Foce removing device administrator app [no root]

[AC Question]

App doesn't come off the Play Store. It installed with a different (wanted) app. App is called ebony_f*ck and just before attempting to remove as administrator, it lists that it has access to "lock the screen".
After pressing "Deactivate", phone locks.
Power button is pressed to turn screen back on, then turns off automatically. This happens about five or six times before the phone becomes usable again.

I don't feel comfortable having such an app on my phone and I don't know what other privileges it has.

Safe mode doesn't solve the problem.
Would like to preserve as much data as possible, even in- app data which is why backup and factory reset has not been performed.

Running 5.0.1 on Samsung S4 stock, no root.

Myself having to post this is me pulling at the last straw. I've tried and tested all existing threads available.

Please please help!!!

so you can't deactivate the admin permission? because you won't be able to uninstall it if it has admin

this kind of apps root your device then unroot it, I guess you're facing this kind.
root or factory reset it.
