My iPhone goes into downtime by itself
I get a notification randomly says something like 945 minutes remaining until downtime and then 5 minutes later my phone goes into downtime when I asked my parents they say that they didn't put my phone into downtime and I tried restarting it many many times and is not working so can someone please tell me what is going on with this stupid glitch. Thanks
