Hey everyone, all of a sudden my notification bar ( the top bar that displays missing calls/new messages/ the time) is disappearing within 5-10 minutes of turning on the phone. Everytime i reset the phone it shows up for a few mins and then boom gone again. And also now when i get phone calls it rings but doesnt pop up that someones calling so I just see the home screen with no option to answer the call . Please help if everyone has a suggestion how to fix these issues. I have not downloaded any apps or made any modifications to the phone ( i wouldnt know how). This is a replacement phone but I have had it for more than 2 months. The only new app on my phone showed up by itself today it was google play replacing the old app store by itself. Thanks
