A30s Infected - Samsung Galaxy A30s Questions & Answers

Hi Guys...
I installed an application called Brelo, which promises the loan, the problem is that the application in question behaved like a virus, and now it takes over my device, disabled all administrators and enabled only itself as an administrator. Result: I can't uninstall or disable it, oh, it also disabled the USB, in short: I don't know what to do...!
Help..!!!

English only please.

So you're locked out of doing a factory reset?
Can you access factory reset on the boot menu, if so do it from there. I doubt the malware has/can lock that option.
That's a nasty critter...

[Q] ICS Official: No Device Administrator Settings

Hi,
Is this a known issue on Android 4.03 Official?
I can't uninstall an app, because I can't disable its administrator privileges. These settings are gone after applying the FOTA!
Not noticed it but I did a factory reset after getting the update

But do you see the "Device Administrator" settings?
You mind trying to install this app (SwitchPro Widget) and then uninstall it?

Where's My Droid is the problem
I noticed after installing Where's My Droid and granting it Device Administration privileges, the option itself disappeared from the Security menu of my phone, along with Unknown Sources option. WTF - I reset my phone over a dozen times (literally) before I realized what caused it to keep disappearing. There's no telling how many apps out there that might cause these options to disappear after being added as a Device Administrator. So please, test my conclusion...reset your phone and if the options reappear, try installing the app that caused the options to disappear (most likely a security app or phone locator app) then grant it Device Admin again and see what happens. If I'm right, please hit the thank you button. Peace!!
I don't see this menu even I did factory reset+wipe data in stock recovery ... I've tried to check it on clean phone without any application installed and it is not there - just setting for "Unknown sources" but not Device administrators ..

Me either until you install an app like Where's My Droid, then go to the Security section of WMD> Remote Wipe or Remote Lock. DO NOT 'SET DEVICE ADMIN' but this should put the option in the Settings>Security menu of the phone. but after uninstalling WMD it goes away. maybe you can make use of it for programs that need device admin privleges while WMD is installed, hopefully it dosen't disappear if you authorize a different app, then hopefully uninstalling WMD wont remove the option if a different app already has admin rights. Are you pickin up what I'm layin down? I know it sounds crazy, thumbs down ICS

I'm knew at posting and don't know if you hit the thanks button but it would be greatly appreciated. btw, this problem is not on any other ICS phone I've seen, just Vivid, rooted or not.

You have found the root cause of this "problem".. It is not a bug it is feature
That did it for me, too!
Just to confirm, I found a small app on the Play Store that wanted Device Admin rights (an app called "Lock Screen" which just provides a button to lock the device), went in to it's settings, enabled Device Admin rights and then the 3rd Party Apps and Device Administrator settings appeared in the Security Settings. Thank you!

Only Install Android Device Manager for enable this menu

I know when iam trying this i get the error "netzfehler" in german how did you root? and did you scale your dpi?
No I did not change dpi .. maybe this is the reason ?
I rooted by installing TWRP then wiping data ( this is to get rid out the boot looping issue ) then flashed SuperSU.
an by the way, I'm using 930F version

May be you can consider flashing back the Stock ROM and have your VR installed first then do the rooting again.

Edit: Found it internet works, but vr service still won´t start :´(
Well i am all out of ideas...
i installed the apps of my brothers s6 but no luck... everytime i plug the s7 out of the gear vr and press next the same error pops up... maybe if someone could spare vr services backed up via titanium backup it would work... for anything else i guess i have to wait for a software update or fix or whatever.

i was not able to reinstall it because of internet error

Did you play around with the dpi?
I read another thread on Oculus community forum... this issue occurred before even on other phones...
some says it could be coming from Oculus servers.
I tried to logcat the app ID 10072 that tried to read the DNS before displaying the network error.
also tried...
to fully reset the device
to run the app with/without Sim card,
with a VPN
deleting cache...
no luck so far
I read that the Facebook app has to be installed or enabled can someone confirm this ? and try to log in and launch the setup wizard ?
if don't have a Facebook account.

No, you only need com.facebook.appmanager and com.facebook.system services. Not the Facebook app itself.

edit:
How do I turn on App Manager and Installer ?
To turn on the App Manager and Installer, tap on the "Settings" application, then "Applications" and finally "Application manager". Make sure you have chosen the "All" category and find the following applications:
com.facebook.appmanager (App Manager)
com.facebook.system (Installer)
Tap into each and make sure they are enabled.
Unable to find com.facebook.system
If you are on Android OS 6.0 (Marshmallow), com.facebook.system may not be visible. Please try the following steps:
1. Navigate to Settings
2. Tap on Application Manager
3. Tap the More menu in the upper right corner
4. Tap Show System Apps
5. This will make com.facebook.system visible and allow you to enable it.
The App Manager and the Installer must be enabled before Gear VR apps can be installed and updated on your mobile phone.

How prevent from system auto upgrading?

Hello everybody,
i just wanted to deactivate the automatic system updates of my Honor View 10 temporary.
So i searched global in this forum and found a solution.
See here please:
https://forum.xda-developers.com/showpost.php?p=75898824&postcount=7
It worked with the command. But how to enable the system automatic updates again?
There is no field anymore in the system menue of my Honor View 10 .
I pm'ed the user who has given the command, but he was some days not online.
I also use that command with "install" instead of "uninstall", but that gave me an error.
I am desperate.
Is there anyone who can help me?
Thanks in advance.

Hello Sir,
the developer options were marked for system update. But it didn't help. I did a restart my phone.
I am missing a field that is called "system update" to do it manually.
Ok, i can't insert an image to show you, because i am a new user here.
I have a red circle near the menu system. But when i go inside, the field is missing.

If you don't see the toggle "Automatic System Updates" (Settings > System > Developer Options > Automatic System Updates), I'm guessing it's due to that ADB command you'd done previously.
AFAIK, you'll need to perform either a factory reset or, dirty (re)flash the stock ROM to bring it back....

If you're fortunate enough to be able to Bootloader unlock your phone,install TWRP & Root your device, a better option is available for those who stay on the stock ROM:
Apps such as SD Maid Pro & Titanium Backup Pro allow for app freezing/disabling, virtually the same as the ADB command method you used, with one huge advantage:
The app freezing/disabling is easily reversible without the need for a factory reset.

Unlock Bootloader ist yet not an option for me, because of warranty.
Luckily i have the code to unlock it, but not for now.
I will do it, when warranty is over.

Question Install CA Certificate - Unable to find application

I wanted to install an AdGuard CA Certificate to filter the https traffic and keep getting the "Unable to find the application to perform this action" after pressing "Install anyway." Any idea what might that be? Thank you!
Same here.
Did you disable some apps via adb?
I had the same issue and no matter where I saved the certificate to the phone would not find it. The only thing that fixed it was a factory reset.

Well, yes at first, and then enabled everything back, still no luck. I am wondering if disabling some arcane app makes it deregister from being a default.

ugh that's what I am totally trying to avoid.
I had the same issue. I think I debloated a sensitive apk. After turning the packages on, still nothing. The only solution was a factory reset.
I had a similar problem but on Note 20 Ultra (Android 12, oneUI 4.1) when I follow the steps to install Adguard CA certificate the file browser just don't list it no matter which folder I used on internal or External memory card.
I discovered a solution by accident .. when I renamed the certificate file from *.crt to *.cer
Same thing here, no idea why.
I'm on a Galaxy s22, Android 12
Edit:
Discovered the following were disabled
- com.google.android.documentsui
- com.sec.android.app.myfiles
I enabled both and it worked flawlessly
