I have a Nexus 4, which I've had for a almost a year. I like the phone, but I've run into a problem. Sometimes I will receive a notification for a new text. When I press it, I'm taken to the home screen of the SMS app, with no new messages in conversations. I'm sure a text was supposed to go through because they will ask if I've gotten their texts. This happens primarily with group messages, but occasionally happens with individuals. I own a Nexus 4, with coverage from T-Mobile. I use the stock SMS app, although I used to use third party apps (Go SMS and hello). Does anyone here have any idea what's going on and how I can fix it?
