i have searched.but cannot find what will work on this phone correctly. what i am looking for is an app that will block email and all calls and sms except those that i put in the exemptions or whitelist and will be on a schedule to turn on at a certain time and off in the morning.i have tried 4 or 5 already from the play store but they don't work for this phone because of the way our call volume is linked to our notifications sound, they will not allow text messages sounds to come thru from people on the allow list. the blocking mode built in does the same thing, calls on the exemptions come thru but texts from those same people will not make a sound. i know tasker will do this but that is an over kill for what i need because this is for my daughters phone and afraid of her changing other things in it. just looking for a simple app that works. i used to use night ringer pro on my old phones but same thing allows calls but not texts from the allowed to come thru.
