Razer Phone 2 Scheduler Options

Hey, can anyone give me some ideas. I used to have a Sony phone that had a built in scheduler. Meaning I can set the time and the day of week that I want sound and other functions to change. Then it would change it back for me. I downloaded a few different apps but after a few days of working the phone always ends up on silent, even when the volume is turned up, its on silent. I have not found a setting built into the phone for this. If there is one please let me know so I can use that one, if not, thoughts on a decent app that doesn't require a phone restart every few days?

Thanks
