I'm wondering if anyone can help me. I've only had my phone for two months and all of a sudden my alarm clock has stopped working. It looks like the phone goes into sleep mode. The reason I say so is because once unlock the phone it takes a while for the phone to update the time. For example i set my alarm for 7am. At 7.05am the alarm still has still not gone off and the time on the home screen will read 2.30 (depending on the time the phone goes to sleep). Once i unlock my phone and click on an app such as weather it will update to the current time. Has this happened anyone. I also suspect that the flip case could also be why the phone goes in sleep mode. Any help will be appreciated.
