Still use phone during blocked hours via Chat heads
Both my daughters have Samsung Galaxy A7 running andriod with NF installed. I use blocked hours from 9pm, however they are able to bypass this block by using messenger and using chat heads. When a message is received, the persons picture appears on the home screen and even when the phone is blocked they can read and reply to messages.
I have disabled the settings however the chat head settings are in the app itself and not the system settings.
Getting really frustrated as they were up the other morning at 3am still messaging friends when I have it set to block.
Please can someone advise?
