"Not Verify" Message
i've found a solution to your problem:
so Here's the step you should follow...
Step1 : install gravity box, that depends on your android version [Pie, Oreo, Marshmallow, Kitkat etc.]
Step2: install "Xposed installer" & enable gravity box in modules then reboot your phone.
Warning: this will brick your phone if you don't root your phone them properly ( you can use "Root Checker").
Step3: after you reboot your phone, open gravity box and then go to "Advance Tuning" & enable "Master Switch" then reboot your phone again.
Step4: Open gravity box again, Go to: "Advance tuning", "Frame work" and find "Config_add_tee_watermark_state"
press the "Override" option and then check the "Overridden value" that will turn the watermark off ("Not Verify") to False
Step5: Reboot your phone again....
"Congratulations, your phone is now working as normal"
