I would like to install a filter onto my kyocera duraxv extreme that will block installing new apps (but won't block uninstalling apps like adb does), and will filter the content of some appps which have built in browsers. The problem is that even though the filter has device admin permission, you can still easily disable it in settings. On other phones that I've seen, the filter blocks you from disabling it once you give it device admin permission, but for some reason, its not blocked on the duraxv extreme. Does anybody know why this is, and if there's any way of blocking access to device admin permissions in settings?

McMonster Which filter are you talking about?

Filter pulled from the quinn phone and a random parental controls app from APKPure to block installing apps

McMonster That would be why. Even the Livigent filter isn't fully protected, קל וחומר a random who-knows-what.

McMonster I don't know if there is a way to do it, but I know on the Extreme when you first set up the phone, on the language selection page you can press *#*#*# and it will enable additional options, including things that can be blocked with a password. I don't have one in front of me, but maybe that will have an option that will help. (If you didn't do that when you set up the phone you need to reset the phone and do it by setup)

Techgen
didn't work for me this ##*#

McMonster you can use the app block posted here and block the package installer and put password on the app

Anybody knows how to boot this device into fastboot? I tried adb reboot bootloader but it just reboots the device

You have to enter * # * # * # (star-pound-star-pound-star-pound) immediately upon resetting the phone, when it shows the "Select Language" screen, then click yes to allow device management. The phone can then be filtered by going to Settings>Business Tools>Device Control. The default password is 000000. You can block apps, disable software updates, installing apps etc.

4448641 but it doesn't block reset do you know a way to block reset? (I tried Google family link which blocks reset I though it will work beacuse this phone allows regular installations but wasn't able to launch the app) so I guess the olny way is rooting

resetting requires a password

family link wont work on this phone because google play services is not installed

4448641 yes but you can reset with a screen lock or the recovery menu

Hi1 that is true, the only option you have to block that is a filter from tag

4448641 the olny option is a teqloc filter beacuse livigent won't work for this phone or any phone except a classic or a exalt, but if we can figure out how to root this phone it will solve the problem

Is there an option to add apps after having meshimer filter?

Hi1 reboot to recovery, and from recovery to bootloader

whynot it boots the device into a weird screen but its not download or fastboot mode

Hi1 It's technically another version of fastboot. The terms fastboot and bootloader are the same. I think that that interface is specific to Qualcomm phones.

Hi1 the command to remove the lock screen this way you cant reset it that way
adb shell
su
settings put secure lockscreen.disabled 1
rm /data/system/locksettings.db
rm /data/system/locksettings.db-shm
rm /data/system/locksettings.db-wal
reboot

anonymous I can only run this command on a rooted device and I have no clue how to root a Kyocera if you know please tell me how
