So today I missed the ACT (October 27th) due to my phone alarm apparently not going off. The night before I had checked everything on my phone (volume, alarms, notifications) and made sure that it was set to the right time to wake me up at. I had the volume set to max and I set 2 additional alarms just incase something happened to the first. So I go to sleep thinking everything is ok. However I end up waking up at 8:16 AM EST (ACT started at 8 AM) and realized I just missed my ACT testing. I was freaking out and was beating myself for what must have gone wrong, until I realized it wasn't my phone's fault or mine. The timezone on my phone had switched back an entire four hours overnight. Is this a problem on ZTE's end or the carrier? I had my phone set to automatic time zone.
edit: I don't have a plan and I'm not currently signed onto any service with my phone, as I use it just for apps and web browsing.
