There’s literally an app does let’s you wipe your phone for a period of not unlocking your phone (Its called “Wasted” available on Fdroid), so there has to be one that could do a reboot (without the wipe), right? 🤔
(If not, can anyone of you try to make one? I’m kinda jealous of Apple having that feature built in to iPhones. 😓)
I have no idea if this app works but here’s something i found for you
