Manage Device Administrators (Enable Android Device Manager) - Honor 8 Guides, News, & Discussion

Manage Device Administrators​On most Android devices, you assume Android Device manager will work without having to set it up. With the Honor 8's device administration security features, one more step is required.
Device Administrators
An app with Device Administrator activated with be able to perform actions like:
Erase all data
Change the screen-unlock password
Set password rules
Monitor screen-unlock attempts
Lock the screen
If you've ever tried an app that needs to perform one of these actions, and it's not working properly, it's probably because you do not have that app activated in your device administration settings.
Activate Device Administration Permissions for Apps
To access the device administrator menu, go to Settings > Advanced Settings > Security > Device Administrators
One app that you'll find is not activated is Android Device Manager. If you want to use all of the features like remote locking your device or wiping your data, you'll need to activate this app. This is an important security app and is a life saver if your phone ever gets stolen. So make sure you activate it.

I can't activate any device adminstrator in Settings > Security > Device Administrators. When I hit “activate”,It just move back to the list screen and nothing happens, every checkbox remain unchecked.
I think this is due to the rom customization,which rooted the device initially.
Is there any way to activate an app as device administrator other than click "activate" within settings, e.g. by editing some files?
thanks!

you have to go to battery settings and choose the app you want to not close after the screen goes off, then you can activate it and will stay active

[Q] Windows activation

Hello, i have a little problem, it's shown on the pic
How to fix?
It shouldn't be necessary to activate the Developer Preview release.
Anyway, you try to use this product key (provided by Microsoft) 6RH4V-HNTWC-JQKG8-RFR3R-36498.
If that doesn't work, check the system time and ensure it's correct. Otherwise...try that new "reset without touching my files" thing (using the above PK if requested).
All developer versions are pre activated. You need an internet connection. Then just go to activate in metro control panel options.

I wand to activate to enable personalize in metro control panel
My time and date are right and synced with time.windows.com
I tried reinstalling all three versions of OS, the problem is the same
And on notebook activation was successful at first launch
May be it because of BIOS strings such as model, manufacturer? I had to change them to avoid using smbios.plist in hackintosh, but I think, it isn't. Any other variants?
Any ideas pls?
On the metro control menu, the first option should be activate windows. Just make sure you have internet connection and you should be good.
It could possibly be due to upgrading from a 'hacked' win7 pre-install. Try reloading and selecting " Do not keep User settings"
On metro control panel the same problem. Internet connection is active (i'm writing from that pc), and this is not ok
I'm installing from Windows Setup partition.

[APP][NO ROOT] Tethering Manager is back!!!!

This app disappeared from Playstore a while back.

Old devices make really good mobile wifi hotspots and portable media servers(for devices that support this functionality). I wouldn't splash $300 on a new device just to do this and chances are I'd have more face time with my new device than I'd do with the old one. That said, I'd like to have the ability to turn the hotspot on and off without having to fiddle through the settings each time and to that effect, this app also comes with a widget.
HOWEVER: The developers of this app have discontinued it's support. This is the response when I mailed the support team:
Hi,
Thank you for your email, unfortunately,
supporting this app is discontinued and we
pulled it from Google play due to changes in
Android OS...
Best regards
The main issue is that the wifi network security options JUST DON'T WORK!!! You'll set up the hotspot fine; Enter the SSID, choose the security option etc. But when you activate the hotspot, it security is set to OPEN. You have to manually change the security each time which is a nuisance.
Possible reasons for this could be because I'm running a nightly build of CyanogenMod 7.2. The wifi tethering has only two options for security; Open and WPA2/PSK while the app has 3; Open, WPA/PSK and WPA2/PSK. If the developer is comparing a selected index rather than a selected item to the phone's options, choosing option 3 in the app(index 2) would pass and invalid state when compared to the phone's options because they only go as far as option 2(index 1). This is why the setting is set to open, as a fall back because trying to set to index 2 failed. I found this to be true when I selected the second option(index 1) in the app which is WPA/PSK. After the hotspot is active, the security is set to WPA2/PSK which is the second option(index 1) in the tethering options.
If any of you have used this app, then you'll know that there is no better app available. Let's just hope that the support for the app will start again soon to fix this issue for CyanogenMod users.

"Features" missing from MM, after update.

I've updated from KK to MM (Note 4 f version).
I seem to have lost certain features from the "upgrade"
1. Can anyone recommend a multi window app, that wound allow me to add custom apps to the supported app list. So I can use them in multi windows?
I've used this in the past https://play.google.com/store/apps/details?id=com.bjbinc.mwmphone but it says I need to be rooted. Which I am.
I don't think it's compatible with MM.
2. Is there a do not disturb mode within MM, that allows you to block mobile data between certain times?
I used to use it in KK, to block data through the night, but, MM's version just seems to block sounds etc.
3. When using KK, apps like Clean Master, used to allow me to block apps from secretly starting up and allow me to clear cache/junk.
Since updating to MM, Clean Master and other apps I've tried all fail to do either.
They appear to clear the cache/junk, but if I reboot it's still there.
(At the moment I'm using "App Settings" via Xposed to block app start ups).
4. Is there a way of unlocking the phone from off, using the fingerprint scanner?
At the moment, I have to use a password (not pattern) and then use the scanner from sleep.
The Samsung Tab S2, allows a pattern or password from off and then the scanner from sleep.
5. The handwriting to text converter in S-Note as been removed in MM.
Thanks for any help.
Reply to your 2nd question :
Download a app called 'profile scheduler +' from google playstore and install it. Edit the normal profile according to your needs. Then edit any other profile and give it DND as the name. Configure the various settings for DND profile and save it. Then create a new rule. Set the activation and deactivation time. Set the rule type as scheduler. Save it. Make sure that the new rule is prefixed with the green symbol in tasks list of the profile scheduler + app. If you like, purchase the pro version which will come without ads. It is cheaper too. Enjoy.
Reply to your 3rd question :
Download and purchase (to disable the in app ads) app cache cleaner pro app from the google playstore. Configure it so that the app which uses maximum cache space is shown first (size descending order). Just make the app to manually scan for temp / cache files.
"Go to the individual app properties in the settings --> application manager (in android 6.0.1) and tap on storage. Then choose clear cache"
Do as said (in double quotes) for each and every app.
What to do man?. Google is removing all essential features :
Android 4.3 - Access to flight mode by all third party apps is disabled
Android 4.4 and its sub versions - Write access to the memory card by all third party apps (lile x-plore, es file manager, bookmarksb pro, app backup and restore pro etc) was also blocked
Android 5.0.1 - battery draining quickly
Android 6.0.1 - Disabled all third party apps to access the bookmarks of the stock browser. Because of this, the facility to import the bookmarks (from the stock browser) to the android firefox is also missing in the firefox settings under android 6.0.

Thank you very much. I'll try that out.
I couldn't find "profile scheduler +", but I guess you mean this https://play.google.com/store/apps/details?id=com.wetpalm.ProfileScheduler
The other 2 apps called "profile scheduler" seem to be for audio only.
Yes. The same app. Enjoy. I think buying option is within the app.

OK, thanks.
I've just tried the app, but I can't make it switch off mobile data at a scheduled time.
If I do other things within the same rule, like switch on WiFi, switch off BT and increase brightness, they all work.
So I know I've created and activated the rule.
For #1, you can use Firefds Kit xposed module.
For #4, you can use No Lock Home xposed module (but only works when connected to wifi).

Awesome, thank you.
Firefds Kit, is a million times better than the current version of Wanam i.e. most things work on MM.
I've not tried the other one, I don't leave WiFi on.
Have you also lost notification previews by any chance? I'm unclear as to whether this is just me or the same for everyone.

There is option to switch off the mobile data, wifi, sync, GPS etc. See properly.

I see the settings, but can't trigger to stop Mobile Data. The others, like WiFi can be triggered.
I've also installed Tasker and Secure Settings, to try and alter Mobile Data.
But, Secure Settings (which I think is needed to alter things like Mobile Data & GPS), says I need to root the device.
I think the problem with apps like Clean Master, Cache Cleaner Pro, Profile Scheduler, Tasker and Secure Settings, they all need root access to alter system permissions.
I've got root, but they aren't triggering Super SU to allow root and so those apps think I'm not rooted. And don't work properly.
Clean Master and Cache Cleaner Pro, appear to clear the cache, but they don't delete anything.
Maybe the problem of not seeing root, is something in MM or maybe it's because I'm using the latest beta version of Super SU?
See this
See the attached file of the profile scheduler + app.

Yes, I see the menu on my phone too. Except I've altered the Mobile Data to off and there's an empty circle to the right of the screen.
Hey. Just tap on the circle. The value will change to no change, yes or no.

I have done that.
Off = empty circle
No change = yellow circle
On = green circle
As a test, I've set Mobile Data to off and WiFi to On, within the same rule, to trigger at a set time.
When I run the test, the WiFi switches on, but there's no change with the Mobile Data.
I've a different question, if you wouldn't mind answering:
Is it possible to configure a long press of the recent apps to show the multi/split window screen, instead of the wallpaper/widgets/home screen settings screen (like when you long on the home screen)?
When I do the above on the tablet, I see the multi/split window screen.
I think mobile data is indirectly controlled by android restriction. I didn't use that restriction. If you want to cascade view a app, just rub the display with a single finger from top right to the bottom left.

No it's not the cascade view.
I see this type of multi window screen on my Tab S2, when I long press the recent apps button.

You may have to root via system-mode rooting not system-less rooting. Some apps like Tasker's Secure Settings doesn't work with system-less rooting.
There are SuperSu versions that uses system-mode rooting. But you also need a permissive kernel like Xceed and H-Vitamin in order to properly install the system-mode rooting.
But I think even after successfully rooting your device, third party apps cannot still turn off the mobile data. You can only put it to airplane mode at specified times to disable mobile data.

Device Administrators - Locked Screen Problem

Hi, I have an issue enabling/disabling device administrators on my device. Whenever I want to activate/deactivate device administrator for an app, it will lock my screen automatically and I couldn't use my fingerprint to unlock.
For instance, I want to enable device administrator for Tasker. When I go in device administrator, it will show a list of apps. When I click on Tasker, before I could select activate, my phone automatically lock itself. Hence, I couldn't activate/deactivate anything. Is there something wrong with my phone? Thank you for your help.
Well, i've seen this case happened to my colleague's phone. It was caused by a malware disguising as antivirus. He granted device admin without knowing the consequences, thus control of device admin was taken over. Please carefully examine list of apps in device admin for suspected app. If that is the case then it would be easier for the issue to be sorted out on a rooted device. If not, try these possible options :
1. Try boot in safe mode, force stop and try to remove the suspected troublesome app.
2. Alternatively, you may try package disabler app to remove it
I'm no expert by any means, so others are probably more competent to provide solution
Yea, managed to solved it by removing apps in safe mode. Thanks for your help.

Allow <app> to enable Bluetooth? Turn off user confirmation in Android P.

Since updating to Android Pie, apps need user confirmation when changing system settings like turning on bluetooth.
This defeats the purpose of automating processes with apps like tasker.
Had been looking for the solution on the web for a while and had not found any posts providing a solution.
I saw others with similar problems, but no solution that worked.
I found a solution and want to share it here.
The issue can be resolved in the following manner.
You need to give the specific app permission to write system settings.
Go to Settings>Apps>Apps.
Press the three dots at the top right.
Special Access>Write System Settings
Search for the app (e.g. Tasker)
Activate the setting for the app.
When the app activates Bluetooth, it will no longer ask for user confirmation.
Hope this helps people out there.

Hi in my case it doesn't work.
Honor 8 pro with Android 9.0.1.161, using an NFC tag that turns Bluetooth on or off, using the "NFC Task" app, whenever the system displays a screen with the text "NFC task wants to enable / disable bluetooth" and two choices "allow" or "refuse".
Steps dont work in my Huawei Y9 2019, with Android 9.01, any other suggestion?, write access settings are ON for all the apps that needs bluetooth, but bluetooth keeps asking the same, aprove or deny...
Same here, Mate 20 X. Had this already turned on.
Don't Work P30 Pro Android 10
Anyone was able to find a solution?
