I was roaming around the the Taiwanese huawei site, and stumble over secret mode for Mediapad X2.
If you dial * # * # 2846579 # * # * a "secret mode" will appear, as far as I can see, there's are options for entering the bootlock key, update software, reset phone, and some other stuff I don't know the use of.
Might be useful for some.
No secret mode. The most of us have used this to get the bootloader unlock code when using the dc-unlocker software.
You can also start the dload with this. There are also other phones using this menu.
Samsung also had such menu to test the hardware components and display.

Hey all, I never knew about these particular codes before the blaze. They seem pretty powerful. Thought it would be worthwhile to document them. If you don't want this in the dev section, feel free to move it.
I used the phoneutil code to upgrade from stock, unrooted GB to stock, unrooted ICS when it came out. I originally thought the problem was my usb driver. I tried reinstalling that, and was still seeing errors when looking under Device Manager. Then theshowman posted the code and instruction on changing the modem/CDC properties, and BAM my phone could upgrade via keys.
To use these codes, open up your dialer and type whats under the "code" column.
Some of them open up into this black sceen with grey text which doesn't allow for touchscreen navigation.
If you use the back button with these, it will bring you to your HOME screen. To navigate back, hit the leftmost hardware button, and then "Back".
To select another screen, hit the leftmost hardware button and then "Select," and then type in the particular number, (i.e. "1" for Debug screen).

Thanks to kvswim over on the Verizon Droid Charge forums for a lot of these. I went through his list entering codes manually, adding the ones that worked onto this list.
I've googled lists of these codes, but lots of the ones I entered did not work. Feel free to post one if you find it.
1. Open the Shut off menu, press it for long and you will enter into the Safe Mode. Moreover, when you phone get poisoned or has small fault, by entering it you can repair your mobile.
2. Choose Setting - Safe - Hidden to protect, you can set two passwords for your Huawei Honor 6 for the sake of a more secure environment. And with the two passwords to unlock for logging in, you will enter into different application environment.
3. Lock the 3G or 4G network, and insert "*#*#2846579159#*#*" on the dial interface, choosing 7 represents network function setting, and 4 for network mode locking.
4. Freeze most of the software. Insert "*#*#2846579159#*#*", choosing 5 represents background settings, and 14 for opening the freezing process function switch. And then come back to the Settings - Application management - All. After that you can stop most of the software that you don't want to use. And you can restart it at any time you want to use.

Hello,
After getting my Gear S2 back from Samsung service (I tried to wash it via the faucet water stream, it entered an infinite reboot cycle and then died - IP68 compatible huh?) I turned it on and it appeared to enter some sort of Service Menu. I haven't left this menu (nor do I know how, except maybe a factory reset?), but I would like to know how I could reenter it if I wished to, in the future. Googling for this yielded no results, and that is shocking. I wanted to post an image showing this menu, but I'm not allowed to since I've got less than 10 posts.
Thanks.
Should be able to just upload it to a photo service, like imgur and just pasting the link as text, if you wish to share it. Interested in what it looks like.
Hi. Looking for this menu in the web, i found the method for the Gear 2, and *i think* is the same. I tried succesfully in my Gear S2.
Just go to the dialer and press: *#0*#
and you can enter to a menu titled TESTMODE
You can exit from this menu pressing twice in the upper button.
Greetings.
Pressing the upper button twice does nothing. In fact, I'm unable to exit this mode even with a restart or a factory reset (via Gear Info -> Reset). Here's the link, delete the spaces.

I brought it back to the service and apparently they forgot to flash it. That was a default service Tizen that ships from the factory. It contains tests and it's supposed to be overwritten once the mobo is replaced.

Thanks for the info about the Test Mode. The Sensor screen was fun.

Good!. I tried to find this menu but i only guessed that is for developer options or something like that (because a lot of tizen icons).
Also i tried some codes for Samsung devices and found some of them work in my Gear S2 (use at your own risk):
*#06# Serial Number
*#0*# LCD Test Menu
*#1234# Version Info
*#12580*369# Main Version
*#0228# Battery Status
*#0*# General Test Mode
*#2663# Touch Firmware Version
*#0283# Audio Loopback Control
*#9900# Log Dump
*#34971539# Camera Firmware Update
*#7353# Self Test
Greetings
Did anyone noticed...
I find an easy way to input these codes; plus others that in the dialer doesn't work.
Go to Settings>> Gear info>> Device>> Software version (push 5 times the button) A system ui with a different dialer let you input codes- it's like when we try to get the developer options on android phone.
Hope it helped!
Folks,
Anyway to completely disabling safe mode in Android? The target is to disable any possibility of getting into safe mode (e.g. by pressing hardware buttons).
It is Android 9 on Samsung phone (ONE UI 1.0).
Do a WEB search
"deactivate" safe mode on android at DuckDuckGo
DuckDuckGo. Privacy, Simplified.
duckduckgo.com
I did a solid research! No relevant method found. It is about complete disabling. The aim here is to prevent any user of entering a safe mode by any means. Not just "escaping" safe mode to a normal mode. Do you mind the difference?
