:44
API, when you can disable network, disconnect network, enable network, get configured networks
2:49
or get connection info. Let's go back again and choose wifi status, here you've got the statistics about your
2:55
wifi, you can also go back and choose wifi config and this is the list of configured
3:01
networks, you can read the statistics and specification about your wifi. So let's go back again, let me quit the testing menu and this time you can try to open the
3:11
calendar info, so let's use star hash, star hash, 225, hash star, hash star
3:21
And in some devices, in some HTC devices you can check the calendar information, in some
3:26
not, it's worth to try. Again let's open the Google Play services mode, so let's use star hash, star hash, 426
3:37
hash star, hash star. As you can see Google Play services just pops up, here you can choose ping, connect, disconnect
3:45
or events. Let's go back, this time let's open the debug UI, so let's use star hash, star hash, 759
3:55
hash star, hash star. As you can see debug UI just pops up, here you can change the OEM mode, you can view
4:03
clients ID's, read the information and do some other stuff. Let's go back and at the end let me show you how to check email number by using a secret code
4:13
It's very simple, let's just use star hash, 06, hash and as you can see the email number
4:20
just pops up. So that's it, let's tap OK to close this window and right now you can use your device in a
4:26
normal mode. So thank you for watching, please subscribe our channel and leave thumbs up under the video
